Heat naturally moves from warmer places to cooler places. Heat pumps use electricity to move heat in the opposite direction, from cooler places to warmer places, making the cool space cooler and the warm space warmer. Your refrigerator is a heat pump, moving heat from inside the refrigerated cabinet (cooler place) into your kitchen (warmer place). An air conditioner is a heat pump, moving heat from inside your home (cooler place) to the outside summer air (warmer place).
Heat pumps are also used to heat homes, taking advantage of the fact that in the spring, fall, and yes, even in the winter, there is some heat in the outdoor air. An air-source heat pump collects heat from the outdoor air, concentrates it via an outdoor compressor, and distributes it inside through an indoor room unit or a home’s ductwork. During the summer, a heat pump can operate in reverse, as an air conditioner, by moving heat from indoors to the outside air. Heat pumps require electricity to run, but can deliver more energy than they use.
Air-source heat pumps have been used for many years in nearly all parts of the United States, but until recently they have not been used in areas that experienced extended periods of subfreezing temperatures. However, in recent years, air-source heat pump technology has advanced so that it now offers a legitimate space heating alternative in colder regions. Over 300,000 heat pumps were sold in New England, New York, New Jersey, Pennsylvania, Delaware, Maryland, and Washington DC in 2015 alone.
The majority of people who install an air-source heat pump in their home do so to obtain an improved level of comfort. For example, they may wish to add air conditioning to a home, or to better heat or cool parts of their home that weren’t adequately heated or cooled before. And, popular ductless heat pumps installed throughout a home are zone-friendly – you heat or cool only the rooms you need to.
People who currently have conventional electric resistance or propane-fueled heating systems can save 50% - 70% on energy costs by heating with an air-source heat pump instead. At current fuel prices, oil heating households can save up to 30%. At current prices, natural gas-heating households won’t cut costs by using air source heat pumps.
Concordians also install heat pumps because the systems reduce carbon emissions due to heating by 30 – 70%. This is a result of the combined high efficiency of the heat pump technology and the relatively lower carbon content of electricity, compared to other heating fuels. Most households keep their existing heating system when they install heat pumps. On extremely cold days, the existing heating system supplements the heat provided by the heat pumps. The actual percentage of carbon reduction depends on the percentage of the home’s heating needs met by heat pumps, and the heating fuel being replaced.
Cold climate air-source heat pumps come in two varieties: ductless and ducted.
Ductless heat pumps, also known as mini-splits, have outdoor compressors and indoor wall, floor, or ceiling mounted units to distribute the warm or cool air. Because ductless heat pumps do not require the presence of air ducts, they can be installed in homes currently heated with a boiler or an electric baseboard heating system.

A central ducted heat pump can be installed in homes with air ducts. It looks and performs like a central air conditioning system, except that it can heat in winter as well as cool in summer.

Whether you choose ductless or ducted heat pumps depends on the characteristics of your home.
CMLP can put you in touch with Concord residents who have already installed heat pumps in their homes, and who would be happy to share information about their experience buying and using a heat pump. Contact Energy Specialist Pamela Cady at email@example.com or 978-318-3149 for referrals.
We suggest soliciting proposals from at least three heat pump installers. Before soliciting proposals, consider talking with Concord residents who have already installed heat pumps in their homes. CMLP’s Energy Specialist, Pamela Cady (firstname.lastname@example.org or 978-318-3149), can put you in touch with Concord residents who would be happy to share information about their experience buying and using a heat pump.
CMLP strongly suggests that you seek proposals from HVAC (Heating, Ventilation and Air Conditioning) contractors who can provide a letter or certificate from the manufacturer verifying that the installer has successfully completed at least 4 hours of manufacturer training within the last 5 years for the products they install. CMLP highly recommends that you request the installer submit this documentation to you with their proposal. The documentation will be required if you wish to apply for a CMLP rebate for your heat pump.
The following HVAC contractors have installed air conditioning and/or heat pump systems for Concord residents who have received energy efficiency rebates from CMLP in the past. CMLP does not have any knowledge of customer experiences with these vendors, and we do not endorse, nor have we pre-qualified these companies in any way. When requesting a proposal from a contractor, CMLP recommends asking for the documentation of the manufacturer training described above.
Consider asking the following questions:
Rebates are available to homeowners and renters for air-source heat pump installations in new or existing homes that meet the following eligibility requirements:
1. Use the installed air-source heat pump (ASHP) for heating consistently throughout the winter.
2. Work with an installer that has received manufacturer training for the products they plan to install in your home.
3. Install ASHPs from either of two lists of eligible equipment:
- Any ASHP on the Massachusetts Clean Energy Center’s Qualified Products List is eligible for a rebate from CMLP. The vast majority of these are ductless heat pumps.
- Any centrally ducted ASHP on the Northeast Energy Efficiency Partnership’s (NEEP’s) Cold Climate Air Source Heat Pump (ccASHP) Specification Listing. Download the Excel file “ColdClimateAir-SourceHeatPumpSpecificationListing-Updated DD.DD.DD.xlsx at http://www.neep.org/initiatives/high-efficiency-products/emerging-technologies/ashp/cold-climate-air-source-heat-pump. In the filename, “DD.DD.DD” will display as the date when the file was last updated. Column M, entitled “Ductless or Centrally Ducted” must indicate that the ASHP is Centrally Ducted in order for the ASHP to be eligible for a CMLP rebate.
4. Has had a home energy audit completed within the last four years or have one scheduled within six months of project completion. New homes and multi-family residences with more than four units do not require an energy audit. CMLP recommends that priority recommendations from the audit are implemented before, or in coordination with, the installation of the ASHP. To schedule an audit, natural gas users can contact MassSAVE at (866) 527-SAVE (7283) or www.masssave.com/en/saving/energy-assessments/. All others can sign up with Energy New England at email@example.com, (888) 772-4242, or www.ene.org/residential-audits/.
Rebate Type Eligibility:
If the project meets the above eligibility requirements, system owners should next determine which rebate type they are eligible for based on the following table:
Income-Based Thresholds by Household Size
Annual Gross Income

**To receive an income-based rebate, the residential customer must complete one of the accepted income verification methods. Please see the “How Do I Qualify for an Income-Based Rebate?” question below for more information about income-based rebates and income verification.
*** Residences may install more than three single-head ductless systems, though the rebate will only support the first three installed. Rebates for central or multi-head systems are limited to 48,000 BTU/hr of heating capacity (maximum heating capacity at 5°F). Residences may install systems with greater capacity, though the rebate will only support the first 48,000 BTU/hr of heating capacity installed.
****For the purposes of determining rebate levels for central or multi-head systems, CMLP uses the system’s maximum heating capacity (BTU/hr) at 5°F.
Customers may apply for more than one ASHP rebate over the life of the ASHP rebate program. However, a customer may receive only one ASHP rebate within a twelve month period. This policy is subject to change in the future.
There are 3 steps to the application process:
First select an ASHP installer, who can help you with your rebate application. CMLP recommends that residents:
Prior to deciding to move forward with a system, residents who may meet income criteria should determine if they are eligible for the Income-Based Rebate, as described under the “Who’s Eligible for a Rebate?” question above. For example, a household of four with annual income of $132,230 or less may qualify. If eligible, complete one of the three income verification methods described in “How do I qualify for an Income Based Rebate?” question below.
Work with your installer to select eligible equipment from either of two lists:
Once you select an installer and are ready to move forward with the project:
Within 90 days of project completion, residents, with assistance from their installer, should complete and email the following documents to Energy New England, CMLP’s rebate processor, at firstname.lastname@example.org or postal mail to Concord Rebates c/o Energy New England, 100 Foxborough Blvd #110, Foxboro, MA 02035.
The Town of Concord assumes no liability for any equipment, installation or damages, and may inspect equipment to verify the above information at any time up to 1 year after receiving the rebate application.
In the interest of increasing access to air-source heat pumps to all residents of Concord, CMLP offers additional incentives for households with income below 80% or 120% of the state median income. Eligibility thresholds are determined based on household size. Eligibility for the income-based rebate is based on the income of the System Owner’s household.
Eligibility is based on total household income (Tax Return Form 1040 line 22), as determined by the System Owner and Household Members’ federal income tax filings for the most recent year available For rental properties, if the tenant is directly contracting with the installer for the installation of the project, the tenant would be the System Owner. Each System Owner household is only eligible to receive the income-based rebate at one residence per 12 month period.
Income-Based Rebate Adder Thresholds by Household Size
80% of State Median Income
120% of State Median Income
To receive the Income-Based Rebate, the System Owner must complete one of the following three income verification methods:
CMLP offers the R-7 “Electric Resistance & Heat Pump Heating Systems/DHW” rate for heat pump users, a special winter rate designed to prevent an unintended spike in electricity charges for electric heating customers as a result of CMLP’s tiered rate structure. This rate may benefit you if you already use more than 600 kilowatt-hours in some winter months, or if you expect to do so once your heat pump is installed.
However, In order to take advantage of this rate, you must request that a separate meter be installed by CMLP. This meter will record the electric usage of your heat pump. Electricity use recorded on this meter from October 1st through May 1st will be subtracted from the normal billing meter and billed at $0.14431 per kWh. From May 2nd through September 30th, the use through this meter will be billed under the regular R-1 Rate, which ranges from the tier 1 rate of $0.14431 to the tier 3 rate of $0.18685 per kWh, depending on how much electricity your household has used that month. CMLP’s R-1 rate schedule describes how your electric rate changes depending on how much electricity your household uses in a given month.
CMLP will supply and install the separate meter at no cost to you. However, you will need to pay an electrician to install a meter socket for the new meter. An additional electrical panel is typically needed as well. Costs for a meter socket/electrical panel can range from $1,000 to $4,000. The time it will take you to recoup the cost of the new meter socket/panel through electricity cost savings depends on several factors:
Please note also that customers who have a solar array usually expect that solar electricity will lower the portion of their electric bill attributable to the electricity needed to power their heat pump during the winter. However, if a heat pump is separately metered so that a customer can receive the Electric Resistance & Heat Pump Heating Systems/DHW rate for winter usage, CMLP is unable to offset the winter usage measured by the separate meter with solar electricity generated by the array. Therefore, having a solar array will not lower a customer's winter bill for heat pump electricity usage if the Resistance & Heat Pump Heating Systems/DHW rate is in effect. During the summer, when the Resistance & Heat Pump Heating Systems/DHW rate does not apply, solar electricity will offset the portion of an electricity bill due to a heat pump being used for air conditioning, even if the heat pump is separately metered.
Further, heat pump customers with solar would need to locate the second meter next to the existing house meter in order for the solar electricity powering the heat pump to be accounted for properly. This can require longer wire runs that increase the cost of the meter socket installation.
Please consider these factors when deciding whether to invest in a separate meter/electric panel.
If you have further questions about the Electric Resistance & Heat Pump Heating Systems/DHW rate, please contact Carole Hilton, Customer Service Coordinator, at (978) 318-3158 or Chilton@concordma.gov.
Yes! Ground-source heat pump rebates are available to Concord residents and small businesses. Find out more about ground-source heat pumps here: http://www.concordma.gov/1975/Ground-Source-Heat-Pumps.

No. The Central Air Conditioning rebate program for air-conditioning-only systems was discontinued on September 9, 2017 in favor of the new Heat Pump rebate program. Since the additional cost of an air-source heat pump over a cooling-only system is modest, CMLP encourages its customers to purchase versatile heat pumps rather than cooling-only systems. In addition to increased comfort (and cost savings for some customers), the use of heat pumps to heat as well as cool will reduce greenhouse gas emissions, helping Concord meet its goal of 25% fewer emissions by 2020 and 80% fewer by 2050.
CMLP discontinued the former Residential Central Air Conditioning / Heat Pump Rebate Program on September 9, 2017. However, we will still accept applications under that program for any compliant cooling-only systems or heat pumps installed through the end of 2017 in order to accommodate sales activity or installations in progress when we discontinued the program on September 9, 2017.
The rebate application for any cooling-only system or heat pump installed before the end of 2017 must be received by CMLP within one year of the equipment purchase date in order to be eligible for a rebate.
As described in the CMLP Strategic Plan, CMLP is purchasing Renewable Energy Certificates (RECs) to help green our power supply. Renewable Energy Credits (RECs) are tradable, non-tangible energy commodities that provide proof that 1 megawatt-hour (MWh) of electricity was generated from a renewable energy resource and was fed into the shared system of power lines which transport energy. Solar renewable energy certificates (SRECs) are RECs that are specifically generated by solar energy.
This YouTube video from the U.S. Environmental Protection Agency RECs: Making Green Power Possible explains why RECs make power green.
CMLP changed to monthly billing for two reasons:
Yes, your water/sewer bill will be changed to monthly beginning in July 2018.
Effective January 1, 2017, there was an increase of $0.0125 per kilowatt hour to the Capacity and Transmission charges across all rate classes. Additionally, the Rate Stabilization Fund charges ended, and CMLP is now issuing a $0.0040 per kilowatt hour credit on customers' bills effective 03/01/2018.
CMLP buys its electricity from a number of generating sources which produce electricity by utilizing a number of power sources: - Hydro - Land fill gas - Natural gas - Oil - Solar - Wind
Because the costs associated with each source’s generation are not constant (the cost of fuel used to generate electricity can fluctuate dramatically), CMLP may use a Power Cost Adjustment (+ or -) or a Purchased Power Adjustment (+ or -) to recover fluctuations in wholesale power and transmission costs which represent about 80% of CMLP's costs.
As these costs either increase or decrease, the PCA or PPA factor changes to insure these costs are covered and at the same time are revenue neutral to CMLP. Any questions regarding these adjustments should be directed to

The Customer Service Administrator,
Heat naturally moves from warmer places to cooler places. Heat pumps use electricity to move heat in the opposite direction, from cooler places to warmer places, making the cool space cooler and the warm space warmer. Your refrigerator is a heat pump, moving heat from inside the refrigerated cabinet (cooler place) into your kitchen (warmer place). An air conditioner is a heat pump, moving heat from inside your home or business (cooler place) to the outside summer air (warmer place).
Heat pumps are also used to heat homes and businesses. A ground-source heat pump (GSHP) takes advantage of the fact that although many parts of the country experience seasonal temperature extremes -- from scorching heat in the summer to sub-zero cold in the winter—a few feet below the earth's surface the ground remains at a relatively constant temperature. Depending on latitude, ground temperatures range from 45°F to 75°F. Like a cave, this ground temperature is warmer than the air above it during the winter and cooler than the air in the summer.
GSHP systems consist of three parts: the ground heat exchanger, the heat pump unit, and the air or hot water delivery system (ductwork or piping). The ground heat exchanger is a system of tubes called a loop, which is buried in the ground near the building. A fluid (usually water or a mixture of water and antifreeze) circulates through the tubing to absorb or relinquish heat within the ground. GSHPs require underground trenches or wells to operate, and a property needs to have sufficient space and the right geological conditions to support them.
In the winter, the heat pump extracts heat from the heat exchanger and pumps it into the indoor air or hot water delivery system, moving heat from the ground to the building's interior. In the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger, effectively moving the heat from indoors into the ground. The heat removed from the indoor air during the summer can also be used to heat water, providing a free source of hot water for sinks, showers, clothes washers, etc.
Heat pumps require electricity to run, but can deliver more energy than they use.
There are approximately 50,000 GSHPs installed at homes and businesses in the United States each year. As of late 2017, CMLP was aware of 21 private homes heated and cooled with GSHPs in Concord.
These high-efficiency systems can provide 100% of a building’s heating and cooling needs. Though they require electricity to operate, efficient GSHPs can provide the same amount of heat using 65 to 80 percent less electricity than traditional baseboard electric heating – and reduce greenhouse gas emissions and operating costs accordingly.
Concordians also install ground source heat pumps because the systems reduce carbon emissions due to heating. This is a result of the combined high efficiency of the heat pump technology and the relatively lower carbon content of electricity, compared to other heating fuels.
Although the installation costs can be substantial, incentives and can reduce these costs, and in some cases, customers are cash flow positive from the day the system begins operation. This is more likely to be true when your investment in a GSHP is included in a mortgage. Due to their high efficiency, GSHPs offer excellent long-term energy savings as well.
For further savings, GHPs equipped with a device called a "desuperheater" can heat household water. In the summer cooling period, the heat that is taken from the house is used to heat the water for free. In the winter, water heating costs are reduced by about half.
GSHPs also improve humidity control by maintaining about 50% relative indoor humidity.
Ground-source heat pump systems allow for design flexibility and can be installed in both new and retrofit situations. Because the hardware requires less space than that needed by a conventional HVAC system, the equipment rooms can be greatly scaled down, freeing space for productive uses. GSHP systems also provide excellent "zone" space conditioning, allowing different parts of your home to be heated or cooled to different temperatures.
GSHP systems have relatively few moving parts and those parts are sheltered inside a building, so the systems are durable and highly reliable. The underground piping often carries warranties of 25 to 50 years, and the heat pumps often last 20 years or more. They usually have no outdoor compressors, so GSHPs are not susceptible to operational problems due to weather-related issues such as snow cover. In addition, the components in the living space are easily accessible, which increases the convenience factor and helps ensure that the upkeep is done on a timely basis.
Ground-source heat pumps come in several varieties:
Ground-source heat pumps can move heat to and from the ground or to and from water (water-source), if there is a pond or other water body nearby. Local regulations apply.
Most closed-loop ground-source heat pumps circulate an antifreeze solution through a closed loop -- usually made of plastic tubing -- that is buried in the ground or submerged in water.
The loops can be horizontal or vertical, depending on land area available, soil conditions and other variables. If the site has an adequate water body, this may be the lowest cost option. A supply line pipe is run underground from the building to the water and coiled into circles at least eight feet under the surface to prevent freezing. The coils should only be placed in a water source that meets minimum volume, depth, and quality criteria.
Open loop systems use well or surface body water as the heat exchange fluid that circulates directly through the GSHP system. Once it has circulated through the system, the water returns to the ground through the well, a recharge well, or surface discharge. This option is obviously practical only where there is an adequate supply of relatively clean water, and all local codes and regulations regarding groundwater discharge are met.
The best system, loop length and design for a particular building depend on a variety of factors such as climate, soil conditions, available land, required heating and cooling load, and local installation costs at the site.
The indoor components of a ground source heat pump move the heat to and from the ground and around the house. These ground-source heating and cooling units were installed in the basement of a new home.
The costs for GSHP projects in the 2 to 10 ton size range average $12,000 per heating ton, with 50% of projects ranging from $10,000 to $15,000 per heating ton, 20% above $15,000 per heating ton and 30% below $10,000 per heating ton, depending on the site and project type.
It is worth comparing the return on investing in ground source vs. air source heat pumps when considering heating options for your home or business. An air-source heat pump moves heat to and from the outdoor air rather than the ground. While air-source heat pumps are less efficient, they also cost less. For comparison, contractors are willing to install a one ton air-source heat pump unit (one outdoor unit + one wall- or ceiling-mounted unit) for $4,000 - $4,500, including electrical work. However, contractor prices can range from $3,000 to $7,000 for a single air-source heat pump, with an additional $350 - $800 for electrical work.
CMLP can put you in touch with Concord residents who have already installed ground-source heat pumps, and who would be happy to share information about their experience buying and using a ground-source heat pump. Contact Energy Specialist Pamela Cady at firstname.lastname@example.org or 978-318-3149 for referrals.
We suggest soliciting proposals from at least three ground-source heat pump installers. Before soliciting proposals, consider talking with Concord residents and organizations who have already installed ground-source heat pumps. CMLP’s Energy Specialist, Pamela Cady (email@example.com or 978-318-3149), can put you in touch with Concord residents who would be happy to share information about their experience buying and using a ground-source heat pump.
Qualifications and Experience
Ground-source heat pumps installed at new or existing buildings are eligible for rebates, though the system must be used for heating (in addition to heating use, systems may providing cooling as well). Projects with a single heat pump serving multiple units in a multifamily residential or multi-unit commercial building can apply jointly with one application, subject to existing caps. A single apartment or condominium can also apply individually. Projects must have rated heating capacity no greater than 10 tons (120 kBTU/hr).
Project installation may not commence until after the application has been approved by CMLP and the system owner has received an award letter. Projects that have already commenced construction are not eligible for the rebate.
Energy Assessment Requirement
All existing buildings must have an energy efficiency assessment completed within the past four years or have an energy assessment scheduled to occur and completed within six months of project completion. CMLP highly recommends that priority recommendations from the assessment be implemented before or in coordination with the installation of the GSHP. Making a building more energy efficient can reduce the size and cost of the GSHP needed to heat and cool your building.
Households heating with natural gas can contact MassSAVE at (866) 527-SAVE (7283) or www.masssave.com/en/saving/energy-assessments/ for an assessment. Businesses heating with natural gas can find information about Mass Save facility assessment at https://www.masssave.com/en/saving/business-rebates/facility-assessments/
All others can sign up with Energy New England at firstname.lastname@example.org, (888) 772-4242, or ene.org/residential-audits/. Energy New England, CMLP’s energy assessment provider, provides no-cost home energy assessments, and business energy assessments at a 50% discount. CMLP covers 50% of the cost of a full-scale business energy assessment.
New buildings do not require energy assessments, although energy assessments are still recommended.
Rebate Type Eligibility
Rebate levels for GSHP systems are calculated per heating ton (12,000 BTU/hr). Residential rebates are limited to the first five tons of heating capacity per housing unit. Non-residential entities can receive funding for up to ten tons of heating capacity through this program. Income-based rebates are available for qualifying residential applicants.
$625 per 12,000 BTU/hr**
(up to a maximum rebate of $6,250)
(up to a maximum rebate of $3,125)
$800 per 12,000 BTU/hr**
(up to a maximum rebate of $4,000)
$1,500 per 12,000 BTU/hr**
(up to a maximum rebate of $7,500)
*To receive an income-based rebate, the customer must complete one of the accepted income verification methods. Please see the “How Do I Qualify for an Income-Based Rebate?” question below for more information about income-based rebates and income verification.
**For the purposes of determining rebate levels for GSHPs, CMLP uses the American Heating and Refrigeration Institute’s (AHRI’s) heating capacity for the system.
All applications must be submitted and approved by CMLP prior to starting project construction, and, to be eligible for a rebate, construction must not commence until an award letter is issued. Once the system owner has decided to move forward with the project, the installer should apply for a rebate on the system owner’s behalf.
First, select a GSHP installer, who will submit the rebate application on your behalf.
The following resources can help you identify potential installers:
In order for your GHSP installation to be eligible for a CMLP rebate, the following conditions must be met:
Your installer must submit a copy of the certificate for one of the accreditations listed above with the rebate application.
If not currently holding one of these credentials, your installer must provide references for three GSHP installations, including phone numbers and email addresses for each reference. Rebate approval is contingent upon a successful reference check. Installers must achieve one of the above credentials within one year of submitting their first GSHP rebate application to CMLP in order to be eligible to submit further GSHP rebate applications to CMLP.
2. Your installer must agree to fix any system defects or significant workmanship issues identified during the first year after the project completion date.
CMLP recommends that our customers:
In order to be eligible for a rebate, projects must meet the following requirements:
A. Equipment Requirements
a. In the application, EER and COP must be calculated using the following equations:
i. EER = (full load EER + part load EER) / 2
ii. COP = (full load COP + part load COP) / 2
b. EER and COP figures for the above calculations must use the AHRI rated ground loop heat pump (GLHP) figures for closed-loop systems and the AHRI rated ground water heat pump (GWHP) figures for open-loop systems.
3. GSHP systems must be designed with full-load heating capacity between 90% and 120% of peak heating load (BTU/hr for heating) according to the applicable heat load calculation. On a case-by-case basis, CMLP will consider eligibility of GSHPs installed at buildings with heating capacity sized below 90% of peak heating load if designed to operate in conjunction with back-up or peaking heating systems.
4. All GSHP systems must be installed by licensed contractors and/or plumbers in accordance with the National Electric Code and manufacturer’s specifications and must conform to all applicable municipal, state, and federal codes, standards, regulations, and certifications, as well as program requirements. At a minimum, a contractor must possess an EPA 608 license to handle refrigerant and an electrician license to complete the electrical work on the heat pump.
5. Blower motors must be multi-speed or variable-speed, high-efficiency motors. Motors qualify as “energy-efficient” if they meet or exceed the efficiency levels listed in the National Electric Manufacturers Association’s (“NEMA’s”) MG1-1993 publication. Single-stage water-to-water console units with a capacity less than 2 heating tons are eligible to be preapproved by CMLP, provided these types of units satisfy all of the other eligibility requirements described herein.
6. Systems must meet ANSI/AHRI/ASHRAE/ISO Standard 13256-1 for water-to-air models, Standard 13256-2 for water-to-water models, or AHRI Standard 870 for DX models.
7. All compressors must use two-stage, multi-speed, or variable-speed drives, unless they are water-to-water units. Single-stage water-to-water systems are allowed, provided they include accumulator tanks with the greater of ten gallons of capacity per heating ton or industry/manufacturer recommended best practice.
8. All GSHP systems receiving a rebate from CMLP must be covered by a minimum five-year manufacturer’s warranty.
9. CMLP may submit open-loop, horizontal-loop, and direct exchange system designs to a third-party consultant to evaluate a project’s design and reserves the right to submit designs of other system types for review. Installers should be prepared to work with the reviewer to answer any outstanding questions about the project’s design and must respond within seven days to any information requests.
B. Well Requirements
10. Vertically bored closed-loop projects must have a minimum depth of 150 feet per 12,000 BTU/hr of heating load served by the system (i.e., the lesser of capacity and peak load). Capacity must be determined using the method used to calculate rebate values (see Section A. 2. a under Step 2). This must be sufficient to maintain a minimum entering water temperature of at least 30°F, with a recommended best practice of at least 32°F. Direct Exchange (DX) systems require a minimum of 120 feet of borehole depth per heating ton.
11. Closed-loop bore grouting must have a grout conductivity equal to or greater than anticipated earth conductivity of the drill site up to 1 BTU/hr-ft-°F.

C. Open Loop Requirements
14. All open-loop GSHP wells shall be installed in conformance with MassDEP’s Private Well Guidelines (www.mass.gov/eea/docs/dep/water/laws/i-thru-z/prwellgd.pdf) (as amended) or MassDEP’s Guidelines and Policies for Public Water Systems (www.mass.gov/eea/docs/dep/water/laws/a-thru-h/glintro.pdf) (as amended), whichever is applicable. All GSHP wells shall be installed in conformance with 313 CMR 3.00: Certification of Well Drillers and Filing of Well Completion Reports (www.mass.gov/eea/docs/dep/service/regulations/310cmr46.pdf)
a. Open loop systems must register for a permit with the Massachusetts Department of Environmental Protection (“MassDEP”)’s Underwater Injection Control (UIC) program. The UIC registration number must be noted on the Project Completion Form at the time of project completion. Open loop systems installed on parcels of land used for single-unit residences are exempt. (https://www.mass.gov/underground-injection-control-uic)
15. A standing column well must include a bleed circuit and drywell to maximize thermal efficiency based on available water production
16. Applications for open- and horizontal-loop systems must explain the method for determining pressure and flow rate.
D. Horizontal-Loop Project Requirements
17. The Application must include the file from the horizontal-loop design software showing inputs and system design specifications.
E. Direct Exchange System Requirements
18. Direct exchange (DX) heat pumps, which circulate a refrigerant through a closed-loop copper pipe system (whereas most systems utilize plastic pipes that circulate water or a water antifreeze mixture), must meet the following additional conditions:
a. DX wells require cathodic protection ensuring a minimum expected well life of 20 years.
b. DX System Owners must certify that they will undergo an end-of-life decommissioning that includes full refrigerant recovery.
c. Each DX system must undergo a design review through CMLP’s third-party consultant.
d. The refrigerant must be R-410A. If the installer intends to use a different refrigerant type, CMLP will consider it when then application is submitted.
e. The entire well depth interval for DX wells shall be grouted with thermally enhanced grout that achieves hydraulic conductivity of 10-7 centimeters per second or less (per MassDEP).
f. A permanent placard must be attached to the heat pump unit, detailing:
i. Loop field refrigerant content, type, and volume;

iii. Loop piping material;
iv. Required maintenance schedule on loop field, refrigerant, and heat pump; and
v. Planned decommissioning date and process, consistent with loop field useful life.
g. The installer must provide a detailed operational handbook for the System Owner that provides an overview of system design, operations, and the information stated in 18.b. above.
F. Heat Load Calculation Requirements
19. Equipment must be sized with a building peak heating capacity (BTU/hr) calculated using the Air Conditioning Contractors of America (“ACCA”) Manual J (for residential) or Manual N (for commercial) building heat load calculation method.
20. Installers must submit the summary page of the applicable heat load calculation of the building’s peak heat load at the 99% dry bulb heating design temperature for the most relevant ACCA location. Heating set temperatures may be between 68 and 72 degrees Fahrenheit.
21. CMLP strongly recommends all projects incorporate system performance monitoring technology to help owners understand performance throughout the year.
CMLP may choose to monitor a subset of systems installed under this program. To be eligible for a rebate under this program, the system owner must agree to allow metering and monitoring to be conducted on their project for up to twenty-four (24) months after installation, if requested. The system owner will be required to submit fossil fuel bills for two (2) years prior to installation (for existing buildings) and for the duration of the performance monitoring. Monitoring equipment would be paid for and installed directly by contractors to CMLP with no direct cost to the system owner. Data would be collected and analyzed for program evaluation purposes and will not impact the rebate received by the system owner.
H. Deviation from Requirements
Although CMLP typically does not allow deviation from these design requirements, certain site characteristics may lend themselves to alternate system designs. If for technical reasons, a design requirement cannot be met for an installation, the installer may request a waiver. All variations must be explained in detail in the Project Notes field at the bottom of the application, and output from geothermal modeling software must be submitted. CMLP may send these applications to CMLP’s third party consultant for review and consideration.
I. Other Project Requirements
Installed systems must meet all applicable state and local laws and ordinances, including applying for and receiving a building permit and, upon project completion, receiving sign-off from a local building authority.
Step 3: Apply for a Rebate
Prior to deciding to move forward with a system, residents should determine if they are eligible for the Income-Based Rebate, as described under the “Who’s Eligible for a Rebate?” question above. For example, a household of four with annual income of $132,230 or less may qualify. If eligible, complete one of the three income verification methods described in the “How do I qualify for an Income Based Rebate?” question below.
Once the system owner has decided to move forward with the project, the installer should complete and submit the application on the system owner’s behalf, with the assistance and approval of the system owner. Application documents must be emailed to email@example.com. To expedite the review, please include “GSHP Application: [Project Site Name]” in the subject line. Both the installer and system owner should review all information before submitting it to CMLP.
All applications must be submitted and approved by CMLP prior to starting project construction, and, to be eligible for a rebate, construction may not commence until an award letter is received.
All complete applications must include:
1. Application Form: A completed Excel Application Form
a. Energy Assessment: Date of completed or scheduled energy assessment must be noted on rebate application. Assessments performed through CMLP’s energy assessment program, Concord’s Green Your Heat Program, the MassSave program or other energy assessment providers are all accepted.
i. If you believe you had an assessment in the last four years through CMLP, but do not know the date, contact Energy New England, CMLP’s assessment provider, at 1-888-772-4242 for assistance.
ii. If you believe you had an assessment in 2015 or 2016 through Concord’s Green Your Heat Program, but do not know the date, contact CMLP’s Energy Specialist Pamela Cady at firstname.lastname@example.org or 978-318-3149 for assistance.
iii. For the date of a MassSave assessment, call 800-632-8300.
iv. To schedule an energy assessment, call Energy New England, CMLP’s assessment provider, at 1-888-772-4242.
2. Contract: Installation contract signed by both the system owner and the installer
3. Electric Bill: A copy of a recent electric bill from the project site. New construction projects can submit the electric bill or a request for electric service at project completion.
4. Heat Load Calculation: The summary report from the Manual N (commercial) or Manual J (residential) calculation of the building heat load, as described in Section F under Step 2: Select Eligible Equipment.
5. AHRI Rating Certificate: A copy of the Air-Conditioning, Heating, and Refrigeration Institute (“AHRI”) rating certificate for each heat pump model installed.
Certain projects must also submit additional documents, as follows:
1. Income Verification: Residential Income-Based Rebate eligibility verification (if applicable). Eligibility thresholds and income verification methods can be found under the “How do I qualify for an income-based rebate?” question below.
2. Tax Documentation (if applicable) –
3. Design Reports: Horizontal-loops systems (if applicable) – Software design report showing all system inputs.
4. Flow Rate: Open-loop systems (if applicable) – Detailed estimation of well water flow rate.
5. Modeling Summary: Non-residential systems (if applicable) – Modeling software summary page.
Rebates can be paid to the system owner or to the installer, provided that the system owner provides written permission in the application. If the application meets all requirements of this program and funding remains available, CMLP will issue the rebate payment to the payee via mail.
The rebate may be combined with any other local, state or federal incentives, and applicants are encouraged to do so where possible. CMLP will not provide funding that would, in CMLP’s sole determination, exceed total project costs. Total project costs shall include all costs presented in the application, less all other available incentives, including any state or federal rebates, subsidies, and tax incentives, discounted to present value where necessary. CMLP will evaluate these situations on a case-by-case basis, and reserves the right to reduce any award projected to exceed total project costs by an amount sufficient to prevent the excess.
Step 4: Receive Rebate Award Letter
Upon receiving the application, CMLP staff will send two separate emails. The first email will confirm that the application has been received; the second email will indicate one of the following statuses:
Applications will be evaluated to ensure that the project will meet the eligibility and project requirements described above. CMLP reserves the right to accept, assign design reviews, or reject applications based on completeness, qualitative criteria, and available funding; to make no awards; to award less than the applicant requests; and/or to award less than the maximum amount of funds potentially available through this program. If CMLP elects to conduct a design review, the installer must be prepared to answer the reviewer’s questions about the project’s design and must respond within seven days to any information requests.
CMLP will notify applicants of their application status within four weeks of receipt of a complete application, barring extenuating circumstances. If the application meets all requirements of this program and funding remains available, CMLP will issue an award letter to the system owner and installer via email that will provide details on the award amount and, among other pertinent information, state which party will receive payment (the “payee”). CMLP will also attach a Project Completion Form, which will be submitted to CMLP upon project completion.
Step 5: Complete Project:
Project installation may commence only after receipt of the award letter. Projects must be completed within six months of the award date on the award letter for projects at existing buildings and within twelve months for projects at new construction buildings.
Upon project completion, the installer in cooperation with the system owner will complete and submit supporting documentation to CMLP, including:
1. Project Completion Form; and
2. Completed GSHP manufacturer or distributor start-up sheet. This documentation should be submitted by email to email@example.com with “GSHP Project Completion: [System Owner Name (residential) /Site Name (non-residential)]” in the subject line.
Step 6: Receive Rebate Payment:
Rebates can be paid to the system owner or installer, provided that the system owner provides permission in the application. Upon approval of the project completion documentation, payment will be issued to the designated payee within 4 weeks, barring extenuating circumstances.
In the interest of increasing access to ground-source heat pumps to all residents of Concord, CMLP offers additional incentives for households with income below 80% or 120% of the state median income. Eligibility thresholds are determined based on household size. Eligibility for the income-based rebate is based on the income of the system owner’s household.
Eligibility is based on total household income (Tax Return Form 1040 line 22), as determined by the system owner and household members’ federal income tax filings for the most recent year available. Each system owner household is only eligible to receive the income-based rebate at one residence.
To receive the Income-Based Rebate, the system owner must complete one of the following three income verification methods:
No, we don’t sell LED bulbs at CMLP. You can purchase them at hardware, home outlet stores, and other retailers.

Culinary Incubators are perfect during tougher economic times, as they allow businesses to cut back on hours of kitchen use, but still stay in businesses with reduced costs to meet reduced demand.
First, these facilities are not usually licensed, thereby they do not receive regular health department inspections, and may not meet the department’s specifications for commercial food production. Second, and equally important, is that these are non-profit organizations and therefore cannot legally rent out kitchen space for a for-profit business.

Fluorescent bulbs: All fluorescent bulbs, straight, U, circular, and compact contain mercury may be recycled at Concord Public Works located at 133 Keyes Road, weekdays 8:30 a.m. - 4:30 p.m. In addition items may be recycled at West Concord 5 and 10, during store hours, Vanderhoof Hardware and at the Composting Site.
Button Batteries: Small button batteries used in watches, hearing aids, laser pointers, and more still contain small amounts of mercury and other heavy metals. These batteries may be recycled at the Concord Town House, Concord Free Library, Concord Public Works, Harvey Wheeler Community Center and West Concord 5 and 10.
Intact mercury-containing devices, such as thermostats and fever thermometers, may be recycled at Concord Public Works located at 133 Keyes Road, weekdays 8:30 a.m. - 4:30 p.m.
Mercury that is not contained in a manufactured device, such as mercury from a broken fever thermometer, a jar of elemental mercury, and more should be taken to the Minuteman Regional Household Hazardous Waste Facility. Contact Concord Public Works at 978-318-3240 for more information on hazardous waste disposal.
Styrofoam block that comes with new products, such as computers and small household appliances, can be recycled at the Drop-off Days sponsored by ReUsIt and Concord Public Works each spring and fall if it is clean and dry. For information and Drop-off dates call Concord Public Works at 978-318-3240. Clean Styrofoam cups, trays, and takeout clam shells will also be accepted on DropOff Days.
Materials that go in the mixed paper compartment include any kind of clean paper item: - Newspaper - Magazines - Catalogs - Junk mail - Envelopes - White and colored paper - Fax paper - Phone books - Paperback books - Spiral notebooks - Clasp envelopes - Manila folders - Shoe boxes - Cereal boxes - Poster board - Corrugated cardboard, and more.
Plastic windows, self-stick labels, and staples are accepted. Cardboard must be flattened and smaller than 36 inches by 36 inches in order to fit in the compartment. Household product containers include 4 types of containers: glass, metal, plastic, and aseptic cartons. All these containers may be mixed together in a single bin.
Glass containers include clear and colored bottles and jars with lids removed (you do not need to remove metal collars). Metal containers include deposit and non-deposit beverage cans, metal food cans, and metal jar and can lids. Plastic containers include any plastic bottle or jar except those used for motor oil or other chemicals. It also includes other plastic containers, such as plastic take out food containers (except those made from styrofoam). Aseptic cartons include paper milk and juice cartons as well as empty juice boxes that have had the straws removed. Please remember that all containers must be rinsed clean.
Please do not recycle the following items: - Plastic bags - Styrofoam (cups, trays, block, or packaging peanuts, even if marked #6) - Plastic containers for motor oil or other hazardous chemicals, or soiled paper (such as paper plates, cups, towels, napkins, tissue, or paper with paint or glue).
Pizza boxes can only be recycled when they have absolutely no grease or other food waste and are turned inside out so they look like a regular piece of cardboard.
Better than recycling bags, of course, is reusing bags or using reusable shopping bags. It is notoriously difficult, even for those with the best of intentions, to remember to bring reusable bags on a shopping trip. Here are some tips to help you remember: - Write on your shopping list "remember to bring bags." - Hang cloth bags on your kitchen door. - Hang your purse on the same hook where you hang cloth bags. - Use a cloth bag to hold deposit bottles and cans, that way you will have at least 1 cloth bag with you when you get to the store. - Tape a reminder on your dashboard. - Don’t get discouraged when you keep forgetting your bags. Keep trying.
Cardboard may be recycled at the Composting Site on Walden Street (just across Route 2) on Saturdays between 9 a.m. to 3 p.m., April through November, and in the dumpsters at the public parking area at the Public Works facility, 133 Keyes Road, which is open 24 hours a day. Please flatten boxes and remove all non-cardboard materials, such as styrofoam, wood, plastic, and other packaging. Please do not recycle pizza boxes and other types of paperboard at this location.
Latex paint is not a hazardous product, so the only latex paint the shed will accept is latex paint in good enough condition that you can imagine using it in your own home. If there is very little paint in the can, or the paint is dried out, throw the can away with your regular rubbish. If there is more than ¼ can but it is not in good condition, or if the paint has been frozen, you must dry it out, then dispose of it with your regular trash. To dry it out, add kitty litter or a latex paint hardener typically available at Concord Lumber, Vanderhoof Hardware or other paint suppliers, then dispose of the can with your regular trash.
Oil and alkyd-based paints and stains are hazardous products. If the can is empty you may throw it away with your regular trash. If the can is more than ¼ full, no matter what condition, bring the can to the paint shed for reuse, recycling, or proper disposal. Other paint products, such as primer and sealer, polyurethane, shellac, wood and deck preservatives, paint remover, unused paint thinner, and unused mineral spirits, are also accepted for reuse, recycling, or proper disposal at the paint shed. These items are flammable and should never be disposed of with your regular trash unless the can is empty or the materials are dried out. Paint thinner or mineral spirits that have been used to clean brushes should be taken to the Minuteman Hazardous Waste Facility for proper disposal.
The Paint Shed does not accept any other hazardous material. Other hazardous products, such as epoxy, floor finish, and more must be taken to the Minuteman Regional Household Hazardous Waste Facility in Lexington, which is open to Concord residents 1 Saturday per month April through November. For more information on disposing of hazardous materials call Concord Public Works at 978-318-3240.
Many charitable organizations will pick up furniture, household items, and clothing at your home if you have sufficient quantities. Look in the yellow pages or contact Concord Public Works at 978-318-3240 for a list of charitable organizations that pick up at homes.
Household items and clothing may be dropped off at the Goodwill trailer at Crosby ’s Supermarket daily between 8 a.m. to 4 p.m. Clothing may also be dropped off at the Red Cross drop boxes located at Papa Razzi and the West Concord Train Depot and at the Salvation Army clothing drop box at the West Concord train depot. All items should be clean and in good, usable condition. Household Goods in Acton is the closest organization that accepts furniture. They also accept household goods. Call Household Goods in Action at 978-635-1710 or visit the Household Goods website.
If you cannot wait until 1 of the Drop-off Days, contact the manufacturer or retail outlet. Best Buy and Staples are the retailers that have electronics recycling programs. Many computer companies now have programs in place where computers can be shipped back for proper disposal. There are also electronics recycling companies that will accept electronics for a fee. Call Concord Public Works at 978-318-3240 for more information.
Subscribers to the program pay only for the trash that they discard. Residents save money and protect our environment by recycling and reducing their disposable trash. For further information about subscribing visit the Trash and Recycling page.
First, you want to check for leaks. The “usual suspects” for leaks are toilets and in-ground irrigation systems. If no leaks are detected, then you can do some sleuthing by using your water meter. Most water meters are located in basements near the wall closest to the street. They can also be in a utility closet, mechanical room or outside in a pit in the ground. In Concord, the meters measure water use in cubic feet (CF). One cubic foot equals 7.48 gallons. You can use your meter to track water usage throughout the day or week to determine when a lot of water is being used. Are evening baths the culprit? Daily loads of laundry? Or morning lawn watering? Still baffled? CPW offers free water use audits to residential customers. Call 978-318-3250 to schedule an audit.
Payments can also be made in person at the Town House, located in Monument Square. Any questions regarding your water and sewer bill can be directed to the Utility Billing Clerk at the Town House, who can be reached at 978-318-3062. We cannot accept payment at the Water and Sewer Division office.
Over time a layer of sediment will buildup in the tank and when high demand is placed on your hot water the sediment becomes stirred up. This situation can typically be remedied by turning down your hot water tank temperature if it is high and flushing out your tank twice a year. Manufacturers suggest doing this once year for general maintenance but twice a year (when you switch your clocks) will keep it nice and clean.
Most residential water service lines are small diameter, underground pipes that carry water from a large diameter water main in the street to your private residence. Concord Public Works is generally responsible for maintaining the section of your service between the water main and your private property. The homeowner is generally responsible for maintaining the section of the service within the private property.
If you know lead is present in your drinking water (from a water test), if you have pipes or plumbing fixtures that contain lead, or if you don’t know the material type, you can take steps to minimize potential lead exposure until all sources of lead have been removed.
Most faucets purchased prior to 1997 were constructed of brass or chrome-plated brass, which contain up to 8 percent lead (the main metals in brass are copper and zinc). Water sitting for several hours or overnight in a brass faucet can leach lead from the brass faucet interior which may produce high lead levels in the first draw of drinking water. Later regulations mandated that most faucets purchased after 1997 contain less lead than previously used thereby reducing the possible leaching of lead. However, the most recent legislation, called “Get the Lead Out,” mandates that after January 4, 2014, all faucets purchased will contain no more than a weighted average of 0.25 percent lead in relation to wetted surface.
Some faucet manufactures produce plastic faucets that have virtually zero lead. Other manufactures are substituting other metals for the lead in the brass, inserting copper tubes inside the brass faucets, or applying special coatings on the inside of the faucets in order to minimize or eliminate lead leaching. With the recent legislation, more and more faucet manufacturers are advertising faucets that adhere to the new “lead-free” definition allowing a maximum of 0.25 percent lead.
In extreme cases, older faucets can contribute up to one-third of the lead in water that has been sitting in the pipes for several hours, with the remainder coming from other plumbing such as pre-1988 lead solder joints in copper pipes or a lead service line. Residents who let the water run at the tap in the morning for one minute and use cold water for cooking should have little concern with respect to lead in the drinking water. If residents are still concerned, they can have their water tested.
Federal and State lead regulations do not cover any pipes, pipe fittings, plumbing fittings, or fixtures, that are used exclusively for nonpotable services like manufacturing, industrial processing, irrigation, outdoor watering (hoses), or other uses where the water is not anticipated to be used for human consumption. This includes toilets, bidets, urinals, fill valves, flushometer valves, tub fillers, shower valves, service saddles, or water distribution main gate valves that are two inches in diameter or larger.
Be sure that only valves and filters intended for drinking water supply are used in any home plumbing project.
Service line material information is based upon historical permit or service installation records, water main installation/replacement records, meter records, and/or misc. maintenance, repair and replacement work. If existing records are incomplete or unclear, a visible inspection of the water service entering your home can provide valuable information. As the effort to investigate this information can take appreciable time, Concord staff have already begun While much effort Division staff have begun If this information is inconclusive, it may be necessary to expose the service using conventional excavation/digging equipment.
Concord water is willing to share any information we have regarding this service. Yes, just give us a call at 978-318-3250. If you are leaving a message please make sure to leave your name, number and the location of interest so we can respond (and log the inquiry) accordingly.
Yes, just give us a call at 978-318-3250 and we will walk you through all the details on sample collection, trusted labs and available programs.
You can use any Massachusetts Certified Drinking Water Laboratory http://www.mass.gov/eea/agencies/massdep/water/drinking/certified-laboratories.html
We recommend you use a certified lab that processes water samples from both private (homeowners/commercial) and municipal customers as we have found some that take only private customers provide misleading information and upsell testing.
The composition of water service lines are generally related to the age of the service. Prior to the mid 1930’s, typical residential water service lines were made of lead or galvanized iron pipe. In the mid 1930’s the industry began changing over to using copper service lines. Beginning in the 1990’s, the industry began to use plastic or high density polyethylene.
Read Concord’s Water's most recent annual water quality report at www.concordma.gov.wqreport.pdf, which provides an general overview of drinking water quality in Concord, from the source to your tap.
Lead is not present in measurable quantities at the Town’s source of supplies. Lead that is detected is introduced into your tap water through corrosion of a lead service lines or building plumbing materials. In Concord prior to the 1930’s, lead was used for exterior plumbing connections and can be found in older buildings. If the service line at your property is made of lead, you are encouraged to replace it or take steps to reduce the risk from lead in drinking water.
The National Sanitation Foundation (NSF) advises that filters certified as NSF-053 effectively reduce lead in water. The NSF certification logo should be visible on the packaging. These filters can remove up to 99 per cent of the lead.
In response to recent regulatory changes, faucet manufacturers have decreased or eliminated the use of lead in residential kitchen faucets, bathroom faucets, bar faucets, drinking fountains, and icemakers. Since January 4, 2014, all faucets must be produced with no more than a weighted average of 0.25 percent lead with respect to the wetted surface. The national standard for certifying plumbing fixtures "lead free" status is determined by the National Sanitary Foundation (NSF) - the standard is International Standard 61-Section 9. New faucets meeting the NSF 61 standard will have NSF 61/9 stamped on the new faucet’s cardboard box. For more information on lead-free fixtures including catalogs and website directories, contact NSF at 1-800-NSF-MARK or www.nsf.org.
For treated drinking water, the U.S. Public Health Service and the U.S. Centers for Disease Control and Prevention (CDC) recommend between 0.7 and 1.2 parts fluoride per million parts of water. Concord water strives to achieve and maintain a fluoride concentration of 1.0 parts per million (ppm) in its municipal drinking water supply. For more information on the content of Concord water, please
A number of factors impact which sources are being run at any given time, such as time of year, system demand, pump station maintenance/upgrades, and source quality. Water from each individual source is treated to the same overall standards, so regardless of which well(s) may be running at any given time, the water is clean and safe for consumption.

During this time, we ask all customers to be mindful of their outdoor water use needs and activities by adopting best management practices. These efforts, if successful, will help preserve our natural water resources and will extend the period of time before more serious restrictions may need to be imposed. Concord’s Advisory level corresponds generally to ‘Normal’ or ‘Advisory’ levels as defined within the Massachusetts Drought Management Plan.
New lawns and plantings which require watering beyond what is allowed under the current State of Water Conservation require a Water Use Restriction Variance. Water Use Restriction Variances are issued at the discretion of the Concord Public Works Director and can be obtained online at www.concordma.gov/watervariance . Water Use Restriction Variances will not be issued during a Lawn Watering Ban in order to encourage residents to plant new lawns in the spring when water is more plentiful.
