The Community Energy Challenge: Step by Step
EPA is challenging all New England communities to save money and reduce air pollution by assessing their energy use, taking action to improve energy efficiency, and seeking out renewable energy choices. EPA will provide technical assistance to every community that chooses to Take the Challenge! (2 pp, 58 K, MSWORD)
Step 1. Take the Pledge. Agree to assess energy use in your community's schools, municipal buildings or wastewater facilities. Set a target for reductions (at least 10% lower than your baseline) in energy use intensity (energy use per square foot). The timeframe for reductions is up to participants. Submit the commitment letter (2 pp, 58 K, MSWORD).
Step 2. Assess energy use. Allow the ENERGY STAR Portfolio Manager tool to help your municipality take control of energy consumption in your municipality. Track energy use per square foot, costs, greenhouse gas emissions. Log onto the ENERGY STAR Web site to assess your buildings with the help of the free ENERGY STAR Portfolio Manager tool. Contact us (see below) with questions. Be sure to take free, online webinars to learn how to use Portfolio Manager and more.
Step 3. Understand opportunities for efficiency. Challenge participants can use ENERGY STAR resources like the Building Upgrade Manual and work with organizations across the region to identify opportunities for energy efficiency and renewables. These groups include:
These organizations can help you increase energy efficiency and promote renewable energy use within municipal operations and throughout your community as well. For examples of using ENERGY STAR Portfolio Manager software to develop an Energy Management Plan for your municipality visit Nashua Regional Planning Commission.
Step 4. Recognize successes.

Energy & Water Infrastructure
EPA maintains a national webpage devoted to this topic.
Drinking water and wastewater systems account for approximately 3-4 percent of energy use in the United States, adding over 45 million tons of greenhouse gases annually. Further, drinking water and wastewater plants are typically the largest energy consumers of municipal governments, accounting for 30-40 percent of total energy consumed. Energy as a percent of operating costs for drinking water systems can also reach as high as 40 percent and is expected to increase 20 percent in the next 15 years due to population growth and tightening drinking water regulations.
The good news? Studies estimate potential savings of 15-30 percent that are "readily achievable" in water and wastewater plants, with substantial financial returns in the thousands of dollars and within payback periods of only a few months to a few years.
Determining Energy Usage - Provides tools and guidance for water industry professionals.
Cutting Energy Usage & Costs - Provides information on how to develop an overall energy management program based on EPA's Energy Management Guidebook for Wastewater and Water Utilities as well as system best practices and strategies for making your utility more energy-efficient.
Renewable Energy Options - Provides guidance documents and materials to help water and wastewater facilities implement on-site renewable energy production and/or purchase green energy.
Designing RFPs and Contracts that Promote Energy Improvements at Contract Operated Drinking Water and Wastewater Utilities - Contract language between system owners and contracted operators can impede or encourage improvements in energy management. The goal of this document is to encourage communication on the issue of energy efficiency and renewable energy between municipalities and contract operators.
Paying for Energy Efficiency
EPA's Clean Water and Drinking Water State Revolving Funds (SRF) serve as an important source of financing for drinking water and wastewater infrastructure. Upgrades to decrease energy use are eligible for funding from these programs.
State Efforts to Promote Energy Efficiency
Some states have programs to assist public water systems and wastewater treatment facilities to better manage their energy use.
Maine - EPA, Efficiency Maine and the Maine Department of Environmental Protection (DEP) recently concluded a series of energy management roundtables for water and wastewater facilities in Maine. For more information, contact Gina Snyder (firstname.lastname@example.org, 617-918-1837). Maine wastewater facilities in the Great Bay/Piscataqua River watersheds are also encouraged to attend a similar series underway in New Hampshire. More information is below.
Massachusetts - From 2007-2009, Mass Department of Environmental Protection (DEP) ran a pilot program for energy management in this sector. The results can be found at this link: Energy Management Pilot for Wastewater and Drinking Water Plants. The participating plants, along with several other plants in Massachusetts, received ARRA (stimulus) funding for energy upgrades. A case study about the results of the pilot and the ARRA-funded projects is available at this link (PDF) (8 pp, 988 K).
After the success of the pilot, DEP, the Department of Energy Resources (DOER), Executive Office of Energy and Environmental Affairs (EOEEA), and EPA New England joined forces to create a statewide program with the goal of introducing energy management techniques to all municipally-owned drinking water and wastewater facilities in the Commonwealth. All facilities will receive outreach and training opportunities and may request technical assistance. In addition, a group of "Energy Leaders" selected because of their size or existing work with energy efficiency and/or renewable energy has been invited to meet. This group will receive additional training and technical assistance, with the goal of increasing the number of facilities in the state that are "Zero Net Energy," meaning they produce as much energy over a year as they consume. A case study on Zero Net Energy facilities is available at this link (PDF) (2 pp, 175 K). For more information, contact Mike DiBara (Michael.Dibara@state.ma.us) at MA DEP or Jason Turgeon (email@example.com, 617-918-1637) at EPA Region 1.
This map (PDF) (1 pg, 188 K) shows the water and wastewater facilities and districts in Massachusetts that are working with MA DEP, MA DOER, and EPA New England to address energy use.
New Hampshire - In conjunction with New Hampshire Department of Environmental Services (NH DES), EPA has recently launched a series of energy management roundtables for wastewater utilities. This series is open to all facilities in New Hampshire but will have a geographical focus in the Great Bay/Piscataqua River watersheds. Facilities in Maine that discharge effluent into these watersheds are also encouraged to attend. For more information or to attend, contact Linda Darveau (firstname.lastname@example.org, 617-918-1718).
Rhode Island - All 19 wastewater facilities in Rhode Island are working to increase their energy efficiency and use of renewable energy under a State Innovations Grant provided by EPA. For more information, contact Gina Snyder (email@example.com).
As energy costs steadily increased in the 1990's the Lowell Regional Wastewater Utility (LRWWU) began focusing on energy efficiency, tracking energy costs and cost effective process improvements. As shown in the Energy Use Reduction Chart, since 1996 the facility has decreased energy use by over 35% through investments in high efficiency equipment and adopting an approach that makes energy efficiency a priority.
Some of the key areas that have made the LRWWU energy program so successful include:
- Making a commitment to incorporating energy efficiency in system designs and operations.
- Creation of an energy management team within the organization to review energy savings opportunities.
- Tracking energy use and costs on a regular basis.
- Performing periodic energy audits.
- Setting energy saving goals and monitoring results
- Taking full advantage of utility energy incentive programs to provide evaluations and support for project implementation.
- Making use of on-site emergency generators to participate in demand response programs.
As the LRWWU continues to refine their program, they have embraced the "Plan-Do-Check-Act" approach in the EPA's new Energy Management Guidebook for Water and Wastewater Utilities. The utility is currently pursuing new energy-related projects including more efficient blowers, green roofs on all buildings, solar panels for electricity, and solar heat for some buildings.

Narragansett Bay Commission, Rhode Island
The Narragansett Bay Commission (NBC) operates Rhode Island’s two largest wastewater treatment facilities, providing wastewater collection and treatment for ten cities and towns including the City of Providence. The two facilities, which receive both wastewater and stormwater flow, use a combined total of 27,000,000 kWh per year. For years, the NBC has pursued an active strategy of energy management planning to reduce energy costs and associated effects on the environment. In 2008, the Commission received an EPA State Innovations Grant to work on Energy Management Planning with all 19 wastewater treatment facilities in the state.
Using the “Plan-Do-Check-Act” principles in EPA's Ensuring a Sustainable Future: An Energy Management Guidebook for Wastewater and Water Utilities (PDF) (113 pp, 1.2 MB) and the ENERGY STAR Portfolio Manager tool as a basis for their work, the NBC developed an energy management plan for its own facilities that included audits, operational changes, energy efficient equipment purchases, and renewable energy projects at both of its facilities.
This chart shows the distribution of total electrical cost for one of the two treatment facilities.
The Commission put together an Energy Team that included facility superintendents and managers, engineers, electricians, the finance manager, contractors from the local electric and gas utility, and students from the University of Rhode Island. The Energy Team developed an energy policy and baseline reports, and incorporated audit findings to develop a set of targets and a prioritized list of projects that are expected to reduce the facility's grid purchased electricity use by 22%.

This table shows the energy efficiency and renewable projects that the Narragansett Bay Commission is planning on implementing in 2012 at its two facilities.
The City of Saco, Maine, operates a small wastewater treatment plant with an average daily flow of 2.2 million gallons per day. Although conventional wisdom holds that smaller facilities are inherently less efficient than larger facilities due to economies of scale, the Saco wastewater facility has proven to be the exception to the rule. The facility, which pursues a strategy of continuous improvement and has participated in many of EPA New England’s trainings on Energy Management Planning, consistently scores in the top 5% of plants of its size for energy efficiency as rated by the ENERGY STAR Portfolio Manager tool, and achieves results that rival many of its larger counterparts.
Over the years, the facility has tweaked its operations to be as efficient as possible and has always worked to choose the most efficient equipment when making upgrades. In addition, the facility has pioneered the use of cost-effective solar heating and geothermal heating using plant effluent as a heat source, virtually eliminating its use of imported fuel oil for building heat and saving thousands of dollars per heating season.
This chart shows the 88% reduction in heating oil use at the Saco WastewaterTreatment Plant from the 2004-2005 heating season through the 2010-2011 heating season.
This aerial photo shows the many energy efficient and renewable energy upgrades that have been implemented at the Saco Wastewater Treatment Plant in the last decade.
This section of the site houses information on renewable energy including biomass, geothermal, landfill gas, ocean, solar and wind.
Renewable energy is energy that is produced from renewable sources such as the sun, wind, ocean, plants or waste. While some types of renewable energy have fewer environmental impacts than others, it is generally acknowledged that producing energy from renewable sources has fewer adverse environmental impacts than energy from fossil fuels. Please see the links below for information on common renewable sources, siting and development issues, funding, and policies and regulations.

- Siting renewables on contaminated land
EPA is encouraging the development of renewable energy by identifying currently and formerly contaminated lands and mining sites that present opportunities for renewable energy development. Using these cleaned-up areas to site renewable energy facilities is one potential way to help meet the growing national demand for renewable energy while lessening pressure on greenspace and providing economically viable and socially beneficial futures for sites that are currently under-used or vacant.
- An overview of EPA's Renewable Energy Initiative on Contaminated Lands (PDF) (16 pp, 122 K)
The goal of the 25x'25 program is for the United States to get 25 percent of its energy from renewable resources like wind, solar, and biofuels by the year 2025. In New England, the governors of New Hampshire and Vermont have officially endorsed the 25x'25 vision.
- Landfill Methane Outreach Program (LMOP) is a voluntary assistance program through the US EPA that helps to reduce methane emissions from landfills by encouraging the recovery and beneficial use of landfill gas (LFG) as an energy resource. LFG contains methane, a potent greenhouse gas that can be captured and used to fuel power plants, manufacturing facilities, vehicles, homes, and more. By joining LMOP, companies, state agencies, organizations, landfills, and communities gain access to a vast network of industry experts and practitioners, as well as to various technical and marketing resources that can help with LFG energy project development.
