Gap III Energy Grant
The Massachusetts Gap Energy Grant Program provides state grant assistance to Municipal and District drinking water and wastewater treatment facilities for installing energy efficiency measures (e.g., variable speed drives; pumping, aeration, and HVAC upgrades etc.) and clean energy generation projects (solar photovoltaic, in-line hydropower, water source heat pumps etc.) at their plants and pumping stations.
MassDEP anticipates releasing our $5 Million Gap Energy Grant Program procurement documents on COMMBUYS in the near future.

Tools & Resources for Treatment Plant Owners and Operators
- US EPA Technical Assistance Webinars: CWA-NPDES Permit Compliance at Small Wastewater Treatment Systems
This webinar series is aimed at improving surface water quality and reducing potential impacts on drinking water by educating permittees on Clean Water Act - National Pollutant Discharge Elimination System permit requirements.
- Pump System Optimization & Assessments: A Management Workshop and Webinar
Presentations and information on Pump System Optimization & Assessments for Municipal Drinking Water and Wastewater Facilities workshop held November 4, 2015.
- Massachusetts Drinking Water & Wastewater Facilities Energy Management Pilot
Results of the first phase of the Massachusetts Energy Management Pilot for Drinking Water and Wastewater Treatment Facilities, designed to reduce municipal and regional treatment plant greenhouse gas emissions and energy use by 20 percent.
- Emergency Planning and Preparedness Tips for WWTP and WTP Operators
This checklist provides operators and key staff members with information and advice on critical items that should be considered and checked to help you gauge your treatment plant's emergency preparedness status.
- TR-16 Guides for the Design of Wastewater Treatment Works
The new Technical Report #16 (TR-16) covers in detail the important elements of wastewater treatment that must be considered in the design of wastewater treatment works. The content, however, has been completely updated to reflect current practices and to include advances in technology, nutrient removal, energy efficiency, and instrumentation. The intended audience includes engineers who design wastewater treatment plants, state regulators who review and approve designs, and municipalities that are soliciting professional design services for wastewater treatment facilities.
- Municipal Compliance Fact Sheet: Wastewater
What municipal officials need to know to ensure that community wastewater systems are operating effectively and properly protecting public health and the environment.

EPA and Massachusetts Water and Energy Utility Resilience Virtual Workshop
Pathway to Resiliency: Preparation, Energy Efficiency, and Renewable Power
October 26, 27, and 28, 9 am – 12 pm ET
The U.S. Environmental Protection Agency (EPA) and the Massachusetts Department of Environmental Protection (DEP) are partnering to offer drinking water and wastewater utilities the opportunity to learn more about becoming less reliant on the electrical grid. Please join EPA and DEP to learn about tools and funding to increase power resilience and to hear from utilities that have successfully reduced their reliance on the grid and more resilient during grid power outages. The no cost, virtual workshop, scheduled as three separate sessions, will kickoff with a tabletop exercise designed to encourage participants to discuss how they would respond to a widespread power outage lasting at least two weeks.
Register for Session 1 on October 26 (Table Top Exercise):
