Water Utility Resilience Program

This program supports local drinking water and wastewater utilities in strengthening their resilience and prepare for emergencies and the development of statewide mapping initiatives.

Overview

The Water Utility Resilience Program (WURP) supports local drinking water and wastewater utilities in their efforts to prepare for climate change. The Program is a collaborative effort across MassDEP to improve the availability of map products from water utilities. WURP provides community public drinking water systems (COM PWSs) and publicly-owned treatment works (POTWs) with technical assistance to develop or update geographic information system (GIS) datasets and critical infrastructure maps. As part of this effort, WURP also develops and maintains statewide service area maps to depict the geographic area served by publicly or privately owned drinking water or sanitary sewer utilities. The utility-level critical infrastructure maps and the statewide service area maps are designed to enhance critical infrastructure resilience planning, asset management planning, and climate change adaptation.

News and Updates

December 2025

MassDEP is pleased to announce data updates to the Estimated Sewer System Service Area Boundaries published via MassGIS. Updates to the dataset include information regarding estimates for parcels served by publicly-owned treatment works (POTWs) and areas of a municipality served by POTWs, as well as improved data quality from increased confirmation of areas served by sanitary sewer services. A summary of enhancements is available. The full dataset including description, metadata, and data are available for download through the MassGIS’s dataset landing page or viewable online via MassMapper. 

This mapping effort began in 2017, as part of the "Enhancing Resilience and Emergency Preparedness of Water Utilities through Improved Mapping.” Through this project, the MassDEP Water Utility Resilience Program (WURP) began to uniformly map drinking water and sewer service areas throughout Massachusetts using information collected from various sources. Along with confirming existing sanitary sewer service area information, the MassDEP WURP Mapping Project collected and verified estimated service area delineations for POTWs and private treatment works (e.g., non-POTWs). All sewer service area delineations are approximate estimates for broad planning purposes and should only be used as a guide. These data are considered estimates because not all properties within a service area are necessarily served by the system, and the system could serve some properties outside the mapped service areas – please contact the relevant system to confirm service. Please review the accompanying metadata for additional details about the dataset development, review, and maintenance process. Questions may be directed to WURP at [e-mail].

Critical Infrastructure GIS Mapping Initiative

“Enhancing Resilience and Emergency Preparedness of Water Utilities through Improved Mapping”

The Water Utility Resiliency Program focuses on the following      .

1. Technical assistance to water utilities: WURP provides free critical infrastructure mapping assistance to public drinking water and wastewater systems. WURP and their consultant work directly with the public drinking water or wastewater system to develop and update their infrastructure maps, which  improves asset management, enhances emergency response, and aids compliance to regulatory requirements. This objective also supports MassDEP with secure access to critical infrastructure mapping information, which strengthens emergency preparedness and resilience planning.
2. State GIS data: WURP develops and maintains statewide datasets made available through MassGIS.
3. Increase data accessibility through the development of data visualization tools and reports.

A full project history and critical infrastructure assistance provided to date is available below.

Enhancing Resilience and Emergency Preparedness of Water Utilities through Improved Mapping: 2016 - 2025

How can the program help my drinking water and/or wastewater utility?

 The Water Utility Resilience Program (WURP) can assist with identifying helpful and practical resiliency resources, finding opportunities for local and regional partnerships, offering infrastructure mapping and adaptation planning assistance, and coordinating training opportunities.

What specific support can the program provide?

WURP prioritizes technical assistance for publicly-owned drinking water and wastewater utilities based on system vulnerability and infrastructure risks identified through desktop assessments that determine topographic vulnerabilities, emergency response events, regional program recommendations, and utility interest. The most recent offer for technical assistance closed on February 14, 2025. Additional opportunities may be available in the future. WURP can connect water utilities with valuable climate change information and resources.

Estimated Service Area Boundaries Data

Service area data are important resources for visualizing the spatial distribution and boundaries of areas served by public drinking water, publicly-owned treatment works, and facilities with surface or groundwater discharge permits. 

Historically, the Massachusetts Department of Environmental Protection (MassDEP) lacked a consistent method of tracking water and sewer map availability in a standardized format across the Commonwealth. 

Through a collaborative effort between MassDEP's Water Utility Resilience Program (WURP) and Geographic Information Systems (GIS) program, and with support from the MassDEP's Drinking Water Program, Wastewater Permit Programs, WURP began cataloging map products submitted to the Department in 2016. The statewide inventory included a review of historical mapping projects, available online information, and internal MassDEP files, including hand drawings on road atlas maps, blueprints, CAD maps, and GIS data. Beginning in 2017, WURP developed draft service areas maps using the cataloged information. MassDEP staff then contacted each water utility to confirm the boundaries of the areas served. An iterative process has been implemented to ensure the service area boundaries are accurate. This process includes collecting data, verifying estimated service area delineations for systems not previously delineated, maintaining confirmed service areas,  and updating information contained in the datalayers. 

This statewide mapping effort from WURP produced the following datasets:

• MassDEP Estimated Public Water System Service Area Boundaries: This GIS dataset represents approximate service areas for Community (COM) and Non-Transient Non-Community (NTNC) Public Water Systems (PWS) in Massachusetts.
• MassDEP Estimated Sewer System Service Area Boundaries: This GIS dataset represents approximate service areas for sewer systems operated by publicly owned treatment works (POTWs) and surface and groundwater discharge permitted facilities in Massachusetts.

These data can be accessed via MassMapper online or downloaded via the MassGIS WURP Project landing page and the MassGIS data hub.

The estimated service area data were first published via MassGIS in 2024.  Since the initial publication, staff have continued to update and improve the quality of the data. Changes to the data are documented and made available below.

Climate Change Information & Resources

To best identify helpful climate change resources for the water utility sector, WURP actively participates in various agencies’ climate change programs as well regional calls concerning water security and water use. Below are some climate-related programs and resources that the water sector may find useful.

MA Executive Order 569 & the Municipal Vulnerability Preparedness (MVP) Program

In September 2016, the Governor signed EO 569, “Establishing an Integrated Climate Change Strategy for the Commonwealth,” which, among several other actions, requires the state to publish a Climate Adaptation Plan. This plan is currently under development as a combined State Hazard Mitigation and Climate Adaptation Plan, with an anticipated completion date of September 2018. In addition, EO 569 requires the state to establish a framework for each City and Town in the Commonwealth to assess its vulnerability to climate change and extreme weather events, and to identify adaptation options for its assets. The MVP grant program is a direct result of this EO 569 requirement and provides support for cities and towns to begin the process of planning for climate change resiliency and implementing projects.
