Seabrook Wastewater Facility
Resiliency Opportunities
Town of Seabrook Wastewater Treatment Facility Climate Resilience Designs
Seabrook’s Wastewater Treatment Facility (WWTF), supporting roadway, and pump stations are vulnerable to climate impacts such as sea level rise and coastal storm surge. Located on Wright’s Island, the aging WWTF collects and treats residential, commercial, and industrial wastewater from most of the town. Any disruptions to WWTF operation due to flooding from sea-level rise and storm surge could result in significant public health risks, disrupt business activities, and potentially pollute groundwater and our oceanfront areas. The Town is proactively planning and preparing the facility for flooding now, before it causes damage or disruption.
PROJECT TIMELINE:

The design of upgrades is complete, and construction will start in 2026 the WWTF and treatment functions from future storm surges, sea level rise, or flooding. Thanks to funding from ARPA and a state of New Hampshire Grant Program, the Town can implement adaptation strategies for the facility right away
Implementation of Upgrades:
- Funding had been secured for both design and construction
- Design Funding : HUD CPF Grant
- Construction Funding: HUD CPF Grant and ARPA CFRING grant
- The Town has created a fact sheet to share key information about the project, click HERE
- Additional funding through HUD CPF Program required an enviromental review, which concluded that no significant impacts are expected from this project.

Analysis Project
Town of Seabrook Wastewater Treatment Facility Climate Resilience Assessment
Weston and Sampson completed the Climate Resilience Assessment, which indenified flooding risks for the WWTF and Route 286 Pump Station. The current project includes recommendations from that assessment. In order to inform long-term planning and ensure public health and safety, the WWTF Climate Resilience Assessment project helped the Town:
-Better understand specific climate impacts to the WWTF
-Identify potential adaptation options for improving the resilience of the WWTF
-Inform the public of project results
Preparing for the long-term impacts of climate change will be critical for the future of our community. Through the Wastewater Treatment Facility (WWTF) resiliency planning process, we want to ensure you are informed about the decisions the Town is making to safeguard this critical community asset.
This project was funded, in part, by NOAA’s Office for Coastal Management under the Coastal Zone Management Act in conjunction with the New Hampshire Department of Environmental Services Coastal Program. The Town has contracted Weston & Sampson, an interdisciplinary design and engineering consultancy, to support this project.
