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.


The project is currently finalizing designs for the resilience upgrades and plans to start implementation in 2024 to protect 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

Analysis Project

Town of Seabrook Wastewater Treatment Facility Climate Resilience Assessment

In order to inform long-term planning and ensure public health and safety, the WWTF Climate Resilience Assessment project will help 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. The Town has released a video and online survey form ( to hear your thoughts, concerns, and questions regarding the project. 

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.
