The New Hampshire Department of Environmental Services (NHDES) Nonpoint Source Management Program is seeking to hire a consultant to assist with data collection for the United States Environmental Protection Agency (EPA) 2022 Clean Watersheds Needs Survey (CWNS) for New Hampshire. The full RFP document is now posted on the New Hampshire Department of Administrative Services website:

NHDES manages the Clean Water State Revolving Fund (CWSRF) and EPA Section 319 Clean Water Act (CWA) loan and grant programs respectively, which provide funding for wastewater and stormwater infrastructure, planning, and nonpoint source management projects. To accomplish the required CWNS work, NHDES seeks to enter into a contractual agreement with a qualified consultant to perform the scope of work from approximately June 1, 2022, through March 31, 2023.

Data will be entered into the CWNS database.

NOTE: A New Hampshire State-specific CWNS Approach Presentation (virtual) will be  hosted by the NHDES NPS Management Program staff on February 24th t 9:00 AM. Attendance is strongly encouraged for interested firms to learn more about the specific CWNS approach for New Hampshire relative to stormwater and Nonpoint Source Pollution.
