Welcome to the Watershed!

The Catskill Watershed Corporation (CWC) is a locally based, locally staffed nonprofit helping West of Hudson Watershed communities and businesses thrive while protecting the source of one of the world’s largest unfiltered water supplies.

Serving 41 towns and 8 villages across 5 counties in NYC’s West of Hudson Watershed, CWC provides grants and resources that support #WatershedLiving.

Are You Located in the Watershed?

The CWC Septic Repair & Replacement Program is a voluntary grant program for eligible homeowners in the West-of-Hudson NYC Watershed, including parts of Delaware, Greene, Ulster, Schoharie, and Sullivan counties.

Program Eligibility:
1) Property must be located in the West of Hudson Watershed.
Use the map to determine if your address qualifies
2) Your house and system must be 20 years or older
3) Your septic system must be designed for less than 1,000 gallons per day
4) Your septic system must be failing or likely to fail as determined by a licensed septic contractor.

If your property meets the above requirements, you can submit a Septic Program Application to get started.

If you need help determining your septic system’s health, you can schedule a pump-out or inspection with a local licensed contractor.

Note: Catskill Watershed Corporation infrastructure programs such as Septic are only available within the Watershed, however some CWC programs are available countywide.
