Septic System Replacement Fund

Homeowners: Reach out to your local program contact if you have questions about whether your property is eligible for grant funding. 

Governor Hochul has made $30 million available for Round 4 of the program.

The Septic System Replacement Fund Program focuses on improving water quality by providing funds to counties to help homeowners replace cesspools and septic systems that are adversely impacting designated waterbodies. Participating counties, as outlined below, provide grants to reimburse property owners for up to 50% of the costs (up to a maximum of $10,000) of their eligible septic system projects. The list of participating counties and their designated waterbodies was updated in April 2024.

The state Department of Environmental Conservation and the Department of Health determined priority geographic areas in which property owners are eligible to participate based on the following factors:

• Presence of a sole-source aquifer used for drinking water.
• Known water quality impairment linked to failing septic systems and the ability for septic system upgrades to mitigate water quality impairments.
• Waterbody Inventory/Priority Waterbodies List (WI/PWL) segments that are listed as impaired or stressed for nutrients from septic systems.
• WI/PWL segments that have a public water supply intake located within the WI/PWL segment.
• Waterbodies that are Class A, AA, A-S, AA-S according to the WI/PWL segment.
• Forest Preserve waterbodies.

DEC and DOH will re-evaluate priority waterbodies in future rounds of funding.

Participating counties are responsible for reviewing and evaluating the applications and determine financial assistance awards based on the program criteria. The following considerations are made: property’s location in relation to a waterbody, impacts to groundwater used as drinking water, and the condition of the property owner’s current septic system. After evaluating the applications and making the funding decisions, participating counties notify the property owners of their grant awards by sending them award letters.

Please reach out to your local program contact if you have questions about whether your property is eligible for grant funding.

I would like to apply for the program.

The program is administered by participating counties and each county has a Local Program Contact who can help determine eligibility and next steps for the program. Please refer to the Participating Counties section and find your county’s Local Program Contact and reach out to them.

My county is not listed on the eligible county list, am I eligible?

If your county is not listed in the Participating Counties section then your county is not eligible for the program. However, you may want to reach out to your local County Health or Planning Department to see what other programs the county may have to assist you.

I do not see my waterbody listed as one of the Eligible Waterbodies, can it be added to the program?

The list of eligible waterbodies is final. The legislation creating the program focused on improving water quality in those waterbodies that have documented impairments from septic system pollution. To meet the legislative intent of the program, the New York State Department of Environmental Conservation developed screening criteria that focused on documented water quality impairments and potential for septic replacement to improve water quality.

I live in one of the five NYC Boroughs, is my property eligible for the program?

New York City is continuing to build out the sewer systems in their jurisdiction, therefore none of the five Boroughs (Bronx, Brooklyn, Manhattan, Queens, or Staten Island) are eligible for the State Septic Replacement Program. Sewering is the best solution to improve water quality. People with properties on septic systems or are considering installation of septic systems are encouraged to reach out to New York City Department Environmental Protection to see what options are available. Below is the NYCDEP link for more information.
