Suffolk County has launched a streamlined application portal combining county and state grant programs for homeowners replacing cesspools or conventional septic systems with nitrogen-reducing systems.
Suffolk County homeowners may be eligible for up to $45,000 in combined county and New York State assistance to replace outdated cesspools or septic systems.
County Executive Ed Romaine announced the new streamlined application system on Aug. 3. The portal is designed to let residents apply for both county and state septic-upgrade funding through one process.
The county’s Septic Improvement Program can provide qualifying homeowners with up to $20,000. New York State’s Septic System Replacement Program can provide additional assistance covering up to 75% of eligible costs, capped at $25,000.
Together, that creates a maximum potential benefit of $45,000 per qualifying property.
Suffolk County says nearly 70% of homes rely on cesspools or septic systems. County officials argue that older systems are a major source of nitrogen pollution affecting groundwater, bays and other local waterways.
The county portion of the program is funded through the voter-approved one-eighth-cent sales tax dedicated to water-quality improvements.
The $45,000 figure is a maximum, not a guaranteed payment. Eligibility depends on the property, qualifying project costs and program requirements. Some costs, including certain engineering, landscaping and maintenance expenses, may remain the homeowner’s responsibility.
Residents can review eligibility requirements and apply through Suffolk County’s official septic-grant program.
