I/A OWTS stands for Innovative/Alternative Onsite Wastewater Treatment System. These systems use advanced biological processes to remove up to 70% of nitrogen from household wastewater before it reaches the groundwater, far exceeding the performance of traditional cesspools or septic systems. They are required for new construction and major renovations in Suffolk County under Article 6 of the Suffolk County Sanitary Code.

Are there financial incentives to install an I/A OWTS in Suffolk County?

Yes. Through the Suffolk County Septic Improvement Program (SIP), eligible homeowners can receive combined State and County grants of up to $30,000 toward the cost of I/A OWTS installation. Low-interest financing at fixed rates is also available. Rescue Cesspool and Drain helps you determine eligibility and navigate the grant application process.

What maintenance is required for an I/A OWTS system?

I/A OWTS systems require periodic maintenance and inspections — typically annual service contracts — to ensure continued efficiency and compliance with Suffolk County Department of Health Services requirements. Rescue Cesspool and Drain offers ongoing service plans to keep your system running smoothly.

Suffolk County Regulation

Is Your Property Required to Upgrade to I/A OWTS?

The Law Since July 1, 2021

Under Article 6 of the Suffolk County Sanitary Code, all new residential construction in unsewered areas requires I/A OWTS. Major reconstructions, where project costs exceed 50% of the property's market value, also require an upgrade. Adding more than five bedrooms with an expanded footprint triggers it too.

Why Nitrogen Reduction Is Mandatory

Traditional cesspools pass nitrogen directly into groundwater untreated. With 360,000 homes on individual wastewater systems across Suffolk County, nitrogen pollution is the primary cause of algal blooms, beach closures, and shellfish industry losses across Long Island's bays.

I/A OWTS systems actively treat wastewater using biological processes, removing up to 70% of nitrogen before it reaches the groundwater, compared to zero reduction from a conventional cesspool or standard septic system. That's the core reason Suffolk County, the NYSDEC, and the Long Island Nitrogen Action Plan (LINAP) have made these systems the required standard for new construction and major renovation projects.

Up to $30,000 in grants available

Through the Suffolk County Septic Improvement Program (SIP), eligible homeowners can receive combined State and County grants toward the full cost of their I/A OWTS installation. Rescue Cesspool & Drain is a certified installer, we handle the permitting, installation, and can walk you through the grant application from start to finish.

 Trustindex verifies that the original source of the review is Google. Peter and his crew were great. Just bought this house built in 1960 and we had no idea where the cesspool was. Welp they found it. They cleared. They built a better system around it. And taught us new things. Highly recommend.
