Nitrogen Reducing Septic Systems

Certified Maintenance Providers for Suffolk County Approved I/A OWTS

Nitrogen Reducing Septic Systems (I/A OWTS)

Nitrogen pollution from cesspools and septic systems has been identified as the largest single cause of degraded water quality contributing to beach closures, restrictions on shell fishing, toxic algae blooms, and massive fish kills. A conventional onsite septic system was never designed to remove nitrogen. The average residential septic system discharges approximately 40 pounds of nitrogen per year. For homeowners close to surface waters in Suffolk County nitrogen can rapidly reach surface waters where it contributes to the degradation of our marshes, bays, and beaches. Even inland, nitrogen from septic systems will eventually reach the groundwater and surface waters.

Thousands of parcels are currently served by polluting cesspools and septic systems, but will never connect to a sewer system. Reversing the degradation of water quality will depend on the replacement of existing systems with new, individual Innovative and Alternative Onsite Wastewater Treatment Systems (I/A OWTS). This is why the installation of a new nitrogen reducing septic system is important to the health and safety of communities in the Hamptons, Montauk and throughout the East End of Long Island.

Suffolk County: Reclaim Our Water:

Over the past several years, Suffolk County has assertively set the stage for the transition to the use of these new systems. To make the cost of I/A systems that remove nitrogen to protect water quality more affordable for homeowners, Suffolk County has developed the Septic Improvement Program. Under the Reclaim Our Water Septic Improvement Program, homeowners who decide to replace their cesspool or septic system with the new technologies will be eligible for a grant of up to $30,000 from Suffolk County and New York State to offset the cost of one of the new systems. In addition to the grant, homeowners can qualify to finance the remaining cost of the systems over 15 years at a low 3% fixed interest rate. The loan program will be administered by Community Development Corporation of Long Island Funding Corp, with financial support from Bridgehampton National Bank, in the amount $1 million and financial commitments from several philanthropic foundations.

Wastewater Works Inc. Distributor of Hydro-Action Industries Wastewater Treatment System

Hydro-Action is an onsite wastewater treatment unit manufacturer with over 25 years of industry experience. Founded in 1988 and relocated to Indiana in 2002, our technology utilizes an activated sludge treatment process, which constantly infuses oxygen to wastewater where aerobic bacteria metabolize the waste. Then it separates in a clarification chamber without the use of media filters, carbon additives, or expensive, high maintenance technologies. We offer our products in a three-tank combination as a single unit: pretreatment, aerobic treatment, and pump tank design as the “Set-N-Go” unit.
