Nitrogen Reducing Septic Systems

Nitrogen Reducing Septic Systems Importance

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 shellfishing, 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). For more information about these septic services, please contact us today. You can also give us a call at (631) 267-7515.

Suffolk County: Reclaim Our Water:

Suffolk County Septic Improvement Program Overview

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.

Town of East Hampton’s Website:

Of the approximately 19,400 developed parcels in the Town of East Hampton, more than 12,500 parcels are using antiquated cesspools and 6,700 use traditional leach field systems to treat wastewater; neither of which were designed to treat for nitrogen removal. Additionally, 6,330 developed parcels, or 32% of the total, are located in the Water Protection District; a critical environmental area. With the passage of the local law extending the Community Preservation Fund (CPF) and expanding its use to include Water Quality Improvement Projects, the Town has access to funding to incentivize the voluntary upgrade of standard sanitary systems to Low-Nitrogen Sanitary Systems.

Based on a 10 year average of CPF revenue (2005-2015), approximately $4,600,000 will available annually for water quality improvement projects.  Over the life of the CPF WQIP, approximately $152,000,000 will be available for water quality improvement projects.  This funding would allow the Town of East Hampton to make significant improvements to water quality using a targeted approach in areas of concern.

Breakdown of Available Funding 

  • Up to $20,000 if your property is located within the Water Protection District or you qualify for affordable housing
  • Up to $15,000 if your property is outside of the Water Protection District
