Upgrade Your Wastewater Treatment System With Assistance From Suffolk County

In recognition of Long Island’s ongoing water quality crisis, Suffolk County has assertively set the stage for the transition from cesspools and septic tanks to Innovative and Alternative Onsite Wastewater Treatment Systems (I/A OWTS). To make the cost of I/A OWTS systems — with an average total cost of $19,200, contingent on system requirements and site constraints — more affordable for homeowners, Suffolk County has developed the Reclaim Our Water Septic Improvement Program (SIP).

Through the SIP program, homeowners who decide to replace their cesspool or septic system with the new technologies may 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 these grants, homeowners in Southampton and East Hampton Towns can qualify for $15,000 to $20,000 in rebate funding, which often covers the entire cost of system upgrade when combined with the County/State grant funding. If additional funding is necessary, homeowners can apply to finance up to $10,000 of the remaining cost via a low interest septic replacement loan through CDCLI. These loans are payable over 15 years at a low 3% fixed interest rate.
