Septic Systems

Septic systems are used to treat wastewater from homes and small businesses—primarily in rural and suburban areas—that aren’t served by sewer systems and treatment plants. In a properly functioning septic system, pollutant concentrations found in raw sewage are reduced through biological processes that occur in a septic tank, where solid materials settle out and the remaining liquid passes through. Upon leaving the septic tank, the liquid is dispersed through a soil absorption field where further treatment takes place. Very old and/or failing septic systems threaten both groundwater and surface water by releasing untreated or ineffectively treated wastewater into the ground or, even worse, directly into a watercourse.

DEP partners with the New York State Environmental Facilities Corporation (EFC) in the East of Hudson area and Catskill Watershed Corporation (CWC) in the West of Hudson area to implement a series of programs designed to help protect water quality from septic system contamination. EFC is a is a public benefit corporation which provides financial and technical assistance primarily for water quality projects. The CWC is a regional not-for-profit corporation established pursuant to the 1997 Watershed Agreement to administer water quality protection and economic development programs in the Catskill/Delaware (West of Hudson) Watershed.


Septic System Rehabilitation and Replacement Program (West of Hudson)

Since 1997, DEP has committed over $100 million in funding for the Septic System Rehabilitation and Replacement Program administered by the CWC. Program funds are used to repair or replace septic systems serving one- or two-family homes in priority areas of the West of Hudson Watershed.

Eligible costs for septic program funding include septic inspections, one-time septic tank pump-outs, replacement or upgrades of failing systems, and education and outreach. CWC staff conduct initial site visits and septic inspections as well as more detailed system inspections where necessary. Septic systems that are found to be failing or substandard and likely to fail are either repaired or replaced. CWC pays 100% of eligible costs for primary residence septic systems and 60% of eligible costs for second home systems.

Through 2017, the CWC Septic Rehabilitation and Replacement Program has funded the repair or replacement of more than 5,300 failing or likely-to-fail septic systems.

For specific information regarding program rules, project eligibility, application forms, and project selection, please contact the CWC at 845-586-1400 or visit www.cwconline.org.


Cluster Septic System Program (West of Hudson)

The CWC administers the $2 million Cluster Septic System Program that funds the planning, design, construction, and operation and maintenance of cluster septic systems in small population centers or hamlets where individual onsite septic systems are not practical because of small lot sizes. Eligible hamlets have failing septic systems in areas characterized by small lots that are in close proximity and located near watercourses.

For specific information regarding program rules, project eligibility, application forms, and project selection, please contact the CWC at 845-586-1400 or visit www.cwconline.org.


Expanded Septic System Program (West of Hudson)

The CWC administers the Expanded Septic System Program that helps pay for the repair or replacement of failed septic systems serving small businesses (those employing 100 or fewer people), not-for-profit organizations, and governmental entities in the West of Hudson Watershed.

For specific information regarding program rules, project eligibility, application forms, and project selection, please contact the CWC at 845-586-1400 or visit www.cwconline.org.


Septic System Maintenance Program (West of Hudson)

The CWC Septic System Maintenance Program is a voluntary reimbursement program intended to reduce the occurrence of septic system failures through regular septic tank pump-outs and system maintenance. DEP has provided $1.5 million in funding for this program that is open to participants in one of the West of Hudson septic repair programs or owners who installed their replaced septic systems after January 1, 1997 and whose septic tanks have not been previously pumped for at least three years.

Proper and routine septic system maintenance is vital for protecting water quality and prolonging the life of the system itself. While the cost of repairing or replacing a septic system can be very expensive, the effort and expense of routine maintenance is minimal. The key to avoiding septic failure is periodic pumping of the septic tank. Without regular pumping, sludge and scum layers become too thick and solid materials can flow from the septic tank into the soil absorption field, clogging the pipes and causing the system to fail.

East of Hudson Septic System Rehabilitation Reimbursement Program (East of Hudson)

DEP partners with the New York State Environmental Facilities Corporation (EFC) to fund and implement the East of Hudson Septic System Rehabilitation Reimbursement Program in five watershed basins in Westchester, Putnam, and Dutchess Counties. The Program reimburses eligible homeowners up to 50% of the costs for repairing or remediating failing septic systems, or to connect their septic systems to an existing sewage collection system (up to 75% in cases of demonstrated financial hardship).

Current Program areas include eligible residential properties in the Kensico, West Branch, Boyd Corners, Croton Falls, and Cross River Reservoir Basins, which includes portions of the Towns of Carmel, Kent, Southeast, East Fishkill, Somers, Bedford, Lewisboro, and Pound Ridge. Pursuant to the 2017 FAD, DEP will be working to expand the Program to include eligible properties in the East Branch, Middle Branch, Bog Brook, and Diverting Reservoir Basins.

To determine eligibility or receive additional information about program rules and restrictions, New York State residents should call the EFC at 1-800-882-9721.
