To further CDLI’s mission of increasing investment in neighborhoods, protecting the assets of homeowners, and protecting the environment, a low-interest rate loan product is now available to assist with the installation of a new septic system in homes with failing cesspools!

To reverse decades of damaging nitrogen pollution of ground and surface waters on Long Island, this new loan from CDLI is made available to assist with the cost of replacing outdated and failing septic systems with state-of-the-art nitrogen-reducing systems or a lesser-cost hybrid system. CDLI will make its low-interest loan available if the homeowner is in need of additional funds to cover the costs of installing the new system. Loan application fees and closing costs do apply to this product. Loan amounts cannot exceed $10,000.


Available for homeowners anywhere on Long Island, near water, or further away in the center. Primarily, those homeowners who do not qualify for the Suffolk County program for Septic Replacement System. This loan product is not available for homeowners who are looking to replace a conventional cesspool with another conventional cesspool system.
