Nassau County has initiated a septic system replacement program for residents, small businesses and non profits - Septic Environmental Program to Improve Cleanliness (SEPTIC). The SEPTIC program will provide grant funding to eligible recipients to replace a conventional or failing septic system with an innovative and alternative onsite wastewater treatment system.


Nassau County is offering grants up to $20,000, for homeowners or small businesses to install state-of-the-art nitrogen reducing septic systems.

Maintaining your Septic System


Making sure your I/A system is properly maintained will save you time and money while also allowing the system to sufficiently reduce the harmful nitrogen from your wastewater.


Most of these tips and tricks found in our Do's and Dont's for your I/A Septic System flyer apply to conventional systems as well, so caring from this system is not too different from what you're used to.

Do Not Flush "Flushable" Wipes


Maintaining your septic system starts with not flushing products that hurt your system. "Flushable" wipes and baby wipes can cause blockage inside your pipes or system.

Chemical additives marked to unclog drains, break up oil and greese may also contain acids, solvents, hydrogen peroxide or strong caustic agents. Overtime, excessive use of antibacterial products like wipes can kill off the beneficial bacteria that helps the system operate.
