Advanced I/A (Nitrogen-Reducing) Septic Systems for Long Island

Discount Cesspool & Drain installs and maintains I/A (Innovative/Alternative) septic systems across Suffolk County, Nassau County, and Long Island. These advanced, nitrogen-reducing systems are the modern standard for protecting our groundwater, bays, and drinking water, and they are increasingly required for new construction and many system replacements across the region.

What Is an I/A Nitrogen-Reducing Septic System?

Traditional cesspools and septic systems do little to remove nitrogen from wastewater, and that nitrogen seeps into Long Island’s aquifer and surface waters, fueling algae blooms and degrading water quality. An I/A system adds an advanced treatment unit that actively breaks down and removes a large portion of that nitrogen before the water returns to the ground. The result is a cleaner, more environmentally responsible system that meets Suffolk County’s latest wastewater standards.

Grants and Rebates May Be Available

Suffolk County’s septic improvement program offers grants and rebates that can significantly offset the cost of upgrading to an approved I/A system. We are familiar with the program and can help you understand what your property may qualify for, then guide you through the application paperwork so the process is as simple as possible.

Installation by Approved Professionals

I/A systems must be designed and installed by professionals approved by Suffolk County, and Discount Cesspool & Drain handles the full process: site evaluation, system design, permits, removal of the old system, installation of the treatment unit and leaching components, and final inspection. We make a complex upgrade straightforward for homeowners and businesses across Long Island.

Ongoing I/A Maintenance

Unlike a conventional system, an I/A system requires regular maintenance and monitoring to run properly and stay in compliance. We provide the scheduled service, inspections, and reporting your I/A system needs, so you never have to worry about a missed visit or a lapse in compliance.
