Long Island Homeowners Can Now Access Up to $20,000 in Grants for Cesspool and Septic System Upgrades

If you’re a Long Island homeowner with an aging cesspool or septic system, 2025 could be the year you finally make that crucial upgrade without breaking the bank. Thanks to unprecedented federal and state funding initiatives, eligible homeowners can now receive up to $20,000 in grants to replace their outdated systems with advanced nitrogen-reducing technology.

The Grant Opportunity That’s Changing Everything

The New York State Department of Environmental Conservation has received $2.25 million in federal funding through the Bipartisan Infrastructure Law to advance Suffolk and Nassau counties’ septic replacement programs. This is just the beginning – over the course of five years, an anticipated $8 million from the federal program will help support state- and locally-driven water quality improvements.

For Suffolk County residents, homeowners can be eligible for a grant of up to $10,000 to replace failing septic systems with new, nitrogen-reducing Innovative Advanced (IA) septic systems. Nassau County offers even more generous support through their Septic Environmental Program to Improve Cleanliness (S.E.P.T.I.C.), which provides grant funding of up to $20,000 to repair and replace failing septic systems with nitrogen-reducing systems.

Why These Grants Matter for Long Island

The urgency behind these grants stems from a critical environmental issue. The New York State Department of Environmental Conservation has determined that conventional septic systems and cesspools on Long Island are considered failing since they are neither designed, nor capable of removing significant amounts of nitrogen. This nitrogen pollution has serious consequences for our local environment and water quality.

Nitrogen pollution from cesspools and septic systems has been identified as a leading cause of degraded surface water quality on Long Island, contributing to restrictions on shellfishing, toxic algae blooms, and massive fish kills. The problem is particularly acute in Nassau County, where approximately 40,000 residential properties on the North Shore are currently served by cesspools and septic systems.

How the New Technology Works

The nitrogen-reducing systems being promoted through these grants represent a significant technological advancement. The approved nitrogen-reducing technologies use filtration and biological processes to ultimately convert the organic nitrogen found in wastewater into harmless nitrogen gas. These IA OWTS systems have been shown to remove up to 90% of the nitrogen that leads to environmental problems.

To put this in perspective, a conventional septic system releases around 40 pounds of nitrogen per year, which contributes to unhealthy water conditions in the Sound. The enhanced systems have the potential to reduce up to 70 percent of this nitrogen, depending on the specific brand and model.

Eligibility and Application Process

The grant programs prioritize properties based on several factors. Considerations include the property’s location in relation to a waterbody, impacts to groundwater used as drinking water, and the condition of the property owner’s current septic system. As of 2024, there are currently enough County and State funds for 403 grants, with provisional grant acceptance given on a first-come, first-served basis to qualified applicants.

However, these systems do come with ongoing responsibilities. Maintenance agreements typically cost about $300 per year, and proper maintenance helps ensure that these systems continue to remove nitrogen as designed. If you’re considering this upgrade, it’s important to work with experienced professionals who understand both the installation requirements and the ongoing maintenance needs.

The Urgency of Acting Now

With limited funding available and applications processed on a first-come, first-served basis, Long Island homeowners shouldn’t delay in exploring these opportunities. Whether you’re dealing with a failing system that requires immediate attention or simply want to be proactive about environmental responsibility, professional Cesspool Repair Long Island services can help you navigate both the grant application process and the technical requirements for system upgrades.

Looking Ahead

These grant programs represent more than just financial assistance – they’re part of a comprehensive effort to restore Long Island’s water quality for future generations. The projects will protect Long Island’s drinking water supply while also protecting surface waters and associated marine and freshwater fisheries and habitats, with efforts made by New York State during the past several years beginning to reverse decades of declining water quality.

For Long Island homeowners, 2025 presents an unprecedented opportunity to upgrade their wastewater systems with significant financial support. By taking advantage of these grants, you’re not only improving your property value and system reliability but also contributing to the restoration of our region’s precious water resources. The question isn’t whether you should consider this upgrade – it’s whether you can afford to wait any longer.
