Yes and this is one of the more valuable things to understand before you hire anyone. The Town of Huntington administers its own component of the Septic Improvement Program, separate from the county and state grants. As a South Huntington homeowner, you’re in the Town of Huntington’s jurisdiction, which means you may be eligible for up to $10,000 from the town, plus an additional $1,000 if your property requires a pressurized shallow drain field.
That town-level grant stacks on top of the Suffolk County SIP program and the expanded New York State program, which as of July 2025 can cover up to 75% of your installation cost, capped at $25,000 from the state. The combined total can reach $45,000 or more depending on your system type and eligibility. The critical detail: your grant certificate must be issued before installation begins. If you’ve already had the work done, you’re not eligible. Call before you commit to anything.
The honest answer is that it depends on what’s there and what’s required. A conventional septic system replacement on Long Island typically runs in the $20,000 to $40,000 range. An I/A OWTS nitrogen-reducing system which Suffolk County increasingly requires for replacements averages around $25,000 before any grant offsets. On the higher end, costs can reach $50,000 depending on lot conditions, system size, and site complexity.
What drives the cost up on Long Island specifically is the combination of soil evaluation requirements, SCDHS permit fees, excavation, the system itself, and post-installation documentation. The perc test alone runs $500 to $1,500. Permits typically cost $200 to $500. None of this is us making up numbers it’s what the process actually involves. The good news for South Huntington homeowners is that the grant programs available through the town, county, and state can offset a substantial portion of those costs, potentially bringing your out-of-pocket number down significantly.
A cesspool is essentially a buried pit that collects raw waste and allows liquid to seep directly into the surrounding soil with no treatment whatsoever. Most of the homes in South Huntington were built with cesspools because that was the standard in the 1950s and 60s they were cheap, simple, and nobody was thinking about groundwater contamination at the time.
A septic system is a more engineered solution. It includes a tank that separates solids from liquids, allows for some bacterial treatment, and then distributes the effluent through a leaching field where further filtration occurs through the soil. An I/A OWTS system takes it a step further, using advanced treatment technology to remove nitrogen before it reaches the groundwater. This distinction matters legally in Suffolk County since July 2019, you can no longer replace a failed cesspool with another cesspool. The replacement must meet modern septic standards, and in many cases, an I/A OWTS system is required.
The actual installation work excavation, system placement, connection, and site cleanup typically takes one to three days once everything is in place. We’ve completed installations in a single day in many cases, which matters if you’re trying to minimize disruption to your property and your schedule.
The longer part of the timeline is the permit process. Before any work can begin, a permit application needs to be filed with the Suffolk County Department of Health Services under Article 6 of the Suffolk County Sanitary Code. That process adds lead time typically a few weeks depending on SCDHS workload and how quickly the site evaluation and soil testing are completed. If you’re applying for grant funding through the Town of Huntington or the county SIP program, that application also needs to be processed and a grant certificate issued before installation starts. The earlier you get the process moving, the sooner you’re on the other side of it.
It depends on your specific situation, and the honest answer is that you need a site assessment before anyone can tell you definitively. Suffolk County’s regulations have tightened significantly since 2019, and the direction has been clear: the county wants nitrogen-reducing I/A OWTS systems wherever possible, and certain triggers new construction, major renovations, and properties in designated nitrogen-sensitive areas can make I/A OWTS a requirement rather than a choice.
For South Huntington homeowners, the practical consideration is that even if a standard septic system technically qualifies for your replacement, an I/A OWTS system is the only installation type that makes you eligible for the full grant stack town, county, and state. Given that the combined grants can reach $45,000, the math often works out in favor of the advanced system even if it carries a higher upfront cost. A site visit and a conversation with us will tell you what your property actually requires and what your grant eligibility looks like before you commit to anything.
The old system doesn’t just get abandoned in place there’s a required process for decommissioning it properly. The cesspool gets pumped out completely, and then it’s either crushed and filled or otherwise rendered inoperable so it can’t continue to leach into the surrounding soil. The abandonment is documented, and that documentation becomes part of the installation record that gets filed with the Suffolk County Department of Health Services.
This step matters for a few reasons. First, it’s required under Suffolk County sanitary code you can’t simply cap an old cesspool and walk away. Second, for South Huntington homeowners pursuing SIP grant funding, proper abandonment of the existing system is one of the eligibility requirements. Third, if you ever sell your home, having clean, complete installation records including the abandonment documentation is something a buyer’s attorney will ask for. We provide those records as part of the job, so you’re not chasing paperwork after the fact.
Hear from Our Customers
South Huntington homes have a median value pushing $637,000. When something goes wrong underground slow drains, a smell in the yard, a wet patch that wasn’t there last spring the stakes aren’t just inconvenience. A failing cesspool can stop a home sale in its tracks, trigger a failed inspection, and cost you far more in delays than the installation itself would have.
Getting a properly installed septic system means you’re no longer sitting on borrowed time. The work gets done, the documentation gets filed with the Suffolk County Department of Health Services, and you have a system that actually meets current code not one that’s been grandfathered in and is quietly getting worse.
For South Huntington homeowners specifically, there’s another layer worth knowing: because your home is in the Town of Huntington, you may be eligible for grant funding from three separate sources simultaneously the town, the county, and the state. That’s real money that can offset a significant portion of the installation cost, but only if you apply before the work begins. More on that below.
We’re a family-owned and operated company based in West Babylon, NY, and we’ve been doing this work on Long Island for over 30 years which means we’ve replaced the same generation of post-war cesspools that still sit under most of South Huntington’s single-family homes. This isn’t new territory for us.
The route between West Babylon and South Huntington runs straight up Route 110 Walt Whitman Road which is the same corridor that defines the eastern edge of your hamlet. When we say we serve South Huntington, we’re not stretching a service area map. We’re a short drive up a road we know well, serving western Suffolk County homeowners the same way we always have.
What you’ll notice when you call is that a real person picks up. We give you a real window. We show up. Our customers have said that by name and in an industry where that’s apparently a differentiator, it says something.
It starts with a site visit. Before any numbers get put on paper, we need to see what’s actually there the existing system, the lot size, the soil conditions, and what the property’s layout allows. South Huntington’s glacially deposited soils are generally permeable, which is part of why cesspools worked here for decades. But permeability also means nitrogen from those same aging systems has been migrating into the groundwater for just as long.
A proper site evaluation informs both the system design and the permit application. Once the assessment is done, you get a written estimate. Not a ballpark over the phone that changes when the crew shows up a written scope with real numbers.
From there, the permit gets filed with the Suffolk County Department of Health Services under Article 6 of the Suffolk County Sanitary Code. This is a required step, and it adds some lead time before installation can begin. If you’re pursuing grant funding through the Town of Huntington’s Septic Improvement Program or the county and state SIP programs, the grant certificate also needs to be in hand before any work starts so the earlier you get moving, the better.
Installation itself typically takes one to three days of active work. The old system gets properly abandoned pumped, documented, and filled and the new system goes in. After installation, we provide the records you’ll need for SCDHS documentation. When it’s done, it’s done right.
Ready to get started?
Since July 2019, Suffolk County has banned cesspool-only replacements. If your South Huntington system needs to come out, it has to be replaced with something that meets modern septic standards at minimum and depending on your property and situation, you may be required to install an I/A OWTS system, which is the nitrogen-reducing advanced treatment technology the county has been pushing hard since 2021.
The reason this matters specifically to South Huntington is the grant stack available to Town of Huntington residents. The town administers its own component of the Septic Improvement Program up to $10,000, with an additional $1,000 available if your lot requires a pressurized shallow drain field. That sits on top of the Suffolk County SIP grant and the expanded New York State program, which as of July 2025 covers up to 75% of installation costs, capped at $25,000 from the state alone. Combined, eligible homeowners can access up to $45,000 or more in grant funding. But the grant certificate must be issued before installation begins this is a hard rule, not a technicality. Homeowners who install first and apply later receive nothing.
We handle residential and commercial installations across both Nassau and Suffolk Counties. Whether you’re replacing a failing 60-year-old cesspool, upgrading to an I/A OWTS system to capture grant funding, or dealing with a system flagged during a home inspection, the scope of work is handled from site assessment through final documentation one company, no hand-offs.
