No and this is one of the most common misconceptions among homeowners in Selden and throughout Suffolk County. As of July 1, 2019, Suffolk County banned straight cesspool-for-cesspool replacements. If your existing system fails or needs to be replaced, the new installation must include at minimum a septic tank preceding the leaching structure. You can no longer simply swap one cesspool for another and call it done.
For homeowners in Selden specifically, there’s an additional layer to be aware of. The Town of Brookhaven has enacted Chapter 78A, a Nitrogen Protection Zone ordinance that may require an Innovative and Alternative Onsite Wastewater Treatment system commonly called an I/A OWTS for certain new construction projects within defined zones. Whether that applies to your specific property depends on the project type and location. This is exactly why permit coordination matters: the rules aren’t one-size-fits-all, and getting it wrong means fines, forced redo work, and a failed inspection. We handle the permit process and know what both Suffolk County and the Town of Brookhaven require before any work begins.
For most residential properties in Selden, a full installation takes anywhere from one to five days, depending on the complexity of the system and the site conditions. A straightforward replacement on a property with accessible soil and a clearly located existing system is usually on the shorter end of that range. More involved jobs where the old cesspool needs to be located first, the lot is tight, or a more complex system type is required can take longer.
The sandy loam soil common in central Suffolk County generally cooperates with excavation, which helps keep timelines reasonable. That said, the permit process adds time before the physical work begins SCDHS permit processing typically runs two to four weeks. So while the actual installation may take only a day or two, the full timeline from first call to a signed-off, live system is usually several weeks when you factor in permitting. The best way to avoid delays is to start the conversation before you’re in a crisis. If you’re in Selden and your system is showing signs of age or stress, getting an estimate now puts you ahead of the timeline rather than scrambling to catch up.
The most common signs are slow drains throughout the house not just one fixture, but multiple along with wet or soggy patches in the yard, a persistent sewage smell near the ground, or gurgling sounds coming from toilets or drains. In some cases, sewage backs up into the lowest fixtures in the home, which is a clear signal that the system has lost its capacity to handle the load.
In Selden, where roughly 90% of the housing stock is between 25 and 80 years old, these symptoms often appear in systems that have simply reached the end of their design life. A cesspool installed in the 1950s or 1960s was built to last 30 to 40 years under reasonable conditions many of those systems are now operating on borrowed time. Heavy rainfall events can also expose an underlying problem that’s been developing quietly; water-saturated soil around an aging cesspool will push symptoms to the surface faster than normal. If you’re seeing any of these signs, the sooner you get an evaluation, the more options you have including time to apply for available grant funding rather than making a rushed decision under emergency conditions.
Yes, and it’s significant. Suffolk County’s Septic Improvement Program offers grant funding for eligible homeowners who install Innovative and Alternative Onsite Wastewater Treatment systems. As of mid-2025, combined State and County grants of up to $45,000 are available for qualifying installations. Nassau County homeowners have access to grants of up to $20,000 through a separate program. These grants are paid directly to the certified installer after final inspection, so you pay only the balance not the full amount upfront.
There are a few important things to know. The funding operates on a first-come, first-served basis, and available grants can run out Nassau County had only 403 grants remaining as of 2024. Waiting until a system fails completely means you’re making a rushed decision under emergency conditions with no time to research grant eligibility or compare contractors. Starting the process while your system is still functional gives you the time to explore your options. Grant payments are also not counted as taxable income under IRS Announcement 2022-26, which is worth knowing when you’re budgeting. A contractor who understands the grant process can walk you through eligibility before you commit to anything.
Excavation is a real part of the job there’s no way around it. Installing a new cesspool system requires breaking ground, removing the old system, and creating the space for the new tank and leaching structure. In Selden’s residential neighborhoods, where homes are on modest lots with mature landscaping and neighbors in close proximity, this is a legitimate concern.
What separates a professional crew from a careless one is how we manage the site during and after the work. We handle backfilling and site restoration as part of the installation the job isn’t done when the system is in the ground, it’s done when the yard is back in reasonable shape. The sandy loam soil common in central Suffolk actually helps here, since it’s easier to work with and restore than clay-heavy soil. That said, heavy equipment will leave some evidence of the work, and it’s realistic to expect some disruption to lawn areas directly over the installation zone. Most homeowners find that with proper grading and a growing season, the yard recovers well. If you have specific concerns about landscaping, driveways, or nearby structures, that’s worth discussing during the estimate so the crew can plan around it.
In Suffolk County, all cesspool installation and service work requires a valid Suffolk County Liquid Waste License issued through Suffolk County Consumer Affairs. This is not optional it’s a legal requirement, and working with an unlicensed contractor exposes you to real risk. If the work isn’t permitted and inspected, it can void your certificate of occupancy, create liability during a home sale, and leave you responsible for bringing everything up to code at your own expense.
The simplest way to verify a contractor is to ask for their license number directly and confirm it through Suffolk County Consumer Affairs. Our license number is LW-63684, and it’s listed on every page of our website not buried in fine print, but front and center. That kind of transparency is a reasonable baseline to expect from any contractor you’re considering. Beyond the license, ask whether they pull permits for the job and coordinate the final SCDHS inspection. A contractor who handles the full process permits, installation, and inspection is protecting you from the most common ways cesspool work goes wrong. If a quote comes in significantly lower than others and the contractor is vague about permits, that’s usually the reason why.
Hear from Our Customers
When a cesspool system fails in Selden, it rarely happens all at once. It starts with slow drains, maybe a wet patch in the yard, or a smell that wasn’t there last summer. By the time most homeowners call, the system has been struggling for a while. Getting a proper installation done doesn’t just fix the immediate problem it removes the ongoing anxiety of wondering when the next issue is coming.
For Selden specifically, this matters more than people realize. Nearly 60% of homes here were built between the 1940s and 1960s, which means a significant share of the cesspool systems in this hamlet are operating well past their intended lifespan. A system installed when the neighborhood was new wasn’t designed for today’s household water usage, today’s Suffolk County regulations, or today’s property values which are now sitting at a median of $633,000 and climbing.
Once a compliant, properly permitted system is in the ground, you’re not just solving a plumbing problem. You’re protecting an asset. Home inspections flag cesspool issues, and in Selden’s active real estate market, a failing system can stall or kill a sale. A new installation that passes final inspection gives you clear documentation, no surprises at closing, and one less thing to worry about whether you’re staying put or eventually selling.
We are a family-owned, fully licensed, insured, and bonded cesspool company based in West Babylon, NY right here in Suffolk County. Our license number LW-63684 is publicly verifiable through Suffolk County Consumer Affairs, and it’s displayed on every page of our website because it matters. In this industry, a contractor who can’t show you their credentials before the truck arrives is a contractor worth skipping.
Our team has been working across Nassau and Suffolk Counties for over 30 years. That kind of experience in central Suffolk means we’ve worked on the same postwar Cape Cods and ranch-style homes that make up most of Selden’s housing stock homes where the cesspool location isn’t always documented, the lot is tight, and the system hasn’t been touched in decades. We know what those jobs look like before we arrive.
Selden sits in the Town of Brookhaven, which adds a layer of local regulatory complexity on top of Suffolk County’s SCDHS requirements. We understand both frameworks and handle permit coordination as part of the job not as an afterthought.
It starts with a free estimate. Before any equipment shows up, you’ll know what the job entails and what it costs in writing. That’s not a formality; it’s the standard we hold ourselves to because the number-one complaint in this industry is a price that changes once the crew is on-site.
Once the estimate is approved, the permit process begins. In Selden, that means filing with the Suffolk County Department of Health Services under their Article 6 framework, and depending on your project type, potentially complying with Town of Brookhaven’s Chapter 78A nitrogen protection requirements as well. Permit processing typically takes two to four weeks, and we manage that process so you’re not navigating county and town paperwork on your own.
When permits are in hand, our crew handles everything from excavation through final setup. That includes breaking ground, removing or decommissioning the old system, installing the new tank and leaching structure, connecting to your home’s existing sewer line, backfilling, and restoring the site. Most residential installations in Selden wrap up within one to five days depending on system type and soil conditions. The sandy loam soil common in central Suffolk generally drains well, but every site gets evaluated individually before work begins. After installation, the system goes through a final SCDHS inspection before it’s signed off and live.

A full cesspool installation from us isn’t just dropping a new tank in the ground. The scope covers the complete system: excavation, decommissioning of the old cesspool, installation of the new tank and leaching pool or drywell, connection to the home’s sewer line, permit coordination with SCDHS and the Town of Brookhaven, and full site restoration once the work is done. One crew, one call, start to finish.
For Selden homeowners dealing with older systems, the work often involves more than a straight swap. Many of the postwar-era homes along and off Middle Country Road have cesspools with no documentation no records of where they’re located, how deep they go, or what condition the rings are in. We specialize in locating hard-to-find cesspools, which saves time, prevents unnecessary excavation, and gets the project moving without guesswork.
It’s also worth knowing that since July 2019, Suffolk County no longer permits a straight cesspool-for-cesspool replacement. Any system being replaced must include at minimum a septic tank preceding the leaching structure and for new construction in certain zones within the Town of Brookhaven, an Innovative and Alternative Onsite Wastewater Treatment system may be required. The rules have changed, and the right contractor knows them. We handle both residential and commercial properties in the Selden area.
