Summary:
Long Island Cesspool Installation Requirements in 2024
The most significant development in 2024 centers around enhanced enforcement and expansion of nitrogen-reducing system requirements, with new technologies that reduce nitrogen in residential wastewater by up to 70%. This isn’t just bureaucratic red tape—it’s about protecting Long Island’s sole-source aquifer that millions depend on for drinking water.
Suffolk County banned traditional cesspool installation effective July 1, 2019, with 2024 updates strengthening enforcement while expanding support programs. Nassau County has similar restrictions. What this means for you: any new cesspool installation must use advanced nitrogen-reducing technology.
More Long Island properties now fall under requirements for advanced wastewater treatment systems. The days of simple concrete rings are over.
What Advanced Nitrogen-Reducing Systems Actually Mean
Let’s cut through the technical jargon. Conventional septic systems and cesspools are not designed to remove nitrogen, so nitrogen in sewage easily seeps into the ground, then to groundwater, and ultimately to our bays and harbors where it can lead to excess nitrogen and algae blooms.
The new systems—called Innovative and Alternative Onsite Wastewater Treatment Systems (I/A OWTS)—are engineered differently. IA OWTS systems have been shown to remove up to 90% of the nitrogen that leads to these environmental problems. Think of them as cesspool systems with built-in water treatment technology.
The average total cost for nitrogen-removing I/A systems is approximately $25,000, though costs vary on a case-by-case basis with an average total cost of $19,200, contingent on system requirements and site constraints. Yes, that’s more expensive than old-style cesspools. But here’s where it gets interesting.
Nassau County offers grants up to $20,000 for homeowners, and Suffolk County provides a $10,000 grant, with an additional $5,000 for low to moderate income applications and $5,000 when a Pressurized Shallow Drainfield is required. In some cases, it may be possible to receive a combined $25,000 grant for septic systems on Long Island—covering the costs of the installation of a nitrogen reducing septic system.
This changes the math completely. What looked like a $25,000 project could cost you $5,000 or less out of pocket.
Permits and Inspection Process Made Simple
You may need a permit to install a replacement cesspool, depending on your property and the system’s design, and this step must be completed before installation can begin. The permit process isn’t as complicated as it sounds when you work with the right contractor.
Cesspool installation requires permits from local health departments in both Suffolk and Nassau Counties, with permit costs typically ranging from $200-500 depending on system size and local requirements, and processing taking 2-4 weeks for approval.
The process includes site assessment with soil percolation testing, distance verification to wells and buildings (minimum 100 ft), groundwater depth checking, securing all Nassau or Suffolk permits, and submitting system design to county health department.
Here’s what most homeowners don’t realize: installation teams coordinate with local health departments to schedule required inspections at excavation, tank placement, and backfill stages, and experienced contractors obtain all required permits and schedule inspections to keep your installation on track and compliant.
The key is choosing a contractor who handles this process routinely. Licensed contractors are familiar with all local Long Island Township & New York State Health Department codes and will arrange for and complete the inspection process from start to finish. This isn’t where you want to learn on the job.

Cesspool Installation Process and Timeline
New cesspool installations typically take 1-2 days for residential properties, depending on soil conditions and system complexity, with coordination with local health departments to schedule required inspections during construction phases. That’s faster than most homeowners expect, but the timeline depends heavily on preparation.
Installing a cesspool is a complex process that requires careful planning and execution, and following proper steps will help ensure that the cesspool is properly installed and functioning correctly. The actual installation moves quickly when everything is planned correctly.
Step-by-Step Installation Process
The installation process follows a specific sequence that experienced contractors know by heart. The first step in installing a cesspool is to excavate the area where the cesspool will be located, and this should be done carefully and with the help of a professional.
The installation process includes soil percolation testing to determine proper system sizing and placement, precise excavation to avoid utility lines, and installation of distribution systems that maximize treatment area while meeting setback requirements from wells and property lines.
Once the site has been prepared, the cesspool and all associated plumbing and drainage pipes are installed, gravel may be packed around drainpipes to provide stability, and when installation is complete, the excavated area is filled in and the entire septic system is inspected before it is put into use.
Modern cesspool systems include multiple components that work together for effective waste treatment, with precast concrete tanks providing durable waste collection with engineered baffles that separate solids from liquids, and distribution boxes directing effluent flow to absorption areas sized for your soil conditions and household capacity.
The difference between a good installation and a great one comes down to details. Proper installation includes graded stone backfill around distribution lines and geotextile fabric that prevents soil infiltration while maintaining drainage, with testing of all connections and verification of proper slopes before final backfill to prevent future access problems.
What Can Go Wrong and How to Avoid It
Not checking for permits before installing a cesspool can result in costly fines and delays. This is the most common mistake homeowners make—assuming their contractor handles everything automatically.
The type of soil in the area where the cesspool is to be installed will determine the size and type of cesspool that is needed, and it’s important to consult with a professional to ensure that the correct cesspool is chosen, because installing a cesspool that is too small can lead to frequent overflows and costly repairs.
You’ll never worry about hidden costs, project delays, or damage to your property when you work with experienced contractors who understand these potential issues upfront.
Most Long Island septic system installation and replacement companies and septic repair contractors do not have the experience, know-how and equipment to complete the job on budget and right the first time, with broken septic tanks, septic pipes and leaching fields affecting homes and businesses throughout Long Island, and the variety of septic tank and systems to choose from making new septic system installation overwhelming.
This is why contractor selection matters more than price. The safety concerns and financial liabilities that can arise from anything less than a perfect tank installation are too great to take a chance, so don’t trust an inexpensive price—expertise comes with a price but it is well worth the investment.
