Customer Testimonials

Mike and Nick, Jr. came over right away on a Saturday night. They took care of our cesspool issue and stuck to the fair price that we were quoted. These guys are great. As new homeowners with a growing family, there has been a bit of a learning curve to having a cesspool and the joys that come with it. The first time we needed to have the cesspool pumped, we used a different company. They took longer to come, did the same thing, and charged much more. Because these guys did the right thing, we will be using them again when we need to have the cesspool pumped and to help us get set up with the sewers that the town recently put in. If you have a cesspool that you need serviced, you should call these guys. They are awesome. Thanks again.

You bet.. 100%. This is why.
Had an emergency at my home; And couldn’t find anyone decent enough to do the job. Called Peconic Cesspool and no problem. A truck was sent within an hour as I was told.
John the tech, was very professional, friendly, knowledgeable and courteous. Great personality. Was very impressed at John since he is a very young man, but with the knowledge and professionalism of a person of many years.
Thank Peconic and thank you JOHN. (Still think my grandson looks like him.).”

Our Septic Tank Service Process

Our septic tank service process is designed for efficiency, safety, and long-lasting performance, ensuring your system receives thorough, reliable care from start to finish.

Septic Tank
Pumping
Process

Step 1: System Evaluation

Our technicians inspect the tank location, access points, and current system condition. This provides safe equipment setup and helps identify issues that may affect pumping or overall system performance.

Step 2: Accessing the Tank

We uncover and open the tank lids carefully, protecting your property while getting proper access. This allows our team to view internal conditions and prepare the system for pumping.

Step 3: Pumping the Waste

Using our professional equipment, we remove all solids and liquids from the tank. This clears blockages, prevents backups, and restores the system’s ability to process wastewater properly.

Step 4: Cleaning and Rinsing

The tank interior is rinsed to loosen remaining sludge, allowing for a more complete cleaning. This step improves system efficiency and helps identify any hidden damage or structural issues.

Step 5: Final Inspection

After cleaning, the technician checks baffles, filters, and structural components. We check that everything is functioning correctly and will check for early signs of wear before they become major problems.

Septic Tank
Installation
Process

Step 1: Site Evaluation and Permitting

Our technicians inspect soil conditions, your property layout, and local regulations to design a compliant system. Necessary permits are secured so the septic installation meets health, safety, and environmental standards.

Step 2: Excavation and Ground Preparation

The installation area is carefully excavated to the required depth. The ground is leveled and prepared, providing a stable base for the tank and proper drainage flow throughout the system.

Step 3: Tank Placement and Positioning

The septic tank is lowered into the excavation using our professional equipment. Technicians make sure it’s level, secure, and positioned correctly to support wastewater flow and long-term system performance.

Step 4: Connecting Pipes and Components

Inlet and outlet pipes are installed and securely connected to the home and drain field. Additional components such as filters and risers are added to optimize efficiency and future maintenance.

Step 5: Backfilling and System Testing

The tank and piping are covered with soil once alignment is secured. The system is tested for proper flow, functionality, and sealing to ensure reliable, safe operation before final site restoration.
