"I called and got a friendly greeting. 
The service call came right on time and did a nice job.
i didn't have a problem but I had never had the cesspool pumped in 22 years.
OK, it was a brand new cesspool 22 years ago and my first house so I am really clueless.
I am told to pump it every 5 years so I guess I was over due. 
Not having a clue I only had an idea of what the cost was through the phone call I had made to the company. 
I was told $485 but was charged extra for aeration , chemicals and a tube going to the over flow tank. 
In total it was $750 with my Angie's List 10% off. 
Not to bad considering I never had it done before. 
Ray & Paul were very good at what they do, professional and got me up to speed on what was going on. 
I recommend using them!

"Review for Cesspool Services I recently had the pleasure of working with Cesspool R Us for our property’s cesspool maintenance, and I couldn’t be more pleased with the experience. From start to finish, the team demonstrated professionalism, expertise, and attention to detail that made the entire process smooth and stress-free. The technicians arrived promptly, fully equipped, and ready to get to work. They took the time to explain the process clearly and answered all of my questions, which was greatly appreciated. The work was done efficiently, and they ensured that the area was left clean and tidy, going above and beyond in their commitment to customer satisfaction. What really stood out was their knowledge and thorough approach. They identified and addressed potential issues I wasn’t even aware of, which saved us from potential future problems. It’s rare to find a company so dedicated to quality service and customer care. I highly recommend Cesspool R Us for anyone in need of reliable, high-quality cesspool services. Their team is skilled, respectful, and truly dedicated to doing the job right. Thank you for providing such excellent service!"

"Mike was very nice. He explained everything he was doing and had me look at what he was doing. My son is in the Army and Mike gives military discounts which helped with the price. He took his time finding the septic covers and cleaning two pools out. He cleaned up when he was done. Mike even placed the sections of grass he removed back in place. I could barely tell he d dug such a large hole. I would use Great South Bay Environmental again and I definitely recommend him."

Septic Tanks FAQs, answered by experts

According to the Environmental Protection Agency (EPA), septic tanks must be located a decent distance from places subject to flooding or surface ponding. Additionally, septic tanks should be installed on level ground so that the waste can properly settle in the tank. Most tanks are located 10 to 20 feet away from the home. More specific requirements vary by location, so call a local septic pro or your local health department for more information.

A properly installed and maintained septic drain field (also known as a leach field) can last up to 50 years, though the average is around 20 years. However, factors like poor soil conditions, heavy usage, or improper maintenance can significantly shorten its lifespan to 15-20 years.

To extend the life of your drain field:

  • Schedule Regular Inspections: Have the entire septic system, including the drain field, inspected every two to five years to catch problems early.

  • Protect the Area: Avoid driving heavy vehicles or placing heavy structures over the drain field. Plant only grass or other lightweight vegetation with shallow roots over the area.

  • Maintain the Septic Tank: Proper care of the septic tank, including regular pumping and avoiding harmful chemicals, prevents strain on the drain field.

Be aware of signs of failure, such as strange odors, standing water, or unusually lush grass over the field, which indicate your system may need professional attention.

A septic system can fail for various reasons, and most commonly, excessive water use or sudden surges in wastewater can overwhelm the system's capacity. Neglecting regular maintenance, like tank pumping and inspections, can also lead to clogs, leaks, and eventual breakdowns. Other issues that lead to failure include age-related wear and tear, root infiltration, improper disposal of non-biodegradable materials or chemicals into the system, unsuitable soil conditions, physical damage, and even environmental factors like flooding or soil erosion.

Mound systems can fail if foreign objects are flushed into the septic tank, the septic tank is backed up with solid waste (sludge), if wastewater floods or seeps from the mound, or if any part of the system is clogged. To prevent this, only flush toilet paper and your normal “business” down toilets, and get a septic inspection at least yearly.

All municipalities in the U.S. require a permit for septic tank installation or septic system alteration, and the permit will usually cost between $450 and $2,500. Some municipalities also require permits for septic system repair. You’ll either need to contact your local building department or your septic tank company to ask if this is necessary before carrying out the work. Permits are not typically required to have your septic tank pumped, so provided your septic company is licensed, you can move forward with the work as needed.
