 Trustindex verifies that the original source of the review is Google. Clear River Environmental are the best.  My cesspool collapsed and in less than 24 hours I have a new septic system.  Jaun, Jaime. Alex and Manny are some of the most skilled professionals I’ve ever seen.  They took great care, left my sprinkler lines easily accessible as well as carefully cutting out the one piece of the walk so that I can access it later.  The price was extremely fair and the service was second to none.  If you ever have an issue plumbing or sewage related, do yourself a favor and call Clean River!  Thanks again!!!

 Trustindex verifies that the original source of the review is Google. We needed to upgrade our septic system due to a recent renovation. After careful vetting, we chose Clear River Environmental, and it was a very wise choice. From Steve who guided us through the paperwork, to Patricia who planned and confirmed the schedule, to the team that was at our home for two days, Bravo!. The field crew was awesome, they worked together like a well oiled machine. They had everything they needed on their trucks. They had our new I/O system completed in two days, which was amazing considering they buried a 1,000 gallon tank, eight 6' wide x 8' long x 2' deep leaching pools, and then two 8' wide x 2' deep drywells with piping from our gutter down spouts. They paid great attention to detail, used caution around our driveway, our two big oak trees and our landscaping. They left our home better than broom clean. We are ready for some sprinkler system repairs (they did a great job lifting pipes and not destroying what was there) and left us ready for top soil and grass seed. We have no afilliation with Clear River, we are just another one of their satisfied customers.

 Trustindex verifies that the original source of the review is Google. Clear River Environmental provided top tier service. We updated our block cesspool to an IA/OWTS system with the help of the Suffolk Septic Improvement Grant. My cesspool company Finest Cesspool referred me to Clear River. I spoke with Steve at their office once our grant was approved and they assisted us every step of the way.The engineer was very transparent and helpful. Explaining the benefits to the environment of the new system and what we should expect going forward. Installation day was very smooth. The team went out of their way to avoid doing any unnecessary damage to our back yard. Especially our patio concrete when they managed to only cut out a small piece to access our waste pipe. They even salvaged any lines of our sprinkler system that had to be cut. Excellent service all around. I would highly recommend this company.

 Trustindex verifies that the original source of the review is Google. I am extremely pleased with the installation of my SeptiTech STAAR Model .5 septic system with GeoMat technology.  John took the time to explain how the system works for me and the great benefits it will bring to our environment in the future. John, Tommy and the rest of "The A Team" were very professional, did a great job and finished in a day...  The rainy weather did not slow them down one bit..  They left my yard clean and raked out, ready for seed.. I will definitely recommend John and Clear River Cesspool to friends and family..

Frequently Asked Questions

Q1. How often should I pump my septic tank on Long Island?

Most Long Island homes should pump their septic tank every 2–3 years, but high usage, older systems, or large households may require more frequent service to prevent backups and costly repairs.

Q2. What are the signs my septic system is failing?

Common signs include slow drains, sewage odors, pooling water in the yard, and gurgling pipes. Immediate inspection is recommended to avoid contamination and expensive system replacement.

Q3. How often does a cesspool need pumping in Long Island?

Cesspools typically require pumping every 1–2 years due to faster solid buildup, especially in Suffolk County where older systems are common.

Q4. What is the difference between a cesspool and a septic system?

A cesspool stores waste without separation, while a septic system treats and separates solids and liquids, making septic systems more efficient and environmentally safer.

Q5. What causes frequent drain clogs in homes?

Common causes include grease buildup, hair, soap residue, tree roots, and flushing non-degradable items, all of which restrict water flow and lead to recurring blockages.

Q6. When should I call a professional for drain cleaning?

If you experience slow drains, recurring clogs, or foul odors, professional cleaning is needed to prevent pipe damage and complete system blockage.

Q7. What are the warning signs of a sewer line problem?

Multiple drain backups, sewage smells, soggy yard areas, and sudden pest issues often indicate a damaged or blocked sewer line requiring immediate inspection.

Q8. How is a sewer line inspected without digging?

Professionals use sewer camera inspections to identify cracks, blockages, or root intrusion, allowing accurate diagnosis without unnecessary excavation.

Q9. What qualifies as a plumbing emergency on Long Island?

Burst pipes, major leaks, sewage backups, and no water supply are considered emergencies and require immediate professional repair to prevent structural damage.

Q10. How can I prevent plumbing issues in my home?

Regular inspections, avoiding grease disposal, maintaining pipes, and addressing small leaks early can prevent costly plumbing repairs and system failures.

Q11. Do you offer same-day septic or plumbing services on Long Island?

Many providers offer same-day or emergency services for urgent issues like backups, overflows, and leaks to restore functionality and prevent further damage.

Q12. How much do septic, cesspool, or plumbing services cost in Long Island?

Costs vary based on service type, system condition, and urgency, but routine maintenance is significantly more affordable than emergency repairs or full replacements.
