Conventional Septic System Installation & Replacement on Long Island

Discount Cesspool & Drain installs and replaces conventional septic systems for homes and businesses across Suffolk County, Nassau County, and all of Long Island. Whether you are building new, upgrading an aging system, or replacing one that has failed, our experienced crews handle the entire job from permits to final inspection, and every estimate is free.

When You Need a New or Replacement Septic System

Conventional septic systems do not last forever. Signs it may be time to replace yours include slow drains, frequent backups, sewage odors, wet or spongy ground over the leaching area, and unusually lush grass above the tank. Older systems, or a failed inspection when selling a home, often call for a full replacement. We help you understand your options and recommend the right system for your property, soil conditions, and budget.

Our Installation and Replacement Process

Every job starts with a free, on-site estimate. From there we handle the design, secure the required Suffolk County and local permits, prepare the site, and set high quality precast tanks and leaching components. When we replace a failed system, we remove and properly dispose of the old one, then backfill, grade, and coordinate the final inspection so everything meets code. We work cleanly, protect your property, and keep you informed at every step.

Most conventional septic installations and replacements are completed in a day or two, with minimal disruption to your property and a thorough cleanup when the job is done.
