Your cesspool sits over your drinking water

The U.S. Geological Survey calls the aquifer under Long Island the only source of water for the Island, serving more than 2.8 million people in Nassau and Suffolk. Whatever leaves a cesspool soaks down through sand toward it. Suffolk County Planning estimates the average home septic system puts out about 40 pounds of nitrogen a year, and names cesspools and septic systems as the largest single cause of nitrogen pollution in the county's waters.

Questions people ask

How often does a cesspool need pumping?

Rapid Response Cesspool in Bay Shore says most Long Island households pump every 1 to 3 years, and a family of four in a three-bedroom house is often on about a two-year cycle (May 2026). For septic tanks, the EPA says household tanks are typically pumped every three to five years. More on the cesspool pumping page.

Can I replace an old cesspool with a new cesspool?

Not in Suffolk. Since July 1, 2019, replacing a cesspool or septic system there needs Suffolk County Department of Health Services approval, and the new system must have at least a septic tank in front of the leaching structure, per the Peconic Estuary Partnership. We have not found a matching published rule for Nassau.

Is there grant money to replace a cesspool?

Yes, in both counties, for nitrogen-reducing systems. Suffolk announced up to $45,000 in combined state and county grants on August 3, 2026. Nassau's SEPTIC program offers up to $20,000 to eligible homes not connected to a sewer.

Which license should a cesspool company have?

In Suffolk, a liquid waste license from the county Department of Consumer Affairs, with the endorsement for the job. In Nassau, the Office of Consumer Affairs licenses cesspool builders and cleaners under its home improvement license. The license guide shows how to look one up.
