Septic System Professionals
Article VIII of the Laws of Westchester County refers to Sewerage, Sewage and Refuse. Its purpose is to ensure safe drinking water and to monitor wastewater treatment systems within the county. Changes in the sanitary code protect the environment and keep our water clean.

Professionals may view amendments and notices below:

The county's Septic Management Program protects the water quality of Westchester County. Under this program, the Health Department  licenses and trains septic company workers to ensure proper work is done. Westchester County requires contractors who pump out septic systems to file reports with the county's Health Department about every septic collection they make and sewage pumping stations are required to file annual reports documenting operations. Read our brochure Septic System Contractors Require a License for more information on licensing.
