Information for private well owners
Private wells are wells that are not part of a public water supply. Private wells have fewer than 15 connections and serve fewer than 25 people. They are usually wells that serve a single home or farmhouse. Unlike public water systems, protection and maintenance of a private well is largely the responsibility of homeowners.
