Wells

Wells

About one-quarter of Wisconsin's population drinks water drawn from over 800,000 private wells. Wells are safe, dependable sources of water if sited wisely and built correctly. Unlike public water systems, the protection and maintenance of a private well is largely the responsibility of homeowners.
