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.

This page contains information and resources you need to have your private water supply correctly built and adequately protected.

How deep is my well?
  • Go to the well records search and find the Well Construction Report for your well. The report will indicate the drillhole depth and the casing depth. If you cannot find a Well Construction Report for your well, you can hire a licensed well professional to inspect the water supply system and measure the well depth for you.
