Information for public water system owners and operators

“Public Water System” means a system for the provision to the public of piped water for human consumption, if such a system has at least 15 service connections or regularly serves an average of at least 25 individuals daily at least 60 days out of the year.

Types of public water systems

A public water system can either be a community system, like a municipality, mobile home park or subdivision; or a non-community system, like a school, factory or wayside. (See diagram [PDF]) If you provide drinking water to the public and your water system meets the definition stated above, you're a public water system owner/operator.
