Public Water System is defined as any source(s) or combination of sources owned or controlled by a person, that provides drinking water through pipes or other constructed conveyances to the public and that has at least fifteen (15) service connections or serves an average of at least twenty-five (25) individuals daily for at least sixty (60) days out of the year. Such term includes all collection, treatment, storage and distribution facilities under the control of the water supplier and used primarily in connection with such system, and any collection or pretreatment storage facilities not under such control which are used primarily in connection with such system. Public water system shall also mean any part of a system which does not provide drinking water, if use of such a part could affect the quality or quantity of the drinking water supplied by the system. Public water system shall also mean a system which bottles drinking water for public distribution and sale (see also Domestic Bottled Water System).

- Potable (Non-Public) Water Supplies (Regional Offices) include those requiring permits and those not requiring permits. Examples of non-public water systems requiring permits are some 9 lot-or-fewer subdivisions, and public buildings serving fewer than 25 people. Non-public water systems not requiring permits, such as single family homes on lots not subject to state subdivision rules, have no direct responsibilities under the rule, and are regulated indirectly by the standards in Part 12 of Appendix A and the Well Driller Licensing Rule in Chapter 15 of the Environmental Protection Rules. These systems are not included in the categories addressed here. Regional Office should be contacted regarding what permits and requirements are relevant to these water systems. NOTE: A municipality must issue letters authorizing connection to, or for an increase in flow to, their wastewater treatment facility for any project that is subject to a Wastewater System and Potable Water Supply Permit.
