Municipal Water Systems (Public Water Utilities)

A 'municipal water system' (a.k.a., a water utility) generally refers to an organization engaged in furnishing water to the public within a municipal or regional division for household or drinking purposes. Usually, these utilities are owned and operated by either local (municipal) government agencies or quasi-autonomous corporations governed by a board of trustees, although private utilities do exist. Still, even if a utility does not fall under the auspices of a particular governmental entity, the system is subject to government regulation in the public’s interest.

In Maine, municipal water systems are regulated by the Drinking Water Program to ensure compliance with the Safe Drinking Water Act. The DWP provides regulatory oversight of water sources and retrieval, treatment, storage, and distribution to consumers, all with an eye to protecting public health. The DWP is not involved in oversight of a water utility’s business operations or consumer relations.

All concerns or complaints regarding a water utility’s business practices and management, or questions concerning rates, billing, and/or access to service should be directed to the Maine Public Utilities Commission (PUC).

The table below lists all of the municipal water systems in Maine (including links to their websites), their extended service areas, and – in the third column – the DWP inspection district in which they are located and the Public Water System Inspector responsible for that district. Please note: not all municipal water systems have a web presence. While we have attempted to provide as comprehensive a list as possible, updates to these listings are always welcome and may be sent to the DWP web manager.

Please note: Inspection for systems in District J (northern Maine) is currently a vacant positon. For information regarding DWP oversight of these systems, please call the DWP main line at (207) 287-2070.
