Water and Wastewater Division

The Commission’s primary responsibility regarding water and wastewater utilities is to regulate rates and charges and the quality of service for the utilities under its authority. Proceedings before the Commission can be complex, sometimes taking 12 to 18 months to complete. These proceedings include, but are not limited to, rate changes (through base rate cases, distribution system improvement charges, and periodic trackers), certificates of territorial authority for not-for-profit and investor-owned utilities, acquisitions, service area matters, and conservation initiatives.

Below you will find rate comparison data, utility tariffs, 30-day filings, lists of jurisdictional and withdrawn utilities, industry reports, links to federal resources, and administrative materials and forms for regulated utilities.

To contact the Water and Wastewater Division with any questions or to request copies of utility tariffs and annual reports submitted by regulated utilities, please call 317-232-2785.
