Water Industry Overview
The Division of Water, Compliance and Consumer Affairs (DWCCA) is responsible for carrying out the PSC’s
regulatory authority related to water and wastewater utilities. This oversight includes:
Drinking Water Utilities
The PSC oversees more than 580 drinking water utilities operating in Wisconsin, including municipal and
investor-owned utilities. The PSC’s authority extends to any water system that provides water to the
public for domestic, commercial, or industrial purposes. However, regional water authorities, cooperatives,
water trusts, and private wells are generally not subject to PSC regulation. The PSC’s water fact sheet provides more information about the water utility industry in Wisconsin.
The PSC regulates nine of the more than 600 wastewater (sanitary sewer) utilities operating in Wisconsin.
Local governing bodies are responsible for the operations and rates for unregulated sewer systems; however, the PSC may get involved in customer complaints or disputes about rates and practices
for any wastewater utility in the state.
