Audits are conducted to review and evaluate utility companies’ expenses, plant-in-service, capital expenditures, and revenues. Investigations are performed to review and evaluate design, construction, and operations. Reports and correspondence from the Utilities Commission and other state agencies are reviewed regarding compliance with water quality and service.

Water Quality and Sewage Discharge The Utilities Commission does not directly regulate drinking water quality or the discharge of treated sewage. Divisions within the Department of Environmental Quality (DEQ) are directly responsible for these areas, but the Utilities Commission requires water and sewer companies to comply with the rules issued by DEQ’s Division of Water Resources. Utilities providing water service must comply with the rules and regulations established by DEQ’s Public Water Supply Section. Utilities that provide sewer services must comply with DEQ’s Water Quality Permitting Section rules and regulations in this regard.
