Why do rates increase?

Because the water and wastewater treatment systems are aging, they must be maintained or replaced on a regular basis to ensure reliable service. The primary driver of rates increase is the amount of new and rehabilitation projects completed under the Detroit Water and Sewerage Department’s (DWSD) Capital Improvement Program. Frequently, new projects must also be undertaken to maintain compliance with increasingly stringent regulatory requirements. Operation & Maintenance (O&M) of the water and wastewater systems also impacts rates. Just like other systems that must be operated and maintained, DWSD’s and OCWRC’s systems are impacted by inflation and the cost of utilities, chemicals and property insurance. As new facilities are brought on line, overall expenses increase as well.
