The Detroit Water and Sewerage Department (DWSD) seeks to help customers reduce your drainage charge by verifying your parcel information, installing green infrastructure practices to receive a monthly credit, and/or participating in credit programs available to institutions.

The guides and forms listed below reference current available assistance. A credit calculator is also available to provide estimates for credits for stormwater management practices.
