REGIONAL SSO CONTROL: KEY ELEMENTS AND EXAMPLES FROM THE CITY OF DETROIT'S LONG-TERM WASTEWATER MASTER PLAN
Abstract:As part of its long-term wastewater master plan (WWMP), the Detroit Water and Sewerage Department (DWSD) is preparing a regional analysis to assist in eliminating sanitary sewer overflows (SSO) and to enable municipal customers to comply with federal and state SSO regulations. The purpose of the regional analysis is to find costeffective solutions for SSO abatement from the DWSD service area. Several local studies will be incorporated into the regional analysis. The analysis will evaluate the following alternatives:
Elimination of the sources of high infiltration and inflow (I/I) that cause SSOs
Local storage or treatment of SSOs
Regional transmission, storage, and treatment of SSOs
This paper first describes the DWSD service area and explains the short-term state regulations and potential long-term state and federal regulations driving the regional SSO analysis. Next, the seven key elements of the regional SSO analysis are outlined and explained. Finally, this paper provides examples of how the seven key elements are being applied in the DWSD service area and the corresponding results.
