System Assets

The Downriver Sewage Disposal System (DSDS) consists of a wastewater treatment plant which is situated on a 34 acres site in the City of Wyandotte, Michigan, along with several miles of interceptor pipe and a wet weather tunnel system, which is used to convey wastewater from 13 Communities.

The wastewater plant treatment process consists of influent pumping, preliminary treatment, primary treatment, secondary treatment (high-purity oxygen activated sludge with secondary settling), and UV disinfection. Chemical addition is used to facilitate phosphorus removal, and the biosolids generated in the treatment process are dewatered at the plant and transported off-site for disposal.
