The Milwaukee Metropolitan Sewerage District (District) faced numerous challenges at their South Shore Water Reclamation Facility (SSWRF). The aeration blowers and engine generators, the energy center of the facility, had become unreliable, threatening effluent compliance and chronically impacting the operating budget. Upgrading the facility required comprehensive planning and a complex design and construction. The project included evaluation of alternatives for digester gas engine generators, electric driven or gas engine driven aeration blowers, replacement and upgrade of the electric power supply and distribution system, replacement of a multitude of key support systems, construction of the new facilities while maintaining operation and permit compliance, and a new energy operation model.
