OREANDA-NEWS. CH2M and Parsons, as part of a joint venture team, have been selected by the District of Columbia Water and Sewer Authority (DC Water) to perform program management services for the development and implementation of DC Water’s capital improvement program (CIP)—a $1.3 billion water and wastewater infrastructure program focused on repair and replacement of mostly underground infrastructure in Washington, D.C., and neighboring jurisdictions. 

The three-year contract, with options for renewal up to two years, combines two separate program management contracts into one large program – providing greater efficiencies in delivery and cost. The CIP includes the planning, design and construction of linear and vertical infrastructure in the water and wastewater service areas, including piping, pumping, storage and other appurtenance structures, such as hydrants, valves, inflatable dams, diversion structures and manholes. The program includes rehabilitation or replacement of small- and large-diameter water mains; rehabilitation of water, sanitary and storm pumping stations; rehabilitation of minor and major sewers and storage facilities; and condition assessments of water and wastewater buried infrastructure, pumping stations and storage facilities.

Repair and replacement strategies are complicated in dense urban areas with complex underground infrastructure, and therefore must be coordinated carefully with a wide variety of stakeholders. As the CIP program manager, the CH2M/Parsons JV team will also help DC Water coordinate with stakeholders throughout Washington, D.C. neighborhoods.
