Capital breaks ground
18 October 2011The District of Columbia Water and Sewer Authority (DC Water) broke ground last week on the USD 2.6bn Clean Rivers project, which will construct two tunnels to store the combined sewage during rain events.
The 23ft (7m) diameter Blue Plains tunnel will be excavated in depths more than 100ft in soft ground as it extends from Blue Plains, along the coast of the Potomac River, crossing under the Anacostia River to RFK Stadium.
A USD 330.5M contract was awarded to a joint venture of Traylor Brothers-Skanska-JayDee for design and construction of the 23,600ft (7.2km) long Blue Plains tunnel this spring.
CSOs in the area direct about 2.5 billion gallons of combined sewage into the Anacostia and Potomac Rivers and Rock Creek in an average year.
