PC Construction wins $215 million joint venture project to help DC Water with Clean Rivers Project

first_imgPC Construction,The PC/CDM Joint Venture, which brings together the industry-leading expertise in water treatment facility design and construction of PC Construction and CDM Smith, has been awarded the approximately $215 million Tunnel Dewatering Pump Station & Enhanced Clarification Facility project for DC Water.The design-build project will be constructed at the Blue Plains Advanced Wastewater Treatment Plant in Washington, DC. The tunnel dewatering pump station (TDPS) and the enhanced clarification facility (ECF) are part of the larger DC Clean Rivers Project, mandated under a Federal Consent Decree between the United States, the District Government and DC Water, to build tunnels to temporarily store combined sewer (sanitary and storm) overflows until they can be pumped to the treatment facility. Currently, rainwater from DC Water’s 725-square-mile service area can overwhelm the system and treatment facilities with a diluted mix of rainwater and sewage, resulting in potential overflow into the Anacostia and Potomac rivers as well as Rock Creek.Major project components include the construction of a 250 million gallons per day (mgd) TDPS which will pump a diluted mix of rainwater and sewage to the ECF. The new, 250 mgd ECF will utilize a ballasted high-rate clarification process. Treated water will be disinfected before discharge to the Potomac River. The TDPS and ECF will be expandable to 500 mgd in the future.The design phase of this project will begin in August, with construction following shortly thereafter. The overall tunnel project for DC Water is expected to be completed by March 2018.Since 2010, PC Construction has worked on four other projects for DC Water with a total estimated value of $375 million.‘We are pleased to work with the PC/CDM Joint Venture on this important component of our wet weather plan,’ said DC Water General Manager George Hawkins. ‘The projects that make up the wet weather plan achieve both nitrogen reduction and CSO abatement, improving the health of our waterways and saving hundreds of millions of dollars.’‘This massive project was awarded to the PC/CDM Joint Venture because of our successful performance on multiple projects with DC Water, and because we go above and beyond on every job,’said Kevin McCarthy, president of PC Construction. ‘This was an ‘all-in’effort throughout the procurement process with PC Construction’s operations, business development, estimating andscheduling groups ‘and our partners at CDM Smith ‘working night and day to meet the needs of DC Water and the residents, businesses and organizations in our nation’s capitol.’‘CDM Smith partnered with PC Construction based on a long history of successful projects and shared values between the firms,’said David Schwartz, vice president with CDM Smith. ‘We have also developed excellent working relationships among our local staff through over $300M of design-build work delivered or under contract in the DC Metropolitan area, including DC Water’s Biosolids Main Process Train, one of the greenest projects in the region.’About PC ConstructionPC Construction offers general contracting, construction management and design-build services to private companies and public entities of all sizes.
