Water Environment Research Foundation (WERF) Recognizes DC Water’s Biosolids Project as One of Greenest Projects in the World

October 19, 2011

The Water Environment Research Foundation (WERF) recognized DC Water with its Award for Excellence in Innovation Tuesday afternoon for its Biosolids Program, which will cut greenhouse gas emissions dramatically, produce more energy, and create higher quality biosolids – all combining to save millions of dollars annually when facilities begin operating in 2014. This new WERF award recognizes organizations that have made improvements to wastewater and stormwater collection, storage or treatment operations, facilities, or processes by applying WERF research. DC Water is one of two organizations to receive the award in its inaugural year. “This project resulted from long-term and extensive collaboration between WERF, DC Water, academia, and the wastewater industry to discover and develop new, key information and even new analytical methods,” said Walter Bailey, PE, DEE, Assistant General Manager, DC Water. “DC Water is unique in its long-term research programs, and that is what allows us to be at the forefront of wastewater technology deployment.” “We believe the process of research, modeling, and technology deployment is of profound importance to the wastewater and biosolids industry in North America and internationally,” states Selection Committee Chair and WERF Board Member Joseph Zuback of Global Water Advisors, Inc. “We recognize DC Water today for their commitment to advancing the industry and for this project that has significant green benefits.” Team members in this unique collaboration include DC Water, Bucknell Universityand the engineering team led by Brown and Caldwell. A team of WERF volunteers who themselves are some of the most recognized individuals in the water quality industry, selected the recipients from a field of many well-qualified organizations.

Trench boxes at construction site for new pit accessing Potomac Interceptor Upstream

DC Water and its contractors continue to make progress constructing new access points to the Potomac Interceptor, one upstream of the damaged section, and an additional entry downstream to divert more wastewater flow from the pipe. These access points will allow crews to install a bulkhead, blocking flow in the pipe upstream of the collapsed area, keeping the site as dry as possible so crews can safely remove an extensive rock dam currently blocking the pipe.

DC Water is releasing new findings regarding the environmental impacts following the January 19, collapse in a section of the Potomac Interceptor. Based on flow monitoring data collected before and after interim bypass pumping was activated, DC Water estimates approximately 243 million gallons of wastewater has overflowed from the collapse site.

Update on Extended Repairs, Safety Measures, and Water Quality Monitoring

Overnight CCTV inspection of the Potomac Interceptor revealed the blockage inside the collapsed sewer line is far more significant, showing a large rock dam stretching approximately 30 feet downstream of the original failure.
