DC Water Statement on Revised Pepco-Exelon Merger Settlement Agreement

March 03, 2016

After careful consideration and consultation with the DC Water Board of Directors, CEO and General Manager George S. Hawkins announced today that DC Water will not support the revised Pepco-Exelon merger settlement agreement proposed by the Public Service Commission. DC Water has concluded the alternative terms in the revised agreement provide substantially less benefit to the Authority’s ratepayers than the negotiated settlement reached last October. DC Water will continue to seek opportunities to expand both green energy and green jobs, and we look forward to working with the District and other partners to advance those goals.

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.
