WASA Reschedules Public Meeting on River Cleanup Efforts

November 03, 2006

WASA has rescheduled the Combined Sewer Overflow (CSO) meeting at the Petworth Neighborhood Library located at 4200 Kansas Ave, NW for Monday, November 13, 2006 from 7-8 pm.

The meeting at the Southeast Neighborhood Library located at 403 7th St., SE will be held on the scheduled date of Thursday, November 9, 2006 from 7-8 pm

The meetings will include discussions with the community about WASAs $2.1 billion plan to control water pollution and flooding caused by the Districts combined sewer system.

A combined sewer is a single pipe that carries both sanitary wastewater and storm run-off. During certain rainfall conditions, the capacity of a combined sewer may be exceeded. When this occurs, the excess flow, a dilute mixture of wastewater and stormwater run-off (called Combined Sewer Overflow or CSO), is discharged to the Anacostia River, Potomac River, Rock Creek and tributary waters.

The presentations will focus on WASAs efforts to control this discharge and improve the environmental and economic health of the rivers and other bodies of water in the District. Current CSO activity taking place throughout the District will also be highlighted.

Everyone is invited to attend.

Work is nearly complete on the downstream section of the Potomac Interceptor to reinforce the pipeline with geopolymer. The concrete-like material will strengthen and restore the structural integrity of the pipe. Completion of the geopolymer lining downstream is one of the final steps to restore flow to the interceptor and finish the emergency repair.

This comes one month since the last overflow reached the Potomac River.

geopolymer downstream

As emergency repairs continue, today marks 27 days, nearly one month, with no overflow reaching the Potomac River.

Crews are making significant progress to reinforce the downstream section of pipe from the collapse site and completed 240 linear feet of geopolymer overnight. Crews are working to apply another layer of geopolymer today. The material is similar in strength to concrete and when applied restores the structural integrity of the pipe.
