Comprehensive Survey to Guide Rehabilitation and Address Changing Site Conditions
Starting later this week, DC Water will conduct an aerial drone assessment along the 54-mile Potomac Interceptor (PI) to evaluate current site conditions and better understand the changing landscape and development along the Potomac Interceptor alignment, including areas where there may be rocks or boulders that need further on the ground inspections.
DC Water has completed sludge removal on a section of the C & O Canal between locks 13 and 14, which was used as a bypass to divert wastewater around the collapsed section of the Potomac Interceptor and back into the pipe further downstream. Crews are now constructing an access bridge to this section of the canal to allow soil removal to begin.
As work nears completion on the initial clean-up and temporary stabilization of the areas directly impacted by the Potomac Interceptor overflows, DC Water is beginning preparations for beautification and revegetation to restore native plants, trees, and shrubs.
Before moving to the next phase of environmental rehabilitation, DC Water is working with the Environmental Protection Agency to conduct soil sampling to verify the clean-up efforts.
