DC Water holds two public meetings on proposal to modify Long Term Control Plan to include green infrastructure

January 30, 2014

DC Water’s Clean Rivers Team will publicly present and explain its proposal to leverage green infrastructure (GI) to reduce combined sewer overflows into the Potomac River and Rock Creek while greening portions of the District on a large scale.

The public is encouraged to attend to learn more and to submit comments on the proposal.

The meetings will be held the week of February 17, as follows:

• February 18, 2014, beginning at 7:00 p.m.
Georgetown Visitation Preparatory School (1524 35th Street NW)

• February 20, 2014, beginning at 7:00 p.m.
Petworth Public Library (4200 Kansas Avenue NW)

Green infrastructure is a natural way to manage stormwater, by absorbing rain before it makes its way to the sewer or stormwater system. Examples include green roofs, bioretention, rain barrels and pervious pavement. Keeping stormwater out of the sewer system can go a long way to improving the health of our local waterways, since it contributes to combined sewer overflows (CSOs) in heavy rain storms. The plan calls for a nearly $100 million investment to green areas of DC that are impacted by combined sewer overflows (CSOs).

Pennyfield Lock Potomac Interceptor bypass pipeline running next to C & O Canal with equipment

There is no active spill or overflow. Work to strengthen the pipe to begin soon.

Today, DC Water completed construction on a temporary bypass system as part of sewer repairs on the Potomac Interceptor near Pennyfield Lock in Potomac, Maryland. Crews turned on the pumps and successfully tested the system. With the bypass now ready, it will allow us to begin the emergency repairs inside the pipe by carrying the wastewater around the repair area.

Today, DC Water broke ground on the Piney Branch Tunnel, the final major tunnel in our Clean Rivers Project. This work will help keep sewage and trash out of local waterways and make Rock Creek, the Potomac River, and the Chesapeake Bay cleaner for our community.

When we finish the Piney Branch Tunnel, it will hold at least 4.2 million gallons of rainwater and wastewater during heavy storms. Instead of overflowing into Piney Branch, that water will go to the Blue Plains Water Resource Recovery Facility, where it will be treated.

Starting the week of July 13, 2026, people who live, work or travel near the Canal Road NW entrance to Georgetown University may hear controlled blasting. This work is part of our Potomac River Tunnel Project.

When blasting happens, neighbors may hear a brief noise or feel light shaking. Drivers, cyclists, and pedestrians on Canal Road NW may also be stopped for a few minutes while we safely complete each blast.
