Hydrant Inspections May Cause Temporary Water Discoloration

June 15, 2007

The District Department of Fire and Emergency Services (FEMS) is inspecting hydrants in areas throughout the city by turning them on to ensure that they are in good operating order. This high velocity flushing can cause a temporary discoloration of water when materials, like iron from pipes, dissolve into water delivered to the tap. In these situations, the District of Columbia Water and Sewer Authority (WASA) provides this guidance for consumers who may experience discolored water:

• Do not drink, cook or do laundry with discolored water
• Do not run the hot water (because sediment could settle in your water heater)
• Run the cold water until it is clear

If the water does not clear after 10 minutes, discontinue water use for 30 minutes, then run water for 10 minutes again. If the water is still discolored, call the WASA 24-hour Emergency Services Line at (202) 614-3400 and a flushing crew will respond.

WASA, which operates and maintains more than 9,000 hydrants in the District, is working jointly with the District fire department (FEMS) on a multi-year Hydrant Upgrade Program. As fire department personnel complete a comprehensive inspection of every hydrant in the system, WASA flushing crews have been put on extended hours to respond to areas where there have been calls concerning discolored water.

DC Water has completed the first major step in emergency repairs to a 175-foot section of the Potomac Interceptor near Pennyfield Lock in Potomac, Maryland. Crews added a new, stronger lining inside the pipe after inspections found serious wear and damage. The work is part of ongoing repairs to 1,700 linear feet of pipe near Pennyfield Lock. Work began on Friday to apply geopolymer, a concrete-like material, inside the pipe. With the new lining complete, crews are preparing for the next phase of work for the remainder of the pipe segment.

DC Water Breaks Ground on Piney Branch Tunnel, Final Phase of DC Clean Rivers Project

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.
