Anacostia 2nd High Residential Pressure Reducing Valve Installation Project
As part of its Capital Improvement Program, DC Water has initiated the Anacostia 2nd High Residential Pressure Reducing Valve Installation Project to address long-standing issues and community concerns regarding low water pressure in Ward 8. To address the low pressure issue in area homes and in the vicinity of Hadley Hospital, Greater Southeast Hospital, Saint Elizabeths Hospital and Congress Heights, DC Water has started work on the Saint Elizabeths Water Tower and Large Diameter Transmission Main project, which is scheduled for completion in spring 2018.
This project will be the last in a series of projects that will result in the formation of a new pressure zone in the areas stated above. There will be an increase in water pressure of 22 pounds per square inch (psi) across the service area following completion of the work. The benefits of this project will not only include increased water pressure, but also increased flow from local fire hydrants.
Scope of work
DC Water has identified homes and other buildings within the service area that will likely experience water pressure exceeding 80 psi following the implementation of the 22 psi pressure increase. According to the District of Columbia Plumbing Code, pressure at this level requires installation of a pressure reducing valve (PRV) inside the property. As part of this project, DC Water is contacting affected property owners to make them aware of the future water pressure increase and the need to have a PRV installed. If permitted by the property owner, DC Water’s contractor will purchase and install a PRV in eligible residential properties at no cost to the property owner. DC Water’s contractor will schedule an appointment with the owner or his/her representative to install the PRV prior to the scheduled water pressure increase.
Information will also be provided to affected property owners whose homes will experience increased pressure but will not require PRV installation.
