Pressure Zone Improvement Program (PZIP) - Anacostia 2nd High
DC Water has completed its Pressure Zone Improvement Program (PZIP) for the Anacostia 2nd High Service Area. The planned increase in water pressure for more than 6,000 Ward 8 homes and businesses began on Monday, August 27, 2018 and ended on Tuesday, September 25, 2018.
In recent years, the community has expressed concern regarding low water pressure in southeast DC. To address these concerns, DC Water constructed the Anacostia Pumping Station, installed water mains, and built a two-million-gallon water storage tower on St. Elizabeths campus. The completion of the tower is the last in the series of projects that will result in the formation of the new pressure zone. This new infrastructure will produce an increase in water pressure of 22 pounds per square inch (psi) across the service area. The benefits of this project include not only improved water pressure, but also increased fire protection for all customers across the service area.
Following implementation of the pressure increase, some homes and businesses may experience water pressure exceeding 80 psi, which is regarded as high water pressure. Per the District of Columbia Plumbing Code, all buildings with high water pressure are required to have a pressure reducing valve (PRV) installed. If your single-family residential home was identified as one that will experience pressure higher than 80 psi as a result of the 22 psi increase and you have not yet had a PRV installed, you can still submit your Agreement, and we will call you to schedule a PRV installation appointment. If you own or manage a multi-unit building that will experience water pressure higher than 80 psi, we recommend that you consult a DC-licensed plumber to install a PRV.
For all customers whose homes will experience an increase in water pressure, DC Water recommends that you take steps to prepare your home for the upcoming pressure increase. Please ensure that your household plumbing is in proper working order. One way to do this is by checking all plumbing fixtures to ensure they are tightened. This general information is being provided as a cautionary measure, as the introduction of increased water pressure to any home plumbing system could possibly result in some leakage from pipes and faucets that are not in good condition or tightened securely. Should you have additional questions or require assistance in checking your plumbing system, DC Water suggests that you consult a licensed plumber.
