Pittsburgh, PA – Today, the Pittsburgh Water and Sewer Authority is completing the final phase of major renovations to half of the Lanpher drinking water reservoir located in Shaler Township. The project involved replacing the liner and cover of the west cell of this critical treated drinking water storage facility that provides water to one-third of PWSA’s customers in northern neighborhoods of the City of Pittsburgh, as well as the Borough of Millvale and Reserve Township.
“A renewed Lanpher Reservoir ensures that PWSA will continue to provide safe and reliable water to our customers for decades to come. I applaud our team of PWSA employees and contractors who worked together to get the job done for our customers,” said PWSA Executive Director Robert A. Weimar.
Storage in the form of reservoirs and tanks is the backbone of all major drinking water distribution systems. PWSA’s reservoirs provide backup water supply and reduce the need for pumping. In addition, the reservoirs are strategically located at a high elevation to supply the pressure needed to move water throughout the service area.
The reservoir was initially taken out of service on August 28, 2017, with urgent repairs to the east cell of the project occurring from September to November 2017. After the east cell was secured, work commenced on a full renewal of the west cell. West cell renewal included replacing nearly 10 acres of liner and 10 acres of cover material. In addition to a new liner and cover, a pumping and dewatering system was installed to prevent rainwater from pooling on top of the reservoir cover. Now that the west cell is returning to service, PWSA contractors can drain the east cell and begin its full renewal as well.
The entire Lanpher Reservoir renewal project, which includes improvements to the walls surrounding the reservoir, will cost approximately $12.5 million. Depending on weather conditions, the Authority expects the work to be completed by the end of 2018. Improvements to the gatehouse and the construction of new metering and chemical addition facilities are planned for 2019.
