Delivering Safe, Reliable Drinking Water

Over the next few years the Pittsburgh Water and Sewer Authority will be in Highland Park making improvements to our water infrastructure. 

Securing our drinking water

The first projects will help to improve the security and safety of our drinking water. These projects include installing security cameras at the Highland I Reservoir, adding UV Treatment to the Highland Park Microfiltration Plant, and applying orthophosphate, an effective method of corrosion control, that will help to reduce lead levels in tap water. PWSA will complete construction of these projects in 2019.

Highland Park Orthophosphate Project

Construction of the orthophosphate project is already underway. PWSA is constructing two small buildings in the vicinity of the Highland Park Microfiltration Plant along Reservoir Drive. These buildings will store and distribute orthophosphate to our drinking water. Orthophosphate is a food-grade additive to reduce lead levels in water. When water with orthophosphate runs through the system, it creates a coating on the inside of lead service lines and establishes a barrier between the lead pipes and the water we drink.

Modernizing our water infrastructure

The second group of projects will modernize our water infrastructure and add redundancy and resiliency throughout our drinking water system. These projects include:

  • Redeveloping the pump station located in Highland Park near Mellon Terrace.  
  • Installing a 48-inch new rising main to connect the new pump station to the Highland I Reservoir.
  • Replacing the original affluent main that carries water from the Highland II Reservoir to the pump station.

These projects are currently in their design phase. PWSA is a coordinating with the Pittsburgh Parks Conservancy, the Port Authority of Allegheny County, the City of Pittsburgh, the Pittsburgh Zoo, the Highland Park Community Council and Highland Park Community Development Corporation. 

Community members will have opportunities to share ideas and provide input into the design of these projects. PWSA will announce community meetings throughout the design process.  Please download the project sheet for more information.
