In April 2019, the Pittsburgh Water and Sewer Authority began adding orthophosphate to reduce lead levels in drinking water. Orthophosphate is a food-grade additive that forms a protective barrier between lead pipes and the water flowing through them. Two of the four distribution points for orthophosphate are in Highland Park.
Progress & Status
In April 2019, we completed the construction of two small buildings in the vicinity of the Highland Park Membrane Filtration Plant (MFP) along Reservoir Drive. These buildings store and distribute orthophosphate to our drinking water. Orthophosphate is a food-grade additive to reduce lead levels in the 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.
