The Pittsburgh Water and Sewer Authority has received permission from state officials to begin adding orthophosphate to treated drinking water.

The chemical has been shown to reduce corrosion from lead and copper water pipes.

The authority says it needs to install equipment at all four pumping stations to add the chemical. That should be complete in late summer.

In addition, the PWSA will conduct a large scale flushing program to prepare the water distribution system for the new treatment.

More details to be released in the coming weeks.
