How much of an overall pressure increase took place?
Pennsylvania American Water raised the water pressure system-wide by an average 25 pounds per square inch (psi). In late 2008, the company increased the pressure approximately 11 psi in the affected areas listed above, with the final phase gradually increasing the pressure the remaining 14 psi. In June 2008, the company raised pressure at its Silver Spring Water Treatment Plant, but the change affected only the areas of Silver Spring, Hampden, and East Pennsboro Townships north of the Conodiguinet Creek, and one neighborhood of Camp Hill Borough near Holy Spirit Hospital.
