To achieve the treatment optimization goals of the U.S. Environmental Protection Agency's Partnership for Safe Drinking Water and comply with the Pennsylvania Department of Environmental Protection's filter performance evaluations, Aqua‐PA maintains an aggressive, proactive filter inspection program for all of its treatment facilities. The inspections – including media sampling, sieve analysis, auxiliary wash maintenance, backwash evaluations, and media floc‐retention tests – help Aqua‐PA meet the challenges of maintaining older facilities. Challenges presented by an aging treatment plant in southeastern Pennsylvania are discussed, along with upgrade options including underdrain replacement and air scour system, system installation, enchanced performance, and a successful partnering arrangement.
