Many of the water treatment plants in the United States were constructed during the 1950s and 1960s and their components are approaching the end of their expected service lives. Water treatment plant managers need to know how long certain components are expected to last in order to make sound decisions about the allocation of funds. To create a successful, long-term Capital Project Schedule, the Philadelphia Water Department of Philadelphia, Pennsylvania, has begun a pilot Capital Facilities Assessment Program, which identifies inspection and testing protocols for critical infrastructure at the Department's water and wastewater treatment facilities and pumping stations. This paper discusses Philadelphia's Assessment Program and its application at the Queen Lane Water Treatment Plant.
