I am tasked with developing a PM program for the collection system (force mains, air releases, and sewers). I am looking to see if anyone knows if there is a "standard of care" for PM schedules? I am also interested in what other utilities have used as their parameters to develop the criteria for inspection schedules, i.e, age, size, type of pipe, etc. Tue, 06 Nov 2007 18:26:22 GMTChad
