I am looking for comparitive O&M costs for similar activated sludge plants to ours, rated at 25 to 30 MGD average flow for max month, no ammonia limits. Or if someone can point me towards an article on benchmarking, I'd appreciate it.

You may want to request a copy of budgets from similar sized utilities, larger utilities, and smaller utilities.  When you see things that don't make sense...ask.


A real thing that surprised me was how much more effective smaller utilities perform at times.  If there's a chronic problem, a small operator that doesn't want to get bothered will find a permanent solution.  Larger plant operators often say "I've got people to do that".


If you bug folks for information, reciprocate by providing a summary of your results or perhaps do a paper with your findings for the local MA.  Finally, don't forget to share it with WE&T staff too.


Good luck and sorry to be responding late!
