The wwtp is regional and it serves around 60,000 residents. It is a combined sewer system. The wwtp discharges into a major river that is on the 303d list (meaning that it is polluted). It does have backup generators. Secondary treatments include combined storm water overflow treatment...
What brings you to that answer? I'm a consultant working with communities so I would have to interview the people in charge of the treatment plant. Would that take a lot of extra time on top of the 80-120 hours?
Thank you
