Re: WalMart Revised STEP Tank Review #1
Here are my thoughts on this proposal -------
The addition of a 5000 Gal. pump tank will lengthen the detention time in the system. This would certainly help with the problem of pump screen plugging, however, with the amount of
solids currently entering this tank, and the fact that this volume of solids will remain in the holding tank, as it currently does, I do not believe that we would see much of a difference
in pumping (sludge removal) frequency.
I do not think it would be in the cities interest to except this “fix”
