IFB-16041A - PUMPING OF SAND/OIL TANK SEPARATORS

Summary of Specifications:
Denver Water has a number of sand/oil separators and waste water holding tanks at various facilities in and outside the metro area. The tanks vary in size and contain non-hazardous waste water resulting from pressure washing vehicles, snow melt or treated water system drainage. The waste material must be transported to an approved waste water treatment facility for disposal. The tanks are pumped on an annual or semi-annual schedule, but often the tanks will reach capacity before the schedule date, in which case they are pumped accordingly. The holding tanks range in size from 850 to 5,000 gallons in capacity. Cleaning operation may also involve vacuuming drainage troughs inside the facilities. The Board is soliciting Bids for the pumping of sand/oil separators.
