The City is seeking a contractor for expansion of the existing wastewater treatment plant (WWTP) and effluent conveyance system upgrades. The current effluent pump station does not have the capacity to pump all the way from the WWTP to the discharge point at the golf course ponds. The City must utilize a secondary pumping station (i.e. irrigation pump station) on the WWTP which has limited storage capacity, challenging the City's ability to move treated effluent out of the plant. In addition, the influent (bottom of the hill) lift station also requires various improvements. The scope of work consists of the following: • Installation of upgrades to one existing pump station, including, but not limited to: modifications to the wet well, pumps, piping, valves, electrical and controls, SCADA, and miscellaneous appurtenances. • Installation of upgrades to one existing sanitary sewer lift station, including, but not limited to: modifications to the wet well, pumps, piping, valves, electrical and controls, and miscellaneous appurtenances. • Installation of approximately 10,400 linear feet of 12-inch PVC effluent water main and abandon in place existing 6-inch and 8-inch pipe to Blackjack 1 effluent storage pond. • Installation of an odor control system and rehabilitation of miscellaneous appurtenances at the headworks. (BID ADDITIVE ALTERNATIVE 1). • Installation of approximately 60 linear feet of 12-inch PVC sewer main replacement with manhole installation. (BID ADDITIVE ALTERNATIVE 2).
