GC20240819a - Gilpin County Water Infrastructures - Dory Lake Pump Station

Gilpin County operates a pump station in Dory Lake to augment Ralston Creek flows, when determined by the State Water Commission, out of Dory Lake and into nearby Ralston Creek to maintain obligations to senior water rights. The current system is at risk of failing due to the submerged pumps in Dory Lake nearing the end of their life cycle.  Instead of replacing the submerged pumps in-kind, the new construction will include installing a new submerged intake to include an air backwash cleaning system to allow for cleaning without divers. Two new pumps and necessary piping will be installed along the shoreline within a premanufactured pump enclosure.  The new intake from the lake will be plumbed into the premanufactured pump enclosure and the outlet will tie into the existing discharge line. Removal and upgrading of electrical fixtures will be required.   
Firms with experience in pumping facilities for municipal and/or commercial infrastructure will be best suited for this project. A proposal to provide for removing the existing pumping and electrical equipment and installing intakes, piping and premanufactured pump enclosure (already purchased) will be required.
