The CWRWS operates its Surface Water Treatment Facility (SWTF) from Spring to Fall during high demand periods primarily associated with irrigation. It is an essential system because the Ground Water Treatment Facility (GWTF) is not able to meet the high demands of the summer months. The intake of surface water into the SWTF begins at the Raw Water Building where screens and gates keep out unwanted debris and pumps begin delivering water from the North Platte River to the Casper Water Treatment Facility (CWTF). The Raw Water Building was upgraded during the 1996 construction project and most of the equipment has not been replaced or upgraded since that time. Currently, there are pieces of intake equipment that are broken down and completely inoperable. HDR Engineering completed a Condition Assessment and Preliminary Facility Plan in 2016-2017. From this study HDR concluded that the sluice gates (no later than 2027) and traveling screens (no later than 2035) were in need of being replaced. They also recommended that an additional screen wash pump be installed for redundancy. To provide an efficient project that addresses current difficulties in operating the Raw Water Building intake system, all of the primary equipment needs to be replaced, including the sluice gates, sluice gate actuators, bar screens, traveling screens, recirculation butterfly valves, and the air scour system that cleans the bar screens. This equipment is essential for operating the high-demand summer season to ensure the regional water system’s demand by customers can be met.
