Rueter-Hess Water Purification Facility Residuals Solids Pond Expansion Project

The Parker Water and Sanitation District (PWSD, District) owns and operates a community water system that consists of a 10 million gallon per day (MGD) ceramic membrane filtration water treatment plant, known as the Rueter-Hess Water Purification Facility (RHWPF). The RHWPF treats surface water from the Rueter-Hess Reservoir (RHR). The water system provides drinking water to residential, municipal, commercial, and industrial customers located within the District’s service area.

The water treatment process includes a ballasted flocculation pretreatment system, a powder activated carbon (PAC) process, followed by ceramic membrane filtration, chlorine contact and storage. Finished water is distributed to the service area system via high service pumps and gravity. The RHWPF produces an average of approximately 1.5 MGD and 3.3 MGD of finished water during the winter and summer, respectively.

The District has approximately six acres of land available adjacent to the east side of the existing resiudal ponds that can be used to construct additional residuals handling ponds. The existing residual ponds have a bottom area of approximately 59,000 square feet (sf) and an operating depth of roughly five feet. JVA designed two additional residuals handling ponds (Ponds 3 & 4) to serve the 10 MGD plant capacity. The two additional ponds will be operated in the same manner as the two existing ponds, with manual operation of the outlet and decant structures. The project also includes ancillary improvements to the CEB waste system, addition of a third decant pump and decant flow meter and minor SCADA modifications.
