| Details: | SUMMARY: Equipment Recommendations Assistance DETAILS: An Engineering report has been prepared discussing options for a new intake, sand-handling pumps, pre filtration sand separation and settling pond. We evaluated options for potential new intake that would function properly year round and operate without pumping sand. According to the operator there may be a spot nearby, along the Calapooya Creek that is deep enough to utilize a convention intake design, with gravity flow into a wetwell. Also researched and recommended new intake pumps for the original first intake that can pump sandy water with out damage. Pump features, materials, recommended sizing and operational strategy are discussed. Additionally, an automatic filter installed in the raw water line prior to the WTP is recommended. Sedimentation pond is discussed, pros and cons identified, a brief schematic of required pipe and pumping equipment are also included.Completed engineering report and sent to System. ACTION NEEDED: None at this time | ||
