R-6070A - Wemlinger Water Purification Facility Comprehensive Upgrades Program

Wemlinger Water Purification Facility (Wemlinger WPF) located at 18301 East Quincy Avenue, Aurora, Colorado is currently a direct filtration facility with short hydraulic residence time flocculation basins followed by filtration and rated for 80 MGD. Aurora Water plans to convert the facility to conventional treatment by constructing new flocculation and sedimentation basins onsite. Additionally, the conversion will require modifications to the existing drying beds to handle the additional solids removed from the raw water, and to account for the fact that most of the solids removed will be from the sedimentation basin while backwashes will still occur and will also send solids to the drying beds. Therefore, as part of the project it will include the necessary modifications to the drying beds.
