Water treatment residuals are generated by the drinking water treatment processes at the Division of Water's (DOW) three water plants: Hap Cremean Water Plant (HCWP), Dublin Road Water Plant (DRWP), and Parsons Avenue Water Plant (PAWP). These residuals require handling, management, and beneficial use, or disposal. The City currently transfers the liquid residuals from HCWP and DRWP to the McKinley Avenue Quarry (MAQ) for disposal via sludge lines. Historically, the City has also hauled and disposed residuals from the PAWP lagoons to the MAQ.
Based on studies performed by the DOW and its consultants, the MAQ has limited remaining service life under the current disposal rates of residuals. The DOW is seeking to improve the sustainability of its current residuals management methods by moving away from a disposal-based operation to one that is entirely, or substantially, based on beneficial use. This project is an effort to reduce the DOW’s long-term reliance on utilizing the MAQ for residuals disposal.
Under this CIP, the DOW will pursue the design and construction of a dewatering system located at the MAQ. The system design is anticipated to begin in spring 2023 with construction commencing fall 2023 and completing in 2026.

Summary: This project will replace nine existing raw water pumps with new vertical turbine pumps at three of the collector wells, providing a reliable raw water source to the PAWP, make use of the existing assets and maintain the current approved capacity.
This project will replace nine existing raw water pumps with new vertical turbine pumps at three of the collector wells (CW-101, 104 and115). The pumps being replaced were the original raw water pumps for the water plant constructed in early 1980's. This puts the pumps at almost 40 years old which is well beyond the typical life span of these pumps which is 15-20 years.
If no action is taken, the pumps will continue to suffer the same reduced performance and physical deterioration that was observed in the pumps removed from Collector Well 103. Replacing the pumps is the only way to continue to provide a reliable raw water source to the Plant; making use of the existing assets and maintaining the current approved capacity.
