Background/Discussion
The 6th Avenue sanitary sewer pump station is the third largest station in the sanitary collection system with nearly 35% of the City’s sewage passing through this station.
The wastewater entering the pump station is screened for solids and debris. This removal process protects the pumps from clogging and limits the potential for damage. Larger stations, like 6th Avenue, utilize a mechanically operated trash rack to clean the screens.
The pump station still has the original bar screen units constructed in 1992. This project will replace the trash rack system which has reached its service life limit. The newer technology of a modern trash rack will provide reliable removal, handling, storage, and disposal of the screenings.
The project will include the necessary modifications to the screenings room and electrical controls to accommodate the new system.
Supervisory and process control panels modified in 1992, with portions dating back to the early 1980’s, will be removed and replaced.
This project is included in the FY20 CIP and includes a budget of $600,000 in sales tax funds.
