Background/Discussion
The I-80 sanitary sewer pump station is the largest station in the sanitary collection system with nearly 75% of the City’s sewage passing through this station. Wastewater is conveyed through a force main from the pump station directly to the Water Pollution Control Plant.
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 I-80, utilize a mechanically operated trash rack to clean the screens.
This project replaced the trash rack system which had 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 included the necessary modifications to the screenings room and electrical controls to accommodate the new system.
This project was included in the FY18 CIP with a budget of $250,000 in sales tax funds and $250,000 in sewer funds.
