Total Budget: $5,035,000
Final Cost: $4,858,198.15
Funding Source(s): Sewer Service Fund and Sewer Development Fee Fund I. Executive Summary
The existing sewer lift station on Humboldt Island (constructed in 1960) was replaced with a cutting-edge sewer lift station system. The new system included a 10’ diameter 25‘ deep wet well with increased holding capacity, valve vault, force main, and computer control system. It was coordinated in phases to accommodate residents by providing vehicle and pedestrian access to the island at all times. Final improvements such as new curb & gutter, ramps, sidewalk, paving and Landscaping were installed to transition to proposed bridge replacement.

III. Project Details
Project Description
Scope:
The scope of work consists of abandonment and demolition of an existing sewer lift station, and the installation of a new 185 GPM submersible sewer lift station and force main. The project also includes the construction of new gravity sewers, reconnection of sewer laterals, as well as curb, gutter, sidewalk, AC paving, and other appurtenances.
Purpose & Benefits:
Replacement of aging sewer lift station system, new system provides increased capacity, longer holding time during a power outage, state-of-the art communication control system, better accessibility during emergencies and routine maintenance, more efficient pumps, and a reduction in maintenance costs. Includes off street staging area for temp generator back up, eliminating the need for temporary lane closure, minimizing impact to residents Start Date: August 5, 2024
Substantial Completion: July 31, 2025
Final Completion / Closeout : December 3, 2026

Change Orders Summary:
Number of Change Orders: 2
Reason(s): Pump escalation cost, additional cable needed and inclusion of a splice box due to length. Additionally, utility relocations took place requiring additional amount of asphalt grind and overlay and concrete work. Work also required the removal of a water service to allow for the grade of concrete work.
V. Long-Term Maintenance and Impacts
This station, with all new equipment and has an increase in storage that will allow for more holding time for sewage. This will allow for more response time in emergencies, creating more reliability in the station. Improved appurtenances include underground pipeline with connections under the Humboldt Bridge providing system reliability during earth earthquakes and other natural disasters.
Efficient electrical equipment for pumps will reduce power consumption, thus reducing expected costs.
Maintenance will continue as expected with the station as required by the Sanitary Sewer System Management Plan.
VI. Lessons Learned
This project was a collaborative effort between the City, Contractor, Registered Design Professionals, and Construction Management Firm all employed by the City, and sets the standard of a successful project.
VII. Conclusion
