Civiltec Engineering was selected by the City of Alhambra to improve its Sewer Lift Station #4. Located on Westmont Drive, the existing sewer lift station has caused disruptions to the City’s customers and, at times, has caused sewage backups in nearby homes due to its lack of depth. Due to condition and age of the lift station, the pumps and wet well need to be upgraded to accommodate future peak flows.
The project scope includes increasing the size and depth of the wet well to a minimum of 577 cubic feet. Meanwhile, the sewer lift station itself will be designed to pump daily flows. The team will equip the lift station with an effluent flow meter and utilize an ultrasonic level transmitter to gauge levels in the wet well on a continuous basis.
Civiltec will also replace the system’s pumps to simplify operations and ensure longevity. The existing pump station consists of two 25 horsepower self-priming pumps. The horsepower of the new pumps will increase to 40 horsepower, with 950 gallons per minute (gpm) capacity.
The upgrades will provide sufficient storage to operate the lift station correctly, while eliminating the impacts to customers.
David Byrum serves as Principal Engineer on the project, while Shem Hawes leads Civiltec’s analysis and design efforts as Project Manager. They are supported by Terry Kerger, Chris Duncan, Bed Dawadi, Gretel Ochoa, Dan Busqué, Omner Meza, Jorge Martinez, Sara Canché, and Caitlyn Padilla.
The project kicked off in Spring 2018. Final designs and specifications are scheduled to be completed by February 2019.
