Westside Pump Station Enhancements

About the Project

The Westside Pump Station Enhancements project will include installation of electrical and plumbing utilities, providing the required electrical power and water needed for new infrastructure on the existing Westside Pump Station site. The new infrastructure, an odor dosing station, will be constructed from October 2023 to January 2024. Service will commence in spring 2024 with deliveries of non-hazardous magnesium twice a week. Multiple safeguards are in place to prevent any spills including double insulated tanks. Magnesium hydroxide works by increasing the pH of the treated wastewater, which safely reduces odors.

Location: Westside Pump Station at 3112 Yellowtail Drive in Rossmoor

Why Is This Infrastructure Needed?

This project is critical to ensuring OC San’s infrastructure is optimized for odor mitigation across its service area. OC San has an odor control plan for the entire collection system, and this project works as part of an interconnected infrastructure system to ensure operations of this essential service do not create a nuisance to customers.

Schedule

Construction is scheduled from Monday through Friday from 8 a.m. to 4 p.m.

• Phase One: Construction from October 2023 to January 2024
• Phase Two: Tank Installation to begin in spring 2024
• Phase Three: Weekly odor control solution deliveries to begin spring 2024

What to Expect: 

During phase one, you can expect an increase in construction vehicle traffic and noise as work is occurring.
