BACKGROUND:
Water Division Updates
Cypress Water Production Facility (CWPF) and Distribution System Update Well No. 5 remains offline due to the detection of benzene and the construction project to upgrade the CWPF. The State’s Division of Drinking Water (DDW) and the Los Angeles Regional Water Quality Control Board (RWQCB) have been investigating possible sources of benzene, and information is available at https://www.lomitawater.com/news/.
In November 2023, the City pumped 0.0 acre-feet of groundwater from Well No. 5. All drinking water was supplied with imported water from West Basin MWD. In November 2023, the City imported 151 acre-feet from West Basin MWD. The monthly water reports can be found at www.lomitawater.com/oversight/water-quality-reports/.
To protect the water system, all backflow devices within the service area are required to be tested once per year. In Lomita’s water system there are approximately 160 backflow devices. In August, letters and backflow test forms were sent to the customers requiring the devices be tested and forms submitted by September 18. The City has received 100% of the test results.
The City has been offering monthly tours of the Cypress Water Production Facility. One tour was conducted in November and a total of 2 community members toured the facility.
Residents who are interested in touring the facility may sign up for a tour at https://www.lomitawater.com/water-tours/.

This project consists of abandoning a watermain that runs north and south within private properties crossing 246th Street, 247th Street, 247th Place, and 248th Street. The proposed new water main will extend from 246th Street beyond the City boundaries, looping within the City of Los Angeles right of way and along Western Avenue (which is Caltrans’ right of way), and connecting back to the City of Lomita along 247th Street, 247th Place, 248th Street and Lomita Blvd. This project consists of constructing approximately 3,300 linear feet of PVC water pipeline and appurtenances (fire hydrants, valves, services, and fittings). The existing pipeline located in private property will be abandoned. 3 Design of the project was awarded to Onward Engineering in November 2021, and design is complete. City Council approved the project and authorized release for bidding, which will take place in early 2024.

Emergency Generator
This project consists of installation of an emergency generator that will be capable of servicing the Appian Way Pump Station as needed. The design of this project was completed by AEPC Group in June 2023, and the City awarded the construction contract to Blue Ridge Mechanical, Inc.
This project consists of 1) The City directly procuring the permanent generator and load bank from Gen-Tech, 2) The City directly renting a temporary generator from United Rental and 3) A construction contract with Blue Ridge Mechanical Inc. for installation and testing. The short-term rental generator from United Rental was mobilized and included the air permit (through SCAQMD) for the rental unit. Since the Gen-Tech permanent generator was delivered in October, the short-term rental has been removed from the site.
The load bank had a longer lead time and was not scheduled to be delivered until February 2024. The City cancelled the load bank order and will have the contractor, who will provide annual maintenance, provide their own load bank. The City is working with a third party to replace rental wires between the new generator and the pump house with permanent wires.
The City has applied for and received temporary operation permit (through CARB Board) for the permanent generator. The City has contracted a third party to facilitate final inspection of the generator by the CARB inspector followed by a permanent permit. The site visit is being scheduled for the CARB Board inspector to complete the formalities for the permanent permit.
