City enters into agreement for groundwater treatment system

September 23, 2016

The City of Cerritos has entered into an agreement with ES Engineering regarding the groundwater treatment system for the Cerritos Civic Center parking structure.

The arsenic levels in the water discharged from the Civic Center parking structure were found to exceed regulatory limits. ES Engineering has proposed a treatment system that will route water through filtration vessels that are designed to remove arsenic prior to the water being discharged into the storm drain system.

The installation and cost of the equipment is approximately $400,000 with an annual maintenance expense of about $50,000. Under a grant program with the California Energy Commission, ES Engineering will pay for the design, equipment acquisition, installation and maintenance of the system for two years. At the end of the grant term, ES will transfer ownership of the system to the City at no charge, thus saving the City approximately $500,000 in expenses.

ES is expected to install the system and begin operation no later than January 1, 2017.
