• Water Treatment

    CWI is a leading constructor of water treatment facilities with no fewer than 30 facilities to our credit. We are one of the leading installers of GAC (Granular Activated Carbon), Iron-Manganese and Arsenic filters in the Central and Northern California area. We have also constructed ground water extraction and treatment facilities at Mather Field, McClellan AFB and Castle AFB. These facilities included ground water extraction wells, conveyance pipelines, GAC treatment and air scrubbers as well as chemical injection and storage.


    CWI recently completed the Oakwood Water Treatment Plant, which consisted of a water storage tank, backwash tank, arsenic and iron-manganese filter system, booster pump station, standby diesel generator and controls.
