Renovations began on the Cal Memorial Stadium by Webcor Builders. During concrete curing operations, it became necessary to treat the water for pH adjustment. A separate system was needed to address storm water prior to discharge under the NPDES Construction General Permit.
Clear Creek mobilized a 200 gpm groundwater treatment system using tanks, filtration, and a pH adjustment system. To handle stormwater runoff, a separate 400 gpm Active Treatment System was mobilized under the CA General Construction Permit and included treatment tanks, a compliance and control monitoring module, a sand filter system, and a hydrocarbon removal system. Clear Creek provided installation and operation of both systems.
