Document Description
The Project includes the proposal of a treatment process that is a direct expansion of the Eastside Water Treatment Facility (EWTF). This includes cartridge filter pretreatment to prevent solids loading on the Granular Activated Charcoal (GAC) system, eight additional GAC vessels to be configured in a lead-lag setup for removal of 1,2,3- trichloropropane cartridge filters on the GAC effluent to protect the Ion Exchange system from media carryover, and the addition of an Ion Exchange System for removal of nitrate. All demolition and construction associated with implementation of the EWTF expansion will take place at the EWTF site. The existing generator pad, concrete waste vault, highlines, and concrete pads will be demolished. A new generator pad will be constructed, and the existing generator connection box will be relocated. A new Ion Exchange system building will be constructed north of the existing treatment plant and new GAC vessels will be installed west of the existing GAC system. Two existing GAC vessels located near the southeast corner of the EWTF site will be relocated to this portion of the site. Existing brine waste tanks located under the treatment plant canopy will be repurposed for the Ion Exchange system process. Brine waste will be conveyed from the EWTF site via the proposed Brine Pipeline to the
Inland Empire Brine Line.
The Brine Pipeline component will consist of dual six-inch diameter pipelines that will convey brine waste from the EWTF to the Chino I Desalter Treatment Facility. The dual pipelines will be constructed adjacent to each other with an approximately six-inch separation between the pipelines. The portion of the dual pipelines constructed within the Euclid Avenue right-of-way will be encased in a 12-inch diameter steel casing.
