Document Description
The new filtration facility would be constructed on an existing concrete pad that is north of the existing Flow Control Facility, which is on the north side of the SJR. The proposed filtration facility would be a single-level, above-grade structure that would total approximately 4,000 sf. Two new filtration pumps would be installed within the filtration building to pump waste washwater from the filtration building to the southern end of the SJR for disposal. The pumps would connect with a proposed concrete at-grade equalization basin, which will be located outside the proposed filtration building. A pipeline would be installed from the equalization basin into the southern end of the SJR to return the filter waste washwater. The new filtration facility will also include an enlarged electrical room, along with a hose, sink/wash basin, emergency shower, and eye-wash station. Additionally, the proposed Project includes replacing the booster pumps, located in the existing pump room of the Flow Control Facility on the southern end of the concrete pad, to accommodate the new filters. A new pad would need to be constructed for the 1,500-kilovolt ampere (kVA) transformer, required by Southern California Edison (SCE) for electrical service. Construction of the new transformer pad would require notching of the adjacent hillside to install a retaining wall. The existing 300-kVA transformer would be removed, but the existing pad would remain after Project implementation.
