Document Description
IRWD is proposing to construct a new filtration facility that will improve the quality of the recycled water transmitted from the San Joaquin Reservoir (SJR) by reducing algae/detritus concentrations. 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 square feet. 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. In addition to the new filtration facility and associated pipeline, 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. The operation of the proposed Project would be conducted remotely, and there would not be any full-time dedicated staff at the SJR site.
