Title

City of Rialto Waste Water Treatment Plant Master Plan / Expansion

Description

As proposed in the Wastewater Treatment Plant (WWTP) Master Plan, the capacity of Plant 5 would be doubled by duplicating each major piece of equipment. The WWTP currently processes between 7 mgd and 12 mgd. The proposed expansion would increase the rated capacity of the plant to 16 mgd. This operational redundancy is critical to the City of Rialto's ability to perform maintenance to prevent equipment failures that could result in capital replacement. As part of the Proposed Project, Plants 1 through 4 would be decommissioned in place and later removed. In addition, new high efficiency filters and an ultraviolet (UV) disinfection system would be added. The replacement of plants 1 through 4 along with the new tertiary treatment equipment would change the hydraulic profile of the plant and allow the plant to operate by gravity without the need for booster pumping. The proposed expansion and modernization would accommodate approved projects and the projected growth of the City General Plan. The expanded facility would operate more efficiently, use less electricity, and would require less maintenance than what is currently required to maintain the older Plants 1 through 4.
