The Regional Water Recycling Plant No. 5 (RP-5) Expansion Project will expand the plant’s liquids treatment capacity and construct a new solids handling facility. The liquids treatment capacity of RP-5 will be increased from 15 MGD to 22.5 MGD to support service area growth. The solids handling facility replaces the existing solids handling facility at Regional Water Recycling Plant #2 that will be within the Prado floodplain once the Prado Dam spillway height is increased, and increases the solids treatment capacity of IEUA to support expected growth in the service area. The plant will meet all regulatory requirements, utilize energy efficient equipment, and continue to provide recycled water to the service area.
