Title

Morro Bay Water Reclamation Facility Project

Description

The project consists of construction of the Morro Bay Water Reclamation Facility (WRF), which includes an indirect potable reuse (IPR) recycled water system and decommissioning and demolition of the existing Morro Bay-Cayucos Wastewater Treatment Plant (WWTP). In addition to the WRF, the project includes construction of administration, operations, and maintenance buildings; lift stations and pipelines to convey raw wastewater to the WRF and waste discharges of reverse osmosis concentrate and treated wet weather flows from the WRF to the ocean outfall; and a new distribution system to convey advanced treated recycled water from the WRF to new groundwater injection wells in the Morro Valley Groundwater Basin. This Addendum describes the details of several refinements to the specific locations and types of project facilities that have occurred during evolution of the design process. The locations for four potential recycled water distribution pipeline alignments and eight potential injection well sites have been defined, and a potential recycled water fill station and two new areas for potential non-potable reuse irrigation are proposed. In addition, a portion of the advanced treated recycled water produced at the WRF may be delivered for non-potable irrigation use at Lila Keiser Park and Morro Bay High School. A recycled water fill station may also be installed, either at the WRF or Lila Keiser Park, which would make non-potable recycled water available for agricultural, construction, and municipal purposes and would replace the existing non-potable water fill station at the Flippos Well at Lila Keiser Park. Lastly, groundwater extracted from the Morro Valley Groundwater Basin would be conveyed to the potable water distribution system and may undergo treatment at the City's existing Brackish Water Reverse Osmosis treatment facility, be blended with other water supply sources, or be provided directly to the potable water distribution system.
