There is no intention to build a 10 million-gallon recycled water storage tank as part of any phase of the project. Reference in the EIR to this amount of storage is because the Regional Water Quality Control Board asked the City to explore different storage scenarios as part of studies and reports it requested.
Maximizing reuse of recycled water is one of the project objectives. Although availability of 10 million gallons of storage would allow for maximum reuse of the recycled water produced by the treatment facility, maximized reuse is not feasible and not needed to make the project ‘work.’ Extensive field testing and modeling of the groundwater basin indicate that there is sufficient injection capacity to dispose of the total volume of effluent from all phases of the project, assuming zero recycled water use.
The siting difficulties and expense of providing 10 million gallons of storage would jeopardize the feasibility of the project, and is not an essential part of the project. Therefore, it is not a recommended project component.
When the project moves into Phase 2 (or when it moves into Phase 3), additional recycled water storage may be considered, but would only be implemented if acceptable sites are found in proximity to areas that would use the recycled water. This may require additional environmental (i.e., CEQA) documentation, depending on the site sizes, locations, etc.
