This Cooperative Agreement award from the U.S. Department of the Interior's Bureau of Reclamation under the Water Recycling and Desalination Construction Programs (CFDA 15.504) provides $94,464,803.17 to the City of Pismo Beach to increase groundwater recharge and improve groundwater quality in the Central Coast Blue region.

The funding will support the design, permitting, and construction of an Advanced Water Purification Facility, conveyance infrastructure, monitoring wells, and injection wells. This will enable the injection of advanced purified water into the groundwater basin to prevent seawater intrusion and provide a new, locally controlled, drought-resistant water supply. Key project components include environmental documentation, engineering design services, construction of the water treatment facility and supporting infrastructure, and facility startup. This investment aims to address water supply reliability challenges in the region through water recycling and advanced water purification technologies.

Public purpose: central coast blue will increase groundwater recharge and improve groundwater quality through the design, permitting, and construction of an advanced water purification facility (awpf), conveyance infrastructure, monitoring wells, and injection wells to inject advanced purified water into the basin to prevent groundwater contamination caused by seawater intrusion. The project will provide communities with a new, locally controlled and drought-resistant water supply by using a resource that is currently discharged into the ocean. The project will construct an awpf that utilizes a process train consisting of ultrafiltration, reverse osmosis, and ultraviolet advanced oxidation process to treat wastewater to the required level of quality for groundwater injection. The awpf will be located in grover beach at the south end of huber street. This site is located between the pismo beach waste water treatment plant (wwtp) and the SAN louis obispo county sanitation district wwtp, along the pismo beach outfall pipeline. Brine and other residuals generated during project operations will be discharged to the existing ocean outfall.a recycled water production potential of 4,390-acre feet per year was estimated by taking the average of the monthly flows and the estimated recovery rates through advanced treatment. Groundwater modeling indicates the yield for this project will have a 100144% benefit from each acre feet of water injected into the basin. The estimated annual recycled water yield will be twice as much as the central coast blue partners existing groundwater entitlement. More groundwater modeling is being performed to update and improve estimates of water yield from the project after injection.phase 1 requires up to five injection wells and phase 2 will require up to an additional two injection wells for a total of up to seven wells. Groundwater will continue to be extracted by the northern cities management area agencies using their existing production wells.activities to be performed:objective 1: contractual support for program planningobjective 2: contract for environmental documentation and permitting servicesobjective 3: contract for program management, permitting, and final designobjective 4: contractual support for infrastructure constructiondeliverable(s) and expected outcome(s):OBJ. 1 outcomes: engineering planning and design services for program planning tasks, including groundwater modeling design, construction and data collection for a test injection and monitoring well environmental documentation and environmental permitting support permitting strategy support establishing technical basis of design pilot plant planning studies and program management.OBJ. 2 outcomes: environmental consulting services to prepare ceqa and nepa environmental documentation for program facilities.
