Oceanside Desalination Piloting and Feasibility Study

This 12-month pilot study operated on a coastal vertical well, producing feedwater of 18,000 mg/L TDS, with 2 mg/L iron and 1 mg/L manganese.  The City of Oceanside wanted to identify a feasible and cost effective way to add a seawater component to the Mission Basin Groundwater Purification Facility (MBGPF).  The project was to combine the existing MBGPF brackish water treatment with a nearby seawater component to maximize the use of locally available groundwater supplies.  The one year pilot testing program was launched to generate information on the proposed feedwater source.

SPI was responsible for all aspects of treatment process including development of test protocol, specification and supply of pilot equipment, complete on-site operating services, sampling, data analysis and reporting.  The treatment process performed extremely well and achieved >99% on-line time.
