The San Diego County Water Authority planned to build a new water treatment plant
(WTP) in Twin Oaks Valley north of the City of San Marcos, California. The Authority
decided to use the Design Build Operation (DBO) approach to procure a 100 million gallons
per day treatment plant. This study was focused on identifying the source water quality for
the new plant, developing treated water quality goals, and selecting treatment processes
for the proposed WTP. A new and innovative approach based on the US Environmental Protection Agency's "Water
Treatment Plant (WTP)" simulation software was used to conceptually determine the
process train for the benchmark treatment plant. Two benchmark treatment trains were
considered: a conventional train with intermediate ozonation; and, a
membrane train with granular activated carbon. The Authority would use these
benchmark trains as the standard to rate the proposed WTP systems by various DBO
teams, during the selection process.
This paper describes the process of raw water quality analysis, selection of treated water
quality goals, selection of the unit processes and operations, and selection of
recommended chemicals for the benchmark plants. Includes 11 references, table, figures.
