The San Diego County Water Authority (Water Authority) currently imports water from the
Metropolitan Water District of Southern California to supply the needs of its 24 member
agencies in San Diego County. The Water Authority has initiated the new Twin Oaks Valley
Water Treatment Plant (TOVWTP) project as part of a $3.2 billion Capital Improvement
Program to meet the immediate need for additional regional treatment capacity.
The facility is designed to produce a base flow of 100-MGD of high quality drinking water with
submerged ultrafiltration (UF), ozone, biological carbon contactors and chloramination while
addressing increasingly stringent drinking water regulations, greater consumer demand for
aesthetically pleasing tap water and diminished source water quality.
This large-scale facility will establish industry benchmarks by incorporating technological
innovation and automated process control to optimally leverage operations staffing and water
quality monitoring, environmental value and sustainability (e.g., minimizing residuals and
energy consumption), and addressing public concerns (taste and odor, preserve green space,
reduce plant footprint and public impact). As such, TOVWTP will serve as a landmark facility
that meets the Water Authority's drinking water needs while exerting minimal local impact.
This paper covers the unique design, construction and schedule issues associated
with a large-capacity facility requiring uninterrupted production of 100-MGD of drinking
water. A key project challenge is meeting a fast-track delivery schedule. CH2M HILL must
design, permit, construct, and commission the facility in less than 30 months (by April 15, 2008).
Once commissioned, CH2M HILL will be responsible for operations for a period of 15 years.
This information will be of interest to municipalities, utilities, regulators, and consultants at all
staff levels who are interested in how a large capacity, state-of-the art drinking water facility is
implemented on a fast-track schedule using an alternative procurement method. Includes tables, figures.
