The design of the Los Angeles Aqueduct Filtration Plant calls for pretreatment with ozone to aid in flocculation, to control tastes and odors, to reduce the production of trihalomethanes, to serve as a disinfectant, and to aid in the removal of turbidity. Specifications for the ozone system allowed bidders to choose among several alternatives and postponed the final design of the building housing the ozone system until the equipment has been selected. The bid documents for the ozone system required that specific date be supplied along with bids to ensure a cost-effective facility over a life cycle of 20 years. Experience with ozone systems of comparable size was also required. It is estimated that this unusual bidding procedure resulted in a cost savings for the city of Los Angeles of more than $5 million.
