This powerpoint presentation begins by providing a brief overview of the City of Clewiston, Florida. Project background includes the following: previous water source - surface water from Lake Okeechobee treated by U.S. Sugar; major expansion for U.S. Sugar; surface water issues - taste and odor with algae blooms, inconsistent water quality, THM's and HAA's can approach MCL's, reliability issues associated with drought, and SFWMD control of lake levels, The solution was to use reverse osmosis (RO) to treat the Floridan aquifer. Plant design concept, construction, project cost, and startup and performance testing are all covered. Presentation conclusions indicate the following: detail design was completed in 10 months and the WTP was constructed in 2 years; total construction cost of $20.2 million included the wellfield, the water treatment plant, and the deep injection well; change order was less than 0.5% of the construction cost; plant was commissioned and performance testing was completed in Jan 2008; and, the plant met all the specified performance requirements (rated capacity and water quality). Includes tables, figures.
