March 19, 2001--To maintain its momentum as the fastest growing municipality in Missouri, the City of O'Fallon, approximately 30 miles west of St. Louis, has awarded Black & Veatch a contract to design new water supply system and treatment facilities. Until now, the city has relied on seven deep rock wells with aeration, softening, and chlorination.
By this fall, B&V will complete the design of six new wells in an alluvial aquifer, a new 6 million gallon/day filtration plant, a transmission main connecting the wells and the plant, and a new 500,000-gallon finished water storage reservoir. The new treatment plant will use reverse osmosis and nanofiltration to soften the groundwater supply.
"We chose membrane technology for its ease of capacity expansion, adaptation to remote operation, and resultant high water quality, as well as the fact that it doesn't produce water-softening residuals," said O'Fallon Project Manager Monte Ellis. "Black & Veatch has considerable experience in applying this advanced technology, which will enable us to comply with current and future water quality regulations."
Construction of the $13 million project is scheduled to begin late this year, and O'Fallon's new water system is expected to be operational by early 2003.
