Aurora, Colorado Project Selects Siemens Equipment

Siemens Water Technologies has received a $2.9 million award to supply equipment for the new 50-million-gallon-per-day (mgd) Aurora Reservoir Water Treatment Plant, which is part of the Prairie Waters Project for the city of Aurora, Colo.

Water from the South Platte River will be piped 34 miles to the water purification plant, where it will undergo softening, filtration, ultraviolet light oxidation, and activated carbon adsorption before being distributed. The softening equipment supplied by Siemens includes four 12.5-mgd Contrafast high rate sludge thickening clarifiers for installation in concrete basins. The company also will supply 70 ESSD stainless steel washtroughs for placement in media filters and activated carbon adsorption cells.

 Both of the city's existing water treatment plants received the Phase 3, Director Award from the American Water Works Association Partnership for Safe Water, and the new plant is designed to continue to meet this commitment to water quality. The first phase of the new plant is scheduled for startup in 2010.
