Water Treatment Plant
ImageThe water treatment plant (WTP) will provide treated water capacity of 45 million gallons per day (MGD) and is being designed with the ability to expand in the future to 60 MGD. It will be located three miles north of Vermillion, SD, along Highway 19. A total of 226 acres of farmland have secured for the site. A traditional lime treatment method will be used. The WTP is being built in three phases. Engineering services are being provided by Banner Associates and HDR Engineering. 

WTP - Phase 1:
A $20,844,000 contract for Phase 1 was awarded in July 2008 to Foley Company of Kansas City, MO. The project includes a three million gallon underground reservoir, high service pump station and electrical switchgear building. These are components of the treatment plant that are separate from the main water treatment plant building. Construction began in September 2008 and the deadline for substantial completion is September 2010. 

WTP - Phase 2:
Foley Company was also the low bidder in May 2009 on Phase 2, which includes the main water treatment plant building. With the addition of three bid alternates, the total was $64.1 million, which was substantially below the engineer's estimate. Phase 2 will provide Lewis & Clark with treatment capacity of 36 MGD. Construction began in July 2009 and the deadline for substantial completion is March 2012. At that time, it is expected Lewis & Clark will begin delivering water to the first 10 members, with the remaining 10 members connected as Federal funding allows. 

WTP - Phase 3:
Phase 3, which is planned for construction after all 20 members have been connected, will expand the water treatment plant to its originally planned capacity of 45 MGD.
