The Plan
ImageLewis & Clark will provide treated water to its member municipalities and rural water systems.  When completed, the System will provide safe, reliable drinking water through its members to over 300,000 people in South Dakota, Iowa, and Minnesota. Lewis & Clark's member systems will use this new source of water to either replace or supplement existing sources of supply.
Through careful engineering analysis, the Missouri River was determined to be the most viable source of water for Lewis & Clark. Utilizing a series of wells to tap into an aquifer adjacent to the Missouri River near Vermillion, SD, when completed the System will distribute treated water through 337 miles of pipeline to members in a roughly 5,000 square mile area -- the size of Connecticut. In addition to a traditional lime treatment facility, the non-looped System will also include a series of pump stations and reservoirs. The water treatment plant is located three miles north of Vermillion.
The maximum capacity from the completed system will be 45 million gallons per day (MGD) with the ability to expand to 60 MGD in the future. The 45 MGD represents less than 3/10th of 1% of the average daily flow of the Missouri River. For more information on the technical aspects of the project, see the Final Engineer Report under the Technical Information link.
Lewis & Clark will improve the quality of life for area residents by addressing water quality, supply and infrastructure problems. In addition, it will stimulate the regional economy for years to come. Besides the obvious long-term economic development opportunities for its members, Lewis & Clark will have a positive impact on the local and regional economies during construction.
After 23 years in the making, Lewis & Clark finally began delivering water to 11 of its 20 members on July 30, 2012.  Members receiving water include; Beresford, Centerville, Harrisburg, Lennox, Lincoln County RWS, Minnehaha Community Water Corp (one of three connections), Parker, Sioux Falls, Rock Rapids, South Lincoln RWS and Tea.  The schedule to connect the remaining nine members is entirely dependent upon federal funding levels.  In addition to the other two connections for Minnehaha Community Water Corp, members still waiting for water include; Hull, Lincoln Pipestone RWS, Luverne, Rock County RWD, Madison, Sheldon, Sibley, Sioux Center and Worthington.  Four of these non-connected members are in Iowa, four in Minnesota and one in South Dakota.
