Lewis & Clark will have various water storage facilities in all three states at locations throughout the System.

The first storage project involves a three million gallon composite water tower along 85th Street on the southern edge of Sioux Falls.  A $5,040,000 contract was awarded in July 2009 to Landmark Structures of Ft. Worth, TX.  The tower will be 184' high and the bowl will be 116' in diameter.  Both Lewis & Clark and the City of Sioux Falls needed a 1.5 million gallon tower in the same area.  Instead of building two 1.5 million gallon towers, an agreement was reached to build one 3 million gallon tower.  The tower is owned and operated by Lewis & Clark, but Sioux Falls is paying half of the cost and will have access to half the storage capacity for its own use.  Construction started in October 2009 and the deadline for substantial completion is November 2011.

Lewis & Clark's primary storage facility is located at the intersection of 467th Avenue and 270th Street, a couple miles northwest of Tea, SD.  It includes two 7.5 million gallon above ground reservoirs.  A $9,505,800 contract for both circular pre-stressed concrete reservoirs was awarded in August 2009 to NATGUN, headquartered in Wakefield, MA.  Construction began in November 2009 and the deadline for substantial completion is October 2011.
