Consolidated Public Water Supply District No. C-1 of Jefferson County

District C-1 is largely a residential area with the majority of its customers working and commuting to St. Louis and St. Louis County. The boundaries of District C-1 can basically be described as the area bordered by Arnold on the north end and Pevely to the south and in between Highway 55 to the east and Highway 21 to the west. District C-1 serves over 14,819 customers in the unincorporated communities of Barnhart, Imperial, Arnold, Antonia, House Springs, High Ridge, Hillsboro, and Otto.  District C-1 distributes water purchased wholesale from the Missouri American Water Company over a 60 square mile area.

The system consists of over 371 miles of pipelines, 4 ground storage tanks with re-pump facilities with a combined capacity of 4.5 million gallons, along with 4 elevated storage tanks with a combined capacity of 1.3 million gallons, giving the District 5.8 million gallons of storage. The entire District was converted over to the wholesale water supply in October 2004.

Two of the deep wells that originally served the District are held in reserve for emergency purposes which are run and tested on a monthly basis.
