Water Storage

Water storage in reservoirs is an essential component to operating an augmentation plan along the South Platte River. During times of free river, or when our surface rights are in priority, we can fill reservoirs, then during times of high need, release the water back to the river.  To that end, Central has constructed numerous reservoirs and gravel pit storage ponds, from as far west as Windsor, east to Fort Morgan, and south as far as Brighton. Of particular pride is Central’s Siebring Reservoir. The former gravel pit is now the world’s first slurry wall lined storage reservoir.

Constructed in partnership with Hall Irwin Construction, the unique lining made from bentonite clay allows for below grade storage with minimal groundwater interaction. This same technology is now being used around the world. Other gravel pit lined storage ponds owned by Central include La Poudre, Koenig, Nissen, JoDee, Bernhardt, 83rd Avenue and one of the largest projects.
