Castle Rock Water’s long-term goal is to provide a sustainable, reliable and renewable water supply for all of Castle Rock’s citizens and businesses. As part of this water supply plan, the Town of Castle Rock purchased surface water diversions, pumping and storage facilities located on Plum Creek near the Town of Sedalia. The diversion point is downstream from the confluence of East and West Plum Creek, which will allow the Town to make full use of water rights, including reusable supplies and native supplies owned in East and West Plum Creek. Existing facilities include a diversion structure, two pump stations and a storage reservoir, Castle Rock Water Reservoir No. 1 (CRR1-240 acre-feet capacity). The diversion structure provides for controlled diversion of water from Plum Creek to the Plum Creek Pump Station, which delivers water to CRR1 and to the Ravenna Pump Station (RPS). Construction of a new Plum Creek Diversion Pump Station (PCDPS) is in progress, which will replace existing Plum Creek Pump Station, and pump raw water from Plum Creek to CRR1 and from CRR1 to Plum Creek Water Purification Facility (PCWPF). In accordance with the Water Resources Strategic Master Plan, Castle Rock Water is planning to construct Castle Rock Reservoir No. 2 (CRR2-1,130 acre-feet capacity) immediately east of CRR1. This new reservoir will help Castle Rock Water to accommodate daily high demands during summer months in the coming years and as an additional storage vessel for those times when Castle Rock’s junior surface water rights are in priority.
