Sample Water Resources Projects - Continued 1L - a: Z,,z! - - -- �w ' C�� 1 Plum Creek Regional Reuse Master Plan, Castle Rock, CO The Plum Creek Wastewater Authority operates a reuse system to supply irrigation water to two golf courses near Castle Rock, Colorado. The authority's board of directors decided to consider expanding the system to consolidate all water reuse in the service area. Boyle Engineering was retained to update the regional reuse system master plan to meet this goal. Boyle assessed the existing reuse system, and then estimated supply and demand of reuse water through 2020 for each entity in the Plum Creek Wastewater Authority. Estimated reuse demands focused on irrigation of large turf areas, including existing and proposed golf courses, parks, street landscaping, schools, and cemeteries. Improvement alternatives included analyzing seasonal storage sites and distribution system layouts with a hydraulic model of the proposed layout. A regional master plan document was then prepared. Pre - Design and Comparative Cost Estimate for Denver Basin Well Field Denver Water supplies potable water to over 1 million customers throughout the Denver Metropolitan area. With over 600 million gallons per day of water treatment capacity, Denver Water has historically relied on surface water for virtually all of their raw water supply. A heightened awareness of the vulnerability of water systems to service disruptions combined with record dry conditions in all of the watersheds supplying surface water to their system is prompting Denver Water to investigate the substantial supplies of ground water beneath their boundaries. These supplies would be reserved for emergency use only, such as in the event of a catastrophic failure of the potable supply system or for use during an extended severe drought. Denver Water has retained Boyle Engineering to assist in this significant undertaking. The project involves the conceptual design and cost analysis for over 100 wells at up to 40 sites throughout the metropolitan area, including tie -ins to Denver Water's existing potable distribution system. The project includes well -head treatment, and collection and distribution system engineering, cost and economic analyses and GIS services. Rabbit Ears Project Water Rights Transfer Analysis The Colorado River Water Conservation District engaged Boyle to investigate the feasibility of transferring the water rights of the Rabbit Ears Project to its newly completed Wolford Mountain Reservoir. During the 1940's and early 1950's, the U.S. Bureau of Reclamation conducted a reconnaissance investigation of the Rabbit Ears Project, which consisted of a 22,500 -af storage facility on upper Muddy Creek, an east side and a west side lateral canal, and numerous diversions from tributaries intercepted by the laterals.
