From the Castle Rock News Press (Rhonda Moore):
Years after launching an effort to plan for a long-term source of renewable water, Castle Rock put out an invitation to hear from water providers that might be able to compete with the Water, Infrastructure and Supply Efficiency program, long touted as the solution to meet the needs of Castle Rock and several south-metro area municipalities.
Among the water providers that submitted bids were Renew Strategies, headed by former Gov. Bill Owens; Stillwater Resources, which acts as a broker to match providers with municipalities like Castle Rock; and United Water, which serves public water districts such as the East Cherry Creek Valley Water and Sanitation District and the South Adams County Water District.
WISE, a project from the South Metro Water Supply Authority, was not among the providers that responded to the request for proposal. WISE has long aimed to buy its water from Aurora and Denver and store it in the Rueter-Hess reservoir. The Army Core of Engineers earlier this year notified Rueter-Hess officials that the plan violates a provision of the reservoir’s federal permit, and town councils from Aurora and Denver have yet to approve a proposal for the WISE project.
The responses included a proposal from Renew Strategies to acquire underground water from the Lost Creek Basin for between $23,000 and $24,000 per acre foot, plus infrastructure costs of up to $75 million; Stillwater’s option to purchase 4,000 acre feet of Boxelder farm water rights for about $21,000 per acre foot; and United Water’s proposal to sell South Platte surface water to Castle Rock for $23,850 per acre foot, which includes about $9 million in infrastructure costs.
