From The Denver Post (Bruce Finley):
Suburban water authorities said the project [Water Infrastructure Supply Efficiency or WISE], designed to reduce reliance on dwindling underground water, will cost about $558 million.
U.S. Bureau of Reclamation officials said “rural water supply” funds may be available for the project, if it survives a detailed feasibility review. Congress would need to authorize the federal funding, which could decrease the bill passed on to water customers. “What we’re looking at: Is this project capable of being completed? Is the cost-benefit going to work out? Is it going to be beneficial?” Bureau of Reclamation spokesman Peter Soeth said.
Meanwhile, a crucial wastewater purchase deal with Denver and Aurora has yet to be done. How much wastewater could be diverted, and how often, remains under negotiation. The suburbs told federal officials the WISE project would deliver 5,000 to 11,000 acre-feet a year for the first five years, then as much as 37,000 acre-feet a year…
The federal rural water-supply funds could be used because suburbs with populations under 50,000 are deemed “rural,” said Mark Shively, executive director of the Douglas County Water Resource Authority. “We have very aggressively pursued this opportunity,” Shively said. “We’re now about 20 percent into the feasibility study.”[…]
Beyond pipeline construction, the proposed project involves new storage of treated wastewater in surface reservoirs and by injecting it into depleted aquifers. “We have a couple reservoirs we’re looking at,” Shively said. “Between the Chatfield and Rueter Hess (reservoirs) we have a good amount of storage.”
