Denver, Aurora and the South Metro Water Supply Authority make the WISE project official


From The Pueblo Chieftain (Chris Woodka):

The Water Infrastructure and Supply Efficiency partnership between Denver, Aurora and the South Metro Water Supply Authority was announced Tuesday. The partnership could reduce pressure on agriculture in the South Platte and Arkansas river basins and the need for diversions from the Colorado River.

“I think it’s a step in the right direction,” [John Stulp, water adviser to Gov. John Hickenlooper and chair of the Interbasin Compact Committee] said. “I think it’s a unique way to share water and infrastructure. From what I understand, there is built-in drought protection. There are efficiencies and redundancies that can take pressure off ag communities.”[…]

The WISE partnership will improve South Metro water supplies while maximizing the water resources and infrastructure of Denver and Aurora. The agreement is in a 60-day review period and must be approved by all of the parties. South Metro represents 15 municipal water suppliers in Douglas and Arapahoe counties…

The backbone of the partnership is Aurora’s $659 million Prairie Waters project that allows return flows from treated wastewater in the South Platte River to be recaptured and treated. In Colorado, water from transbasin diversions and some water obtain through water rights transfers can be used to extinction. Aurora has built the first phase of Prairie Waters to treat up to 10,000 acre-feet of water per year, but it can expand to 50,000 acre-feet per year…

There would, however, always be seasonal capacity in the Prairie Waters project to provide additional water for users in the metro area, because the project is scaled to meet peak demands, [Mark Pifher, director of Aurora Water] said. The proposed agreement will sell treated water to South Metro for $5.38 per 1,000 gallons, with minimum guaranteed deliveries of 5,000 acre-feet per year beginning in June 2013. That works out to about $8.76 million annually. After 2020, the amount would increase to 10,000 acre-feet per year. Eventually, systemwide improvements could provide as much as 60,000 acre-feet to South Metro, Pifher said. Denver also would gain a new water supply through recycling its flows through Prairie Waters. In addition, South Metro water users would agree to fund improvements to Denver Water and Aurora infrastructure with $15.4 million over eight years, which is the equivalent to a tap fee. The money would go for interconnections between the Denver, Aurora and other systems. The agreement also includes a $412,000 connection between East Cherry Creek Village and Aurora.

The deal, which would pay Denver and Aurora water utilities $17.4 million a year, is one of the first of its kind in the nation. It lets water agencies that often compete for resources share without merging, and sustain more people without diverting more water from over-subscribed Western Slope rivers. Environmentalists and state leaders swiftly praised the emerging arrangement.

“This type of water-sharing agreement is a critical step toward bolstering water supplies in the southern metro area while better utilizing water resources in Aurora and Denver,” Gov. John Hickenlooper said…

Denver and Aurora would funnel as much as 1.6 billion gallons of purified water a year to suburbs by 2013, increasing to as much as 3.2 billion gallons by 2020. Engineers say necessary new pipelines and hook-ups eventually could send as much as much as 19.5 billion gallons — 60,000 acre-feet a year — to the suburbs. Denver Water, Aurora Water and 13 participating suburbs would have to replumb before the first water could be delivered — which could bloat water bills for residents of Castle Rock, Parker and other communities. Those communities already need more than the maximum amount of water deliverable under the current 22-page contract, said Charles Krogh, past president of the South Metro Water Supply Authority, who represented suburbs through lengthy negotiations. “Our demands now are about 70,000 acre-feet annually,” Krogh said. “This proposal allows us to get in the game for renewable water supplies.”[…]

The replumbing would include a $412,000 hookup between Aurora pipes and an East Cherry Creek Valley pipeline and storage of water in Parker’s new Rueter-Hess Reservoir. To receive water, south metro suburbs would have to install additional pipelines “to connect ourselves all up,” at an estimated cost of $80 million, Krogh said…

South suburbs, if they approve the contract, would be obligated not to divert water from Colorado’s Western Slope.

Aurora Water, Denver Water and the South Metro Water Supply Authority have developed a water delivery agreement that, if approved, would provide SMWSA with up to 5,000 acre-feet of water per year by June 2013, increasing to 10,000 acre-feet per year by 2020 as additional pipeline and other infrastructure are built. SMWSA represents 15 water providers in Douglas and Arapahoe counties. The amount of water delivered annually could eventually expand to up to 60,000 acre-feet per year…

The new supply of fully treated water from Aurora’s state-of-the-art Binney Water Purification Facility will provide much welcomed relief to SMWSA and its members, who have been looking for ways to reduce their reliance on non-renewable underground aquifers, Baker said in a release. It also will reduce the need for the SMWSA members to pursue agricultural water rights in the South Platte River basin in the near term.
