From The Fort Morgan Times (Marianne Goodland):
The Colorado Water Plan draws upon a decade of work by the state’s eight basin roundtables, the Interbasin Compact Committee and the Colorado Water Conservation Board (CWCB). It also incorporates information from the 2010 Statewide Water Supply Initiative, which predicted the state will have a gap between water supply and demand of about 500,000 acre feet of water by 2050, with the largest gap projected for the South Platte River Basin.
During the past year, the basin roundtables and the CWCB have held dozens of town meetings on the water plan, seeking input from citizens and organizations interested in the state’s water future. Those meetings wrapped up in April, and then the basin roundtable members went to work to develop their basin implementation plans (BIPS), that will be submitted to the CWCB at the end of July. Those plans will be incorporated into the draft Colorado Water Plan, which is due to the Governor at the end of the year. The plan is to be finalized by December, 2015.
In addition to the basin implementation plans, the state water plan will include a “framework” document that outlines the issues to be addressed. The CWCB has already released eight draft chapters of this framework document this year, with four coming out in the last month. The most recent drafts covered water quality, conservation and re-use, and alternative agriculture to urban transfers. The drafts will be updated based on input from the BIPs.
The draft on agricultural transfers focused on alternative agricultural transfer methods (ATMS) and current efforts to develop more creative solutions to “buy and dry.” The draft noted several ATMs are already in place and more are on the way. These include deficit irrigation, water co-ops, water banks, water conservation easements; and flexible water markets, which was proposed in the 2014 legislative session but failed to clear the Senate. Another ATM, farrowing-leasing, which would allow for farrowing of irrigated farmland with temporary leasing of water to municipalities, is being studied under legislation passed in 2013.
More than 1,000 emails and documents have come in to the CWCB, addressing the draft chapters. Almost half of the responses came from stakeholders in the South Platte River and Metro Denver districts.
Most of the comments received by the CWCB have come either through emails to email@example.com or through a webform on the water plan website, coloradowaterplan.com. CWCB staff responded to all of the comments, even those that might not be financially or technically feasible. One such comment said the state should cover its reservoirs with a thin membrane “similar to bubble wrap” to slow evaporation. Another suggested that the state halt all housing development along the Front Range.
A handful of comments addressed agricultural use, including responses that encourage more efficient irrigation systems and pointing out that agriculture is far and away the biggest user of water. But one commenter suggested a new form of “buy and dry.” Kristen Martinez of Metropolitan State University of Denver said the city of Denver could pay for businesses and residents to xeriscape their lawns, similar to a plan implemented by the city of Las Vegas. She also recommended the city of Denver invest in more efficient irrigation systems for farmers, as a trade-off for buying up agricultural water rights.
“…agriculture stands as the biggest water user, but farmers should not be the only ones to feel the pain of supply and demand,” Martinez wrote. “Most Denverites don’t give heed to the serious task of stewarding their water — not as a farmer must. Why aren’t local industries or municipal users being asked to sacrifice their lifestyle or adjust their operations?…can Colorado’s water plan please ask urban users to take ownership of their consumption, in addition to solving it by diverting farm water?”
Sean Cronin, director of the St. Vrain & Left Hand Water Conservancy District, chairs the South Platte River Basin roundtable, and pointed out that the South Platte and Metro Denver basin are collaborating on a joint BIP.
Cronin noted that although they are submitting a joint BIP, the two districts are quite diverse and one size will not fit all. “Water is very local!” he said recently. Feedback in the town meetings has been very different throughout the two districts. In Sterling, for example, he said the focus was on agriculture. In Longmont, people spoke about groundwater because of the well issues in the area. Denver’s focus was more on municipal conservation and recreational/environmental concerns.
So how will the two roundtables come up with one BIP, given the divergent views? Cronin said that they knew going into the process it would be difficult to address all of the different interests and cultures surrounding water. “It’s incredibly challenging to par it down to one solution that will make everyone happy,” he said. Cronin believes the draft BIP will instead reflect the diverse interests of the basin districts…
A recent presentation on the BIP by the roundtable to Colorado Counties Inc. laid out the plan’s major premise: “You can’t have conservation without storage, and you can’t have storage without conservation.” Even with the “Identified Projects and Processes” already in discussion (which came out of the 2010 SWSI), the gap in the South Platte would at best be reduced to about 100,000 acre feet of water, and many of those solutions are years, and maybe decades, away.
And that raised red flags for environmental groups, with one warning Coloradans that the BIP will further endanger the rivers of the South Platte basin…
Cronin encourages people to continue to submit comments through the South Platte Basin Roundtable website (http://cwcb.state.co.us/water-management/basin-roundtables). Public comments also will be accepted on draft versions of the plan through September, 2015, and can be submitted through the Colorado Water Plan website noted earlier.

From The Denver Post (Clayton Woullard):
After one year of operation, the Plum Creek Water Purification Facility has exceeded Castle Rock’s expectations in terms of efficiency as it plays an important role in the town’s long-term renewable water projects. The $22.6-million-dollar plant went online in April 2013, specifically to treat more ground water, as well as renewable surface water from Plum Creek. The facility is part of an effort by Castle Rock to have 75 percent of its water come from renewable sources by 2050, when the town projects it will be built out at 100,000 people. The town’s population is at about 53,000 now.
Other parts of the project are a renewable water agreement through the Water, Infrastructure and Supply Efficiency partnership (WISE) with Denver Water and Aurora Water, as well as storage of 8,000 acre feet of water in Rueter-Hess Reservoir in Parker. Castle Rock Utilities Director Mark Marlowe said the plant’s operating costs, along with the WISE partnerships, are coming in under budget.
“If we don’t do these things, we continue to be reliant on our deep water supplies,” Marlowe said.
That’s something the town and other Douglas County jurisdictions can’t afford, because well water continues to be depleted.
The WISE partnership agreement is almost complete, Marlowe said and will eventually bring about 7,225 acre feet of renewable water and 1,000 acre feet in the short term to Castle Rock. Marlowe said two contingencies must be finished by next year to get WISE water flowing: the $4 million purchase of a pipeline that will get water from Denver and Aurora to Castle Rock; and a new pipeline the town will need to allow it to begin receiving renewable water.
Marlowe said the water supply from WISE is interruptible, unlike the supply coming through the treatment facility.
The Plum Creek Purification Facility captures water from East and West Plum Creek and lawn irrigation return flows. The plant treats more than 4 million gallons of water per day but has the capability to treat up to 12 million gallons when it is eventually expanded. The plant has the capacity to bring the town 35 percent renewable water; now it’s between 12 and 20 percent renewable, depending on demand.
“It is exciting for our community that we get to use this resource,” said Karen McGrath, spokeswoman for the town.
Because the plant also treats surface water, it has different processes, including a series of racks or tubes of thousands of very thin, vertical membranes that filter the water and require regular maintenance and cleaning. Marlowe said surface water requires more treatment than ground water and necessitated the facility.
Most of the plant’s processes run automatically, so the plant only requires about two workers at any time. The system is set up with alarms and auto-correcting mechanisms.
Level 4 plant operator Ken Timm said it’s the most advanced water treatment plant he’s worked at.
“The only challenge is if something breaks,” Timm said, “and how fast can we get it repaired and what caused it.”
