Douglas County joins WISE project

August 31, 2014

From the Parker Chronicle (Mike DiFerdinando):

The Douglas County commissioners took an important step in helping secure the county’s water future at their regular meeting on Aug. 26.

By joining in on the South Metro Water Infrastructure and Supply Efficiency (WISE) Authority’s agreement with Denver Water and Aurora Water, the county will be the recipient of 2,775 acre-feet of water per year for a 10-year period, starting in 2016…

The South Metro WISE Authority is made up of 10 water providers that are all part of the larger South Metro Water Supply Authority. Nine of those water providers — Centennial, Cottonwood, Dominion, Inverness, Meridian, Parker, Pinery, Stonegate Village and Castle Rock — are located in Douglas County. The 10th, Rangeview Metropolitan District, is located in Aurora.

“This region has been working hard for a very long time to bring renewable water supplies into the area,” SMWSA Executive Director Eric Hecox said. “We have a legacy of developing non-renewable groundwater and the effort for many years has been to transition our current population off of groundwater as well as to provide water for future economic development, and I think this project achieves that.”

The WISE project began in 2008 as a way for members to identify processes, cost, distribution, timing, storage and legal issues relating to distributing treated reusable water return flows from Denver and Aurora for use by SMWSA water users.

The group tasked with utilizing this water is the South Metro WISE Authority. The primary purpose of the authority is to reduce members’ dependence on non-renewable Denver Basin wells and provide reliable long-term water supply for residents.

“While we often refer to the Denver Basin aquifers in a negative way, they do provide an extremely important drought reserve,” Douglas County Water Resource Planner Tim Murrell said. “By reducing Denver Basin well pumping to a secondary source rather than a sole supply, the basin can continue to be a valuable asset in times of drought.”

In 2013, Aurora, Denver and the South Metro WISE Authority finalized the water delivery agreement. As part of the deal, 100,000 acre-feet of water will go to the authority’s providers over a 10-year period.

At the time of the agreement, the authority members were only able to agree on 7,225 acre-feet per year. This left 2,775 acre-feet per year that would be lost if not claimed. Douglas County has been working with the authority members over the last year to reserve the 2,775 acre-feet per year supply for the county.

The WISE members are funding new infrastructure that will move the water from Aurora’s Binney Water Purification Facility to its end locations, beginning in 2016. Water purchased by the county, as well as by some of the other providers, will be stored at the Rueter-Hess Reservoir south of Parker.

The county will pay a $97,125 annual reservation fee through 2020; 2,000 acre-feet of water per year will be available for use and purchase by WISE members, and 775 acre-feet will be available for use and purchase by non-members.

Water Lines: Colorado needs a better water plan — Jim Pokrandt #ColoradoRiver #COWaterPlan

July 16, 2014


From the Glenwood Springs Post Independent (Jim Pokrandt):

It’s almost time for football training camps, so here’s a gridiron analogy for Colorado River water policy watchers: Western Colorado is defending two end zones. One is the Colorado River. The other is agriculture. The West Slope team has to make a big defensive play. If water planning errs on the side of overdeveloping the Colorado River, the river loses, the West Slope economy loses and West Slope agriculture could be on the way out.

This is how the Colorado River Basin Roundtable is viewing its contribution to the Colorado Water Plan ordered up by Gov. John Hickenlooper. A draft plan will be submitted this December and a final plan in December 2015. The Roundtable is assessing local water supply needs and environmental concerns for inclusion into the plan and there is plenty of work to consider in the region. But the big play may very well be the keeping of powerful forces from scoring on our two goal lines.

Here’s why: Colorado’s population is slated to double by 2050. Most of it will be on the Front Range, but our region is growing too. Mother Nature is not making any new water. We still depend on the same hydrological cycle that goes back to Day 1. So where is the “new” water going to come from? Right now, there seems to be two top targets, the Colorado River and agriculture (where 85 percent of state water use lies in irrigated fields). Colorado needs a better plan.

The Colorado Basin Roundtable represents Mesa, Garfield, Summit, Eagle, Grand and Pitkin counties. This region already sends between 450,000 and 600,000 acre feet of water annually across the Continental Divide through transmountain diversions (TMDs) to support the Front Range and the Arkansas River Basin.

That water is 100 percent gone. There are no return flows, such as there are with West Slope water users. On top of that, this region could see another 140,000 acre feet go east. A number of Roundtable constituents have long-standing or prospective agreements with Front Range interests wrapped around smaller TMDs. Existing infrastructure can still take some more water. That’s the scorecard right now. We assert another big TMD threatens streamflows and thus the recreational and agricultural economies that define Western Colorado, not to mention the environment.

In the bigger picture, the Colorado River Compact of 1922 requires Colorado to bypass about 70 percent of the river system to the state line to comply with legal limits on depletions so six other states can have their legal share of the water. Failure to do so, by overdeveloping the river, threatens compact curtailments and chaos nobody wants to see. For one thing, that kind of bad water planning could result in a rush to buy or condemn West Slope agricultural water rights.

The Roundtable has heard these concerns loudly and clearly from its own members across the six counties as well as from citizens who have given voice to our section of the water plan, known as the Basin Implementation Plan (BIP). A draft of the BIP can be viewed and comments offered by going online to http://coloradobip.sgm‐inc.com/. It is under the “Resources” tab.

South Platte and Metro roundtables #COWaterPlan update

June 30, 2014
Basin roundtable boundaries

Basin roundtable boundaries

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 cowaterplan@state.co.us 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.

Castle Rock hopes to get 75% of water supply from renewable sources by 2050

June 2, 2014

castlerock
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.”

Northwest Pipe Co. is major supplier for the Southern Delivery System #ColoradoRiver

May 23, 2014
Southern Delivery System construction celebration August 19, 2011 via The Pueblo Chieftain

Southern Delivery System construction celebration August 19, 2011 via The Pueblo Chieftain

From The Denver Post (Aldo Svaldi):

Orders at the Northwest Pipe Co. plant in Denver were drying up in 2010 when bid requests started coming for a massive water project linking the Pueblo Reservoir and Colorado Springs called the Southern Delivery System.

“The start of the SDS project couldn’t have come at a better time,” Northwest’s vice president of sales Eric Stokes said.

At a cost of $841 million, the water project is the largest the region has seen in decades. Starting in 2016, it will pipe water held in the Pueblo Reservoir to consumers in Colorado Springs, Pueblo West, Security and Fountain.

“This is our water security for many years to come, 50 years into the future,” said John Fredell, program director of the water services division for SDS.

Northwest Pipe’s Denver plant won almost all the contracts to supply 50 miles of steel pipe, and the company celebrated the completion of the last piece Thursday afternoon. Northwest produced 7,000 pieces of the pipeline, each averaging 50 feet in length and 66 inches in diameter. The orders allowed Northwest’s employment in Denver to grow from 116 full-time workers to more than 231 at the peak of manufacturing.

Of about $500 million spent so far on the project, $359 million has gone to 333 Colorado businesses, including more than 75 based in metro Denver, Fredell said.

Northwest Pipe alone received about $110 million, including $23 million spent on payroll. Given that the next closest competitor was in California, Stokes said Northwest had a distinct advantage.

“Proximity was part of it,” Fredell said.

Back in 1997, Northwest Pipe, which is based in Vancouver, Wash., acquired Thompson Pipe & Steel Co., a manufacturer with Denver roots going back to the late 1800s. For decades, Thompson built pipes in the Curtis Park area that continue to help move water across much of the state. Thompson moved its plant to a 45-acre facility at 6030 Washington St., where workers continued to convert steel coil arriving by rail car into water pipes shipped out on trucks.

Once formed, the pipes are pumped full of water and pressure-tested to ensure there are no leaks. They are moved into a cavernous ⅛ – mile-long warehouse where they are rotated rapidly while concrete is poured inside to make a lining designed to last for decades. In a third building, the pipes are primed, painted and prepared for shipping.

“It is nice to know you have finished on time,” said Jason Cheng, a welder from Westminster who joined Northwest in October to work on the SDS order.

Cheng and other workers lined up to sign the last piece of pipe, undeterred as the rain poured down Thursday afternoon. Their signatures, in white ink, quickly smeared down the bright-blue pipe.

“We want the water on the inside of the pipe, not the outside,” one person commented.

From the Denver Business Journal (Cathy Proctor):

Northwest Pipe, (Nasdaq: NWPX) is based in Vancouver, Washington. Its Denver manufacturing plant had a $110 million contract to build the project’s 50 miles of pipeline to carry the water. It was the biggest contract for materials under the project.

Northwest Pipe started making its 50-foot sections of pipe for the project, each section 66 inches in diameter, in 2011.
And the last pieces are now coming off the manufacturing line and awaiting a truck for transport to the project site.

“This is one of the largest programs that we’ve seen,” said John Moore, manager of Northwest Pipe’s manufacturing plant at 6030 N. Washington St. in north Denver.

During peak production, as many as 25 trucks a day left Northwest Pipe’s manufacturing facility.
Being in Denver meant trucking costs were less and Northwest Pipe could submit a more competitive bid for the project, Moore said.

And the project meant jobs for Northwest Pipe, which ramped up to 231 people during peak production, from a low of 116 people prior to work on the project, said John Moore, the plant manager. The company currently has 131 people on staff.
Northwest Pipe, which supplies pipes to carry water and waste water, has delivered pipes to other big water providers, including Denver Water and Aurora.

The Southern Delivery System has been a long time coming

May 12, 2014
Southern Delivery System route map -- Graphic / Reclamation

Southern Delivery System route map — Graphic / Reclamation

Here’s part one of an in-depth look at the Southern Delivery System from John Hazlehurst writing for the Colorado Springs Business Journal. Click through and read the whole article. Here’s an excerpt:

Contending that the denial [of Homestake II] had been arbitrary and capricious, the two cities [Aurora and Colorado Springs] appealed the decision to the courts. In a comprehensive description of the city’s water system and possible future sources of supply given to City Council in 1991, CSU managers said that “extensive litigation is expected to continue.”

Denied by the Colorado Court of Appeals and the Colorado Supreme Court, the cities appealed to the U.S. Supreme Court, which declined to hear the case.

City officials were stunned. They couldn’t believe that a coalition of Western Slope “enviros” and ski towns had prevented them from developing water to which the city had an undisputed right. They had believed the Environmental Protection Agency’s 1990 decision to scuttle Denver’s proposed Two Forks Dam near Deckers on the South Platte River was an outlier, not a sign of things to come…

Slow to recognize that mountain communities now had the power to kill their water development plans, Utilities officials looked at another alternative. Instead of taking water directly from the wilderness area, the city proposed to build a dam on the mainstem of the Arkansas at Elephant Rock, a few miles upstream of Buena Vista.

A grassroots rebellion against the project was soon evident, as hand-lettered signs appeared along U.S. Highway 24, which parallels the Arkansas. The signs carried a simple message: “Don’t Let Colorado Springs Dam this River!”

It soon became clear that Chaffee County commissioners would not issue a construction permit for any such project, dooming it before the first planning documents were created…

If trans-mountain diversions or dams on the Arkansas were no longer feasible, that left a single alternative for developing the city’s water rights. CSU would have to let its water flow down to Pueblo Reservoir, construct a diversion structure on the dam, and pump it uphill to Colorado Springs.

It would be, water managers believed, the easiest project to build and permit.

“It was just a pipeline,” said CSU water resources manager Gary Bostrom, who has worked 35 years for Utilities. “What could go wrong?”[...]

“We didn’t really understand the importance of partnering with and involving the public in decision-making,” said [Gary Bostrom], “until the Southern Water Project.”[...]

The plan for the Southern Delivery System was presented to City Council in 1992. Among the material submitted to councilmembers was a comprehensive description of the city’s existing water system. Water managers made sure Council was aware of the importance of the task before them.

“The massive scope of this project,” CSU staff noted, “requires a very long lead time to allow for complexities of numerous permitting processes, land acquisition, litigation, design, financing and construction.”

Of all the variables, CSU managers and elected officials gave the least weight to those that may have been the most significant…

“We weren’t worried about hydrology,” said Bostrom. “The years between 1980 and 2000 were some of the wettest years on record. The water was there for the taking. Shortages on the Colorado weren’t part of the discussion.

“We knew about the Colorado River Water Compact of 1922 (which allocated Colorado River water between Mexico and the upper and lower basin states), but it wasn’t something we worried about.”

Then as now, 70 percent of the city’s water supply came from the Colorado River. SDS would tap the city’s rights on the Arkansas, diversifying the portfolio.

“We have to plan for growth,” said Bostrom. “That’s what history tells us. We know that it will be expensive, but the cost of not building a system well in advance of need would be much greater. People complained about the cost of the Blue River (trans-mountain diversion) project in the 1950s, but we wouldn’t have a city without it — we wouldn’t have the Air Force Academy.”

But even as the project moved slowly forward, the comfortable assumptions of a wet, prosperous future began to unravel.

“Exactly 15 years ago today (April 29, 1999),” said Bostrom, “we were in the middle of a flood — remember? We didn’t know it, but that was the day the drought began.”

“…we have a lot of communities on a diminishing aquifer” — Eric Hecox

May 11, 2014

rueter-hessplans

From The Denver Post (Steve Raabe):

The shimmering surface of Rueter-Hess reservoir seems out of place in arid Douglas County, where almost all of the water resources are in aquifers a quarter-mile under ground.

Yet the $195 million body of water, southwest of Parker, is poised to play a crucial role in providing water to one of the fastest-growing metropolitan areas in the U.S.

As recently as a few years ago, developers were content to tap the seemingly abundant Denver Basin aquifer to serve the thousands of new homes built each year along the southern edge of metro Denver.

But a problem arose. As homebuilding in Douglas County exploded, the groundwater that once seemed abundant turned out to be finite. Land developers and utilities found that the more wells they drilled into the aquifer, the more grudgingly it surrendered water.

“Now we have a lot of communities on a diminishing aquifer,” said Eric Hecox, executive director of the South Metro Water Supply Authority, a consortium of 14 water suppliers that serve 300,000 residents.

As water pressure in the Denver Basin steadily declines, developers and water utilities that rely on the aquifer are being forced to drill more wells and pump harder from existing wells.

Enter Rueter-Hess. The massive storage facility — 50 percent larger in surface area than Cherry Creek reservoir — aims to help developers wean themselves from groundwater by shifting to other sources.

The reservoir anchors a multifaceted water plan for the south metro area that includes the purchase of costly but replenishable surface water, reuse of wastewater and a greater emphasis on conservation.

Douglas County, long a magnet for builders enticed by easy access to Denver Basin aquifers, is taking the water issue seriously.

A new proposal floated by the county government would give developers density bonuses — up to 20 percent more buildout — for communities that reduce typical water consumption and commit to using renewable sources for at least half of their water.

“In the past, the county had not taken an active role in water supplies because groundwater was sufficient,” said Douglas County Commissioner Jill Repella. “But we understand that we cannot continue to be solely reliant on our aquifers. What we’re doing today will help us plan for the next 25 years.”

Parker Water and Sanitation District launched construction of Rueter-Hess in 2006 and began gradually filling the reservoir in 2011, fed by excess surface and alluvial well flows in Cherry Creek.

Partners in the project include Castle Rock, Stonegate and the Castle Pines North metropolitan district. Parker Water and Sanitation district manager Ron Redd said he expects more water utilities to sign on for storage as they begin acquiring rights to surface water.

The chief source of new supplies will be the Water Infrastructure and Supply Efficiency partnership, or WISE, in which Denver Water and Aurora Water will sell an average of 7,250 acre-feet a year to 10 south-metro water suppliers beginning in 2016. Most of them are expected to purchase storage for the new water in Rueter-Hess. An acre-foot is generally believed to be enough to serve the needs of two families of four for a year

Parker Water and Sanitation also is exploring ways to develop recreational uses at the dam — including hiking, camping, fishing and nonmotorized boating — through an intergovernmental agreement with other Douglas County entities.

Even three years after opening, the reservoir’s stored water has reached just 13 percent of its 75,000-acre-foot capacity. Yet Rueter-Hess is the most visible icon in Douglas County’s search for water solutions.

At stake is the ability to provide water for a county that in the 1990s and early 2000s perennially ranked among the fastest-growing in the nation. The number of homes in Douglas County has soared from 7,789 in 1980 to more than 110,000 today, an astounding increase of more than 1,300 percent.

The building boom slowed after the 18-month recession that ended in June 2009. Growth rates that had reached as high as 10 percent to 15 percent a year during the 1990s ratcheted down to about 1 percent to 2 percent.

But as the economy has begun recovering, Douglas County is once again “seeing high levels of demand” for new residential development, said assistant director of planning services Steve Koster.

One of the biggest Douglas County projects in decades is Sterling Ranch, a proposed community of 12,000 homes south of Chatfield State Park.

The 3,400-acre ranch sits on the outer fringes of the Denver Basin aquifer, making it a poor candidate for reliance on the basin’s groundwater.

As a result, the project developer will employ a mixed-bag of water resources, including an aggressive conservation and efficiency plan; surface-water purchases from the WISE program; well water from rights owned by Denver billionaire Philip Anschutz; and a precedent-setting rainwater-collection program.

Sterling Ranch managing director Harold Smethills described the Rueter-Hess concept as “brilliant,” even though his development has not yet purchased any of the reservoir’s capacity.

“You just can’t have enough storage,” he said.
