Here’s the release from the South Metro Water Supply Authority, Denver Water, and the East Cherry Creek Valley Water and Sanitation District (Russ Rizzo/Stacy Chesney/Andy Cohen):

WISE One Step Closer to Delivering Water

  • Purchase of East Cherry Creek Valley Water and Sanitation District pipeline by South Metro Water Supply Authority and Denver Water finalized
  • Water delivery to begin in 2016 following additional infrastructure build-out
  • Partnership represents new era in regional cooperation and water efficiency
  • The southern suburbs of Denver took a significant step forward in shifting to a water system that makes use of renewable water supply on Oct. 21 when members of the South Metro Water Supply Authority and Denver Water purchased the East Cherry Creek Valley Water and Sanitation District’s Western Waterline. The pipeline purchase is a significant milestone in WISE (Water Infrastructure and Supply Efficiency), a partnership between 10 of the South Metro members, Denver Water and Aurora Water to share water supply and infrastructure.

    Using Aurora’s Prairie Waters system, Aurora Water and Denver Water will provide water through the Western pipeline to participating South Metro members on a permanent basis. WISE will also provide a new emergency supply for Denver Water, and offset costs and stabilize water rates for Aurora.

    “The purchase of ECCV’s pipeline makes WISE and the sharing of water supplies possible,” said Eric Hecox, executive director of the South Metro Water Supply Authority. “This is a significant milestone for the WISE Partnership and moves communities throughout the South Metro area one step closer to a secure and sustainable water future,” he said.

    The 20-mile east-west pipeline along E-470 and C-470 has capacity to deliver 38 million gallons of water a day to Douglas and Arapahoe counties.

    “Our sale of this pipeline is mutually beneficial for all the parties involved,” said O. Karl Kasch, president of the ECCV board. “Under the purchase and sale agreement, ECCV will still have the capacity we need in the pipeline, while also supporting a regional solution to one of the most important water challenges facing the Denver metro region. We have always viewed the Western Waterline as an infrastructure asset from which the entire South Metro community can benefit, and that’s what will be accomplished.”

    Under the agreement, Denver Water and Aurora Water will sell an average of 7,250 acre-feet of water a year to South-Metro water suppliers beginning in 2016 with the option to increase to 10,000 acre-feet in future years.

    “We’re thrilled to be moving forward with the WISE Partnership,” said Dave Little, director of planning for Denver Water. “This agreement will create more system flexibility and increase the reliability of our water supply system, leading to a more secure water future for communities throughout the region.”

    WISE water is expected to begin flowing through the ECCV pipeline in 2016, once the remaining infrastructure, such as system interconnects, are complete.

    More coverage from Bruce Finley writing for The Denver Post:

    Denver and south metro suburbs have taken a $34 million step toward water-sharing to wean the suburbs off dwindling underground aquifers.

    The South Metro Water Supply Authority and Denver Water announced Wednesday they bought a 20-mile pipeline — built for $44 million in 2004 by the East Cherry Creek Valley Water and Sanitation District — to carry excess Denver and Aurora water to 10 suburbs including Castle Rock, Centennial and Parker.

    This east-west pipeline is seen as the spine of a new distribution system to move an average of 7,250 acre-feet of water a year to suburbs that, in some cases, remain totally dependent on the finite Denver Basin aquifer.

    “This allows them to change the way they are using the aquifer,” said Eric Hecox, director of the South Metro Water Supply Authority, which represents the suburbs. “It won’t get them off the aquifer completely. It will allow them to use it as a backup supply.”

    Denver Basin aquifer system

    Denver Basin aquifer system

    Colorado has let developers tap aquifers to serve multiplying new homes, but pumping the underground water is becoming more difficult and costly with water tables falling in some areas by 1 to 3 feet a year.

    About two dozen utilities between Denver and Colorado Springs together pump more than 30,000 acre-feet of water a year from about 440 municipal wells, according to water suppliers.

    This Water Infrastructure and Supply Efficiency project, if it works as envisioned, would take advantage of water already used by Denver and Aurora, cleaning it fully in Aurora’s state-of-the-art water treatment plant.

    More pipeline connections must be built, but buying the ECCV pipeline is a major step, Hecox said.

    South Metro paid 85 percent of the $34 million. Denver Water paid $4.7 million.

    The pipeline runs under the 470 beltway and can carry up to 38 million gallons a day. ECCV can keep moving up to 8 million gallons a day to its southeast metro customers.

    “Without that pipeline, we cannot deliver the water,” Aurora Water spokesman Greg Baker said. “Now we can start moving forward toward delivering water.”

    From the Denver Business Journal (Cathy Proctor):

    Denver Water and the South Metro Water Supply Authority, which represents more than a dozen water utilities in the southern edges of the metro area, on Oct. 21 agreed to pay $34 million to buy the pipeline from the East Cherry Creek Valley district. The South Metro water districts is an 85 percent owner of the pipeline and Denver Water paid $4,725,000 for its 15 percent ownership, Bennett said.

    “We found a way between Denver, the South Metro districts and East Cherry Creek to share the capacity of the pipeline, so it will now be used to deliver water to the south metro entities,” said Dave Bennett, a water resource project manager with Denver Water.

    Denver Water, which serves more than 1 million customers in Denver and some surrounding suburbs, also will be able to use the pipeline to capture water and reuse it in its systems, Bennett said.

    “Instead of going out and building a new, duplicate pipeline, we found a way to share that existing infrastructure,” Bennett said.

    The pipeline is crucial to the Water Infrastructure and Supply Efficiency (WISE) partnership, which includes 10 southern water districts, Denver Water and Aurora Water. Under the WISE agreements, treated water that’s been used once by Denver and Aurora and added to the South Platte River will be recaptured at a spot along the river north of Denver. Then, via Aurora’s 34-mile Prairie Water pipeline, the water will be shipped back to the Peter D. Binney Water Purification Facility near the Aurora Reservoir. After it’s treated at the plant, the Western Waterline pipeline will be crucial for moving the treated water to the southern suburbs.

    “The purchase of ECCV’s pipeline makes WISE and the sharing of water supplies possible,” said Eric Hecox, executive director of the South Metro Water Supply Authority. “This is a significant milestone for the WISE Partnership and moves communities throughout the South Metro area one step closer to a secure and sustainable water future.”

    Under the WISE agreement, Denver Water and Aurora Water will sell an average of 7,250 acre-feet of water a year to south-metro water suppliers beginning in 2016 with the option to increase to 10,000 acre-feet in future years. One acre-foot of water equals 325,851 gallons, enough to support 2½ families of four for a year.

    Karl Kasch, president of the East Cherry Creek Valley board of directors, said the sale of the district’s pipeline was beneficial for all parties. The district retained ownership of 8 million gallons per day worth of capacity on the pipeline, which can carry 38 million gallons of water per day.

    “Under the purchase and sale agreement, ECCV [the district] will still have the capacity we need in the pipeline, while also supporting a regional solution to one of the most important water challenges facing the Denver metro region,” Kasch said.

    “We have always viewed the Western Waterline as an infrastructure asset from which the entire South Metro community can benefit, and that’s what will be accomplished,” he said.

    More work needs to be done to connect the pipeline to Aurora’s water treatment plant, connect it to Denver Water’s system, and connect the southern water districts to the pipeline, but that’s expected to be done in the next few years, Bennett said.

    “As groundwater contamination problems go, the stuff leaking from septic systems isn’t terribly sexy” — John Fleck

    October 29, 2014
    Septic system

    Septic system

    From the Albuequerque Journal (John Fleck):

    That, says University of New Mexico engineering professor Bruce Thomson, is precisely the problem.

    “It’s groundwater contamination that’s happening all around us, and we’re not paying any attention,” said Thomson, an expert in treating human waste who delights in describing his academic specialty as “turd mechanics.”

    Septic systems drain away household waste into settling tanks, with the water spilling out into drain fields and the natural filtration of the soil doing the cleanup work. But when they don’t work – because homes are packed too closely together, or the systems are old or poorly maintained, contamination can result. The key problem is nitrates, which can render water dangerous to infants…

    The Carnuel neighborhood, located in Tijeras Canyon, is a good example of the problem that septic systems can cause. Homes in the area depend on wells for their water and use septic tanks to dispose of their waste. Measurements of water quality taken in the area show the problem, Thomson said. The higher up the hill you are, the lower the levels of nitrates. But for residents downstream from the clusters of septic systems, the contamination from uphill neighbors has left well water of questionable quality.

    It’s a classic example of what economists would call an “externality” – when the actions of one person impose costs on someone else.

    “You have an area where the groundwater is essentially undrinkable because of contamination from septic systems,” Hart Stebbins said of Carnuel. When that happens, taxpayers are often on the hook for coming in and helping fix the problem by providing piped-in clean water. That is what is happening in Carnuel, where the Albuquerque Bernalillo County Water Utility Authority is now building a water distribution system extension to serve the community.

    Subdistrict remedies stream depletions — the Valley Courier

    October 21, 2014
    San Luis Valley Groundwater

    San Luis Valley Groundwater

    From the Valley Courier (Rob Phillips):

    This is the 15th article in the series from the Rio Grande Basin Roundtable, regarding the formation and implementation of the Basin Water Plan. The primary goal of Subdistrict No. 1 is to remedy injurious depletions to senior surface water rights and keep those water users whole.

    The Subdistrict has several methods to do this. First, the subdistrict has purchased and leased water, both native to the Rio Grande Basin and water imported from the West slope. This water is stored and released as directed by the Division Engineer to replace stream depletion replacement within stream reaches of the Rio Grande as they occur. By doing this, the river itself is kept whole with wet water replacing the depletions in time, location and amount.

    The subdistrict can also use what are known as forbearance agreements. Colorado law allows the subdistrict to remedy injurious depletions by a means other than supplying wet water. The subdistrict can do this by agreeing with a ditch that, rather than replace depletions with water, the subdistrict will pay the ditch some amount of money for each acre-foot of water the ditch does not receive because of depletions caused by subdistrict wells.

    Each day the Division Engineer tells the subdistrict which ditch is “on the bubble,” that is the most junior ditch that is in priority that day and that is not receiving its full water supply under that priority. The subdistrict then looks at the Annual Replacement Plan to see the depletions caused by subdistrict wells on that day, water that the ditch on the bubble would have received. The subdistrict keeps track of the total amount of water due to each ditch that has a forbearance agreement and pays them at the end of the year. The ditch can then do what it wants with the money, for example upgrading the ditch or simply dividing it up among the ditch users. Forbearance agreements allow ditches and water users to remain whole, while not locking up scarce water resources. So far, the subdistrict and the forbearing ditches are very happy with this arrangement and look forward to continuing working together to reach the best solution for everyone. How the subdistrict is working towards aquifer sustainability

    Throughout the recent drought, the aquifer has been shrinking as producers pump more water than is recharged back to the aquifer. The other primary goal of Subdistrict No. 1 is to recover and sustain the Unconfined Aquifer below the subdistrict to the level that existed in the early 1980s. The primary way the subdistrict plans to do this is by reducing the amount of irrigated acres within the subdistrict, which will reduce the amount of pumping from the aquifer. This concept is built into the Subdistrict’s Plan and requires 20,000 acres be retired by the fifth year from judicial approval of the plan, 30,000 acres less by the end of the seventh year, and up to 40,000 acres less by the end of the tenth year all from a base year of 2000.

    One tool the subdistrict has to meet these goals is financial incentives and participation in the federal Conservation Reserve Enhancement Program (CREP) to retire up to 40,000 irrigated acres. Currently, 1,970 acres were enrolled in the program in 2013 while another 1,370 acres are currently proposed in 2014. However it is not just CREP acres that count towards the 40,000-acre goal, any program or change that retires acres reduces pumping and assists in achieving and maintaining sustainability . But remember, the subdistrict can only provide incentives, it does not have the power to require wells stop pumping.

    Conclusion

    The producers of the closed basin area within the San Luis Valley stepped forward when no one else did and created a subdistrict and imposed fees on themselves to replace their wells’ depletions and work to recover and sustain the unconfined aquifer. They did this not because rules or regulations were in place requiring this action, but because they believed these things had to be done.

    The process has never been easy and the debate about the best way to achieve the subdistrict’s goals continues. But the subdistrict, led by its board of managers, has continuously worked towards those goals and they remain the leaders in the Valley for replacing depletions and working towards sustainability . Currently, other proposed subdistricts within different hydrological areas of the San Luis Valley are going through the same processes in an attempt to have their plan up and running before the state engineer’s ground water rules are approved within the Rio Grande Basin.

    These forming subdistricts have watched and learned from Subdistrict No. 1’s struggles and accomplishments . Those other subdistricts will provide the same protection to their wells, a locally based and operated group that provides an alternative to state administration of ground water withdrawals in Division 3 while protecting senior surface water rights and providing for a long-term , sustainable ground water system.

    The Plan of Water Management, Annual Replacement Plans and other information on the subdistrict and the aquifers are available on the Rio Grande Water Conservation District’s website: http:// http://www.rgwcd.org/page9.html

    Meanwhile Sub-district No. 2 is gearing up for operations according to this report from Lauren Krizansky writing for the Valley Courier:

    Well owners residing in the Valley’s second sub-district are ready to push forward with a petition after months of voluntary work.

    Rio Grande Water Conservation District (RGWCD) Program Manager Cleave Simpson updated the Alamosa County Commissioners (ACC) Wednesday morning on the latest happenings regarding the creation of the next sub-district , which sits in both Alamosa and Rio Grande Counties.

    Sub-district No. 2, also known as the Rio Grande Alluvial Sub-district , is comprised entirely of unconfined wells, and is taking on a different form than Sub-District No. 1, he said. The zone is much smaller, only 300 wells compared to 1,000, participation is voluntary and there is no “sustainability requirement” because the wells do not tap into the confined aquifer.

    “We are not drawing a boundary,” Simpson said. “We will go to each individual landowner… There are not the same benchmarks to meet.”

    Out of the second sub-district’s 300 wells, 152 average more than 10 acre-feet a year, making them subject to the state’s demand to either join a sub-district or to develop an augmentation plan. There are 10 non-private wells in the mix and 60 private well owners.

    “It will be a patchwork of parcels,” Simpson said.

    Out of those well owners, he said between 12 and 15 have regularly participated in the workgroups over the past few months, and they represent more or less half the wells in the second subdistrict .

    In addition, the City of Monte Vista, the Town of Del Norte, Homelake, Colorado Parks and Wildlife and two school districts are in the zone, but will not join the second sub-district because government entities cannot legally be assessed.

    They will be held, however, to the same standards, he said, and have the option to contract with Sub-district No. 2, which would include them in its Annual Replacement Plan.

    Although assessment methods and fees to replace depletions are still to be determined, he said Subdistrict No. 2 is ready to petition for legitimacy.

    “They are ready to go to the public,” Simpson said. “They are ready to start these discussions.”

    It depends on where the state is with its pending water rules and regulations in coming months, he said, but the second sub-district hopes to submit its petition to the district court in January 2015.

    “The (water) model and rules and regulations are not final ,” Simpson said. “That could cause a delay.”

    Once Sub-district No. 2 is established, he said a board of managers (BOM) will be appointed via a court-approved process.

    If there is no opposition to the to the second subdistrict’s formation, he said the BOM’s first task will be to draft a management plan, and, if it is also goes unchallenged , fees assessments will begin in late 2015 with collection notices delivered to Sub-district No. 2 participants in conjunction with their January 2016 county issued tax documents.

    Due to its uniqueness, he said the second sub-district has options when it comes to mitigating its groundwater depletions.

    “There could be some reduction in irrigated agriculture,” Simpson said, “but we might see changes in technologies, crops requiring less consumption and increases in (water) efficiency.”

    He added the value of the zone’s water could also increase, but that is also to be determined.

    Sub-district No. 1 has resulted in increased values, in some cases almost double, and is drawing interest from buyers from outside of the Valley. The Rio Grande Alluvial Sub-district is the second out of six identified in the Valley to come to fruition under the watch of the RGWCD. Alamosa County will eventually have three within its borders. In addition to Subdistricts No. 1 and No. 2, the fourth sub-district will also fall within its jurisdiction, but it is still in an infant stage.

    “It’s good to see the well owners come together,” said Alamosa County Chair Michael Yohn. “Everyone has to be accountable for their water use.”

    Lake Pueblo State Park: Proposed new pumping rules to be discussed November 17 #ArkansasRiver

    October 17, 2014

    Arkansas River Basin -- Graphic via the Colorado Geological Survey

    Arkansas River Basin — Graphic via the Colorado Geological Survey


    From The Pueblo Chieftain (Chris Woodka):

    Groundwater rules that could help certain farmers avoid some of the cost of water court applications are being considered for the Arkansas River basin.

    “We’re not necessarily committed to this idea, but it may have benefits,” Water Division 2 Engineer Steve Witte told the Southeastern Colorado Water Conservancy District board Thursday. “The public needs to weigh in.”

    The first chance to do that will be at a meeting at 1 p.m. Nov. 13 at the Lake Pueblo State Park visitors center auditorium.

    The rules would apply to water replacement plans for post-1985 pumping, new uses for wells drilled prior to 1985 or new wells. They would provide an administrative alternative to water court, which can be too expensive for individual water users to navigate.

    Witte reviewed the history of legal issues surrounding wells in the Arkansas Valley, including the 1972 attempt to reconcile surface and groundwater use, the Kansas v. Colorado case filed in 1985 that led to the 1996 well rules and the Simpson v. Bijou decision by the state Supreme Court in 2003 that took many well augmentation plans out of the hands of the state engineer.

    “Decreed plans for augmentation costs have been so prohibitive in the South Platte that thousands of wells remain shut down to this day because of Simpson v. Bijou,” Witte said. There have also been instances in the Arkansas River basin, he said after the meeting.

    On the same day that the Simpson v. Bijou ruling came, the state Legislature entered the Arkansas Valley well rules into law. In 2003, it also gave the state engineer’s office authority to approve five-year substitute water supply plans and to develop future rules.

    Nearly 1,800 wells in the Arkansas Valley are covered by Rule 14 group augmentation plans under the 1996 rules, and those would stay in place even if new well rules are adopted.

    The new rules could benefit a farmer who wants to use his own surface water rights to replace water pumped from wells, revegetation projects or even someone drilling a new well for a business, Witte said. At the same time, they would protect downstream water users and Colorado’s obligation under the Arkansas River Compact.

    Witte acknowledged that there might an “augmentation gap” that makes finding sources of replacement water difficult, as discussed by the Arkansas Basin Roundtable recently. Permanently changing water uses still would require a trip to court.

    But he said the purpose of the rules would be to give farmers a new tool to stay in business while complying with water law.

    “We’re relying on data that were developed 30 years ago,” Witte said. “Life goes on and we need to think of ways to adjust and not be hampered by things already in place.”

    [Central] Water district seeks tax revenue for ag infrastructure — The Greeley Tribune

    October 13, 2014

    Typical water well

    Typical water well


    From The Greeley Tribune (Kayla Young):

    Two Weld County ballot initiatives aim to direct more tax dollars toward the Central Colorado Water Conservancy District with the intention of increasing water infrastructure and maintenance investments for agriculture and communities.

    Ballot issue 4B proposes increasing the district’s annual tax allotment to a maximum of $750,000 in order to provide a stable water supply and maintain storage projects for farms, ranches and municipalities in Weld, Adams and Morgan counties.

    Broken down, the home-owners’ tax would equate to an additional $2.34 a year for the owner of $100,000 house, said Kathy Parker, the district’s public information officer. She specified that business owners would not be subject to the levy.

    Board member Randy Knutson emphasized the need for infrastructure improvements, especially following the wear and tear brought in 2013.

    “With the flood last year and the increased maintenance and repair that we’ve been faced with, that’s a big reason for this particular tax increase, that and aging infrastructure,” he said.

    He encouraged non-agricultural landowners to consider the possible benefits the tax would bring to overall quality of life.

    “They benefit from agriculture; they benefit from water quality; they benefit from delivery of water, which eventually provides food for them,” he said.

    The second ballot issue, 4C, would “de-bruce” funding restrictions created through the Taxpayer Bill of Rights (TABOR). In other words, the issue would open up excess tax revenue and grants not currently available to the district due to tax code regulations.

    “We have lost millions of dollars by not being able to participate in funding and grant money that has been available. The TABOR amendment has limited our ability to participate,” Knutson said.

    Western Governors protest U.S. Forest Service water directive — Las Vegas Review-Journal

    October 12, 2014

    From the Las Vegas Review-Journal (Sean Whaley):

    In a letter signed by Gov. Brian Sandoval, the Western Governors Association is criticizing a proposed U.S. Forest Service directive that seeks significant changes to water policy without their involvement.

    The agency says the proposed directive would create a more consistent approach in its evaluation and monitoring of the impact on groundwater from actions on national forest system land.

    The Western Governors say the agency is over-reaching.

    “This proposed directive was developed without any state consultation of which the Western Governors’ Association (WGA) is aware,” the letter dated Oct. 2 notes. “We invite the USFS to work through WGA, Western States Water Council, and individual states to facilitate dialogue on ways to improve this (and any future) proposed directive.”[...]

    The USFS has said the directive is needed to establish a consistent approach for addressing both surface and groundwater issues that appropriately protects water resources, recognizes existing water use, and responds to the growing societal need for high-quality water supplies.

    But Sections of the directive “assume that the service has some type of authority over the management of groundwater, which it does not,” the governors counter in their letter. “The proposed directive should clearly state that state issued water rights for allocations of water must be recognized. The USFS does not have the authority to limit the amount of withdrawals authorized by a state. Limiting the quantity of groundwater withdrawals through special use authorizations would, in effect, amount to superseding states’ authority to issue water rights.”

    Sandoval and other governors also express concern about the “rebuttable presumption” that surface water and groundwater are hydraulically connected, regardless of whether state law treats these resources separately.

    “The directive should defer to the laws of individual states in recognition of their authority over water management,” the letter says.

    The governors also say the directive requires the federal agency to evaluate water right applications on adjacent land that could adversely affect Forest Service groundwater, which oversteps the agency’s authority.

    The comment period on the proposed directive ended Oct. 3.
