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

    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.

    Douglas County joins WISE project

    August 31, 2014

    douglascounty

    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.

    Aurora Water embarks on expansion of Prairie Waters

    May 8, 2014

    prairiewaterstreatment

    From The Denver Post (Megan Mitchell):

    Aurora Water has begun construction to expand the city’s Prairie Waters Project for the first time since the natural water filtration and collection system opened in 2010. Projects nixed from the original construction plan kept the $659 million project about $100 million below its initial budget. Now, those projects are being called back up to make sure Prairie Waters stays on track for exponential growth over the next 40 years.

    “The expansion part of the project has been planned from the very beginning,” said Marshall Brown, executive director for Aurora Water. “This year, we’re at a place where we can prioritize the growth and look toward the future of system capacity.”
    Crews have begun digging six new collection wells in between the existing 17 wells that collect water from a basin near the South Platte River in Weld County, downstream from the Denver Metro Wastewater Reclamation District’s plant. From there, the water is piped through wells 44 miles south to treatment and storage facilities in Aurora for residential use.

    Along the way, the water is pulled through 100 feet of gravel and sand. This 30-day, natural process helps pull large contaminants out of the water.

    Two new filter beds will also be installed at the Peter D. Binney Water Purification Facility near the Aurora Reservoir this year. At the Binney facility, water is treated with chemicals and ultraviolet lights to make it potable.

    The cost of the expansion projects is $2.9 million, said Greg Baker, spokesperson for Aurora Water. He said water tap fees will not be affected by the new wells and filters this year.

    “We plan our capital projects (which are predominantly paid for by development or tap fees) well in advance,” Baker said. “We plan for these expenses so that our rates don’t roller coaster based on immediate projects.”

    Right now, Prairie Waters is spread over 250 acres in Weld County and is only built out to about 20 percent of its total potential capacity. Baker said the system currently provides 10 million gallons of water per day. At full build-out, Prairie Waters will able to provide 50 million gallons of water per day.

    The project itself was conceived in response to extreme drought conditions in 2003.

    “Ideally, we would like to have two years’ worth of supply stored in the system at all times,” Brown said. “Aurora’s system varies between one and two years’ worth of storage now.”

    The long-term vision for the project involves well development all the way down the South Platte River to Fort Lupton, as well as adding more physical storage components. Aurora Water has already started to acquire additional property for capacity expansion in the future.

    Baker added: “As Aurora’s population grows, we will expand into the system to support that growth.”

    Highlands Ranch water rates to go up in 2014

    Highlands Ranch

    Highlands Ranch

    From the Highlands Ranch News (Ryan Boldrey):

    Following spikes of 2 percent in 2012 and 3.8 percent in 2013, Highlands Ranch residents are expected to see rates go up 6.8 percent this coming year. This year’s proposed increase is due to the district’s involvement with both the Water Infrastructure and Supply Efficiency Partnership (WISE) and Chatfield Reallocation Project, said Bruce Lesback, CWSD director of finance and administration…

    “We held off as long as we could before increasing rates to this level for our customers, but it appears both projects are now going forward,” Lesback said.

    For CWSD, the two projects are a major step toward cementing a long-term water supply and not relying as much on groundwater or leased water.

    “We’ve got many years of full supply, but some of that full supply comes from leases that are not long-term,” CWSD General Manager John Hendrick told Colorado Community Media earlier this year. “We want to add to our portfolio with long-term or near-permanent surface water sources.

    “We’ve got ample groundwater for droughts, but in wet years we’ll now be able to take in more than we need to and top off our reservoirs with surface water.”[...]

    A public hearing was held Nov. 25 on the proposed CWSD budget. The board of directors will vote to adopt the 2014 budget at its Dec. 16 meeting.

    Reuse: The WISE Partnership gets approval from the Denver Water Board

    August 20, 2013

    prairiewaterstreatment.jpg

    From the Denver Business Journal:

    Denver Water last week approved the WISE partnership agreement that clears the way for the utility to delivery treated water to the area’s southern suburbs.

    Approval of WISE, which stands for Water Infrastructure and Supply Efficiency, formalizes the regional cooperative water project. The agreement calls for the permanent delivery of 72,250 acre-feet of treated water from Denver and Aurora to members of the South Metro Water Supply Authority (SMWSA).

    SMWSA was formed in 2004 from the banding together of smaller water utilities in south Denver.
    With the agreement now in place, some of the water that currently flows down the South Platte River and out of the state would be recaptured by Aurora’s 34-mile Prairie Waters Pipeline and pumped back to the Peter D. Binney Water Purification Facility near the Aurora Reservoir. There, the water would be treated and piped to the southern suburbs.

    The water delivery will begin in 2016. Members of the SMWSA must have infrastructure in place to move the water from the purification facility. The cost of the water and infrastructure for its delivery is estimated at $250 million over the next 10 years. Each member will independently determine how to finance their share of the project.

    The participating members of SMWSA are the town of Castle Rock, Dominion Water & Sanitation District, Stonegate Village Metropolitan District, Cottonwood Water & Sanitation District, Pinery Water and Wastewater District, Centennial Water & Sanitation District, Rangeview Metropolitan District, Parker Water & Sanitation District, Meridian Metropolitan District and Inverness Water & Sanitation District.

    Parker Water and Sanitation District board is evaluating joining with Aurora and Denver in the WISE project

    April 29, 2013

    parkerrhodeislandhotel1908bestofparker.jpg

    From the Parker Chronicle (Chris Michlewicz):

    The Parker Water and Sanitation District board of directors will hear a presentation later this month from new manager Ron Redd, who will recommend that the district enter into WISE, the Water, Infrastructure and Supply Efficiency project. Six members of the South Metro Water Supply Authority, including Pinery Water and Wastewater, the Cottonwood Water and Sanitation District and Stonegate Village Metropolitan District, committed to WISE by signing intergovernmental agreements in late March. The agreements will bring nearly 7,000 acre-feet of recycled water to the south metro area…

    The Parker Water and Sanitation District board asked Redd to examine the possibility of buying 500, 1,000 or 1,500 acre-feet through the WISE project. He was expecting to receive the results of a cost analysis on April 5 to determine the possible financial impacts. Any rate hikes on customers would likely be implemented incrementally and equate to about 2.5 percent to 3 percent per year, Redd said, cautioning that those figures are preliminary. The cost of WISE water increases annually over an eight-year period.

    It would be relatively easy, Redd said, to move the reclaimed WISE water from Aurora to Parker if the district can come to an agreement to use a pipeline along E-470 owned by East Cherry Creek Valley Water and Sanitation District. If the board gives approval, the intergovernmental agreement would be signed by late May…

    Rueter-Hess Reservoir, which contains 5,700 acre-feet of water and was built to store 70,000 acre-feet, will be paid off by the time the Parker Water and Sanitation District takes on more debt to build pipelines to transport the water that will be needed for the future.

    Meanwhile, Centennial has inked an IGA with the WISE Partnership. Here’s a report from Ryan Boldrey writing for the Highlands Ranch Herald. Here’s an excerpt:

    Centennial Water and Sanitation District was one of six members of the South Metro Water Supply Authority to sign an IGA this past week committing to more renewable water by way of the Water Infrastructure and Supply Efficiency Partnership. Through the agreement, Aurora Water and Denver Water will provide roughly 7,000 acre-feet of fully treated water annually to participating SMWSA members and deliver it in phases, starting in 2016. As part of the IGA, the participating South Metro WISE entities have agreed to fund new infrastructure that will move the water from Aurora’s Binney Water Purification Facility to its end locations. “A region-wide water solution makes more sense than having each water entity fending for themselves to source, treat and deliver renewable water to customers,” said Eric Hecox, executive director of SMWSA. “We’re excited about the progress we’re making through WISE towards transitioning the region from nonrenewable groundwater to renewable water.”

    Hecox said that the agreement helps provide SMWSA with about a third of the necessary water that participating entities will need long-term. From here, work will continue on the Chatfield Reallocation Project as well as of other options and alternatives to bring more water to the region…

    For Centennial Water specifically, it’s another step toward cementing a long-term supply and not relying as much on groundwater or leased water. “We’ve got many years of full supply, but some of that full supply comes from leases that are not long-term,” said Centennial Water and Sanitation District General Manager John Hendrick. “We want to add to our portfolio with long-term or near-permanent surface water sources…

    Other SMWSA members committing to the project at this time are Cottonwood Water, Meridian Metropolitan District, Pinery Water, Rangeview Metropolitan District and Stonegate Village Metropolitan District. Hecox said he expects Dominion, Inverness, Castle Rock and Parker water districts to sign the IGA by the end of April. SMWSA members not expected to take part in the IGA include: Castle Pines Metro, Castle Pines North, East Cherry Creek Valley, and Arapahoe.

    New Roxborough Water and Sanitation District water treatment could cost $23 million

    January 21, 2013

    roxboroughstateparkcpw.jpg

    From the Castle Rock News-Press (Rhonda Moore):

    The Roxborough water treatment plant, at more than 50 years old, has lasted beyond the end of its useful life and, according to the district board, it’s not a matter of whether disaster will strike, it’s a matter of when. The district is waiting to hear from its customers who must decide how to pay for a new facility, estimated to cost as much as $23 million.

    The new plant will replace the one purchased in 1972 from Aurora Water, according to the district. The existing plant was built in 1958 and refurbished at the time of the purchase. It has outlasted its expected 30-year lifespan by about 20 years, according to the district board…

    Completion of a new facility will cap a long-term water plan that ensures delivery of water to Roxborough residents for the next 100 years, he said.

    Moore was instrumental in reaching a 2010 deal with Aurora Water to get water to Roxborough residents in what Moore calls the most comprehensive, sustainable water plan in Douglas County. In the deal, Roxborough signed a 99-year lease with Aurora to buy into the Aurora system for $22.3 million, securing water to serve Roxborough’s build-out population of 3,800 units. The deal does not allow Roxborough to sell water outside of its boundaries, which means the Roxborough plant will not be designed to serve residents in surrounding neighborhoods, including the proposed Sterling Ranch development, Moore said…

    The district announced its plans in 2012 and in December sent a questionnaire to customers asking them to select one of three payment options for financing the new plant. Among the options are a $20 monthly hike in water rates, beginning in March or April, which would allow the board to move forward with design and financing in the first quarter of 2013; a $10 fee, which would double to $20 by 2014 and delay the start of construction by about 12 months; or a $5 fee that would increase every six months to a $20 fee by 2014, which would delay start of construction by about 18 months.

    The district has about $5 million in capital reserves to contribute to the plant and is aiming for a 30-year note to pay the balance, Moore said.

    Moore has been fielding residents’ questions, many of which revolve around the district’s policy to limit outdoor watering during the summer to twice a week. The board has yet to vote on watering restrictions, Moore said. The new plant will have a 4 million-gallon-per-day treatment capacity, double that of the existing plant.
