Imported supplies

While securing local water rights and conserving existing water supplies is important, the Town's plan also includes looking at opportunities to partner with others in our region to further secure the community’s water future. The Legacy Water Projects in particular are the WISE and the Box Elder projects. They are also known as the alternate source of supply projects. These projects are designed to import water from Denver, Aurora, and other water rights the Town is purchasing on the South Platte River north of Denver.

Alternate source of water supply

In Oct. 2012, Town Council voted in favor of pursuing a hybrid solution for the Town's long-term water goals. Town staff entered into negotiations with Stillwater Resources and WISE partnership, which could result in renewable water being imported into the Town as soon as 2017. For more information, view a timeline of this process.

South Metro Water Supply Authority

The South Metro Water Supply Authority has been instrumental in developing opportunities for smaller Front Range water providers to partner with larger ones, such as Denver and Aurora. The authority also has been implementing studies and projects as identified in the Regional Water Master Plan.

WISE Partnership

In 2009, Castle Rock Water became part of the WISE Partnership. That partnership of ten South Metro organizations has signed agreements to import renewable water from Denver and Aurora. To date, the Town has invested approximately $5.3 million into a pipe big enough for a man to walk through (the Western Pipeline) that runs approximately 20 miles along E-470. This pipe is a critical piece of the system that will not only allow us to import WISE water but also water from the Box Elder project. 

Additional large pipelines, pumps and tanks will need to be constructed in the next one to two years, from E-470 to Rueter-Hess Reservoir and from Rueter-Hess Reservoir to the Town, in order to ensure that WISE water can arrive in the Town by 2017. These same pipeline investments of an estimated $38.6 million will also be a key part of the Box Elder project carrying that water to the Town in the future. 

WISE local infrastructure

Several South Metro Authority members are currently partnered together on a waterline construction project. This water pipeline will convey from the Western Pipeline at E-470 and Peoria Street / Chambers Road south towards Rueter-Hess Reservoir and Water Treatment Plant. 

Box Elder project

Castle Rock has invested about $16 million into the water rights in the South Platte River, north of Denver in Weld County. That’s about 72 percent of the total water rights targeted for purchase in the Box Elder project. The Town has purchased the Box Elder well field in Weld County that could be used to divert these water rights. The Town has also secured capacity in the Keenesburg Pipeline which is a key piece of infrastructure for transporting the imported water from Box Elder.

Securing the remaining water rights for this project will be a focus in the next several years. Many of the details of the Box Elder project are still in the planning stage, but the goal is to bring water from this project to Town sometime after the year 2025. 

Both of the Legacy Water Projects are important to the community and have become a good fit into Castle Rock Water’s overall long-term water puzzle.

East Cherry Creek Valley Water and Sanitation District Northern Pipeline

An agreement to purchase capacity in the northern pipeline has been negotiated and is available to all South Metro Water Supply Authority members. The Town is planning to purchase additional capacity in this pipeline and is actively negotiating directly with the authority members and East Cherry Creek Valley Water and Sanitation District (ECCV) on the final share of the pipe's capacity and cost. 

WISE infrastructure construction

As Castle Rock Water works to secure the community's long-term water plan, the WISE project continues to make progress. Various pieces of the local infrastructure are either in the design phase or ready to be designed. The total WISE expenditures to date are $7.3 million. Over the next five years, a total spending of $29.3 million is expected. Pipeline project updates are available below. The purpose of this pipeline project is to import water from the existing WISE / Box Elder Pipeline to the Ray Waterman Regional Water Treatment Plant.

The design of the pipeline and Rueter-Hess Water Treatment Facility upgrades is complete and construction began in June 2016. The project is anticipated to be complete by May 2017.

Existing Parker Water and Sanitation District Pipeline
Castle Rock Water partnered with Parker Water and Sanitation District on a study of the hydraulics of the WISE water flow. The study is complete and discussions regarding additional infrastructure design / construction have begun with Parker Water and Sanitation District. 

Canyons North Line (red)
The Canyons North Line was awarded to Western Summit/Stantec team in May 2016. This pipeline will convey WISE water from Parker Water and Sanitation District’s existing infrastructure near Rueter-Hess Reservoir to the Town. The work is scheduled to be complete by Nov. 2017. The cost for this work will be split between Parker Water and Sanitation District, Castle Rock Water, and Dominion is working on a lease-purchase agreement with the Town of Castle Rock to purchase capacity in the pipeline also.  

Pipeline to Ray Waterman Water Treatment Plant
The design of the final leg of the local infrastructure is complete. All property easement agreements and acquisitions for the five-mile corridor are complete. Construction bids were received in Oct. 2016 and Town Council will be considering the construction services contract with the low bidder, Garney Companies, Inc. at an a Nov. 2016 Town Council meeting. Construction will begin after Notice of Award in Nov. 2016 and is anticipated to be complete by July 2017.
Existing WISE / Box Elder Pipeline (pink - top of map)
The Western Pipeline modifications are approximately 50 percent complete. Substantial completion is scheduled for Dec. 2016. There have not been any change orders to date. 

The design of the Quebec Street Water Treatment Plant is 100 percent complete and construction has begun. The necessary tie-ins are complete and underground piping work including disinfection and pressure testing will be complete in Mar. 2016. 

The Smoky Hill Tank as shown in the photo to the right was completed in Aug. 2016.
