Hillcrest Storage Tank Replacement

Durable design, less susceptibility to leaks

To maintain safety at the Hillcrest water storage facility and improve its reliability, Denver Water is making major upgrades through work estimated to run through early 2020.

Why it’s important

Denver Water developed the Hillcrest water storage facility in the early 1960s to replace several small, temporary pumping stations and improve the ability to reliably serve the burgeoning population of southeast Denver. Since then, the area’s population has continued to grow, placing increasing demand on the storage and pumping facilities on top of the wear and tear expected to come with age.

The major upgrades this project brings to the Hillcrest facility are an important part of Denver Water’s plan for continued reliable water service to the southeast Denver area.

How it affects our customers

We have made some great progress on-site over the past couple weeks. Please see the updates below as a reminder for what to expect over the next couple months, including concrete placements this fall. 

Construction update: April 25, 2017

Work activities at Hillcrest site

Pipeline Replacement on West Side Property

We are finishing the pipeline replacement along the South Hillcrest Drive side of the property. The new pipeline has been installed and is being backfilled. We will be removing the remnants of the old pipeline from the site this week.


Activity continues on the stockpile as crews use this soil to backfill around various vault and pipe projects onsite. We expect to continue to use the stockpile for backfill purposes through the end of May. The water truck will be running during this time.

Tank Construction Update

Tank 1 is being disinfected and tested in anticipation of going into service in the next week or so. Tank 3 is officially in service and operating in the distribution system. We are pouring the remaining walls for Tank 2 on April 25, and are still on track for a roof pour in late summer of this year. We will keep you posted on the details for that Saturday work as we get closer.

Existing Tank Demolition

Once the new tanks are in service, demolition of the existing tanks is scheduled to begin. We anticipate this occurring this summer. We will recycle the concrete by breaking it down onsite and will add that recycled material to the backfill that will surround the tanks and fill in the landscape. The project team will have a dust and noise mitigation plan in place. We will have more details for you as the new tanks are completed and brought online.

Pump Station Construction

Design of the new pump station is nearly complete. Construction will begin in late 2018 and run through 2020. Demolition of the existing pump station will not occur until the new pump station is online.

Reminder: Contact Update

Katy Perrino has accepted a position outside of MWHC so she will no longer be our onsite contact. While MWHC works to replace her, please feel free to contact Katie Knoll with any issues or questions and she will work with the onsite project team to resolve those.

Construction hours at Hillcrest site

General work hours (outside of weekend concrete placements) are 7 a.m. to 6 p.m., Monday through Friday. Saturday work (with the same hours) will continue to be an option that our contractor, MWHC, will use when necessary to keep the project on schedule or when the work could condense the overall timeline.

Anticipated timeline

  • Tank replacement phase, mid-2016 through late 2019: Crews are replacing the two 15-million-gallon rectangular storage tanks with three same-sized, circular post-tensioned concrete tanks — a durable design less susceptible to leaks. The new tanks will sit slightly south of the existing tanks and will be buried up to roof height, which will be visible.
  • Pumping station replacement phase, 2018 through early 2020: Crews will replace the pumping equipment, which is outdated, and the pumping station's building.
