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: Aug. 14, 2018

Work activities at Hillcrest site

New MWHC Constructors Contact

MWH Constructors recently made a change in their communications department and we are happy to introduce you to Ms. Casey Corrigan. Casey worked very closely with Katy Perrino in the last year at MWHC and is familiar with the workings and onsite conditions at Hillcrest. Casey will be available to handle any onsite issues or questions you may have.

Water Storage Tanks

The roof of Tank 2 is scheduled to be placed in the early morning of Aug. 25, which will bring construction of the three new water storage tanks to a close. As with past placements, it will occur on a Saturday due to the amount of concrete required.

In late July, the project team began work on the removal of the large stockpile along Happy Canyon Road which will be used as backfill around the tanks. There will be a dust mitigation plan in place and we expect a significant amount of the stockpile to be reduced by late October/November.

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.

Pipe Work

Installation of new pipe will occur along the S. Hillcrest Drive fence line in 2019. We will provide additional information as we get closer to those dates.

Existing Tank Demolition

Demolition of the existing tanks will begin in November. We will recycle the concrete by breaking it down onsite and will use the recycled material to augment the back fill that will surround the tanks and fill in the landscape. The project team will have a dust and noise mitigation plan in place.

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.

We continue to make every effort to keep you updated on schedule and activity changes via Nextdoor and our email distribution list. If you would like to be added to the email update list, please email Julie Seagren or Casey Corrigan.

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.
