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: Sept. 7, 2017

    Work activities at Hillcrest site

    Concrete Placement

    Saturday Construction (Sept. 9)

    Crews will be onsite Saturday to work on prepping the site for the Tank 1 deck (roof) concrete placement occurring Saturday, Sept. 16. They will be working during the standard hours of 7 a.m. – 6 p.m. There will be trucks accessing the site throughout the day.

    Roof of Tank 1 and Tank 3

    The concrete placement for the deck (roof) of Tank 1 (located closest to South Hillcrest Drive) is still scheduled for Saturday, Sept. 16 and will be followed closely by the placement of the roof of Tank 3, which is tentatively scheduled for November. Since we are still a week out from Tank 1, and a few weeks out from Tank 2, there is a chance that the schedule may change due to weather or other project timelines. We will keep you posted if the schedule changes. Please note that we will have a community outreach event on the day of the Tank 1 roof placement. We will provide coffee and donuts, and answer any questions you may have. We would love for you to stop by!

    Floor of Tank 2

    Preparation for the floor of Tank 2 will occur in the coming weeks. The concrete placement is scheduled for December — a year, almost to the week, following the first large concrete placement of the floor of Tank 1. We are too far out to predict the exact date at this point but will keep you posted as we move closer.

    These placements will be similar to what neighbors experienced during the floor placements in December 2016 and February 2017.

    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.
