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

Construction site neighbors: Denver Water/MWHC are planning door-to-door visits the afternoon of Wednesday, July 5 to touch base and answer questions.

    Work activities at Hillcrest site

    On-site work activities continue to be very similar to what has been happening over the last few weeks.

    Concrete roof placements

    The next concrete placement will be the roof of Tank No. 1 (South Hillcrest Drive side of the property). It has been moved to late summer (late August or early September) and will be followed closely by the placement of the roof of Tank No. 3. We are too far out to predict exact dates at this point but will keep you posted. These will be very similar to what neighbors experienced during the floor placements in December 2016 and February 2017.

    Tank wall construction

    Concrete placement for the walls of Tank No. 1 is completed. Wall placements for Tank No. 3 will be completed next week. Due to high temperatures, crews will begin pouring the final wall at 7 a.m., on Tuesday, June 27. Concrete trucks will be on-site as early as 6 a.m.

    Stockpile vegetation

    Following the soil analysis, seeding and straw placement efforts completed in April, we are starting to see native grass growing on the stockpile. The grass, which will help mitigate dust, is germinating quickly on flat surfaces and more slowly on steep pitches. The team is continuing to monitor how the grass establishes and will water accordingly.

    Construction hours at Hillcrest site

    General work hours (outside of weekend concrete placements) are 7 a.m. to 6 p.m., Monday to 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.
