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: Oct. 19, 2017

    Work activities at Hillcrest site

    Concrete Placement

    Roof of Tank 3

    The roof of Tank 3 is now set to be placed two weeks ahead of schedule. The placement will take place on Saturday, Oct. 28. There is a slight chance that the schedule may change due to weather or other project timelines. We will keep you informed if the schedule does change.

    Floor of Tank 2

    Preparation for the floor of Tank 2 will continue through the next couple months. The concrete placement is scheduled for Saturday, Dec. 9 — a year, almost to the day, following the first large concrete placement of the floor of Tank 1. Like the other placements, there is a chance the schedule may change due to weather or other project timelines. We will keep you informed as we get closer.

    These placements will be similar to what neighbors experienced during the Tank 1 and 3 floor placements, and the roof of Tank 1 placement.

    Large stockpile

    Beginning Monday, October 23, there will be up to three scrapers working on the large stockpile. They will be working on and off the stockpile for a week distributing dirt to backfill the Hydro Conduit, which is located between the new and existing tanks (center of the site).

    Weekend work

    Small teams will be working on-site Saturday, Oct. 28, and Sunday, Oct. 29, from 7 a.m. to 6 p.m.

    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.
