Hillcrest Storage Tank Replacement

Construction Update: Feb. 22, 2017

Concrete Placement Completed

The concrete placement went forward as planned on Saturday, Feb. 18.

Road Repair on Happy Canyon Road

The asphalt repair began on Happy Canyon Road the morning of Wednesday, Feb. 22, with completion expected by the end of the day.

Tank Wall Construction Beginning

Wall forms are being constructed to serve as the framework for the concrete walls.

As a reminder, wall forms are currently being constructed at the site. This is the framework in which wet concrete is placed so it takes the shape of the form. Once the concrete hardens, the forms are removed and the gray concrete walls of the tank are exposed. As the concrete is placed, we will rotate the forms clockwise to set up for the next wall placement. While the forms are being constructed now, the first concrete placement for the wall of tank #1 is still a few weeks out. Placement for the tank walls will not be exclusive to Saturday like the placement of the floor and the roof. Wall placement can be done throughout the week as it requires far fewer trucks and cubic yards of concrete. We will make every effort to keep neighbors updated on the schedule. Once we move into full production, we are hoping to place a concrete wall section once every four days. There are 18 wall sections per tank. The walls are 30 feet from the floor of the tank and about 10 feet tall if you are looking at them from the sidewalk.

Construction hours. Work hours are 7 a.m. – 6 p.m. Monday – Friday. Saturday work will continue to be an option that our contractor, MWHC, will retain and use when necessary to keep the project on schedule or at times when the additional work could result in condensing the overall construction timeline. Saturday work is particularly likely through spring as some of the pipe connection work needs to be done while our treatment plants are operating at a lower capacity. Saturday work hours will be consistent with weekday hours 7 a.m. – 6 p.m.

Building Hillcrest Reservoir section of northwest wall in Basin No. 2, 1959Denver Water developed the Hillcrest water storage facility in the early 1960s to replace several small, temporary pumping stations and therefore improve the ability to reliably serve the burgeoning population of southeast Denver.

Crews finished building Hillcrest’s two 15-million-gallon concrete water storage basins in 1960 and completed the pumping station four years later. 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.

To maintain safety at the Hillcrest facility and improve its reliability for water service and hydropower production, Denver Water plans to make major upgrades through work estimated to run from mid-2016 to early 2020 in phases.

  • Phase 1: Tank replacement

    Crews will replace 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. We anticipate the first phase of construction will run from mid-2016 through late 2019.

  • Phase 2: Pumping station replacement

    Crews will replace the pumping equipment, which is outdated, and the pumping station's building. This second phase of construction will overlap with the first and is anticipated for 2018 through early 2020.

    Hillcrest's pumping station, the building above the far left tank in this rendering (looking northeast), will get major upgrades.

  • After construction: Site improvements

    Once completed, the final site will also benefit from significant landscape and irrigation improvements, such as those proposed for the view looking north below.

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.
