Hillcrest Storage Tank Replacement

Construction Update: May 11, 2017

Work activities onsite continue to be very similar to what has been happening over the last few weeks.

Stockpile Vegetation

Following the soil amendment and seeding, we have begun to see vegetation sprout on the stockpile. A watering plan has been established to continue promotion of germination. 

Vault Work on Access Road Behind S. Hillcrest Drive

The additional work required to finish this area of construction is almost complete. There will be crews on site Saturday (5/13) during work hours. They will be working down in the pipe area and will possibly have an excavator running during that time.

Tank Wall Construction

Concrete placement continues for the walls of tank #1 (on the S. Hillcrest Dr. side of the property) and tank #3 (next to the Canyon Club Condominiums). Tank #1 wall placements will be completed mid-May and Tank #3 wall placements will be completed the end of June.  

Concrete Placement – Roof of Tank #1 and Tank #3

The wall placement for both tanks #1 and #3 is running according to schedule. We anticipate that the next weekend concrete placement, for the roof of tank #1 will occur this summer (the late July – early August timeframe) followed closely by the placement of the roof of tank #3. We are too far out to predict exact dates at this point but will keep you posted as we move closer. These placements will be very similar to what neighbors experienced during the floor placements in December 2016 and February 2017.

Construction hours. General work hours (outside of the weekend concrete placement days) are 7:00 a.m. – 6:00 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 hours will be consistent with weekday hours 7:00 a.m. – 6:00 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.

    The Hillcrest site's three new 15 million gallon storage tanks will be buried up to roof height (rendering, looking west).

  • 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.
