Hillcrest Storage Tank Replacement

Construction Update: Jan. 11, 2017

Southmoor Park Neighborhood Association Meeting. We will be providing an update on the project at the Southmoor Park Neighborhood Association meeting on Wednesday, Jan. 18 at 6 p.m. at Thomas Jefferson High School.

Saturday work is expected this weekend (Jan. 14). This weekend crews will continue to work on some of the pipe connection work at the site. In addition, there will be a tree removal company on-site to remove the cluster of trees just to the east of the gate closest to S. Hillcrest Drive. The evergreen tree that had the lights on it this year will remain; however, the trees just to the east of it will be removed. These trees have always been scheduled for removal as part of the project and will be replaced through the new landscape plan at the end of the project. The trees are being removed to make room for a construction trailer that will remain in place until the three tanks are complete.

Construction work. Crews will continue with electrical and piping work over the next week. We anticipate this being low impact given the nature of the work. No significant truck traffic is expected. Additionally, we will have a subcontractor on-site next week (approximately Jan. 16 – 22) to repair the driveway and sidewalk at the main entrance to the facility (the entrance toward the middle of the property). The sidewalk and driveway will be taped off during this time period to allow the new concrete to set. Construction crews and Denver Water staff will use the gate to the east of the property in the interim.

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.

Second concrete placement. The next concrete placement (for the floor of tank 3, closest to the Canyon Club Condominium complex) is still scheduled for Saturday, Jan. 28, 2017. This date is still tentative as weather will play a larger factor this month than for the previous placement. We will keep you posted as we move closer and are able to get more accurate weather reports for that day.

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.
