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: June 17, 2019

Construction Progress/Stockpile Update

During the demolition of existing concrete storage tanks, asbestos was discovered in a small area of concrete supporting the foundation for one of the tanks. As a safety precaution, tank demolition, stockpile removal and backfill work were halted. The issue was immediately reported to the Colorado Department of Public Health and Environment. Denver Water and its contractor, MWH Constructors, isolated and covered the area of concern in accordance with state containment standards.

Denver Water and MWHC have conducted asbestos sampling and are working with CDPHE on the final sampling analysis.

Once analysis is complete, results will be shared in an upcoming newsletter. Construction activities including tank demolition and stockpile backfill work will also resume in early November.


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.

We continue to make every effort to keep you updated on schedule and activity changes via Nextdoor and our email distribution list. If you would like to be added to the email update list, please email Gianna Lombardi or Mechelle Little.

Anticipated timeline

Pumping station replacement phase, 2018 through early 2020: Crews will replace the pumping equipment, which is outdated, and the pumping station's building.
