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: August 14, 2020

Work activities at Hillcrest site

Tank backfill & stockpiles 
Backfill around the tanks is now complete and the remaining stockpiles are expected to be gone by the end of August. There will be two days at the end of August during which the remaining scraper on-site will be used to flatten the area where the stockpiles were located. 

Cobblestone work will begin around the tanks at the end of the month, which we anticipate will significantly reduce the amount of dust in the area. 

New facility roads
Work on the new access road for the site from Happy Canyon Road has begun. It is expected to be completed and open for use by the end of September. Curbs and gutters on-site will be placed in the next two weeks with paving to follow in early September. Once this road is usable, most truck traffic will be rerouted to this access point and away from the eastern side of the site. The amount of dust will continue to decrease as flatwork for the new roads and concrete placement is completed throughout the site through the end of September.

The irrigation system has been installed along Happy Canyon Road outside of the fence. The remaining irrigation work for the site is expected to begin the week of Aug. 24 with completion expected by the end of September. Planting and seeding is still on schedule to begin in September.  

The permanent fencing along Happy Canyon Road is expected to be completed by the end of August. As the permanent fencing is installed, the blue mesh fencing will be reinstalled to continue to mitigate the amount of dust from the site. 

Dust mitigation
We anticipate the majority of the heavy dust will be reduced as backfill activities are completed. Remaining amounts of dust will continue to drop as we finish removing the stockpiles and laying concrete and flatwork at the site. We will continue to have multiple water trucks on-site spraying as needed to mitigate dust issues in the area. 

Water main replacement project on Happy Canyon Road
The water main replacement project on Happy Canyon Road is progressing on schedule. The contractor is continuing to install the water main from South Hibiscus Way toward South Forest Way. We appreciate your continued patience as this important infrastructure project is completed. The construction schedule currently shows the Happy Canyon Road work will be completed in mid-September. For questions regarding this project, please contact Denver Water’s Customer Care at 303-893-2444.

Road sweeping
We are sweeping the street on Happy Canyon Road three times a week and will continue to sweep on additional days as needed. 

Construction hours at Hillcrest site

We continue to work on Saturdays through the spring, with personnel arriving at 7 a.m. and equipment use beginning at 8 a.m. We do not anticipate working any Sundays for the foreseeable future. 

Weekday working hours remain 7 a.m. to 6 p.m., Monday through Friday.
