News on Tap: Upgraded storage for the water down below

From Denver Water (Jimmy Luthye):

$100 million Hillcrest project concludes a decade of improvements to underground reservoirs and pumping stations.

When it comes to storing water, Denver’s picturesque mountain reservoirs get all the glory.

Less visible, but just as important, are the 30 underground storage tanks in 18 locations around the metro area, each storing anywhere from 2.5 million to 25 million gallons of water, delivered from one of Denver Water’s three drinking water treatment plants.

In 2011, Denver Water embarked on a decade-long transformation project that began with the expansion of the Lone Tree underground storage site. Three projects later, those efforts will culminate in 2020 when we complete a $100-million overhaul of the Hillcrest water storage facility in southeast Denver.

Hillcrest was born in the late 1950s and early 1960s, when Denver Water built a state-of-the-art storage and pumping facility to replace several small, temporary pumping stations.

Much has changed in 50-plus years, and with increased water demands from the ever-booming Denver metro area, particularly southeast of town, it was time for a makeover.

The existing pumping station at Hillcrest was completed June 19, 1964.

Since early-2016, Denver Water has worked to replace Hillcrest’s two existing 15-million-gallon rectangular storage tanks with three 15-million-gallon, circular, “post-tensioned” concrete tanks…

The new tanks will sit slightly south of the existing tanks and will be buried up to their roofs, which will be visible.

In addition to the new tanks, the Hillcrest pumping station — one of 22 in the Denver Water distribution system — is getting its own upgrade.

Beyond Hillcrest, Denver Water plans to spend $1.25 billion on 143 capital improvement projects throughout the water system over the next five years.

Those projects include a $400 million state-of-the-art water treatment plant north of Golden, upgrades to the dam at Ralston Reservoir and replacement of a major water delivery pipeline in Jefferson County.
