Denver Water is constructing a new ten million gallon finished water tank in Lone Tree


Here’s a report from the Lone Tree Voice (Chris Michlewicz). Click through for the photo slidshow. Here’s an excerpt:

The Denver Water project was delayed two days because of the rainy weather Oct. 8, but sunny skies helped more than 50 workers as the concrete pour got underway just north of Eagle Ridge Elementary School. More than 120 cement trucks backed up to the edge of a deep pit that was excavated in advance of the pour. More than 1,400 cubic yards of concrete will be used on the tank, which is being built adjacent to an existing underground tank near Chaparral Road and Sagebrush Trail. Several community meetings were intended to help surrounding residents understand the size and scope of the project, which is scheduled for completion next summer…

“Because of the current limited storage capacity at the site, Denver Water has made it a priority to increase storage in Lone Tree,” an announcement from the water provider says. The concrete foundation, estimated at 280 feet in diameter, required two concrete batch plants to shut down to other customers for the entire day.

It is the first of eight projects in a $120 million rehabilitation of metro-area plumbing.

Denver Water maintains at least 30 of these underground reservoirs, some holding as much as 25 million gallons, with the system storing 350 million gallons overall. The hidden tanks are a crucial part of making sure that clean water comes out when when 1.3 million Denver Water customers turn on their faucets — even if a pipeline ruptures or a water plant has to shut down.

Paying the $120 million for the fixes over the next decade is expected to boost water bills, which already are increasing by about 5.5 percent a year.
Denver Water officials said there is no way around the re-plumbing because inspectors who went inside emptied reservoirs found enough cracks and infiltration to warrant repairs.

“It’s a big deal. We have to do it. This is the least intrusive we can get,” said Denver Water’s engineering director Robert Mahoney. “This eliminates the risk of us not getting our water.”
