The Southern Delivery System will, when completed in 2016, bring 78 million gallons of water a day from the Pueblo Reservoir to Colorado Springs.
Major construction began on the 60-mile pipeline last year.
"Colorado Springs Utilities has been planning on the Southern Delivery System since really the late 80s," SDS spokesperson Janet Rummel said. "It's really going to help insulate us from a drought like we saw in 2002."
It's impossible not to notice the massive project in Pueblo West. Construction crews are feverishly digging trenches to house the pipeline. It's often grueling work, requiring crews to dig into land that is flush with rock.
The project itself is not without controversy. Pueblo District Attorney Bill Thiebault has been one of SDS's most vocal critics.
Recently, a Pueblo judge threw out a state-issued water permit for the project. Colorado Springs Utilities will appeal the decision, but it has so far indicated the ruling will not slow the pace of the ongoing construction.
Reached by phone on Wednesday, Thiebualt told 9NEWS he has lingering doubts about the project and would not rule out asking the courts for an injunction to stop the project in its tracks.
"The real issue here is water quality," he said.
Pueblo city and county officials have long complained about storm water runoff from Colorado Springs entering the county through Fountain Creek.
Thiebault believes the additional water in Colorado Springs will eventually find its way back to his county via the creek and only add to his concerns about the quality of the storm water.
Rummel dismisses the idea adding that the project has been heavily scrutinized for years.
What is clear is that the project is providing much-needed relief for a construction industry that has been hit hard by the economic downturn.
Jared Nessler works for HCP Constructors and is based out of Pueblo West.
"We started working on SDS early in 2011," he said.
This job, he said, is right in his backyard.
