Water treatment plant nearly finished

It won't be long before the new Edward W. Bailey Water Treatment cranks up to filter water coming from Pueblo Reservoir through the Southern Delivery System pipeline.

SDS, the city's $829-million water project, is at the center of a controversy involving Pueblo County commissioners, who want some assurances from Colorado Springs before the pipeline gets activated, which is planned for April. You can read all about those issues in our cover story tomorrow, "On the line."

But in the meantime, a few weeks ago, we got the royal tour of the water treatment facility on Marksheffel Road from two operators — Chad Sell and Jay Hardison — who are as excited as little kids who just got new bicycles for Christmas. They're happy because a redesign of the project placed most treatment processes under one roof, making it not only more efficient but much more convenient to be monitored by Colorado Springs Utilities staff.

SDS project manager John Fredell explains how Utilities got a good deal from bidders: "What we said is, 'We want to see your value engineering ideas right up front.' One said, 'We can shrink this way down, put it all under the same roof and still deliver the same quantity and same quality of water, and we can do this with four miles less piping.' Four miles!"

City staff visited a similar plant in Salt Lake City, and came away eager to have one all their own. Operators loved the idea of a more compact operation, Fredell says.

There's nothing extraordinary really about the Bailey treatment plant, named for a former long-time Utilities water division employee. The plant uses a traditional processes of flocculation, sedimentation and ozone to filter water and deal with any taste and odor problems.

But there are certain design features that take the operators into account. For one thing, the plant can be controlled off-site by an operator using a mobile device. Also, access to the pipes below the various stages of treatment are readily accessible for maintenance and repairs. And, the plant will require only six employees on duty at any given time. It has a 10-million-gallon holding tank.

The plant is built so that it can be easily expanded from 50 million gallons a day to 100 million gallons, Hardison notes. "Here’s a pad for a future generator," he says. "We can add another generator and go to 100, like for our great grandkids."

While the whole system could become operational within just a few months, for now, operators are running it through the rinse cycle to be sure all is in working order. "So we're currently testing all the processes out," Hardison says. "We're stopping and starting the plant, trying to get it fine-tuned. Plants run really well when they’re run all the time, continuously. If you stop and start, they’re not very good. We’re almost to the point where we will run it continuously."

He adds that one thing operators will learn during the testing is the "bookends of the low end and high end" of what the plant is capable of.
