Frisco upgrades water treatment facility in $4.4 million project
On Tuesday, weather permitting, workers will use a crane to lift and move the 29,000-pound dome off the water treatment plant next to Highway 9 just south of Frisco’s Main Street.
The Frisco Sanitation District, with the help of Fort Collins contractor Hydro Construction Co., is opening up the plant this winter as part of a $4.4 million project to meet new regulations required by September 2016.
Under the dome, which is 100 feet wide and 15 feet deep, are steel tanks that were installed in 1975, said Butch Green, district manager.
“Steel tanks in the wastewater business are good for about 20 years,” he said. “We’ve been sandblasting and painting them every year to squeeze as much life out of them as we can get, but they’re lifeless now.”
The tanks will be replaced with concrete ones, which should last 40 to 60 years, he said.
This most difficult part of the project should be finished next summer, and until then, Green said he’ll be on edge hoping the system works with half its equipment in operation.
“The tricky part is you can’t make a mistake or break anything,” he said.
That’s why the sanitation district already upgraded the digester, the part of the treatment plant that will handle the increased workload, and fixed or replaced everything that could fail.
The project also entails constructing a wetlands area to meet stricter requirements for ammonia and total nitrogen treatment.
