New Chino Valley well may be online by July 4

Chino Valley's new Bright Star Well is expected to be online by July 4, Robin Allen, one of the town's engineers, said Wednesday.

Initially, Ron Grittman, town engineer and Public Works director, had hoped the well would be online by May 7.

The new well is 723 feet deep, and Drill Tech has equipped the well with 12-inch casing of which 160 feet is perforated.

Drill Tech also installed a 125-horsepower submersible pump that will produce 1,150-1,200 gallons per minute (gpm) with no arsenic treatment because initial readings showed less than five parts per billion of arsenic in the water.

Drill Tech's crews had to install a new 440/480-volt three-phase electrical system to provide the required electricity to the well. Grittman said the current electrical system for the Bright Star Tank site wouldn't handle it.

Allen said the electrician had to order an auto transfer switch, which transfers power from the electrical grid to the generator on the pump. "It is supposed to be here this week. The electrician is hoping to install it next week," she said.

Once the electricians install the part and turn the well over to the town, town staff will do an inspection. Then APS will do an inspection. If both inspections pass, the town will apply for approval of a construction permit from the Arizona Department of Environmental Quality, which town staff hopes ADEQ will fast-track.

"If all goes well we're hoping to have it online by July 4th," Allen said.

She said the town's sole water source - the Country West Well, which is located on the east side of Highway 89 and south of Road 2 North - is back to pumping 300 gpm.

"Currently, we have plenty of water in storage to carry us over if something happens to the Country West Well. In case of an emergency, we can react properly," she said.

Allen said it has been an interesting process to watch from start to finish.

"I'm looking forward to the pump getting online," she said.
