Power line project can’t soar past Willcox water woes

A helicopter with a worker dangling beneath it buzzed among a row of newly built transmission towers north of Willcox last Sunday as construction continued on a multi-billion-dollar wind-energy power line through Southern Arizona.But it was another aspect of the SunZia project that had Willcox officials worried earlier this year.In May, water stopped flowing from one of the two municipal wells used to supply more than 1,500 residents of the farming and ranching community about 85 miles east of Tucson.A city consultant soon traced the problem to pumping from a nearby commercial well that was supplying water for the construction of the power line.
