A state-of-the-art pump station started work Tuesday, marking Charlotte Water's first push past Mecklenburg County lines into Mount Holly. Drawing from Mountain Island Lake, this facility meets rising water demands in the fast-growing region. Charlotte Water said per Queen City News. The town's old system, which also pulled from Mountain Island Lake, now gives way to modern methods. After years of staying within Mecklenburg's borders, Charlotte Water now stretches its reach.
