Aqua Pennsylvania, the state operating subsidiary of Bryn Mawr-based Aqua America Inc., announced Wednesday it will spend $230 million in infrastructure improvements in 2014, compared to $216 million in 2013.

About $124 million will be spent in Bucks, Chester, Delaware and Montgomery counties.

Infrastructure improvements are critical to maintaining aging water systems, but also to improving a utility's earnings, since they typically are allowed to recover the costs from ratepayers.
