Aqua America has regularly backed dozens of Pennsylvania political candidates financially since 2005. The company has spent $153,750 on contributions to state and local candidates this year alone, according to the Center for Responsive Politics. Last week, the company announced it would purchase Peoples Gas for $4.3 billion.

Both companies have been eyeing the struggling Pittsburgh Water and Sewer Authority, and have expressed interest in providing water to the city.
