Aqua America, the nation’s second largest water/wastewater utility company headquartered near Philadelphia, announced it is buying Peoples Gas, the nation’s fifth largest natural gas utility company headquartered in Pittsburgh, for $4.275 billion. This story interests us because the buyer, Aqua America, provides services to Marcellus/Utica shale drillers, and because Peoples Gas is a buyer of Marcellus/Utica gas. The combined company will both serve the shale industry as part of the supply chain, and buy the output of the shale industry as a customer. How cool is that? What made Aqua interested in Peoples? It has to do with old pipes in the ground. And similar natures.
