Bucks County Water and Sewer Authority Board voted unanimously Wednesday to reject the sale of its sewer system to Aqua PA.

The vote concludes a tumultuous almost two years of negotiations with the private utility company that had offered to pay $1.1 billion for the asset. The proposal, which would have netted Bucks County more than $700 million, ran into stiff opposition from ratepayers and some of the municipalities it serves over fears that the private company would raise sewer service rates substantially to benefit its stockholders.
