Way back in November Danny Adler wrote an article for the Bucks County Courier Times, "Murphy pushes for anti-flooding device," (11/27), on proposed funding for backflow preventers in the Rivermawr section of Yardley. Wondering what a backflow preventer is? According to the article:
The devices will prevent water from backing up through the drainage system out onto the streets and into homes in Rivermawr, officials said. After a 22-foot flood, though, the backflow preventers won't do much, officials said.
