Sewer and water pipes across the nation are breaking -- creating a record number of sinkholes.
"Bad sewer pipes created this sinkhole. And the problem is getting worse, around the world and in the United States. Last year was the worst ever in the U.S. for sinkholes. Almost every state in the country experienced record problems...Most water and sewer pipes in the United States were built 60 years ago - but were meant to last 50 years. Do the math. Pipes are breaking as they get older...When pipes break, two things happen: Water or sewage gets out, and water or dirt gets in. Havoc results when dirt enters a broken pipe and is whisked away, as though on a magic carpet ride. Soon, even if only by a spoonful a day, the dirt disappears from above the pipe and below the sidewalk - or below the road, park, building, etc."
