BETHESDA, Md. -- As much as we like to blame the weather for our water main breaks, the massive rupture that turned a Bethesda road into a raging river was caused by an incorrectly installed pipe, according to a report.
The December water main break sent a wave of water down River Road, trapping motorists in their cars who had to be rescued by helicopters and boats.
A forensic analysis released Wednesday found that the 66-inch pipe was installed directly against a rock, which led to cracks and corrosion. The contractor that installed the pipe 44 years ago failed to cushion it in a bed of gravel, the report said.
