A boil water order has been issued for the town of Harvard after a distracted driver crashed into a fire hydrant near a high school Saturday night.The crash, which caused a water main break, happened at 8 p.m. in the parking lot of the Bromfield School, according to Harvard police.Video released by police shows water gushing out from the ground near the dislodged hydrant.At about 7:15 a.m., the Harvard Department of Public Works said the town's main water tank was emptied by the broken main.The Massachusetts Department of Environmental Protection later released a boil water order for the town due to the broken main, according to Tim Kilhart of the Harvard Water Department. Residents are being asked not to use any of the town's water until further notice.Kilhart said the town's water tank is slowly being refilled, but residents will have very limited water and could have low water pressure.A member of the Harvard Fire Department will be going door-to-door, distributing drinking water to all residents. It will be at least three days before the DEP will be able to lift the boil water order, Kilhart said.DPW crews worked to repair the broken water main near Bromfield School on Sunday and had the fix completed by the evening.Due to the construction and the boil water order, the Harvard Public School District has canceled classes Monday.The Harvard Police Department is investigating the crash that led to the broken water main.Anyone with questions regarding the town's water service should call 978-456-4130.
