Multiple waterline breaks in the Colerain area in the past 24 hours have led officials to send a water buffalo to the old Steeple Valley School on Friday morning around 9 a.m.
The Martins Ferry water department said this water is not for drinking, that it is for household use, such as flushing toilets or washing clothes.
Officials say the problem rests with a piece of equipment that's only about a year old, and is affecting 100 houses on County Road 4, from Steeple Valley to West Lawn.
Water pressure is nearly normal during the day, but becomes weak at night when more people are at home, using water.
City crews are working around the clock, and Martins Ferry Service Director Chuck Bennett Chuck Bennett said they are trying to get the part replaced before the weekend.
As of Friday morning, a 48-hour boil order was in effect, which will be extended when the problem is fixed.
