UPDATE: Water service has now been restored for all customers except those on the 900 block of Acewood Blvd., which has been valved off for repairs. Repairs will likely take several hours.

Madison Water Utility us working to isolate a very large main break on Cottage Grove Rd. at Acewood. The break is at the intersection of two 8-inch mains.

Customers in the immediate one or two block area are currently without water. We have reports that part of Acewood is beginning to buckle, so people should stay clear of the area if they can.

We should have the break isolated and water back on for affected customers within an hour, but repairs to the broken main could take much of the day.
