The Milford Water Company shut off water to more than 100 customers, including Acapulcos restaurant, after a 10-inch main broke late Tuesday morning.
Repair of the cast iron main was delayed for several hours while the Water Company waited on a gas utility to arrive, to identify the location of a high-pressure gas main in the area, said Water Company manager David Condrey.
The location of the break was on East Main Street, near the Holliston line. The break was reported to 911 by several callers about 11 a.m. Tuesday.
At 3:30 p.m., Condrey estimated the repair would take several more hours, possibly as many as five to six hours. If the water stoppage was more prolonged than that, he said he could move water into Milford from Holliston.
The break needs to be evaluated, he said, but likely resulted from changing temperatures in the soil, which causes shifting.
Once water is restored, he said, customers will need to flush the faucets because discoloration will occur.
Acapulcos has temporarily closed as a result of the water shut-off. The restaurant was the only food-serving establishment affected by the shut-off Condrey said.
The water was shut off to 10 to 15 fire hydrants in the area, said Fire Chief John Touhey, generally from Fortune Boulevard east to the Holliston line. In the absense of water from hydrants, he said, two tanker trucks that are used for fighting brush fires have been activated, along with two additional firefighters.
The brush trucks have a combined capacity of 2,800 gallons, he said, and will supplement the Fire Department's existing tanker trucks in the event of a structure fire. The Holliston and Hopkinton fire departments also have been notified, Touhey said, and could assist if needed.
