Water surged out of the ground and onto the street at 11th Avenue NE and NE 75th Street at around 9 p.m. Thursday.
Fire crews responded to the break in a 6-inch line, but it took about an hour for Seattle Public Utilities crews to shut off the water.
The flood mostly impacted the street. There were some homes near the path of the water, but they were spared any damage.
Workers worked on fixing the leak all night so people in this area would have water Friday morning.
Eight to 10 customers and three fire hydrants were without water overnight, but are now back in service.
