A 10-inch PVC water main split lengthwise at about 12:10 a.m. along 116th Way NE, north of the Kingsgate park-and-ride entrance in Kirkland.
The break sent water gushing down 116th Way - but the location of the break kept damage to a minimum. The water passed by an apartment complex and collected under an overpass before draining away.
The volume of water did cause part of the roadway to buckle, but no customers lost water service.
"We were actually able to isolate this," says Alan Nelson of the Northshore Utility District. "No customers are affected by this right now, so we have nobody without water."
Utility officials said the district was notified of the leak at about 12:30 a.m. and was able to isolate the broken main by 1:10 a.m. A repair crew was on site by 2:30 a.m.
Repairs were completed by about 7:30 a.m. and 116th Way was reopened between NE 132nd Street and the Kingsgate park-and-ride.
Water customers in the area may see some temporary discoloration, but the water remains safe to drink, Nelson said. He said customers should run the cold water at the highest part of their property for 10 to 15 minutes or until water runs clean. If "dirty" water persists, they should contact the district office at (425) 398-4400.
