A broken water main at the Brightwater treatment plant construction site caused no apparent property damage or environmental impacts according to county construction crews who inspected the area early this morning.
Crews were called to respond shortly after midnight to a broken 6-inch water main at the intersection of Northeast 228th street and State Route 9 north of Woodinville. The temporary line supplies water to the Brightwater site during construction. The broken line was shut off about 1 a.m.
The Washington State Patrol temporarily closed one northbound lane of SR-9 as a safety precaution, and reopened the roadway at about 1:30 a.m. The incident caused no water service interruptions to nearby homes or businesses.
It’s estimated that about 30,000 gallons of water from the broken pipe flowed onto the northbound lane of SR-9 before entering four catch basins operated by Washington State Department of Transportation, eventually settling into a swale on the east side of the road. Environmental inspection crews reported no sediment deposition or impacts to Little Bear Creek.
Vactor trucks were deployed to remove debris from the catch basins, and the incident was reported to the state Department of Ecology.
The cause of the break is under investigation.
