A leak in a major water supply line to Santa Rosa ran for approximately five hours Monday afternoon, before it was repaired.
Drinking water was released at a rate of 10-gallons per minute during that time. According to the Sonoma County Water Agency, the chlorinated water was contained in a field and did not enter creeks or waterways.
The leak occurred at about 1:30 pm when a contractor for PG&E accidentally hit the Water Agency's Kawana aqueduct pipeline with heavy equipment, while working in West Santa Rosa near the intersection of Brittain Lane and the Joe Rodota Trail.
The contractor notified the Water Agency about the leak, and crews from the Water Agency and the City of Santa Rosa responded immediately to isolate the damaged pipe and repair the problem. The leak was stopped at approximately 6:30 p.m. There were no interruptions to water service.
The 6 ½ mile-long Kawana aqueduct is one of a series of large pipelines that deliver naturally filtered Russian River water to more than 600,000 residents in portions of Sonoma and Marin counties.
