Following reports of cloudy drinking water, city of Vancouver crews flushed water lines in the Ellsworth area Tuesday afternoon. Any sediment that had been in the system should be mostly gone, said Loretta Callahan, a spokeswoman with the city’s public works department.The city believes a problem with an electronic valve caused faster-than-usual flows that stirred up sediment at the bottom of the main water line between about Northwest 97th and Northeast 129th avenues. About a dozen households in the area reported sediment in their water as a result, according to the city. Crews flushed the lines out at hydrants.Nothing in the water posed any health risk, Callahan said.Residents who still see sediment in their water can run an outside faucet or hose for a few minutes to clear it out, Callahan said. They may also call the city’s operations center at 360-696-8177 from 7:30 a.m. to 4:30 p.m. weekdays, or 360-693-9302 after hours.
