The Dalles Public Works Department will be flow testing fire hydrants throughout the city next Wednesday through Friday.  Fire hydrants are flow tested in order to test fire protection water pressures. Motorists and pedestrians are asked to avoid driving or walking through the water coming directly from a hydrant while it is being flow tested.   Occasionally fire hydrant flow testing causes water flowing from a tap to be discolored from stirred up sediment or the water may appear milky white which is caused by tiny air bubbles.  Although discolored water won’t make you sick, flush the pipe by running the water for several minutes before drinking or washing.  If the water does not clear, please contact the Public Works office at 541-296-5401.
