Yakima, WA - Hydrant testing will be going on between 3rd Avenue and 16th Avenue Thursday. During the testing process you may experience rust-colored water. If you do, just keep running the water for a couple of seconds, it will eventually clear up. The city asks for your cooperation in cutting any plants or trees within three feet of fire hydrants located on personal property. That will make it easier for them to access the fire hydrants and make sure that everything is in working order. The city plans to finish hydrant testing by the end of summer.
