Testing Program Application

Woodinville Water District offers residential backflow customers an option to have the District perform the backflow test and the charge added to their next water bill. Fill out the form which allows the District to take care of this task for you.  The State of Washington requires the backflow testing yearly and the District is responsible to ensure the testing is done (WAC 246-290-490).
