Hydrant Flushing?

Despite a general call for water conservation this fire hydrant which I pass on my commute twice each day has been open and flowing freely for the last three. This evening I called the Bedford Police Department to make sure they were aware of the situation. I was informed that this was part of a scheduled hydrant flushing program. After three days it would seem to me that they could have flushed a water line that started in California. Very incongruous to drive past a sign calling for water conservation and then past this scene. Perhaps tomorrow I will move the water conservation sign in front of the hydrant to see if others share my dismay.
