Hydrant Testing

Fire hydrants at the following locations will be flow tested.  These tests are important because it helps us ensure that the water system is working properly and that the hydrants will provide the water needed in case of fire.  During testing and for a short time afterwards, you may experience dirt or rust in your water.  This is normal and is a temporary situation and will clear up soon after the testing is completed.


Please check the condition of your water prior to using your washing machine.
