Aquarion Water Company will be cleaning the water mains in Bethel's Chimney Heights System from Sunday, through May 29. The work will be performed between 9PM and 5AM Sunday through Thursday nights.  This project should last approximately two weeks and, during that time, residents might notice some was  discoloration, which results from the temporary disturbance of the water flow.  The work can stir up naturally occurring minerals that settle in water mains.  Delay washing clothing until the water is clear.  Residents are encouraged to store tap water in the refrigerator ahead of time for drinking and cooking.
