The Water Division performs approximately 1,200 back flow inspections per year at commercial and industrial businesses to protect the water distribution system from non-potable sources. Other primary functions of the Water Division include ensuring water quality by routine testing and performing emergency repairs to the distribution system. Completed projects during FY08 include the installation of a water main on Concord Road between Davis Road and the Concord town line.
