The Gwinnett County Board of Commissioners approved $5.6 million worth of contracts for the replacement of water and sewer lines on July 19th. Twelve miles of aging water lines will be replaced in 15 subdivisions and along residential roads in Hoschton, Lilburn, Norcross, Snellville and Sugar Hill. Over a mile of clogged sewer lines in Lawrenceville will also be replaced. Computerized management and maintenance systems track break history and repair cost so the Gwinnett County Department of Water Resources can decide which water line replacements would be most cost effective. A similar system is used for sewers with a further emphasis on preventing future environmental impacts. The projects are expected to be completed within a year.
