LAWRENCEVILLE -- Twelve miles of aging water mains and more than a mile of old, frequently clogged sewer lines will be replaced under contracts approved this week by the Gwinnett County Board of Commissioners.
The water mains run through 15 subdivisions and along key sections of residential roads in and around Snellville, Lilburn, Norcross, Hoschton and Sugar Hill, according to a news release. The old sewer lines are in Lawrenceville.
Computerized management and maintenance systems track break history and repair costs to help the Gwinnett County Department of Water Resources decide which water line replacements would be most cost effective, the news release states. A similar system is used for sewers with a focus on preventing future environmental impacts.
All of the projects will be funded through the county's water and sewer renewal and extension fund.
John D. Stephens Inc. of Lawrenceville was the low bidder at $933,102 to run new eight-inch ductile iron water lines within the Trotters Pointe, Valley Brook, Cumberland Forest and Windsor Estates subdivisions.
GS Construction Inc. of Lawrenceville was the low bidder on two similar water main projects. Streets affected include work along Sudderth Road, Mineral Springs Road and within the Quail Hollow East, Glynn Mill, Chattahoochee Station, Marcelle Heights, Kings Lea and Pine Pavilion Estates subdivisions. The total bid for both projects was just under $2 million.
Kemi Construction Inc. was the low bidder at under $1.5 million to install new water lines within the Smoke Rise, Timber Trace, McCart Estates, Danbury and Lockridge Forest subdivisions.
The Ezzard Road sewer project will replace about 3,500 feet of deteriorated eight- and 10-inch pipe and install 5,450 feet of 16-inch and 18-inch ductile iron gravity sewer pipe. John D. Stephens Inc. was the low bidder at about $1.2 million.
The project also includes decommissioning two sewage pump stations that will no longer be needed.
"We like to see this happen whenever pump stations have reached the end of their life cycles in order to help mitigate the rising costs associated with maintaining these systems," Deputy Operations Director Tyler Richards said.
Water Resources Field Operations Director Jeff Boss said residents in the affected areas will get more information on anticipated shutdowns from the department soon. The projects are expected to be completed within a year.
