What to know about water damage in Louisville
1796
The year Louisville became Georgia's first permanent state capital, a role it held for about 10 years. The Jefferson County Courthouse, built in 1904, stands on the site of the old capitol.
The Market House
Louisville's Market House is the town's only remaining 18th-century structure, and much of its original timber is still in place, now reinforced with steel. It has been on the National Register of Historic Places since 1978.
City water and two sewer plants
In the 2004 county plan, Louisville served 1,226 water customers from six storage tanks and treated about 758,000 gallons a day. Its two wastewater plants had a combined permit of 622,000 gallons a day.
Most of the county is on septic
Sewer service is not widespread in Jefferson County. The county turned its water and sewer lines over to the City of Louisville, and much of the unincorporated county uses septic tanks; the 2004 plan counted over 3,000 of them.
