Decatur Waterworks

Decatur Waterworks is a historic water treatment facility spanning about 42 acres with stone structures, tanks, office buildings, and dams along Burnt Fork Creek and South Peachtree Creek. The remaining structures display early engineering work from the start of the 1900s.

The facility was established in 1907 and supplied water to Decatur until the 1940s, when the city's growth outpaced its capacity and operations moved to DeKalb County. During World War II, it played a key role in serving nearby military installations.

The site shows how early engineers managed water supply for a growing community. Visitors can see how stone and concrete structures were woven into the landscape to serve daily needs.

The grounds can be explored through three connected trails starting at Mason Mill Park, featuring a paved path with a bridge over railroad tracks. The site is open to walk freely, and it helps to bring comfortable shoes and water.

During World War II, the facility exclusively supplied a nearby naval air station and army hospital, leading to a temporary closure to the public. This wartime role is a surprising chapter of its history that many visitors overlook.
