Generally, a lot must be at least 30,000 sf (approximately 0.7 acre) and have 100 feet of frontage to qualify for a private septic system. Rebuilding of existing systems on non-conforming lots may be allowed.If a public sewer exists 200 feet or less from the property, or 500 feet or less from a residence, a septic tank is not allowed, and that residence must connect to the public sewer. Septic tanks are not allowed for commercial development. To determine the available options for connecting to the City of Atlanta’s sanitary sewer system, contact the Department of Watershed Management, Site Development, at 404-330-6249.This Article was created on: 02/23/2014This Article was last updated on: 09/23/2020
