Atlanta proposal would write a broad septic ban into city code

A proposed Atlanta ban on septic systems is broader than its “commercial development” label suggests: it would cover all new public and private development except single-family and two-family dwellings.⁠[1]

The City Utilities Committee’s Oct. 13 agenda lists that proposal for first reading at its 10 a.m. meeting. Also on the held docket is a separate proposal defining when sewer service counts as available—and when a development must connect. These are two pending proceedings, not an approved package of sewer rules.⁠[1][2]

The septic-ban ordinance, 26-O-1583, would require every new development meeting its broad definition to connect to public sewer. It would prohibit construction of septic tanks and other private sewage-disposal facilities serving those developments. Its operative language contains no exception based on how far away the public sewer lies.⁠[1]

The ordinance frames this as clarifying a “long-standing policy” against septic tanks for commercial development. It argues that public sewer provides better wastewater treatment and environmental protection. Those are the proposal’s stated reasons; the records reviewed do not independently establish how the existing policy has been applied.⁠[1]

The held proposal, 26-O-1340, takes a different approach. It would count sewer as available when a public line lies within 200 feet of any property line or 500 feet of existing or proposed premises, measured along the appropriate drainage course for gravity flow. A building being too low for a direct connection would not by itself establish unavailability: sewer would still count as available if pumping could reach part of the property that drains into the public system by gravity.⁠[1]

Under that draft, new residential and commercial development would have to connect when sewer is available. Where it is unavailable, septic systems could be used—but expressly subject to other city ordinances, state laws and county rules. That qualification matters: the draft does not offer an unconditional right to install septic. It also would allow pumping within a parcel while requiring the connection to public sewer to use gravity flow.⁠[1]

Both drafts propose putting their language in Section 154-156 of the city code. Their different wording does not establish that one replaces the other, and the reviewed records do not resolve how the provisions would be reconciled if both advance.⁠[1]

The legislative history records that full Council returned the availability measure to committee as held on Oct. 5. The septic-ban proposal’s workflow also marks committee consideration as pending. The Oct. 13 agenda therefore provides a checkpoint, not evidence of adoption or a guarantee of a final vote; the ban’s text requires Council adoption and mayoral approval before taking effect.⁠[1][2]
