South Fulton, GA Water Use Rules: Recycled Water Rules (2026)

South Fulton's recycled-water rule sits inside the Subdivision Regulations' water supply article, alongside the standard potable water main requirements. Section 9.3.1 already requires a subdivider to extend public water mains and connect to any public water supply within 300 feet of the development, and Section 9.3.4 sets fire hydrant main sizing at a minimum 8-inch diameter. Section 9.3.5 adds a parallel non-potable system: when the Department of Public Works determines a reuse water irrigation distribution system is needed, the subdivider must install one to every lot in the subdivision, not just to common areas.

The specification is exact. The reuse main must be 8-inch diameter ductile iron pipe, labeled non-potable water and painted purple, the standard color code for reclaimed water lines, so contractors and future excavators can distinguish it from the drinking-water main. The regulation also fixes where the pipe goes: it must be installed on the south or east shoulder of the right-of-way limit, keeping it on a consistent, predictable side of the street across the subdivision. Every component, pipe and appurtenances alike, has to meet the City's own Water Reuse Standards, a separate technical document the Public Works Department maintains.

The connection obligation runs to individual property owners, not just the developer. Once the reuse main is activated, any owner who wants an irrigation meter for landscape watering has to connect to that non-potable main rather than run irrigation off the potable water system, tying recycled water use to irrigation demand and off the drinking-water side of the utility.
