01Milton is on Fulton County water
Fulton County's lead and copper page says its North Fulton Water Distribution System includes all of Milton, along with all of Alpharetta and Johns Creek and most of Roswell. The County's billing division lists Milton in its north Fulton service area. That means Milton households follow the County's rules for emergencies, billing, leak credits and backflow, and the guides across this site apply in Milton.
Some properties in the area may draw water from a private well rather than the County. Fulton County's backflow policy treats a property with County water and a well, active or inactive, as a higher hazard class, which is worth knowing if your property has both.
02Who to call
For a water main break, a leak at the meter or another drinking water emergency, Fulton County lists 770-640-3040 for areas north of the Chattahoochee River. For a sewer overflow from a public line, the County lists 404-612-3061 for north Fulton, including after hours. For billing questions, it lists 404-612-6830.
Fulton County says it owns the water line from the main to the meter and the owner owns the line from the meter to the building. Its lateral flyer says the owner is also responsible for the sewer lateral to the property line. Problems on your side go to a licensed plumber; see the emergency steps.
03Summer bills and irrigation
Fulton County bills residential water in three tiers from April through October, based on your winter average from November through March. In 2026, Tier 1 is $4.74, Tier 2 $5.91 and Tier 3 $9.47 per 1,000 gallons, and sewer volume is $8.98 per 1,000 gallons. Outdoor use in summer can push usage into the higher tiers, and a leak on top of irrigation does the same.
Our leak cost calculator estimates the added cost of a measured leak, and the high bill guide explains the tiers. Fulton County also publishes a separate irrigation meter rate of $9.47 per 1,000 gallons in 2026.

Fulton County's backflow policy classes irrigation and sprinkler systems as medium hazard, requires at least a double check backflow preventer, and requires testing at installation and at least annually by a certified tester who submits results through SwiftComply. Georgia EPD limits outdoor watering of established landscapes to between 4 p.m. and 10 a.m. for customers of EPD-permitted systems.
Our Milton irrigation, backflow and watering guide covers both in detail, including the EPD exemptions for new landscapes, drip irrigation and hand watering.
05Permits and licenses
Milton issues its own building and trade permits through the City of Milton's Community Development department. We could not verify Milton's current permit pages for this guide, so ask the City or your plumber which permit a repair needs before work starts. Neighbouring Alpharetta's rules, explained in plumbing permits in Alpharetta, are not Milton's.
Statewide, Georgia requires anyone performing plumbing for hire to be licensed. The Secretary of State says a Class I Master Plumber may work on single-family dwellings and a Class II Master Plumber has no restrictions; see license checks.
06Leaks and credits
Fulton County's meter test, in our leak detection guide, tells you whether a leak is inside the house or in the yard line. Once a qualifying leak is repaired, the County accepts leak adjustment requests with the plumber's repair bill; see leak adjustments.
