Plumbing behind a county seat that outlived its county
Alpharetta served as the seat of Milton County from its 1858 incorporation until the county dissolved into Fulton County on January 1, 1932. Homes built across that 74-year span typically had plumbing added in stages rather than installed complete on day one, and today Alpharetta draws its water through Fulton County's Chattahoochee River system — treated at the Tom Lowe Atlanta-Fulton County Water Treatment Plant just down the road in neighboring Johns Creek.
Tracing pipe eras across a long county-seat span
A plumber working in one of Alpharetta's original Milton-County-era neighborhoods should expect to trace several generations of pipe material, since the county-seat era ran nearly three-quarters of a century before Fulton County's modern water infrastructure took over.

Mention your home's approximate age relative to Alpharetta's 1858-1932 Milton-County-seat era — older properties often have several generations of pipe material layered together. Add the issue, timing, and access constraints.
Water permitting follows the Fulton system
Because Alpharetta's water runs through Fulton County's Chattahoochee River system, treated at the Tom Lowe plant in neighboring Johns Creek, any plumbing work touching the main supply line or sewer tie-in falls under Fulton County water and sewer permitting on top of the standard building permit.
