Porterdale is a city-sewered mill town. The City of Porterdale Water & Sewer Department bills water and sewer, and all of the city's wastewater goes to NCWSA's Yellow River plant south of town. The pipe under your yard is a private repair; Atlanta Water & Sewage Solutions fixes Porterdale laterals, water lines and septic systems.↗↗↗

The Porterdale story
Porterdale exists because the Yellow River falls 67 feet in half a mile at Cedar Shoals. A first mill went up there in 1835; the big brick ones followed in 1899, 1916 and around 1920. Between 1899 and 1930 the company built nearly 300 bungalows, gabled-ell and saddlebag houses on a tight street grid with small yards and matching setbacks.↗↗
In 1964 the mill sold those houses to the families living in them, and by the 1970s the Porterdale and Welaunee mills had closed. The village is now a 525-acre National Register district. For a plumber or excavator, what matters is that the lots were never laid out for heavy equipment: laterals are short, yards are narrow, and the neighbor's porch is often a few steps away.↗↗
We size the job to the lot. On a Porterdale cottage that usually means a small excavator or hand digging, careful spoil placement on a tarp, and a trench that stays inside your yard.

On the record
Median year homes were built
1938
Typical house here is about 88 years old — and so is its original sewer or septic line.

Housing era
By Census count, half of Porterdale's houses were standing before World War II. That is the oldest median of any Newton County town we serve.
The records do not say what each house's sewer lateral is made of or when it was last replaced. After a century of owners, one cottage may have its original line and the next a modern repair. Expect us to open the pipe and look before we recommend anything.
More about Porterdale
FEMA's flood map puts a Zone AE area, the 1%-annual-chance floodplain, along the river at the Porterdale mill site. Streets that slope down toward the water sit closer to that line than the ones up the hill.↗
High river water does not have to reach your house to cause trouble. Saturated ground around a cracked lateral lets water in, and a line that drains fine in August can gurgle after a week of rain. If slow drains line up with the river rising, tell us; it narrows down where to dig.

Sewer or septic?
The city collects, and the county authority treats. NCWSA's Yellow River Water Reclamation Facility sits on the riverbank south of Porterdale and pumps its treated effluent to 3,000 acres of spray fields on Flat Shoals Road.↗↗
Porterdale has not published where its responsibility for the lateral stops, so for a break near the street we check with the Water & Sewer Department at 2800 Main Street before digging. If your parcel turns out not to be on city sewer at all, GNR's Newton office permits the septic system, and a Level 3 soil report comes first.↗↗

FAQ
Straight answers, with the rule or record behind them. Still unsure? Call and ask the crew that digs.
(678) 863-5620Yes. The City of Porterdale runs a Water & Sewer Department that bills residents for both, and the 2024 One Water Resources Analysis reports that 100% of Porterdale's wastewater flow goes to NCWSA's Yellow River plant. A few outlying parcels could still be on tanks, so check your bill for a sewer charge.
At NCWSA's Yellow River Water Reclamation Facility, on the banks of the river south of the city. Its treated effluent is pumped to about 3,000 acres of spray fields on Flat Shoals Road, according to NCWSA's own description of the plant.

The house side is a private repair, but Porterdale has not published exactly where the city's part begins. Before we dig near the street we confirm it with the Water & Sewer Department at 2800 Main Street, so you are not paying for pipe the city should fix, or waiting on the city for pipe that is yours.

Yes, effective July 1, 2025. The city buys its water from Newton County and said an average customer using about 3,000 gallons a month would pay $13.37 more. With higher rates, an unnoticed leak on the owner's side of the meter now costs more each billing cycle.

FEMA's National Flood Hazard Layer maps a Zone AE, 1%-annual-chance flood area along the river at the mill site. Whether your own lot is inside it depends on its elevation and distance from the bank, so look your address up on the FEMA map before planning any below-grade work.

The company built the village between 1899 and 1930, nearly 300 bungalows, gabled-ell and saddlebag houses on small yards. The Census puts Porterdale's median year built at 1938. Owners bought the houses from the mill in 1964, so repairs since then vary house to house.

GNR Public Health's Newton Environmental Health Department, 1113 Usher Street in Covington. Since February 7, 2022 it has required a Level 3 soil report before any septic permit, repairs included. Near the river, low floodplain ground can limit where a new drain field is allowed to go.
