Who handles sewer and water line problems in Dunwoody, GA?
Dunwoody's public water and sewer belong to DeKalb County Watershed Management; spills and main breaks go to DeKalb's emergency line, 770-270-6243. Past the meter and inside your property line, the pipes are the owner's. We repair those private sewer laterals and water service lines for Dunwoody homes, many built in the 1970s.↗↗↗

Median year homes were built
1984
Typical house here is about 42 years old — and so is its original sewer or septic line.

Housing era
A city that went up all at once
Dunwoody stayed farm country until suburban building started in the 1960s. Then it arrived fast. In 1971 the Spruill family sold a large tract for Perimeter Mall, and Dunwoody Village, with its Colonial Williamsburg storefronts, opened the same year.↗
The census still shows that burst. Of 23,491 housing units, 6,548 were built in the 1970s, about 28 percent and more than any other decade. Another 3,197 date from the 1960s. The median home was built in 1984.↗
When thousands of houses are plumbed in the same few years, their private lines age on the same clock. Laterals and water service pipes from that era are now around fifty years old, and the trees planted beside them have had half a century to find every joint.

The Dunwoody story
DeKalb is already digging up the 1950s
The county's own records show what fifty-plus years does to pipe here. Water mains laid in 1955 along Chamblee Dunwoody Road, with others added in the 1970s, broke 49 times between 1989 and 2024. DeKalb's Dunwoody Knoll project replaces them with roughly 10,800 feet of 8-inch and 1,100 feet of 12-inch ductile iron main, including new service lines, along Chamblee Dunwoody, Roberts Road, the Fairfield streets and Dunwoody Knoll Drive and Court.↗
County work stops at the meter. When a main is replaced, the pipe from the meter to your house stays as it was, and a fresh connection can expose a weak or leaking private line. That is often when owners first call us.↗

Soil & terrain
Steep lots change how a Dunwoody dig goes
The USDA maps the middle of Dunwoody as Pacolet-Urban land complex on 10 to 25 percent slopes, about two-thirds well-drained Pacolet and one-third ground already paved or built over. Lots fall hard toward the creeks, so a lateral can run shallow at the house and deep at the street, or the reverse.↗
Pacolet is very deep, with a firm red clay subsoil from a few inches down to about two and a half feet and bedrock more than 60 inches below. Rock is rarely the problem; wet clay on a slope is. We shore or bench deeper cuts and place spoil so it can't slide toward a neighbor's yard.↗

Sewer or septic?
Septic in Dunwoody?
You will see septic companies advertise here, but we could not find a public record showing septic inside city limits, so we don't build septic pages for Dunwoody. If you suspect an old tank on your lot, we can locate it before you buy or build.

FAQ
Dunwoody homeowners ask
Straight answers, with the rule or record behind them. Still unsure? Call and ask the crew that digs.
(678) 863-5620Who do I call about a sewer spill or water main leak in Dunwoody?
DeKalb Water and Sewer emergencies at 770-270-6243. The city's trouble-calls guide routes water main leaks, sewer spills, brown water and loss of water there.
Why do Dunwoody water mains keep breaking?
Age. DeKalb says mains along Chamblee Dunwoody Road were installed in 1955 and broke 49 times from 1989 to 2024, which is why it is replacing them.
Does DeKalb's main replacement fix my pipe too?
Only up to the meter. The county owns the system through the meter; the line from the meter into the house is the owner's.
Why are so many Dunwoody sewer lines failing now?
About 28 percent of the city's homes were built in the 1970s, so a large share of private laterals are roughly fifty years old at the same time.

Does a steep lot make repair harder?
It can. Central Dunwoody is mapped on 10 to 25 percent slopes, so trench depth, shoring and spoil placement take more planning than on flat ground.

Is my Dunwoody house on septic?
Almost certainly not; we found no primary source showing septic inside the city. A DeKalb sewer charge on your bill confirms it.
