Clarkston's water and sewer are managed by DeKalb County, and the county report doesn't give a hardness figure, so test before buying a softener. Much of the city's housing dates to the 1970s, which makes older pipes and water heaters a common source of trouble. Call the number on this page to be connected with a local plumber in Clarkston.

Clarkston is a small inner-ring city just outside I-285, and its water and sewer are run by DeKalb County Watershed Management, not the city. DeKalb treats Chattahoochee River water at the Scott Candler plant. We found no hardness figure in DeKalb's report. Housing is largely 1970s and 1980s homes and apartments: the median build year is 1979, about 53% predate 1980, and roughly 31% went up in the 1970s alone.
What to do now
- Measure hardness. A strip or a plumber's meter at a cold tap tells you whether a softener is worth discussing.
- Check where color appears. Hot water only usually means the heater; both sides in an older home often means the supply pipe.
- Look up your service line. DeKalb's Check your line tool shows your line's recorded material.
- Decide on taste separately. A carbon cartridge under the kitchen sink is the simplest answer to a disinfectant flavor.
- Plan the permit. Clarkston requires a permit to replace a water heater and for fixture work that alters piping, applied for through the city's SAGES portal.
Symptom and likely cause
| Symptom | Likely cause |
|---|---|
| Brown water that clears after a minute | Corroding galvanized supply pipe |
| Rust tint on hot water only | An aging water heater |
| Chalky crust on fixtures | Hardness minerals, if a test confirms |
| Weak flow at several taps | Narrowed old pipe or a failing regulator |
| Disinfectant flavor | Normal treatment; carbon helps |
What affects cost
- Whether the fix is a filter, a softener, a heater or new pipe
- Condition of the pipe where equipment would tie in
- A drain and outlet within reach
- Permit for work that alters piping
- Ongoing cartridges or salt
Sewage backups on a property are reported to DeKalb County Water and Sewer at 770-621-7200, not the city, since Clarkston handles only storm drains. For a renter, treatment changes need the owner's sign-off, and a pitcher or faucet filter is often the practical choice. For an owner of a 1970s house, the lasting value is usually in fixing the pipe or heater first and adding treatment only if a test still shows a reason for it.
