In Doraville, DeKalb County Watershed Management supplies water and sewer and sets the backflow rules: commercial and multi-family properties need an assembly matched to their hazard level, tested every year.

Local conditions in Doraville
Doraville grew up around the former General Motors assembly plant and today is one of the region's most diverse cities, with immigrant-owned restaurants, bakeries and markets lining Buford Highway. Its housing and commercial stock is older than most of the metro: the median home dates to 1975, and about 60% of homes predate 1980.
The city's utility links send water service to DeKalb County Watershed Management. DWM's backflow section covers all its customers. Commercial and multi-family properties need an assembly matched to their hazard level, installed on the customer side of the meter by a plumbing contractor holding a Georgia license and tested yearly by a GBPAT-certified tester; the GAWP keeps the list. DeKalb owns the line from the main through the meter, and the owner owns it from the meter to the building.
Doraville's permit process has one detail that catches people out: every permit needs a notarized homeowner or property-owner affidavit, and payment by phone isn't accepted. Plumbing goes on the city's Trade Permit Application, submitted online through Cloudpermit. Tenants should line up the owner's signature early.
Repair or replace?
| Problem | Repair often works when | Replacement makes sense when |
|---|---|---|
| Commercial water heater | A single part fails on a heater still in mid-life | The tank leaks or can't keep up with demand |
| Backflow assembly | A test fails on a check or relief valve | The body is damaged or parts aren't available |
| Cast iron drain line | A single section is cracked | A camera shows scaling and breaks along the run |
| Galvanized supply pipe | One leak at a fitting | Rusty water and low pressure throughout |
Signs to watch for
- A kitchen drain that backs up into a floor sink
- Rusty water at the start of the day
- Restroom toilets that clog repeatedly
- A water heater that rumbles or leaks at the base
- Unanswered backflow test reminders
Timing notes
Schedule drain cleaning for a slow day or before opening. Book the yearly backflow test early, since a failed assembly needs parts and a retest. With Doraville's notarized affidavit requirement, start the permit paperwork for any heater or line replacement before the old equipment quits. Older strip centers along Buford Highway often share one building sewer among several tenants, so a backup in one unit can be caused by grease from the unit next door; tell the plumber who your neighbors are.
