Battery Backups and Alarms
A sump is a lined pit at the low point of a basement floor, fed by drain tile or the gravel under the slab. As water rises, a float starts the pump, which lifts it through a pipe to the outdoors, while a one-way check valve keeps it from draining back. A pump moves only what reaches it, so nobody can promise a basement that never gets wet.
A battery-powered second pump can take over during an outage or a motor failure, and a high-water alarm sounds when the pit fills too far. Georgia's State Climatologist reported 11.12 inches of rain in 48 hours in Atlanta, GA during Hurricane Helene in September 2024, the most in records going back to 1878; that is a good reason to test the pump.
Red clay subsoils, common across the Georgia Piedmont, give up water slowly, so a pit can keep filling for days. Older basements may lack a pit; newer ones wear as motors fail, floats stick and outlets clog.
No discharge rule for the City of Atlanta, DeKalb County or the five nearby towns turned up, so ask your city or county where yours should go; meanwhile, send the water onto open ground outdoors, clear of the foundation and the neighbors, keeping it out of floor drains, laundry tubs, sewer cleanouts and the sanitary sewer.
Running a sump line into household plumbing, a drain or the sewer belongs to a Georgia-licensed plumber working under a plumbing permit. The City of Atlanta issues those permits separately ((404) 865-8550), unincorporated DeKalb takes them only from licensed plumbing contractors, and Avondale Estates, GA wants a separate trade permit regardless of value. A new circuit or outlet for the pump is electrical work, and a licensed electrician with an electrical permit may be needed.
The Usual Scenarios
- No pit at all. Water creeps in where the wall meets the floor, with no low point to collect it.
- A worn-out pump. The motor hums without moving water or clicks on and off in short bursts.
- No backup or alarm. Nothing steps in if the main pump stalls during a long, soaking rain.
The Typical Job, in Order
After a contractor gets in touch, the work usually runs:
- The contractor's own visit. It sets up the visit and writes an estimate naming the pit, pump, valve, any backup or alarm, and the outdoor outlet.
- Permits and other trades first. Permit needs depend on scope and address, so the contractor confirms them before work starts (at a City of Atlanta address, with the Office of Buildings, (404) 330-6150), plus any historic-district review; a plumbing tie-in waits for a Georgia-licensed plumber.
- Cutting the pit. The floor is opened at the low spot and the basin set on gravel, then sealed in.
- A trial run. Water poured into the basin should start the pump and leave the house through the new pipe.
Budgeting for Sump Pump Installation
| Cost row | Figure | Source (year) |
|---|---|---|
| Typical basement waterproofing project | about $3,000 to $10,000 (average about $5,000) | Fixr national (2026) |
| Interior perimeter drain, per linear foot | $40 to $120 | Fixr national (2026) |
| Sump pump installation | $600 to $2,500 | Fixr national (2026) |
| Epoxy crack injection, per crack | $250 to $1,000 | Fixr national (2026) |
| Waterproof paint or sealant, per sq ft | $1 to $8 | Fixr national (2026) |
These are Fixr's national 2026 figures; no Atlanta, GA or Georgia price source was read. A new pump in a working pit usually costs less than a first pit. Plumbing tie-ins are priced by a licensed plumber. No City of Atlanta, DeKalb or town program that helps pay for sump work was found (see the Georgia rules page).

Why One Contact Is Enough
One request means one independent contractor reaches out, not a string of strangers, and its estimate is its own. Basement Waterproofing Atlanta GA only refers and advertises; it is no kind of contractor, plumber or electrician, holds no residential or general contractor license and no plumbing license, and adds no inspections, prices, discounts or gifts. Contractors may pay it a flat advertising fee, a free trial at present, that never hinges on whether work follows.
You still do the checking, and nothing stops you asking other contractors too. Ask which Georgia license, if any, the job needs, confirm it, the business license and insurance certificates yourself, and pay as the work moves along.
Frequently Asked Questions
Does a sump pump do the job of a backwater valve?
No. A sump pump lifts groundwater from a floor pit to the outdoors; a backwater valve is fitted to the house's outgoing sewer pipe and shuts if sewage flows backward. Fitting a valve is plumbing: ask a Georgia-licensed plumber whether your home suits one, and the plumber pulls the permit.
What if water comes up through a floor drain instead?
That points to a sewer backup, which a sump won't solve. Report it to ATL311, 404-546-0311, at a City of Atlanta address; DeKalb Watershed Management at 770-270-6243 in Druid Hills, Candler-McAfee and Avondale Estates, GA; Water & Sewer at (404) 474-3834, or (404) 240-2183 after hours, in East Point, GA; and City Hall, 404-669-2100, in Hapeville, GA.
