Every year, right around the week of Thanksgiving, our phone starts ringing with the same story. The house in Milton or Johns Creek is full. Cousins in the guest room, kids on air mattresses, a turkey in the oven and a sink full of pans. Then somebody notices the downstairs toilet gurgling, or the shower drain won’t empty. A septic system that worked fine for a family of four is suddenly trying to keep up with twelve.
Good news: you don’t have to cancel the gathering. You just have to give your tank a little help. Here’s how we tell our customers in Alpharetta, Roswell and Cumming to get ready.
Why a Full House Hits Your Tank So Hard
Your septic tank works on time. Wastewater comes in, solids settle to the bottom, grease floats to the top, and the clearer liquid in the middle moves out to the drain field. That settling only happens if the water sits in the tank long enough.
The EPA puts typical indoor use at up to 70 gallons per person per day. Add six or eight guests for a long weekend and you can double what your system normally sees. Water rushes through faster, solids get pushed toward the outlet, and the drain field gets more than it can soak up. Here in North Georgia, with our tight red clay, that soil already drains slower than you’d like.
Before Everyone Arrives
The best thing you can do happens a few weeks out, not the morning of.
- Think about your last pumping. Most household tanks need it every three to five years. If you’re at the edge of that window, or you can’t remember the last time, get it done before the holidays, not after.
- Fix that running toilet. A single leaky toilet can waste up to 200 gallons a day. That’s a lot of extra water your system doesn’t need on its busiest week.
- Keep the drain field clear. Don’t let guests park on it. The weight of a car packs the soil down and can crack the pipes underneath. If you need overflow parking, put out a few cones or point folks to the street.
- Check where your gutters drain. Late fall rain plus a full house is a hard combination. Downspouts should send water away from the field, not onto it.
While They’re Staying With You
- Spread out the laundry. Doing every load in one day can flood the drain field. Run one or two a day instead of six on Saturday, and only run full loads.
- Space out the showers. If you can, have some folks shower at night and some in the morning so the tank isn’t taking it all at once.
- Run the dishwasher full. Scrape plates into the trash first. Go easy on the garbage disposal, since every scrap it grinds ends up as solids in your tank.
- Put a small trash can in each bathroom. Guests don’t always know your house is on septic. Wipes, even the ones labeled flushable, along with feminine products and paper towels belong in the can, not the toilet.
The Turkey Grease Problem
This is the big one. After the meal, someone always wants to pour the roasting pan down the sink with a little hot water. Please don’t. Cooking grease, butter and gravy cool and harden in your pipes and add to the scum layer in your tank. Let it cool, pour it into an old can or jar, and toss it in the trash.
Signs Your System Is Struggling
Keep an eye out for these during the visit:
- Gurgling sounds in drains or toilets
- Sinks and tubs draining slower than normal
- A sewage smell near the tank or in the yard
- Wet, spongy ground over the drain field
If you notice any of these, ease off the water right away. Hold the laundry, keep showers short, and give the tank a chance to catch up. If things don’t settle down, that’s the time to call us. We’re open every day from 7 a.m. to 10 p.m., and we handle emergencies across North Fulton.
