So we have a septic system which has an aerator which has obviously not been on since Sunday afternoon. So I guess all my bacteria is dying or dead. What needs to be done during the outage? We are not using toilets, sinks or showers. What needs to be done after? I’m seeing conflicting information about using rid-x or similar additives to get the system back healthy. Please help, the last thing I need is some kind of major bill to fix something I neglected.

The aerator isn't really necessary and it's not a big deal for it to be off for a few days or weeks even.

The only issue you could run into at all right now probably depends on how the system handles gray water. If it pumps it off somewhere you'll want to run the pump off a generator for a few minutes every day or two just to clear out the gray water. If it uses a drain field then you should be good.

I am 99% sure it uses a drain field. The only power I believe that goes to any part of it is the aerator.

Should be ok. When we first moved into our previous home, no one told me anything about these aerators, always lived on city sewers. Ours was unplugged for a solid couple months. Granted it was empty, but still.

You'll be ok for a few days.

Been in my house with septic tank for 19 years and never had an aerator…put some rid-x down the toilet every 6 months or when I remember and never had issues or had it pumped out, FWIW

Damn, and I thought they had to be pumped every so often.

I never hooked my up. It has been working fine since 2003. Every time you flush the toilet it adds oxygen (I think).

Every home in my community is on septic and barely anyone has aerators. Your bacteria are fine.

We get our inspected and pumped if needed every 3 years, but I have 4 kids.

Septic systems don’t have aerators. Septic is a term in wastewater treatment used to describe a bacterial environment where there is no dissolved oxygen and the metabolic pathways used to destroy organics and produce energy are of the fermentative nature. What you have is a treatment system that relies on aerobic degradation if organic and nitrogen containing material.

Treatment systems are generally smaller than septic because the aeration acts to stir/mix the wastewater allowing for better contact of the bacteria to the material, while septic is unmixed and you need things to settle out to be degraded.

Most bacteria in sewage treatment units can operate in either aerobic or septic conditions, it just takes some time to switch metabolic pathways.

Your system should be fine if it’s a couple of days/a week, but get the aerator on as soon as possible as the smaller residence time will result in less complete treatment.

It may not fill up but you’re discharging un/under treated waste

Thanks man, so with this said, I obviously have no control over when it comes back on, so is there anything I need to do to ‘jumpstart’ it back to normalcy when I do get power back? It could be another week.
