This might be a silly question, but is it normal for septic systems to make noise? I’ve started noticing a low humming or buzzing sound from the yard, especially at night when it’s quiet. At first I thought it was a neighbor’s AC unit, but I followed the sound and it’s definitely coming from my septic system area. It’s not super loud, but I can hear it through the window sometimes. Is that normal operation, or is it a sign something is about to go wrong?

Not a silly question at all – I wondered the same thing when I moved into my house. Some noise is actually normal, especially if you have an aerator or pump. They do hum while they’re working. What you want to watch for is if the noise changes – gets louder, starts grinding, or sounds irregular. That’s a red flag. When my old aerator started buzzing like crazy, I swapped it out for a quieter, more efficient model from https://septicsolutionsllc.com It solved the noise issue and gave me peace of mind knowing it wasn’t about to fail. So a little humming is fine, but keep an ear out for changes.
