We don’t, at least not yet, we haven’t lived here long enough to have to have dealt with it. That is a good idea though, we can see who the neighbors use.
My assumption would be it’s for airation. I’ve seen pipes like that before and have no idea why they are so high off the ground.
I know someone who has a septic tank with an airation appliance. It’s basically a dog house with AC power and an airator on a timer that you can hear periodically turn on. Perhaps that’s an alternative. I would figure an electronic appliance would more effectively air out the septic.
