I had read somewhere that if the power grid goes down, it is possible that the sewage may back up into your house. Really? A bathtub or kitchen sink full of your neighbors' sewage? That seems so crazy. My house at that time was on the municipal sewer system, so I put on my tin-foil hat (joke) and arranged for a tour of the local sewage treatment plant. Not kidding.
That was a real learning experience, lol. I don't recommend this if one has a weak stomach. If the municipal system uses pumps, which run on electricity, and the power is out for a length of time, yes, that will happen. The system here doesn't use pumps, it is based on a gravity flow system. The treatment equipment, however, does use pumps; they have a propane powered backup that can run for two weeks without a propane refill. It was a HUGE tank! I asked him what would happen if the backup system failed. He said the holding ponds would overflow and the effluent would overflow downhill. I looked in that downhill direction and thought, "Those people in those houses down there may be surprised to know that."
All the waste goes through several different processes, from one "tank" (open air, btw) to another, then to two pond-like areas, where it is allowed to ferment (or whatever they call it). I asked him where it goes from there. Into a local creek downstream! WHAT? He said it is tested before it is released and that it must meet state standards. People fish from that creek. The water goes into a river where it flows into the Colorado River, which serves municipalities and farms in other states. Arizona and California included.
The man who runs the system (by himself, small town) was so very nice and very surprised that I was there. He said NObody had ever asked to tour the place before. He showed me a map of the system, which included the location of my house and explained everything. I was there for over an hour, maybe two?
I sold that house in town and am now in a rural place where I have my own private septic system.
I am on municipal water, however. Perhaps a tour of that is in order?
