Sump Water To Sanitary Sewer

cleveman

I currently have my sump pump connected to the sanitary sewer with a battery back-up pump.

I would prefer to just have a gravity flow into the sanitary sewer from my footing perimeter drain and a sump pit for cosmetic purposes.

How do I do this? I assume I'll need some sort of trap on the tile line going into the sanitary sewer, or it will stink. But if I don't have a sump pit, I could just plumb it in and not worry about the stench? This method might also be better regarding back-ups?

I would prefer to have a sump pit so that I can tell someone from the city or a buyer, "Here is my sump pit. It doesn't usually run". Maybe a dummy sump pit is the answer?

In most parts of the civilized world, runnning sump or surface water into a sanitary sewer is illegal. You may be living in an area that is an exception. If it is permitted in your area, a pump with a check valve is the only practical way to do it correctly and protect yourself from the odors/gas and a possible back-up. A back-up can easily plug your drain tile system.

Even in India, they now separate the sewage from a home into sanitary sewage and gray water with separate systems for each. Storm or sump drainage is obviously not permitted in a sanitary line.

Running illegal is the least of my worries, although I would like to have a plan b in case it becomes a problem. In my area, the city has to pump well water into their new turd ponds in order to keep them from drying up. If they dry up, there will be a discharge into the ground as the clay cracks.

So I have no moral pressure to do things right, because right is also wrong. And when it floods, all the turdponds in the state overflow and they eat it in St. Louis.
