Septic back up solution?

[Tspunk]

Hi,

My septic tank sometimes backs up into my basement during heavy rain fall. I'm guessing the field is too saturated. It only happens once in a while, and the amount that gets in is about a full outdoor trash barrel's worth.

My septic line comes out of the basement. I was looking at other people's issues, such as water flowing back up and through a toilet or sink. Well, what if you made a line that went up to a "toilet" but it really routed up and then back outside?

So, off the main line from the basement that goes out to septic, create a line off of that, and then route it to the outside somehow. That way, any back up would come up and out before it could ever reach the 1st floor.

I'm not a plumber, clearly, but it was just a thought. I'm going to ask some plumbers and septic installers in my area to see if that has ever been done.

My thought is, if usually it overflows up a line through the closest/lowest pipe, like a toilet, then why can't we fake that line, but lower, plumbed to the outside? Wouldn't that be the exact same thing, except you don't get gross septic water into your home?

If the proposed outlet would be above ground but still lower than what overflows now, it could work.

These propose the piping for that be outside of the home:

Septic tank safety valve

Hi, I am a landlord with several properties, all on septic tanks. Occasionally, (depending on ground saturation, dirty septic tank filter, dead drain field etc), waste will backup into the house at the lowest fixture (tub or toilet). As a "safety valve", what about putting a "fake" fixture...

Possibly a back water valve (Check)

If it does not leak, and if you are alerted to stop using water when the valve is closed. Flapper type sewage check valves will leak with time, and "normally open" check valves are much better in that regard.

In civilized plumbing codes the back water valve (check) is designed to have the flapper partially open to allow for circulation of air to prevent pockets of sewer fumes.

They also have to be accessible for service as required by modern plumbing codes.
