@QMS WC waste. But excepting rain water, everything like in the US is drained and vented together. And there's the reason the vents from the sinks, tub, washers, WC etc are all vented together. It's a nightmare finding the source of the gas that makes one woozy.

We have a new pipe out of the Waste Vent Pipe as of today with a restricted air flow cap. We will see if we can encourage air flow towards the secondary vent on the exit side of the Fosse Septique. We should know in a couple of days if we have cleared the interior air.

Who knows if all the joints in the drain pipes are sealed correctly. No leaks are visible, so we are hoping.

Congrats on tracking down the waste water system solutions. I know it is a daunting task.
When we had the foundation excavated for the kitchen addition, the old guy digging found a pipe leading to a "beehive" dry stacked stone pit out front. Turns out the original drain was never hooked up by the former owner's father who had installed it.

It was a terrific find, as I was able to drain the washers and sink gray water into a separate container away from the main septic out back. Of course it had to be all done in a hurry and hush-hush as the DEM permitting process would have upped the cost 10x and taken forever.

But it worked out OK. Had the same old local wizard locate our main septic. He remembered putting it in about 70 years prior. Had some help from the roto-rooter outfit in locating it thru the drain in the basement with fancy electronic probes.

Both drains are working fine now. Separating the black waste from the gray (soapy) waste is key in allowing the microbes to break down solid effluents in the main tank. Can now access both drains thru the ground by building up the tops of the tanks to ground level. Have them pumped every few years. Quite an adventure!

Thanks for the OT!

@enhydra lutris There was a pipe to a deeply buried and therefore anaerobic drainfield. All the gases in the tank had really no place to go except maybe the tank covers.

The septic regulators encourage the use of natural ponds for cleaning the waste or the waste water. Most people don't have the patience for it, but it is catching on.

A huge savings for us as a new aerobic system would have been 17,00-22,000 euros. Ahem. With this compromise, we keep the current septic for first treatment of solids in anaerobic digestion and the fluids into the pond for final digestion. The outflow is clean enough to use as garden water. We hope we can capture it.

People are speculating on a couple of things: where would you put all those submarines?? And how many will be built by 2036?

I was surprised to find out that only the safety portion of the Notre Dame restoration had been completed.

The Datura is some basic one, I should look up. What caught my eye was the resemblance to Brugmansia.

Hope you're having a good time.

saga. It is extremely unlikely in a household situation, but septic foul-ups can also theoretically lead to unsafe methane accumulations. Glad you got it sorted so far and especially that you're planning on moving to a pond system. Best of luck with that.

Not nearly up to speed on my Datura cultivars. Datura wrightii is the "Sacred Datura" of the southwest and Mexico, Datura stramonium is Jimson Weed and all species are poisonous and probably, if properly administered, psychoactive. Best left alone unless you have an experienced traditional shaman handy. I know it has been used for anesthesia, probably long before "western medicine" had "anesthesia".

France's reaction to the US betrayal is almost humorous. Why should they be exempt. The US does not honor agreements, treaties, and contracts except to the extent that they benefit the US. This behavior is older than the formality that is the US, dating back to earliest colonial times.

be well and have a good one
