The inspector was a bit leery about the depth of my tank ( about 2 foot below the surface - made necessary by the slope ) but the drainage network is only about 20-30cm below the surface and that was as designed. It might be worth tracing where the drains go to avoid future grief.


Drains ? You jest !

Tank was installed before my purchase of the property. Apparently, even then, it broke stone slabs covering the millrace, and my vendors never told me either the capacity or the exact location (there were no vents giving it away). Doing some gardening work, putting down a 40cm layer of good soil, the tractor moving the soil fell through the top cover of the plastic fosse. It is completely beyond repair.

We don't have mains drains & here is a bit "particulier" (as are lots of places in France) inasmuch that we have a watermill perched on a slope, surrounded on 3 sides by watercourses. Available land for a tank & filtered drainage just doesn't exist; for a tank properly treating brown water, it's OK; epandage means it would disperse to natural watercourses.

Which is why I want to put in a new installation which might (or not) conform, but using new technologies and "normes".

Any other ideas ?
