Ok, got very brave and lifted the cesspit lid.
Pretty full but mainly liquid I think (and it was emptied not so long since, so should be).
Strongly suspect the soakaway of not working. Went to where the cover is - bad smell there. Couldn't actually see a cover, but found the rocks which the ex put on top to stop idiot townies parking on top of it.
Here is my current theory. For whatever reason the soakaway isn't soaking away.
The drain under the goat byre is probably cut into the pipe/trench that goes from the cesspit to the soakaway.
Since the soakaway isn't soaking away, neither can the rainwater.
The issue now is what to do about it.
I used up all my 'brave' on the opening up the cesspit.
Will have a coffee and a spin, and consider. Might have to call out the drain/cesspit people. God alone knows how I will pay for that but I can't continue like this.
Might go and see if I can find the soakaway cover and lift it, though not sure what I'm going to discover even if I do.
Anyone used these guys? Their website seems to talk sense?
