Was chatting with the gardener - at some point I probably want to lay some pipe through the garden to take the water from the cellar pump to the fosse at the edge of our plot (which will need a trench hence asking the gardener - but he seems a practical type and, of course, he knows someone with a backhoe )
So, I was trying to describe the situation - pompe de vidange is easy enough but I was stupmed for the best word for “sump” - puisard? but Word Reference suggests that is in the context of a cesspool which definitely isn’t what I have going on in the cellar.
Is there a better word?
