Some good news. I was very nervous, particularly after having dug out by hand tonnes of saturated clay in order to find and uncover the fosse septique. My French neighbour was very happy to take a hammer and chisel to the whole affair on the understanding that Vidage Blancoise who were coming on Monday or Tuesday ( tomorrow or the day after) would expect the fosse to be ready for emptying. . However, just as we were off to Chateauroux on Saturday (yesterday) afternnoon, a tanker arrived. The driver was only too happy to apply his hammer and chisel and lo and behold he uncovered beneath lumps of mortar a nicely fitting circular hatch. Maybe I was just lucky, another driver and who knows. Having inspected the contents of my fosse I would advise anyone who doesn't know the history of their installation, to get it emptied straight away, no matter how many packets of whatever you have flushed down the loo.Every four years I shall very happly pay out 170euros, although I must work out how to reduce the digging invoved. Take care
