Thanks for the ideas Tweva and 74 will try that out!
How did your wife do at the range 74?
We have some more grading of the land going on today and the pipes for the septic tank are put into the ground. We opted for an oversized septic tank to make sure the blackwater stays in there long enough (1500L for 2 people).
