Oh Yes! an Update...
Two weeks ago Doug Zacharias of Doug Zacharias Trucking Ltd installed the septic system. No pictures of the work except for the entry though the wall, but I will discuss the system that was installed in future posts.
Here you can see the 4-inch pipe leading to the septic tank coming through the concrete wall. It is sealed into the wall using a bit of spray foam.
As you know the expression is "Sh#t flows down hit", hence this pipe is not level but slopes down at a rate of 1/4 inch per foot.
