I was brought along as digger driver to fit a Klargester (septic tank) at a farm. Hole dug, tank fitted with inlet pipes to falls etc. Builder in charge then backfilled with pea gravel but not concrete, which is recommended when the water table is visible. And it was visible.
When we got back to the job in the morning, instead of the pipes running downhill to the tank, they were now running uphill! Start again boys. Luckily we had a huge machine and large amounts of pea gravel at hand. Needless to say, the tank was concreted in.
