The fun of self build. I've spent most of the day working out how to design a sewage treatment plant and drainage field where the water table almost reaches the surface in winter.
I'm now looking at a holding tank and pump to squirt the outgoing liquid from the treatment plant into a "drainage mound". As the saying goes ... its a load of sh1t.
My next task this weekend is to do a "percolation test" so I know how big to make everything.
One of the issues is it looks like I have to anchor the tanks in the ground to stop them floating out of the ground when the groundwater levels are high. Basically I have to bolt them down to a concrete slab.
