The septic tank

They dug the hole at the same time as the wall frames were going up, the plumber did it though not the carpenters!
The hole is 3.3 metres deep, 3 metres square.



The tank itself went in a couple of week later.
It is a Ri- Treat anerobic system, so it's a nice eco friendly alternative which will end up pumping out beautiful clean water onto our garden :)
