My brother thought he would save a few bob and install he's own septic tank. All was going well until 4.30 on Sunday afternoon. As he tipped the last load of pea shingle into the hole with the new tank in, the sides gave way and the dumper also went in He was not hurt but the new tank got smashed and he had to dig it out start all over again. Lucky a local farmer has a JCB to get it out otherwise it would still be there now
