What are these "sewers" of which you speak?
Wombat towers (all of one storey high) doesn't have any truck with any of that nonsense, being equipped with a septic tank, allegedly a soakaway, in clayish muck, and doesn't even have a mains water supply. Nearly all my electricity comes from the sky, but there is a mains connection. We have got fibre broadband to the house, though!
I hasten to add we do have piped water, it comes from our private borehole (150ft deep), and is absolutely lovely! Beautiful clear, softish, water with no muck added to it.
