So far my only utilities coming into the house are water, electricity and phone. I have a septic tank which means I don't pay for sewage and the septic tank works pretty well if you look after it and keep feeding in the bacteria additives it could last many years. Besides I need to upgrade it next year, but that's already on the cards to be done.
To be honest when I wanted to know about this kind of thing (in particular food storage and water) I PM'd Red. The fact Red is not cleaning himself with baby wipes and just chucked 6000 litres of water shows that to have been a good choice.
