Miles of pipe under most cities. Don't forget storm water. I still don't
get why we build houses now with a roof then effectively install another

I guess the problem is there must be a dollar in it.  

The above mentioned product (I am unable to follow the link at the moment
thank you Telstra) I assume is designed to be replaceable over serviceable.
I am also guessing at the mentioned  price they plan to flood the market.
