Grey Water and Rain

This is one of those things that seems so simple and obvious and yet, apparently is the *new* and *experimental* thing to charge big bucks for.  I'm assuming that by the time Ba'al and I are ready to build, the costs will have come down a great deal.

A grey water system is a water reuse system.  Water from showers, sinks, and washing machines drains into a cistern.  The cistern then feeds through a filter and into the toilet.  Once it goes through the toilet, the water then goes into the septic system.  We want to add an extra step by putting the grey water first through a radiant floor system, and then into the toilet.  

Grey water systems save a household 30% on their water bill on average.

We also intend to install a rainwater cistern.  Basically, we'll put barrels under the downspouts and this water will be used to help irrigate the garden.  That alone should save us a great deal of money and be far kinder to the local environment by reducing our reliance on a drilled well.
