Recycling used WATER?

I don't know why, but I've heard that in many places a gray water tank is not legal. Now WHY would that be? Are they afraid that it might get mixed in with the township's treated water supply? I suppose thats a legitimate concern. Even so, I'm planning on having one. I plan on routing all the shower, bathroom sink, and washer water to the graywater tank. That way it shouldn't get mixed in with anything else.

But what can I do right NOW? I don't have the know how to make a gray water tank just yet. And I'm pretty busy with the many other eco projects I'm already doing. So, for the time being, I brush my teeth and use a drinking cup to wet my brush, and rinse my mouth. That cuts down on the inital amount of water.

I wash my face over a bucket. I fill a bucket with some water to shave my legs with. (This is also enough to warm my feet in winter without wasting 50gal of water in the tub!). I do laundry in buckets right now, but I *will* be using the Wonder Clean and draining the used water into a bucket.

Then I carry the bucket to plants that need watering.

Of course, then I have to be careful what kinds of soap I use. Not all soaps are good for plants. So, I use castille or glycerin soaps. No strange sounding, unpronounceable chemical names.

This way much less water is used initially, and all the water gets used twice.
