Gray Water for Green Solutions

this problem/solution/opportunity of gray water, along with diverted rain water is well known and developed with patented systems in Australia and areas in South America and the 'reserving of water' has been in place for many years to accomplish the tasks mentioned as well as being a ready supply for fire suppression etc.

a study of 'what has come before' would be in order whether used in a residential or commercial setting -

I would be like to be part of a larger discussion / consideration of this topic as the opportunities are truly global in nature and ramification -

Instead of using a diverter valve a simpler approach would be to simply plumb all of the black water sources (toilet, garbage disposer, dish washer, etc) directly into the septic tank or sewer. Then plumb all of the gray water sources into the gray water sistern.

Without purification I would imagine the uses of the gray water would be limited to lawn irrigation. The gray water tanks on the yachts we build get VERY VERY stinky and foul... not something I would want to bathe in a second time.

Also, the gray water will have a ton of hair from the bath and shower. Given that strainers would have to be employed to protect the pumps and also to your lawn from having hair on it.

I think that using a diverter valve would be prone to failure - mechanical but mostly human.

If you have a big tank you can collect and store rainwater, it requires far less treatment, and is already clean. You can use it to flush toilets without treatment, maybe a filter and you can wash clothes using less detergent because it is soft, more treatment and you can drink it. If you want to treat greywater because you enjoy engineering do so, and return it to the system / ground at less than drinking quality, but rainwater harvesting is so simple everyone overlooks it. the key is storage capacity, to get you over the dry spells.

Brac Greywater Recycling Systems

The Brac Greywater Recyling System is available in the Atlanta region from Southern Energy Solutions, Marietta, Georgia, United States. http://www.soenso.com

The Brac Greywater Recycling System takes in greywater (bath/shower/laundry water), filters and treats it, then sends it on demand for toilet flushing. By reusing greywater for toilet flushing, the typical home can save 30% or more on potable water consumption.

The Brac Systems are available in residential-use sizes 250/350/450 liters (66/92/119 gallons US) and commercial-use sizes 4200/5000/6600 liters (1110/1320/1745 gallons US).
