Thus for or example we have designed a duel handle water closet (toilet) one handle for liquid waste and the other handle that allow more water through for the flushing mechanism to allow for the removal of solids. See www.caroma.com.au The worlds first 6 or 3 litre flushing system.

The use of "gray" water is not new as many places use gray water not only for irrigation of farm crops / lawns BUT also for fire protection systems.

If recycling was fully utilized we would have an abundance of natural "gas."

Just the sewerage alone in NYC could generate enough methane gases to gas for supply millions of homes with clean burning fuel used for cooking and heating.

In the very large office buildings it should be mandatory to install a water treatment program "IN HOUSE" and if properly performed a large building could re use over 90% of the waste water. For example if basin and drinking water fountains emptied into the same drain line with storm water in a large holding tank this water is not that difficult to treat for reuse in either lawn sprinkler / fire protection and street cleaning and if properly filtered it could even be recirculated back into the potable water system with less cost to the building owners and municipalities for dams drilling / pumping or treatment plants.

The soil lines (sewerage) can be either drawn off to use as a fertilizer or converted to methane fuel to operate the air conditioning systems and thus lowering the over all cost to the buildings use in natural gas as this could be a supplement.

Some 3rd world countries use human and animal waste for helping crops grow.

Water is very recyclable. As "new water " is not created we have actually been using the same water over and over for the last million or so years.

The problems today is finding clean water as with urbanisation and industry came pollution.

Thankfully we have the means and the knowledge to recycle the poorest of water quality with various systems. It just has to do with how badly we want to conserve and what sacrifices we are willing to do for the limited amount CLEAN water availible to us on this planet.

When I was 17 in the Navy the ships I served on never carried portable water they purified sea water as needed and used the "raw" sea water strictly for washing the decks and fire protection. depending on the size of the crew population determained how big these purifiers were.

The same with either office buildings or for that matter housing developments sharing a common purification system.

Think about this, the astronauts that were sent into outer space did not have the luxury of carrying unlimited amounts of water. Rather then go into details I'LL let you guess where their water came from that was water they used "recycled"
