Did you know that greywater comprises 50-80% of residential wastewater. I would guess that half or more of my water usage in for bathing alone. In terms of gallons, that is at least 2000 gallons.

What is greywater anyway? Greywater is wastewater generated from processes such as dish washing, laundry and bathing. From what I have been read the kitchen sink and dishwasher should be left out of a greywater system because food waste is not something one really wants to get involved with. Trust me, if you were to install a greywater system you will have more then enough water from the other great produces of greywater. (Wash basins, showers and bathtubs, cloths washer)

Lets think more about what greywater is. It is mostly going to be water with small amounts soap and dirt. It will not have food waste (not mine idea of greywater anyway) or any human waste. That would be called blackwater. Anyone that is familiar with RVs knows about blackwater and greywater holding tanks.

The best time to implement a greywater system is during construction. So for me, this is one of those dream house concepts. The only extra costs is installing separate drains for the toilets and kitchen. These flow right into a septic or sewer system. The other drains go into a holding tank to be used for toilet flushing or irrigation. (For toilets, you would have to line a greywater line to that commode.) You would also need a small pump so that you could have water pressure.

Greywater is safe if used correctly. For many homes this could save large amounts of water. For homes with irrigation systems, this would be a great solution to high water bills. If you are on a well, your well pump would run much less. Saving you money in electricity costs. I believe that most new homes should include a greywater system. It just make sense.
