Gray Water Recycling at Home

Image:EnviroSink cutaway 101a.gif
Homes and even towns should be fitted with two drainage systems in the plumbing: one for the sewer, and one for gray water. The gray water, such as from showers and washing machines, could then be collected and treated if necessary, then used for use in gardening or lawns and other landscape watering needs.

There are various health and environmental risks if you do not use gray water safely. Choose phosphate-free or low-phosphate household cleaners and detergents.

Another plumbing modification that would require a simple holding tank, would be to use safe gray water to flush toilets, rather than culinary water.

In homes already built without such a system, alternate means, though not as efficient, can be employed to collect the gray water for these uses.
