Why does it matter? - Energy usage: We need to use less energy with efficient washers and cold water (unless there is abundant solar hot water), and use renewable energy where possible.
Water usage: The more water we use, the harder it is to process the waste water, and the more strain we place on the water supply.
Water pollution: Minimize the use of detergent. Consider these words about the chemicals you use. Once people appreciate that they make other things dirty when they make their clothes clean, they think differently about what they're doing.

The water leaving our homes carries nutrients and value. It may also contain pathogens, and/or harsh chemicals and care should be taken with it. However, it is not a great risk compared to blackwater (sewage). Redirecting the water we use for tasks such as showering allows us to reclaim some of that value to grow plants and recharge the water table. It may be necessary to choose our soaps and detergents more carefully, if we use the greywater for watering and fertilizing plants. |
