What is Greywater? Lightly used water from showers/baths, lavatory sinks and washing machines.
Greywater is a resource. Greywater can be reused on-site for garden and lawn irrigation (see Laundry to Landscape & Simple Greywater Systems). Untreated Greywater contains nutrients, such as nitrogen and phosphorus which benefit plant growth. Treated greywater (See AQUALOOP) can be used for toilet flushing and laundry use (cold-water washing machine only).
When we make the choice to substitute the use of drinking water for irrigation, it will not only reduce the demand on drinking water supplies, but also reduce the amount of wastewater discharged to the environment.
