Greywater

Catalog description

One lecture. Don’t let good “greywater” from tubs, sinks and washers do down the drain! Greywater re-use for landscape irrigation is safe and legal when done properly. In this class we’ll explore greywater options, some simple, some more complex, including systems that when combined with use of composting toilets constitute affordable alternatives for people with difficult “perc” conditions. Students will be able to: understand Arizona’s legal definition of Greywater; understand Greywater in relation to shifting energy and economic conditions; understand Greywater as part of total water-wise living; define when kitchen water is also Greywater; distinguish Graywater from Blackwater. Grading Option: May be taken for S/U credit.
