Greywater Systems

Water from the shower, the sink and the washing machine is barely dirty and, on a property with a garden, it is the difference between irrigating in August and not. Keeping it separate from the toilet is the whole trick.

Várzea da Gonçala runs greywater into planted beds on a permaculture smallholding near Aljezur. Folha Verde does the same at community scale in the Serra do Açor. Salema Eco Camp built it into a coastal campsite, Ecodepur and Environmental Waves supply the engineered versions, and Oásis Biosistema designs the planted ones.

Soap choice matters more than people expect: what goes down the drain goes onto the garden. See also natural water purification, compost toilets and water conservation. Dated activities from these projects are listed in our events calendar.
