Food from used water

Abstract

Of course this precious water is not intended for gardening and, in many cases, still has to be carried from the nearest standpipe in plastic containers. Despite this, many households have shown that this newfound source of water can be used for growing vegetables successfully. They save the water that has been used for washing clothes and utensils and feet, so-called grey water, and use it for gardening. One of the most innovative and user-friendly ways of doing this is the “tower garden”. It is not a new idea and South African developments are derived from what was seen in Kenya by a small group of people on a visit to assess treadle pumps. Vegetables are grown in a column of soil that fills a bag.
