Wet or Dry Ecological Sanitation - or - To mix or not mix, is that the question?
by Bjorn Brandberg
How much potential has the WC?
A massive stream of food (nutrients) from the rural areas to the cites is impoverishing the soil in the rural areas, and threatening the health of both urban and rural populations. Urban growth has made sullage systems polluting rivers and lakes. Even the oceans are at risk because of the popularity of flush water toilets. An evaluation of alternative sanitation technologies in Luanda low-income areas in Angola caused the author think twice. May be waterborne sanitation using WCs actually is the solution which can save the cities.
