While I was reading the article I wondered what will be done once the water will have withdrawn from the land. Which solutions to provide safe drinking water will be used, are there any efforts to support and promote sustainable, decentralized solutions that can help the people immediatly? As there is no centralized waste water treating system the city needs decentralized solutions to provide its people with freshwater. Has anyone ever tried DEWATS in this region. It is a proven solution which has been provided in country like India, Indonesia and east plus southern Africa. Unfortunately it might not have disseminated to western Africa. If somebody reads this and is interested in an relatively low cost, sustainable and easy to maintain solution to treat wastewater in small and medium scale please search for BORDA. I have heard of this organization a couple of weeks ago and they are doing great work in asia and southern africa. www.borda-net.org.
