How do you know that you’re getting the right advice? EcoSan toilets? Arborloos? DEWATS? UASBs? Even simplified sewerage? Do you, can you, trust the person(s) giving you this advice? Well, there’s nothing like knowledge – at least the knowledge that you should query all advice given to you. If you don’t know all the sanitation alternatives in detail (where they’re appropriate, how to design them, how much they might cost), then you need to find out about them and then query the advice you’ve received – for example you could look at Urban sanitation planning: A technology check list for planners or Sanitation for a healthy nation: Sanitation technology options (DWAF, Government of South Africa, 2002) [there are, of course, other publications but these two are at least both concise and comprehensive].
Let’s make 2012 the Year Of Good Advice!
