Many Thanks for your help Jonathan Parkinson. It has helped me a lot the information given. I am analyzing in detail the "Wastewater Risk Abatement and Stabilization Plan (WRASP)" you mentioned and is quite interesting. If you know other organizations, associations (as IWA) or some other country where they are implementing consolidation plans, I would greatly appreciate

Dear Felipe, it is an interesting question. I think WHO have initiated a procedure for testing and certification of household water treatment technologies but I don't think anything exists that relates for sanitation facilities. IWA has had some discussion with WHO about formulating a normative framework for sanitation systems that presumably would serve the purpose that you are asking about. As I understand it, the Sanitation Safety Planning process (currently being developed) would the be the process by which a sanitation system would be assessed in relation to these norms. But it is still early days and therefore I think currently the answer is negative. There may be some attempts at a national level - the closest I can think of is the Wastewater Risk Abatement and Stabilization Plan (WRASP) which has been applied in South Africa and Kenya (and maybe other places) but this is for downstream wastewater treatment facilities not household sanitation, and I don't think is quite what you are looking for. I'd therefore also be interested to hear from anyone who knows of any relevant framework and experiences in applying this framework relevant to Felipe's question.best regards, Jonathan Parkinson (IWA)

Dear

I introduce myself, my name is Felipe Figueroa and I am a student at the Technical University Federico Santa Maria (UTFSM) Valparaiso city, Chile. Right now I am working to the chilean company "Innsania SpA", in their social product named "BIS" (www.bischile.org), a bathroom module that provides health, dignity and self-sufficiency through the reuse of water and waste.
I wonder if they know international standards (international sanitation policies) to carry out the certification of this product because, here in Chile there are no regulations to endorse this kind of sanitation systems

Without further ado and waiting for a prompt reply from you,
best regards
