I'm interested to learn who is doing product and technology design work related to sanitation and if there was interested to start a community of practice related to this work. I know Water For People is doing some interesting work in conjunction with its sani-hubs. I'm also very interested in a mobile septic tank technology so that a service similar to garbage collection could be modeled for FSM services and so that this technology could be used in informal settlements and slum areas where the population might be forced to move. Then they could take their toilet and the emptying service with them. Any ideas here? Thank you.
