Thanks for sharing!!
I just read your document, and find it very good.
I was only wondering, in the 1st activity:
Local policies that encourage the use of clean technologies for waste water disposal
Are these technologies called "clean technologies" beacause they have a low carbon footprint? Where do their energy comes from?
Which "clean technology" did you find to be the mos suitable ? (if the article, wich I haven't read, provides with specific examples)
