For this report you are to draw a process diagram showing the trail of water from rain cloud back to rain cloud via the built environment.
Your process drawing may fit on a single sheet of A3 but it may not. It will be neat, elegantly formed and skilfully considered and as such will be informative, attractive and a thing of beauty in itself.
Your report submission can be hand drawn, computer drawn, coloured or not but must be fully annotated. It must be highly analytical of issues like water usage, water treatment, rainfall, population growth, water-saving measures, water collection, grey water etc etc. You will need to make your own investigations, undertake your own reading and present your work in your own words and using your own drawings.
