@samhatchett - Thank you for your advice and yes I should've been clearer, sorry about that.
I'm a final year civil engineering student working on my research dissertation and I wanted to model different non-mechanical water pressure management techniques (e.g. break pressure tanks) for lower income urban areas, so I wanted to find data on water use in said areas (or any urban area in general really).
The PhD dissertation seems promising so far and I'll continue looking at scholarly works as well. Once again thanks for the help.
