Yes more pics please... would also like a diagram of the system from water collection to your main pure water storage(somehow my brain doesnt always compute a pic, but a drawing is easier for me)
Ref grants, I may be wide of the mark but the basic concept is that any outlay for the equipment is 100% tax deductible as you are improving your green credentials(might also be a good selling point to customers)
There are a few links via goole to this but i'm damned if I can find them at the mo!!Will post up when I do
