How clean is your roof, is collection rain water an option there??
As above, the "waste " from the RO need not be wasted, and with a bit of clever plumbing could be used for flushing the toilet, washing cars, watering plants etc etc. How many tanks do you have and how much water (%) are you changing to go thru 750g a week?!
