So, I have been using RO water for the past 1/2 year or so. but the waste is not really something I like. now for the questions.
1. How much rainwater can I collect per week? the max I need is ~20l per week.
2. how would one go about getting rainwater to collect, off the roof I presume?
3. how pure is rainwater?
4. if collecting water off the roof, How do I know it is safe. (heavy metals and stuff?)
5. how large a water butt do I need?
thanks for reading.
