- jillesvangurp 5y agoI think the difference here is that the materials used are cheap and easy to procure. That sounds like maintenance should be straightforward. The difference between producing water locally and shipping/trucking it in is probably huge in places without water pipes. A couple of gallons a day goes a long way. Scale it up a little and now you are irrigating your vegetable garden as well.
- ghshephard 5y agoThe Reverse osmosis cost estimate was based on a 10 year committed Hyflux Desalination commercial contract with the PUB in Singapore (from about 5 years ago, so might be less expensive now, actaully) - so includes maintenance costs. Regardless - this isn't a scale able solution, but doesn't need to be - should work fantastic for a small family with negligible environmental impact.
