To be honest I just don't have enough information for any kind of educated speculation. Most of the cost/benefit figures I saw compared the cost of building such an installation vs. importing water over long distances with pipes (or even trucks), but paid little heed to operational costs. I don't know if/ how often they must replace their filters. They clean the pipes frequently. With the sewage water reclamation, you still need to do something with the "solids" and other impurities they they filter out, so perhaps that could drive these costs higher? With reverse osmosis, I'm not sure if you can sell the leftover salt, or if it's disposed of. I wish I could help some more. Perhaps I'll start doing some research, but for now that's all I have! Do you have any other insights? Andrew:

I like in Windhoek in Namibia which a few years ago installed a system for rapidly recycling most of its sewage into its water supply (the alternative was to flood yet more valleys in a very unreliable climate). The country generally is facing an acute water shortage particularly now the uranium companies are moving in in a big way and sucking out the remaining ground water. What interests me is how the recurrent cost of quick recycling like this compares (per cubic metre) with reverse osmosis extraction from seawater. I have the impression that the two are not incomparable. Any ideas? I’ve come across this article rather late – apologies.

I've read just a little about wetlands and their natural abilities to purify water. I think there might even be a house that purifies and recycles all of its own water through the garden/wetland in the back yard... clearly more investigation is needed. But with water becoming an ever-more-urgent issue around the globe, I really think technologies like this one can go a long way towards relieving demand and our draw from natural sources. Absolutely!

It really is an area of science that we need to continue to make more efficient. Kind of reminds me of the movie dune where the one group wore suites which reclaimed the bodies water.
