The dedicated catchment system sounds logical. I would say though that at that level of complexity RO filtration to remove chemicals would become competitive.
One issue I have with RO is that it sends 75% of the water to the drain while it gives you the remaining 25% as clean drinking water. This is wasteful of both water and energy. As I type I am wondering whether you can send the 75% back to the catchment tank. As for the energy it may be another example of the money to fix the problem being best spent on another solar panel. Or another blue cube. Any time you handle the water there is a risk of contamination though.
