Sample Treatment Methods for Indoor Use of Rainwater
Specific filtration and disinfection requirements are determined by local regulations and installer preferences, but here are some common treatment methods for different end uses:
Toilet
▪ Filtration: Minimum 50-micron sediment filter (prevents grit from interfering with toilet valves)
▪ Optional: Carbon filter to address any color or odor issues
▪ Permitting agencies may require 5-micron filters and disinfection

My opinions are barely worth the paper they are written on here, but hopefully they can spark some new ideas, or at least a different train of thought

Rain water is an excellent resource for watering your garden, unless you can collect so much that you can't use it all on the garden, why waste it anywhere else? The same goes for grey water.
Until you get to the point where you have an abundance of rain/grey water and can't use it all in the garden, it's pointless to try using it anywhere else. Think about it, if you want to use it in the toilet you are going to have to build filters etc. which will require time and materials (money) then you will have ongoing maintenance of those filters (more time and resources), plus you will have to add new plumbing, seperate from your existing plumbing, to route this water to your toilets. Either that or fill your toilets from buckets (more time and resources). After you go through all of that, what do you gain?
