Hello,
It is generally accepted that grey water must be used within 24 hours of catchment due to the buildup of bacteria. So, in theory, this timeframe could be extended if the grey water was diluted with fresh water until use. The question is at what ratio and for how long? Has anyone ever considered this approach? I can find no mention of this in my research.
I have an idea that could automatically add harvested rainwater to my grey water at a 1:1 or whatever ration. The goal would be to extend storage time to about three days for my particular irrigation schedule, not to mention ease the concentration of particulates that the filters would have to deal with at one time.
Peace,
Dr. Z.
