We are on well water. I am contemplating installing a 450 GPD RO system to produce sufficient water for drinking and for gardening. Actual usage would likely be around 100 GPD. Our well has never ran dry, but some neighbors have problems. Thus, I'm pretty cautious about how we use our water. RO systems are known to be fairly wasteful. I was wondering about running the RO waste water back to the well. I know it would drive the salinity of the water up going to the house, but I'm guessing it wouldn't go up too much given the consumption of water by a family of 4. Is this a good or bad idea and why?
