I have a septic tank. I also have 3 water softener units (one is a softner, one is for iron removal and one is for tannin removal). Each runs on a 3 day cycle so one regenerates each night and flushes all the water into the drain. I just discoverd that these don't drain into the septic tank but just into a space in my back yard. I now know the answer to why that area is always soggy. Unfortunately the area has become a mosquito breeding ground and we have a 20 x 20 area of the back yard we really can't use.
I am doing renovations now and have the opportunity to re-route these to feed into my septic tank. My question is whether or not this is a bad thing for the septic tank? It is all water and no solid, but don't know enough about the details of septic to know for sure.
