Any of my Illinois inspectors know if it is illegal to dump greywater on the exterior grounds? The house is in a rural area and the homeowner is discharging the washing machine to a ditch in front of the home rather than tying into the septic system. I checked the IDPH and did not get a clear answer, I have also spoke with plumbers and septic professionals and their answers are all over the board. I have ran into this in the past in the city and called it out because of the greaywater mixing with the surface water that will most likely be collected and treated. Another concern is when disposing in this manner is there a proper variance between the well and the greywater which could contaminate the potable water. Thank you in advance for your comments.
