Outdoor sink grey water drainage

Got the great idea to put a sink outside and would appreciate some direction. I’m torn between tying it into my home’s sewage or just leeching it into the ground. If tying into the existing sewage.. I’m assuming I need to add a vent, will I be happy with one of those under-sink ones? And do I need/want to add clean outs in any point of that? Leeching into the ground seems simple and eco friendly for my trees, but I’m afraid I might be overlooking something. I’m in a desert climate with dry hard clay and plan to leech it away from any structures and nearby some large trees. The setup would have one 5gal bucket filled with rock to act as a grease trap and then continue on to 25-50gal of buried rock to leech into. submitted by /u/Artistic-Jello3986 [link] [comments]
