I live in Michigan near a lake. Have been hear for 4 yearsl, last 2 1/2 years doing laundry which dumps into the septic no problems. Had slow flushing and gurgling of pipes had system pumped(septic tank only, thought i had a drain field). 25 days later filled again i called different pumper he took a rod and jammed it into the ground and said "you have a drywell" we dug up the opening and it was full. This time i pumped both. Looking in the drywell i could see on the side what appeared to be quite a few roots. When i went out into the yard where i thought the drain field was i withched in what appears to be four distinct lines spaced exactly 4 feet apart and about 40 feel long. Is it possilbe they would have run a drain field off the drywell? Is there any way that i can get this drywell cleaned out(roots especially)?
