I have an anerobic system. They have three tanks, all waste goes into the first with a agitator that breaks it down The second tank is for the solids to settle out. The liquid goes into the last tank, gets clorine added. Gets sprayed onto the yard. Mine stinks too, clorine and other chemicals have to be added periodically. I have to call my contractor (got a service contract) to come add the chemicals to make it not stink.
