Air, vigor- ously stirred or bubbled into the , nourishes aerobic bacteria, which brciik down the complex or- ganic compounds of the wastes into simpler inoffensive ones Tile products of their labor are a reasonably clear liquid and sludge The liquid is discharged to a leaching bed. Tile sludge, like sludge from a septic tank, must be pumped out periodically by a licensed contractor and disposed of in a manner approxed by your local health unit or ministry- district office. Although these aerobic units are more expensive than septic tanks, they give a purer effluent. For this reason, in comparison with a septic tank system, less distribution pipe is required in an absorption trench leaching bed, and in a filter-type bed, a smaller area is permitted. This often means, for example, that trees which would have to be cleared for a septic tank system may be saved if an aerobic system is used. Before purchasing an aerobic sys- tem, be sure that it is accepted by the Ministry of the Environment. Check with your local health unit or ministr)' district office.
