Step 4: Discharge

After 24hrs, 99+% of the waste has been broken down by the micro-organisms. The polluting strength of the wastewater will have been reduced by 50-60 times, the total solids that remain in suspension will have been reduced by 99+%, and the resulting effluent is cleaner than the initial discharge from many municipal treatment plants. This clear, odor-free liquid will then flow into the drain field to be naturally dispersed into the ground.
