Single ventilated improved pit

The Single VIP is a Ventilated, Improved Pit. It is an improvement over the Single Pit because continuous airflow through the ventilation pipe vents odours and acts as a trap for flies as they escape towards the light. Despite their simplicity, well-designed Single VIPs can be completely smell free, and be more pleasant to use than some other water-based technologies.
