Whenever a Full Access or Compact toilet is used for defecation a small amount of “soak” material, usually wood-shavings, is added to the vault. Alternatively a suitable amount can be added at the end of the day by a manager. The purpose of soak is to
- [i] maintain an open structure so as to prevent the pile becoming anaerobic,
- [ii] soak up excess moisture,
- [iii] adjust the carbon-nitrogen ratio by adding more carbon,
- [iv] cover the wastes. We will advise on a suitable soak material for the type of toilet you decide to purchase.
The Zero Discharge toilet does not require additions of soak.
