soakaway

The liquid effluent flowing out of the tank is, from a health point of view, as dangerous as raw sewage and remains to be disposed of, normally by soaking into the ground through a soakaway or with a connection to small-bore sewers.

- Dispersal systems using simple or multiple trenches are an alternative to soakaway pits for less permeable soils, where there are large quantities of effluent, in the case of a high water table or where there are rocky layers near the surface.

Chapter 3 1994

- The bottom of the soakaway pit should be at least 1m above the water table during the wettest period, and 1m above any impermeable layers.

Chapter 3 1994

Fill the soakaway pit with stones up to the level of the trench bottom.

Chapter 3 1994

Determine the dimensions of the soakaway pit according to the quantity of wastewater to be infiltrated and the permeability of the soil.
