ETA BEDS
Evaporation -Transpiration -Absorption Beds, with this system the effluent is piped through disposal pipes into specially constructed beds or trenches, incorporating plants.
These plants absorb a proportion of the effluent through their root system and release it into the atmosphere through their leaves during the natural process of Transpiration.
The ground absorbs some of the effluent, sun and wind also assist In the process as the effluent is drawn to the surface by capillary action and then evaporates.
A most important factor for sizing of the Beds is the Daily Loading Rate (DLR) and the limitations of the soil. This system is mostly maintenance free and considered the safest way of disposing of effluent, as it guarantees complete separation of human and animal from all wastewater, regardless of whether it has been disinfected.
Owners of ETA Beds should establish appropriate vegetation, in addition to grassing the Beds, shrubs can be planted around the Beds (not on), a list of suitable shrubs listed below.
