When should a lined Evapotranspiration field be used?

A lined Evapotranspiration field is most appropriately used when groundwater is shallow and soil is thin. This design helps to prevent contaminants from reaching the groundwater, which is crucial in maintaining water quality and protecting public health in areas where the soil is insufficient to provide adequate treatment. In situations where the soil is thin, native soil may not provide the necessary filtration and absorption required for effective wastewater treatment. Hence, lining the field creates a barrier that mitigates the risk of effluent leaching into groundwater, while allowing for the evaporation and transpiration processes to assist in the treatment and disposal of sewage.

Utilizing a lined field in these conditions helps to manage wastewater safely and ensures compliance with environmental regulations.
