Even though the treated water from the BioPod exceeds Australian Standards, it is safest to keep it in the soil. The soil is an effective barrier to human contact with effluent. It eliminates the hygiene risks associated with exposure to spray drift potentially containing pathogens.
As the risk from above-ground sprinklers is comparatively high, it requires disinfection to be used. If the disinfection system fails, or if the often short service intervals are not observed, the environmental and hygiene risks can be high.
It's bought peace of mind knowing we're not putting polluted run off into the surrounding bush, and knowing our kids aren't playing in dangerous sewage runoff is immensely reassuring.
