Septic tank (bio-septic)
Multi-chamber sewage treatment using bacteria—cleaner effluent than basic tanks, important for groundwater in dense green areas.
A bio-septic system uses multiple chambers and natural bacteria to treat sewage more thoroughly than a basic single-chamber tank. Effluent is typically cleaner and safer for surrounding groundwater.
In Ubud’s nature-focused neighbourhoods, responsible wastewater handling is both an environmental and a neighbour-relations issue. Ask where effluent fields discharge, how often tanks are serviced, and whether the design matches guest capacity.
