Tank for Purifying
Johkasou is a sophisticated treatment system that uses
anaerobic, aerobic and disinfectant processes to render
blackwater (that bears human excreta) and/or greywater
(from kitchens and sinks) relatively harmless and clean.
Johkasou system was introduced in Japan in 1911 and
developed rapidly in 1960s to meet the high demand for
clean water.
Difference between Septic Tank and Johkasou
In many countries, septic tanks as anaerobic
digesters are still built for domestic wastewater
treatment. Johkasou uses Japanese original
method, which combines aerobic, anaerobic,
filtration, and disinfection treatments while both
anaerobic and aerobic bacteria are cultivated
naturally in Johkasou Ecosystem
Water Re-Use
Treated Effluent from Kubota

local regulations.
