What is a Johkasou?

“Johkasou” literally means “purification tank onsite wastewater treatment system” in Japanese.
In Japan, where people can’t connect to a centralized public sewage plant, all household wastewater goes directly into a Johkasou, which is usually installed underground as a single compact tank. There are five functional chambers (sedimentation, anaerobic, aeration, storage and disinfection) in a tank. Johkasou technology is now greatly improved with treatment performance equivalent to that of a centralized public sewage plant.

Why should I choose Johkasou Septic Tanks?

The Johkasou system , which has been developed and manufactured in Japan, is one of the best solutions of wastewater treatment in areas where sewage infrastructure has not yet been improved worldwide.

Various types and sizes are available from small residential units to large commercial units.

The Johkasou system was built to be compact and to reduce environmental pollution, making the system have the following key features and advantages.
