JOUKASOU

In 2016-2018, CTI, in cooperation with professional and government actors from Japan (Institute for Global Environmental Strategies, IGES),  implemented a JOKASOU demonstration project (KÉK TANYA) in Central-Hungary.

JOUKASOU  (浄化槽), a term in Japanese, is an advanced version of the facility for individual treatment of household wastewater (septic tank). In a broader sense, it stands for the national system of decentralized treatment of household wastewater in Japan, serving over 30 million people in the countriside. Also,  JOUKASOU comprehensively means small wastewater treatment technologies.

JOUKASOU, in Japan, is regulated and governed by the government, supported with professional, industry and municipal actors. The government of Japan promotes the JOUKASOU technology transfer, in particular, in the Far-East, most recently though even to advanced economies, in Europe, too.

The Japan Education Center for Environmental Sanitation, a foundation of the Ministry of Health, Labor and Welfare, has been an educational and research institution for over six decades for training technicians of installation, maintenance and desludging of JOUKASOU, as well as for developing JOUKASOU technologies.
