Thimphu is witnessing the implementation of Japanese technology-   Johkasou wastewater treatment- to treat wastewater in the Bhutanese city.

The new technology can address wastewater issues with its ability to treat wastewater at the household level. The project implemented by the Bhutan Toilet Organisation in collaboration with the Thimphu Thromde aims to tackle wastewater issues in the country, reports The Bhutan Live.

The pilot project installed the first Johkasou wastewater treatment tanks in two households in upper Motithang, the news portal reported.

The installation process took two days for completion.

The pilot initiative started when JOYLET Japan introduced the tanks and by sponsoring of six tanks, along with technical support for installation and maintenance.

According to the Bhutan Toilet Organisation, the Johkasou wastewater tanks will serve as an option for households whose wastewater overflows into nearby streams, which will help reduce wastewater-related environmental pollution, the news portal reported.

“These Johkasou tanks can treat the wastewater itself, which is similar to the septic tank. We keep our septic tanks underground, however, in Japan, the wastewater in the septic tanks gets treated and comes out as clean water. So, we are working on this pilot project to see the results of the technology in our country,” Chablop Passang Tshering, Executive Director, told Bhutan Live.

He added that the resulting treated water from the Johkasou tanks is suitable for washing clothes and gardening purposes.

“Since it is a Japanese technology, we are facing issues with the workmanship while installing. And we are worried that the people might dump even solid waste, which will damage the tank.”
