Japan-based water-treatment company Daiki Axis plans to invest approximately ₹200 cr to establish its third manufacturing facility in India, with the new plant proposed for Tumakuru, Karnataka.

The facility will be set up by Daiki Axis India, the company’s wholly owned Indian subsidiary, and will manufacture and assemble decentralised sewage-treatment systems based on Johkasou technology.

Johkasou is a Japanese decentralised wastewater-treatment system that treats sewage close to the point where it is generated. This approach can reduce dependence on extensive sewer networks and support the reuse of treated wastewater for applications such as landscaping, gardening and other non-potable purposes.

Daiki Axis India Advisor K C Pandey said the company’s expansion comes as urbanisation, industrial growth and pressure on water resources increase demand for wastewater-treatment and recycling technologies in India.

The proposed plant is expected to strengthen local manufacturing, reduce dependence on imports and support faster deployment of decentralised treatment systems across the country.

Pandey said India has significant potential for treated wastewater reuse. The country has more than 24,000 urban parks, as well as residential complexes, institutions, hotels and industrial facilities that could use treated water for landscaping, gardening and other non-potable purposes.

The expansion is aligned with the government’s Make in India initiative and the broader Viksit Bharat 2047 vision, according to Pandey. He said the growing focus on circular water use, treated wastewater reuse, smart cities and sustainable urban development would create long-term demand for decentralised sewage-treatment systems.

Daiki Axis currently operates two manufacturing facilities in India, located at Baroda in Gujarat and Palwal near Faridabad in Haryana.

Pandey said India generates more than 72 billion litres of sewage every day, while wastewater-treatment capacity remains inadequate in several regions. As a result, untreated sewage continues to enter rivers and other water bodies.

The company’s expansion comes as India seeks to increase wastewater treatment, improve sanitation and reduce pressure on freshwater resources. The effectiveness of decentralised systems will depend on factors including treatment performance, maintenance, power requirements, sludge management, monitoring and the quality of treated water produced.
