Japanese environmental-technology company Hiyoshi is looking to extend its wastewater and air-monitoring work to India, according to a report published on 21 October 2026. The company’s experience includes maintaining wastewater treatment systems and helping recover Lake Biwa from red-tide damage, although the report did not identify a specific Indian project, investment or procurement package.

- Hiyoshi says it wants to transfer environmental-protection technology to India as the country seeks greater capacity in water and sewage systems. ANI News
- The company says its work has expanded from wastewater-treatment service and management into water and sewage analysis, followed by air-condition analysis. ANI News
- Hiyoshi reports that 1,110 overseas researchers from 53 countries have visited to study its advanced technology. ANI News

Hiyoshi’s Lake Biwa work
Hiyoshi began as a wastewater-treatment service company in 1955, with a stated policy of creating a “symbiosis society of human being and nature.” Its initial work centered on maintaining and managing wastewater treatment before the company added water and sewage analysis; its activities later expanded into air-condition analysis.

A major trial came in 1977, when the company worked to recover clean water in Lake Biwa after red tide linked to synthetic detergent. Residents, particularly housewives, stopped using synthetic detergent, Hiyoshi was entrusted with measuring whether the water met cleanliness criteria, and the company also managed septic tanks.

“We started job history as waste treatment service in 1955. Its policy is ‘Create symbiosis society of human being and nature’,” said Tadashi Suzuki, CEO of Hiyoshi. ANI News
India becomes the next focus
According to the report, cooperation requests to protect clean water have come from Asia and the United States, and 1,110 overseas researchers from 53 countries visited to study Hiyoshi’s technology. ANI News
Hiyoshi is now paying attention to India, where the company says environmental awareness is rising alongside economic growth. The company said it wants to transfer environmental-protection technology to India and cited increased rainfall as a reason for water and sewage systems to have greater capacity. ANI News
“Environment=water or air does not have country border. That policy adapted to human resource exchange,” said Suzuki. ANI News
The report said Hiyoshi has decided to focus on environmental protection in Japan, India and other countries, but it did not announce an Indian project, a local partnership, an equipment order or a project timetable. ANI News
Specification Read
No project flow, plant capacity, population equivalent, influent quality, treated-effluent standard or implementation schedule was reported, so the event cannot be converted into m³/day or sized as a wastewater plant. ANI News Operators and buyers would therefore need a measured flow, BOD and COD concentrations, current treatment configuration, discharge requirements and intended project stage before comparing equipment or service scope.
For a conventional municipal wastewater train, the normal sequence runs from screening and primary treatment through biological treatment—such as A2O, MBR, MBBR, SBR or UASB—and then to tertiary treatment or disinfection. Integrated treatment options can help buyers frame that sequence during early scoping. DAF may be relevant where floatable contaminants require clarification before biological treatment or for solids separation. DAF flotation systems
Hiyoshi’s reported work in Lake Biwa measurement and management bears most directly on monitoring, wastewater-service management and water-quality assessment rather than proving that any particular process configuration has been selected in India. ANI News
If your plant looks like a municipal or industrial facility with a defined flow in m³/day, elevated BOD/COD, hydraulic variability and tightening compliance pressure, this announcement means a potential technology discussion may be developing, but not that a project, order or performance guarantee is available. The reported scale does not include the flow, loading, treatment capacity or compliance threshold needed to select an equipment configuration.
FAQ
What Indian wastewater project has Hiyoshi announced?
The report says Hiyoshi wants to transfer environmental-protection technology to India, but it does not identify a plant, municipality, industrial customer, local partner, contract or project location. Buyers should treat the announcement as market-development interest rather than a procurement opportunity until a project and scope are disclosed. ANI News
What capacity will the proposed Indian system handle?
No capacity was reported in either m³/day or population-equivalent terms. Hiyoshi said increased rainfall in India means water and sewage-system capability must be greater, but the report did not provide baseline flows, future flow forecasts, peak demand or a capacity-expansion target. ANI News
How should a buyer select a treatment supplier?
The reported information is not sufficient for supplier selection because it provides no project flow, BOD/COD profile, treated-effluent requirement, implementation schedule or commercial terms. A buyer should obtain the duty flow and loading, required treatment outcomes, site constraints and commissioning program before comparing biological systems, tertiary treatment, disinfection or solids-handling equipment. ANI News
What cost and lead time should be budgeted?
The report did not disclose capital cost, operating cost, lead time, payment terms or a target completion date. Those inputs would have to be developed through site-specific design and supplier quotations; no defensible cost range or delivery schedule can be derived from the reported information. ANI News
