Packaged Sewage Treatment Plants (Johkasou)
Decentralized STP systems available across a range of capacities, engineered for residential societies, commercial complexes, industrial units, and institutional campuses.
JOHKASOU
Johkasou is a Japanese decentralized sewage treatment system that treats wastewater at the point of generation, rather than transporting it long distances to centralized treatment plants.
Each unit combines a purification structure capable of treating both black water (sewage) and grey water (sink, bath, laundry wastewater), producing treated water suitable for safe discharge or on-site reuse.
Key Features
- Compact and modular design, suitable for homes, hospitals, schools, hotels, factories, and townships
- Low maintenance and long operational life, engineered on decades of Japanese field data
- Fast deployment — ideal for both new construction and retrofit applications
- Treated water can be reused for toilet flushing, landscaping, and road cleaning
- Reduces dependence on freshwater sources and helps arrest groundwater depletion
- Customizable to meet local regulatory and discharge norms

Turn Food Waste Into a Resource.
- Offers high-load and expeditious treatment, and is easy to maintain.
- Nitrogen can be removed through its anaerobic filter chamber.
- The sedimentation chamber can hold large concentrations of sludge. It is sufficient to draw the sludge.
- Comes in three styles and body types (capsule tank, cylindrical tank of Ø2170 and 2500 mm) and therefore can meet various water quality criteria and installation space requirements.
- Energy-saving blowers keep running costs low.
- The latest automated machinery ensures stable, high-quality product manufacturing.
- Capacity can be increased as per the development speed.
