Project Information
- Project Name:Paikpara Govt. Officers Building
- Category: Johkasou STP
- Capacity: 1050 m³/day
- Location: Paikpara, Mirpur 1
- Client: Bashundhara Group
Details Of This Project
Unissol Group is one of the leading STP suppliers in Bangladesh. We have successfully implemented a Johkasou Sewage Treatment Plant (STP) at the Paikpara Govt. Officers Building, located in Mirpur 1, Dhaka. This project features a high-capacity STP system with a treatment capacity of 1050 m³/day, designed to handle large volumes of domestic wastewater efficiently.
The Johkasou STP system installed in this project is constructed using fiber-reinforced plastic (FRP) modules, ensuring durability, corrosion resistance, and long operational life. Multiple blowers are used to support the aeration process, while pumps transfer raw wastewater from the collection tank into the treatment system. After treatment, the water is further clarified before being safely reused for gardening and landscape irrigation within the premises.
This project reflects our strong commitment to delivering reliable, eco-friendly, and sustainable wastewater treatment solutions for large residential and government facilities across Bangladesh.
Features of This STP Project
Process Flow of the STP
The Johkasou STP at the Paikpara Govt. Officers Building follows a systematic and efficient treatment process:
- Separation Box: Separate solids in wastewater by gravity and prevent the agitation of the excess sludge in Sedimentation & Separation Chamber by influe
- Separation & Sedimentation Chamber: Separate solid debris or impurities from water in influent and circulated water and store these sediments in the chamber. Accumulated sludge should be desludged from the tank periodically at least once in 6–12 months.
- Anaerobic Chamber: It is filled with filter materials, which separate solids and keep anaerobic microorganisms to decompose organic matter.
- Moving Bed Chamber: It is filled with mesh cylindrical media, which retain aerobic microorganisms to decompose and remove organic matter from wastewater.
- Sedimentation Chamber: In order to obtain clear treated water, separate the excess sludge (suspended solids, SS) by gravity. The settled sludge is constantly returned to the sedimentation & separation chamber by the airlift pump.
- Disinfection Chamber: Disinfect the treated water to discharge to the river or other water bodies.
The entire system operates seamlessly, ensuring effective sewage treatment with minimal environmental impact.

Why STP need for everywhere in Bangladesh?
Sewage Treatment Plants (STP) are very important for Bangladesh to keep the environment clean and safe. With more people and industries growing every day, untreated sewage is causing serious problems. Dirty water from homes and factories often goes into rivers and ponds, making them unsafe for drinking, farming, or fishing. This pollution also harms fish and plants.
STP clean this dirty water, removing harmful things before it goes back into nature. Without proper treatment, sewage can spread diseases like cholera and diarrhea, putting many lives at risk. In crowded cities, STPs help manage waste, prevent bad smells, and stop water from flooding the streets. They also protect our natural surroundings and make sure water stays usable for future generations. As floods and rising sea levels become bigger challenges, STPs are needed to keep communities safe and healthy. Investing in STPs is an investment in a better, cleaner Bangladesh.
Bangladesh’s Urgent Need for Wastewater Treatment Solutions
Bangladesh’s rivers, canals, and groundwater are under severe threat due to untreated wastewater discharge. Rapid urbanization and population growth have intensified sanitation challenges, especially in informal settlements.
