SFC to Power 424 MLD STP in Ahmedabad One of the World’s Largest SBR-Based Installations
We are proud to share that SFC Environmental Technologies Ltd. has been awarded the technology order for one of the largest Sequencing Batch Reactor (SBR)-based sewage treatment plants in the world—424 MLD capacity, currently under development at Pirana, Ahmedabad, by Larsen & Toubro Limited.
The project represents a landmark in scale and strategic urban importance, and further strengthens the leadership of C-Tech®, SFC’s flagship SBR technology, in the Indian and global wastewater treatment space.
Setting New Standards in Scale and Efficiency
The Pirana STP will deploy our proven C-Tech® SBR platform, trusted across 1,200+ reference orders worldwide. The fully automated biological process integrates aeration, clarification, and sludge stabilization in sequential cycles—offering:
• High-quality effluent suitable for discharge or reuse
• Significant power savings over conventional ASP systems
• Modular scalability and low footprint
• Simple operation with long-term reliability
A Project of Strategic Urban Significance
The 424 MLD Pirana STP is being developed under the Gujarat Resilient Cities Partnership Programme (GCRP) with funding support from the World Bank, and executed by Larsen & Toubro Ltd.
It is part of Ahmedabad Municipal Corporation’s broader strategy to reduce the discharge of untreated sewage into the Sabarmati River, which currently receives over 600 MLD of untreated flow.
Once commissioned, the facility will make a major contribution to river pollution abatement, improved urban hygiene, and public health outcomes for the city.
Strengthening Long-Term Partnerships
We are honoured to support Larsen & Toubro, one of India’s most respected engineering and construction firms, in delivering a project of this scale. This collaboration underscores SFC’s role as a reliable technology partner—focused on engineering excellence and operational simplicity.
Our Commitment to Enable Sustainable Impact
At SFC, we remain focused on empowering our customers with advanced, proven, and cost-effective environmental technologies. From C-Tech® SBR systems to new-generation membrane and reuse technologies, we continue to build solutions that are simple to operate, energy efficient, and scalable to the needs of modern cities.
The Pirana STP project is not only a milestone for us as a company, but a testament to India’s growing investment in sustainable urban infrastructure.
We look forward to delivering this iconic project with the same precision, performance, and partnership that define SFC’s legacy.
