The 7.5 MLD Sewage Treatment Plant (STP), located along the banks of the Ganges in Rishikesh, is a pioneering project that addresses the pressing need for efficient wastewater management in this sacred region. As India’s first vertical STP and part of “Namami Gange” project, this innovative facility was inaugurated by our esteemed Prime Minister, Modi Ji, marking a significant milestone in sustainable infrastructure.

Due to space constraints in the area, the STP is ingeniously designed in a vertical manner, comprising four stories that optimize limited land use. At the base of the structure lies a 23-meter diameter equalization tank, which serves as the foundation for the secondary clarifier, also measuring 23 meters in diameter. The third story houses essential components of the treatment process, including an anoxic tank and an aerobic tank, both sized at 6 meters by 6 meters with a side wall depth of 6.4 meters. Additionally, an aeration tank measuring 7.1 meters by 8.5 meters with a depth of 6.1 meters is included to enhance biological treatment efficiency.

This plant employs MBBR (Moving Bed Biofilm Reactor) technology, complemented by a tertiary disc filter, ensuring high-quality effluent treatment while maintaining environmental standards. Our team provided economical and optimized structural consultancy for this project, focusing on innovative solutions that meet both operational needs and space constraints.

The establishment of this vertical STP not only enhances Rishikesh’s wastewater management capabilities but also contributes to the broader goal of preserving the Ganges’ purity. By implementing such cutting-edge technology and design, we are proud to play a role in promoting sustainable practices that benefit both the environment and local communities.
