Delegation from Leh visits IIT Gandhinagar to understand wastewater management in extremely cold climate

A 13-member delegation from Leh-Ladakh and Kargil visited the Indian Institute of Technology (IIT), Gandhinagar to understand the wastewater management at the institute, learn more about the process and examine various environmentally friendly technologies. environment and sustainability that can be adopted for the extremely cold climate of their region, officials said. Delegates discussed issues of high-altitude infrastructure development, particularly water supply and sanitation during Wednesday’s visit. The IIT team led by Sudhir Kumar Arora, Professor, Civil Engineering, made a presentation on ” Management of Domestic Wastewater in Various Climatic Conditions: Finding Sustainable Solutions ” which highlighted various technical processes, construction, the operation and maintenance aspects involved in treating different types of wastewater, including natural, biological and physicochemical. The team also explained the sustainable technology used in the IITGN wastewater treatment plant.

As part of this system, the wastewater is routed to the Wastewater Treatment Plant (STP), where it is treated by feeding the collected waste to a bacterial mass that converts the decomposing material into a mixture of stabilized base of water, carbon dioxide and mineral-rich residues. This process is completed by passing the effluent through a settling tank, an anaerobic baffle reactor including anaerobic filters, and through the roots of Canna Indica in a process known as root zone treatment. The resulting treated water is mainly used for irrigation purposes, ” a senior official said. “In addition to the direct benefit of saving the operating costs of the wastewater treatment system, the energy and chemical consumption of this technology results in a smaller carbon footprint. Therefore, it can also be referred to as “STP green technology”. The technology reduces the demand for freshwater supply and the load on the city’s wastewater treatment system, ” the official added. The delegation included administrative officers and advisers from the Autonomous Council for the Development of the Hill of Ladakh (LAHDC), elected representatives from the towns of Leh and Kargil, the chairman of the Block Development Council, executives and neighborhood members. municipal committees of Leh and Kargil, engineers of their public health. Engineering and Urban Planning Department of the Ladakh Ecological Development Group (LEDeG).
