Officials say that a 13-member delegation representing Leh-Ladakh, Kargil, and other countries visited Gandhinagar’s Indian Institute of Technology (IIT), Gandhinagar, to learn more about wastewater management and to examine sustainable and eco-friendly technologies that can be used in the harsh climate of the region.
During Wednesday’s visit, the delegates addressed the issue of high-altitude infrastructure development, including water supply and sanitation.
Sudhir Kumar Arora, Professor of Civil Engineering, presented a talk on “Management Of Domestic Waste Water in Diverse Climatic conditions: Search For Sustainable Solutions”. This presentation highlighted the various technical aspects, construction, operation, and maintenance involved in treating different types of wastewater, including biological, natural, and physicochemical.
The IITGN sewage treatment plant was also described by the team.
The waste water is piped from the system to the Sewage Treatment Plant, where it is treated with a bacterial mass. This converts the decaying matter to a stable basic mixture of water and carbon dioxide, which then produces a mineral-rich residue. The effluent is then passed through a settlement tank and an anaerobic baffled reaction unit with anaerobic filters. Finally, it is sent through roots of Canna Indica, a process called root zone treatment. According to a senior official, the treated water is used primarily for irrigation.”
This technology has a lower carbon footprint than other technologies. It also saves the operation cost of the sewage treatment plant. It can be called a “Green STP Technology” because it uses less power and chemical consumption. According to the official, the technology lowers the demand for freshwater supply and reduces the burden on the city’s sewer treatment system.”
This delegation consisted of administrative officers and councillors from the Ladakh Autonomous Hill Development Council. They also included elected representatives from Leh, Kargil, and the Chairperson of the Block Development Council.
