The Indian Army’s Trishakti Corps has taken another step toward environmental conservation in Sikkim by commissioning a modern Sewage Treatment Plant (STP) at Changu. The facility is aimed at improving sanitation and managing wastewater sustainably in the challenging high-altitude environment.


The plant uses indigenous technology developed by the Bhabha Atomic Research Centre (BARC) and has been designed to function efficiently despite the region’s difficult weather and terrain. The facility was inaugurated by Pamin Lepcha, MLA of the Gnathang-Machong constituency, in the presence of Army personnel and other local stakeholders. The project highlights the growing cooperation between the military and civilian administration, with both sides working toward improving environmental protection and community welfare.

With the new facility in place, wastewater can be treated more effectively before it affects surrounding water sources. The use of locally developed technology also supports the Aatmanirbhar Bharat initiative and showcases how Indian scientific expertise can be adapted to meet environmental needs in remote and difficult locations.

Tsomgo, also known as Changu Lake, is an important natural landmark in Sikkim and has considerable cultural and religious importance for local communities. Protecting the lake and its surrounding ecosystem is therefore crucial not only from an environmental perspective but also for preserving the region’s cultural heritage.

A senior Army official said that protecting the environment and respecting local traditions remain important elements of the Army’s engagement with the people of Sikkim. The official noted that combining indigenous technological solutions with community participation can help protect water resources and preserve the region’s natural environment for future generations.

The initiative is part of the Indian Army’s wider efforts to promote sustainable development and environmental responsibility while maintaining its close relationship with communities living in Sikkim’s remote areas. The Trishakti Corps has also undertaken initiatives aimed at improving communication and access to information in border communities. In April, it established 88.4 FM Radio Sikkim Sundari, described as Sikkim’s first Border Village Community Radio Station, in East Sikkim.

The community radio initiative was designed to address the communication difficulties faced by residents of remote high-altitude villages, where geographical isolation, extreme weather and limited mobile and internet connectivity can restrict access to timely information. The station aims to help bridge this gap by providing dependable local communication and information services.
