Rapid urban growth, scarce water resources and a high risk of natural disasters pose serious challenges for Leh's urban planning and governance.

Across South Asia, small and medium-sized towns are rapidly expanding. Urbanisation has made inroads into the entire Himalayan region. Mountain urbanisation poses a need for assessments of emerging risks and vulnerabilities in environmentally sensitive regions. These areas are marked by population growth and migration from rural settlements as well as limited availability of suitable space for construction, often leading to building activities in landslide or flood-prone areas.

Hi, We have a capacity of one lac ltr of STP installed in the building. The STP is working in good condition, but we are facing an issue. The output of STP is one lac ltr per day but the usage of the same can be done in 2 areas, i.e. flushing and gardening. 40,000 ltr is used in the above areas. Where to put the rest 60,000 ltr water? Where the rest of water can be consumed? What measures can be taken with the rest 60,000 treated water? It can be used in increasing groundwater levels too? Thanks
