Water is one of the essential elements of the human body. The quality of drinkable water plays a tremendously important role in human health. Access to drinkable water in developing countries is one of the toughest challenges that need to be addressed. One-third of the world population does not have access to clean water sources and most of them in rural areas with limited infrastructures and resources. This problem is significant to the people those are not connected to the electrical grid thus, they lack to access safe/drinkable water supply. Unsafe water and poor sanitation cause 80% of all diseases in the developing world. A country like India, who has a tremendous amount of natural water resources but, because of the ecological disturbance caused by industrialization and other causes created the crisis of drinking water.
There is the innumerous amount of research going on towards the purification process and enhancement of quality of drinking water. Reverse osmosis is one of the well-known and practiced water purification methods which need electricity to be operated. The same purification process has a considerable demerit i.e. two-third part of water wastage to clean the semipermeable filter which is essential in this process. There are some other water purification methods which exclude the demerit of water wastage but still consume electricity. Most of the water purification devices are costly and not reachable to poor people. The current consumption of water and energy in the world are very high so, it is very important to peruse research towards the process which can avoid water & power waste and low cost as well so that it should be reachable to the poor people.
National Mission on Himalayan Studies (NMHS) is an initiative of Ministry of Environment, Forest & Climate Change (MoEF&CC) under which IIT Mandi has a project entitled “Development of Low Cost Accelerated Water Purification Systems with Added Mineralisation for Himalayan Region”. The project aims in the development of simple, low cost accelerated high-quality water purification system using solar thermal energy with added minerals from locally available materials for off-grid applications. Following are the major heads of this project-

Following are the major heads of this project-
- Development Solar Thermal Energy (STE) powered water purification suggests itself be one of the solutions in areas with high sun radiation like India.
- The current consumption of water and energy in the world are very high so, it is very important to avoid wastage therefore, we try to use the most efficient technique to develop a system which can avoid water and energy consumption. This would further lead to the mass development.
- Application of solar thermal energy other renewable energy sources for the design of an accelerated system.
- Application of nanotechnologies in the field of water purification system would incorporate nutrients into the water.
