An innovative project makes rainwater harvesting easier and more effective in certain areas of Mewat village with increased groundwater salinity.

One of the major causes of deterioration of water quality is the increase in overall salinity. Total hardness and the presence of materials like fluoride, nitrate, iron, arsenic, and toxic metal ions determine salinity levels in groundwater. With the demand for groundwater growing rapidly, its exploitation is also accelerating which causes depletion. Depletion of groundwater changes the flow (both direction and velocity) of the groundwater which may cause the inflow of polluted water into the freshwater aquifer from surrounding areas.

Datameet and Centre for Internet and Society have released a prototype web app that allows users to access daily rainfall data from Jan 1981 till Dec 2017 for a watershed of their interest.

Understanding water in all its forms in every part of the water cycle is vital to ensuring its sustainable and equitable management. Whether there is a scarcity of water or an excess of it, knowing precisely the quantum of water, whether underground in aquifers, embedded in the soil as soil moisture or in numerous lakes, reservoirs and rivers is vital. Knowing where and to what degree water is consumed, in agriculture or water thirsty cities and industries is equally essential to encourage judicious use of the resource.
