Groundwater Recharge

The Preliminary Consolidated Report on the Effect of Climate Change on Water Resources, prepared by the Central Water Commission and the National Institute of Hydrology, under the guidance of the Ministry of Water Resources in 2008, is one of the first official reports made available by the Government of India, of a reliable quantitative assessment based on field data, of the likely effect of climate change on the availability of water resources, i.e. on the glaciers and snow melt, on rainfall and their effect on run off into the river system and their contribution to ground water. In the Report, an attempt has been made to give a brief account of the available studies on possible impacts of climate change on India's water resources, change in India's water needs, climate of India, river basins of the country, present water resources and future demand and supply, impacts of projected climate change and variability, and associated hydrological events and likely vulnerability of regional water resources to climate change. Identification of key risks, research needs and prioritisation of mitigation strategies has also been discussed.

Bangalore's sprawling expansion outpaces the public utility's ability to accommodate skyrocketing demand for water and sanitation services, and it is increasingly common for new residential communities to assume total management for their own water and sanitation services through their resident welfare associations.

We at the Water Portal, came up with some questions to ask the builder when you are buying an apartment. The more educated you are regarding the way the apartment is handling water, the better decision you are likely to make and one that will benefit you immensely in the long term.

"Water MOVES"is a quarterly newsletter from Society for Promotion of Wastelands Development. This issue contains an article on Integrated Water Resource Management by N.C.

This is a photograph of water recharging done around a water source (like borewell). This is being implemented in some primary schools of the area.

Mr. R.V. Rama Mohan of Center for World Solidarity has come up with freeware (an Excel spreadsheet) to calculate the groundwater extraction vs. recharge in an area. He has made the software available to the public and is soliciting feedback.

Attached is an interesting document from Prof. Prithvi Kandhal about using porous asphalt in parking lots so that rainwater seeps through it and recharges groundwater.

Dr. Kandhal has published many papers and has significant credentials in his areas of expertise. He resides in Jaipur after 35 years of working in the US.
