Geological records point out to a period of aridity 10,000 years ago, at the end stage of Pleistocene glaciation, which gradually changed to a wet phase. Copious rainfall in the Himalayan region gave rise to innumerable rivers, mainly Saraswati river along with six other rivers which flowed down in cascades bringing enormous amounts of water in the plains of Punjab, Rajasthan and north Gujarat.
On or after the commencement of the Bangalore water supply and sewerage (Amendment) Act 2009 every owner or occupier who has constructed building in the site area 2400 square feet and above whether for residential/non residential/Government/commercial and any other purposes shall provide rain water harvesting structures within nine months from the date of commencement of the amendment Act 2009, in

Water crisis in Jamshedpur
Availability of groundwater varies spatially and temporally depending upon the terrain. The scarcity of water affects the environmental and developmental activities of an area. Construction of small water harvesting structures across streams/watersheds is gaining momentum in recent years.
The issue of upstreamdownstream water balance is an important one and there is a need to understand the feasibility of water harvesting and groundwater recharge in upstream areas. Kumar et al (EPW, 30 August 2008) highlight this issue, but they overemphasise the negative aspects.
Shyam Ranganathan KARAIKAL: Groundwater recharge and conservation of Cauvery water are important for the tail-end region of the delta.

Being close to sea, Karaikal does not have good groundwater supply due to seawater intrusion.
CHENNAI: The State government has decided that no more approval of applications for installation of artificial recharge structures be given unless 50 per cent of the cases sanctioned earlier set up the facility, S. Audiseshiah, Principal Secretary (Public Works), said on Monday.
Sediment deposition as a result of soil erosion is a significant problem in the village water tanks. In order to increase the rainwater storage capacity, removal of sediments from water tanks was taken up under the State Government Water Conservation Programme in Medak District, Andhra Pradesh, India.
