Water: The Drop of Life
DEFINITION OF THE PROJECT:
WATER MANAGEMENT SYSTEM IN DELHI –
-GIVING A NEW LIFE TO RIVER YAMUNA, THUS TO DELHI…
…BY THE AUGMENTATION OF GROUND WATER BY RAIN HARVESTING UNIT.

Pushkarni at Loni Bhapkar
CONTINUING TRADITIONS AND TECHNOLOGIES:
Aside from archaeological examples, water harvesting structures continue to be maintained by endogenous communities all over the country. Groundwater continues to be drawn from aquifers or palaeo channels in Rajasthan through bardi (shallow wells in depressions), tankas, khadin and johad (underground storage pits), kunds (cisterns in catchments), beris (wells on river beds).
View of udaigiri caves showing a tank
Udayagiri consists of two hills joined together with a low ridge or a saddle. The hills are aligned northeast-southwest, forming a crescent-shaped pocket in the west with ancient
The western end of the passage leads to a high embankment of a tank, two sides of which are formed by two sides of the northern hill divided by a valley. There are three other tanks and two major channels apart from minor drains forming four independent water systems at Udayagiri
Rain water harvesting system advantages
Urban centers in India are facing an ironical situation today. On one hand there is the acute water scarcity and on the other, the streets are often flooded during the monsoons.
The system consists of a collection tank, slow sand filtration, and a “living systems” componentwhich uses aquatic plants and fish to purify the water. The rainwater collection basin is located on the roof of the Farm Centre and integrated with the existing roof structure and drainage systems.
Parapet wall has been given corrugated profile to facilitate more quantity of rain flow to the gutter
ADJACENT TO VIKAS MARG, NEAR ITO,
LOCATION: Hathi Shala, adjacent to Vikas Marg, near ITO, Delhi
AREA: 1.2 sq km
The river bed area in Delhi is 97 sq km. The whole of it is coarse sand up to a depth of 40m. This feature is the key to the riverbed recharge capability!!

To the Poor
The atharvaveda invokes mother earth to yield the life giving water to those of pure conduct and right means , and to punish water polluters in these words:
शुद्धा न आपस्तन्वे क्षरंतु, यो नः सेदुरप्रिये तं नि दध्मः I
पवित्रेर्ण पृथिवी मोत पुनामि I I
