Artificial Recharge Technique in I.S.M.
• Roof Top Harvesting- In this Technique the top of the roof of the buildings in I.S.M. are used as the catchment area of rain water for harvesting using artificial recharge techniques.
Need for Augmentation and Management of Ground Water Resources within I.S.M.
• Steep increase of human population in the campus.• High water demand expected due to increase in developmental works and expansion
program. • Conservation and management of available resource to meet the growing needs.
Supply Status of Water in I.S.M. Campus:
Sr.No. Tube Well No. Location
Discharge/Hr. (Litre) Pumping Hrs
Total Discharge/ Day
Units Cosumed/Day
1 Dug Well No. 1 Near Ruby hostel 15000 10 150000 55.95
The study estimated that about 83% of total volume of groundwater available is consumed and thereby maintaining a balance of about 17%. -------------------------------------------------------------------------------------------------------------------------------------------------------
Concluding RemarksThe study revealed a mean rise of 2.29m in the groundwater during the year 2014.
This figure of groundwater resource balance is expected to improve over the years with continued monitoring study of the fluctuating trend of the groundwater levels with rain water harvesting implemented and last but not the least, an effective groundwater management.
Total replenishable volume of water recharge = (Area x fluctuation x 0.03) + Total draft during the period
Here, 0.03 is the specific yield considered for hard rock as per GEC, 1997
So, The volume of water recharged is 144270 m3 x 1000 = 144,270,000 liters
Consumption from ground water for the study period is 19,54,000 x 7 x 30 = 410,340,000.00 liters
Total Resource:- 410,340,000 + 144,270,000 = 554,610,000 liters
