Trees are recognized as natural solutions for ground water recharge.Environmentally Sound Techniques (EST's) in harnessing storm water by trees and drains are viable tools in the urban ecosystem. Empirical and Field Studies are conducted on ecological niche of trees for two campuses in Bengaluru, India. Trees having 200 mm girth above ground level were chosen for Environmentally Sound Technology at no cost for recharging purposes. Trees with deep root system and canopy included, Ficus bengahalensis, Ficus religiose, Azadirachta indica, Tamarindus indica, Swietienia mahogani and Terminalia arjuna. Laboratory studies were conducted, Porosity of soil was recorded as 0.49. The rate of percolation was found to be 3.84*10^-3cm/sec by direct impact test. The average static water levels for the study area for the year 2011 was 30.32m and 32.69 m in 2017. Over all rainfall data for 100 years reveal adequate rainfall for potential harvesting. The ground water yield in the area was 5 liters per second. Climate resilient water security was evident for an integrated deployment of EST of integrating trees and percolating drains as conjunctive means to recycling and rain water harvesting.
