The water to maintain these places would be higher than our domestic needs as it includes bathing the animals, maintaining the water sources for reptiles and fish, and drinking water. In the case of Vandaloor zoo, which has 1,500 acres of forest land, the consumption of water is 3 lakhs to 4 lakhs litres a day.
Sudha Ramen, deputy director of Vandaloor Zoo said, “Over the years, many water harvesting structures like percolation ponds(PP), rainwater pits have been installed here.
The PPs have helped us recharge the groundwater levels. There are about 13 open wells inside the zoo which supplies water all through the year.” She added that the Palar water supply to the zoo has reduced, so these deep wells have been supplying water during peak summer.
R Rajarathinam, director of snake park said that the park stopped depending on Corporation water 10 years ago and has completely shifted to borewells. “We require 7000-8000 litres of water per day, which borewells are providing.
T Murugesan, forest ranger associated to Guindy National park said that they regularly do maintenance of borewells and they supply 10,000 litres every day.
