Pillars of the overhead water tank inside Zoo develops cracks: Poses safety issues

Zoo needs around 5 to 5.5 lakh litres of water every dayExpress

In century-old Sri Chamarajendra Zoological Gardens in Mysore cracks have appeared on the pillars of the overhead tank which was constructed wayback in 1978. The tank having a storage capacity of 1.5 lakh litres of water is situated close to a Nursery and is posing threat in case it crashes.

The tank appears to be in a dilapidated condition and according to zoo sources not much water is stored in the tank. Chunks of concrete have fallen off from underneath the tank exposing rusted iron rods. The concerned authorities should take appropriate measures immediately before any mishap occurs.

Within the Zoo premises there are four over head water tanks and one sump. While the storage capacity of three water tanks is 1 lakh litres, the one near the nursery which has developed cracks is 1.5 lakh litres. The sump has a capacity to store 2 lakh litres. The water tank near the enclosure housing the Hippopotamus was build in 2006 while the other two water tanks were constructed in 1985.

About water facility

The Zoo needs around 5 to 5.5 lakh litres of water every day, out of which MCC supplies about 2 lakh litres. About 1 lakh liter is preserved in case of any emergency.

The major portion of water stored in these tanks comes from borewells already dug within the zoo premises. There are six borewells, one of 10 HP capacity; four of 7.5 HP and the remaining one of 5 HP. Supply of water from these borewells is quite sufficent to meet the daily requirements of the zoo's.

Speaking to Express, Zoo Deputy Director NT Vijayakumar said, `within two month tenders will be called and the present tank will be demolished,' while a new tank with the same storgage capacity will be built.'

Zoo Engineer Muralidhar said that `Till the construction of new water tank is taken up, we have to depend on the existing water tank for storage. There is no immediate threat of it collapsing and can be managed for some more time. Plans are there to have another water sump with a storage capacity of 2 lakh litres.'
