The water crisis that dogged the city for more than two years due to failure of monsoons may be over but water managers are worried over the huge evaporation loss due to the soaring temperature.
A Water resources Department official said that the city has nearly 7tmc feet of water in its four reservoirs which could last for the next five months. Interestingly, last year during the same time, the city had only 2.7tmc feet of water.
“Usually, the city requires one TMC feet of water per month. But taking into evaporation losses, the water in the reservoirs could last till the next five months,” said a senior water resource department official.
Usually, the evaporation loss is calculated at 20 per cent but with the hot summer, the calculation is now at 30 per cent. Taking into account the evaporation loss, the water in the reservoir could last for the next five months, said the official.
Interestingly, Chennai Metro water which had cut down its supply for the last two years has now started supplying 830 MLD of water. Prior to the heavy rains in December, the city was getting only 535MLD of water.
Meanwhile, Water Resources Department officials have written letters to their counterparts in andhra Pradesh to supply Krishna Water. “We are holding discussion with the officials. But their reservoirs have nearly dried up. We are pinning our hopes on rains which is expected in the month of June,” said the official.
