The last three days rainfall pushes Morbe dam of Navi Mumbai Municipal Corporation over 83 metre but this is far away from the overflowing point. The dam which supplies water to Navi Mumbai area overflows at 88 metre.
The catchment area of Morbe dam received 214 mm rainfall in the last three days and the current level of the dam of the dam 83.25 metre. With the monsoon is likely to start withdrawing in a week time, there is very less possibility that the dam will be filled to its capacity. The dam which is situated in Khalapur in Raigad district supplies water to city round the year and it is filled upto 95% to its capacity.
The maximum capacity when the dam overflows is 88 metre and till Monday afternoon, the level of the dam was 83.25 metre. “The shortfall of around 4.75 metre is unlikely to be filled in rest of the season,” said an NMMC official.
The catchment area of Morbe dam received a total 3010.80 mm rainfall till Monday afternoon. According to civic official, around 3500 to 4000 mm rainfall is required in the catchment areas to overflow the dam.
As per the met department, the condition is becoming favourable for withdrawing of monsoon and in week time, it will start. “The last lag of rainfall will push the dam level up but the shortfall of around 5% cannot be covered up,” said the official.
This year, city has received better rainfall than last year. However, it is below than the average of last five years. Till Monday afternoon, the city has already received 2400.54 mm rainfall across the city while in 2015, the total rainfall was just 1409 mm. In the last five years period, maximum rainfall was recorded in 2013 when the city received a total 3295mm rainfall and the same year, the dam was overflowed.
This year, there was delay in arrival of monsoon. However, later it picked up. But the shortfall remains a matter of concern. City residents have already been witnessing water cut for the last six months. And, the end of the monsoon, more clarity will come of water supply status.
According to disaster management department of Navi Mumbai Municipal Corporation (NMMC) which records rainfall, the current status of rainfall is recorded from June 8 when the monsoon normally arrived in the city.
Now, the civic body follows the Indian Meteorological Department’s norms and records rainfall from 8.30am of the present day till 8.30am the next day.
