Lessons from Singapore: Mayor seeks to reduce evaporation at lakes

Following their visit to Singapore, Mayor Shraddha Jadhav and civic group leaders of political parties claim to have found the solution to minimise the rate of evaporation of water from the six lakes that supply water to the city.
Their solution to the problem is to replicate the measures being taken by Singapore.
The Public Utility Body in Singapore, in charge of all the essential services, uses an organic palm oil-based solution and mixes it with the water to form a layer of oil on the water.
“The layer that is created prevents evaporation of water. We have asked the civic administration to study it, and if feasible, it can be implemented,” said Jadhav.
Currently, 15-18 per cent of water is lost due to evaporation.
“This solution is organic and has no health hazards,” said leader of the House Sunil Prabhu.
They have also suggested that the municipal corporation consider exploring the option of an off-shore desalination technique.
In this, the desalination plant is setup on a barge, which is floating in the sea, and can be moved to any part of the coast when the need arises.
“Setting up a desalination plant on shore will need a lot of land and will take at least 5 years, but the off shore will take just two years,” said Rahul Shewale, standing committee chairman.
But the only problem in the technique is that the cost of treating the water works out to Rs 70 per 1,000 litres, which is exorbitantly high.
The city is facing a 15 per cent water cut for the last one year.
The minimum requirement of water in the city is 2,900 million litres of water daily as against a demand of 4,200 million litres.
Currently, the water stock of all the six lakes is 1.44 lakh million litres, as opposed to 1.49 lakh last year.
