Thane plans to desalinate creek water for drinking purpose
THANE: The acute water crisis faced by the city this year has forced the Thane Municipal Corporation to use the vast water source of the city.
The corporation has proposed to desalinate the Thane creek water and use it for drinking purpose. Apart from desalination, a tidal power plant with a capacity of eight megawatt power generation will also be set up.
Both the projects will be set up on public-private participation basis where the corporation will not have to bear the cost.
The city receives 480 mld of water from four sources. This summer, the water available was merely 314 mld imposing a water cut of over 35 per cent in the city. The residents have to face shut down from 48 to 60 hours.
Sunil Pote, deputy city engineer, water department said, “The city has a waste creek, the water from which will be an endless source to deal with the water crisis in the city. The water at most places in the creek is not polluted and can be used for potable purpose. We have proposed to set up a desalination plant to desalinate the creek water and generate 20 mld of drinking water daily.”
This kind of desalination plant has been set up in countries such as Japan, Australia, China, North Africa and European countries. In India the plants have been set up in Gujarat and Chennai.
“A company from Pune has technical expertise in the project and they have shared it with us. The corporation will hire technical experts to research and prepare a detailed project report,” Pote added.
The TMC will spend Rs15 lakh to hire consultants for the project.
It will provide the land and bear electricity cost of the project. The remaining expenses will be incurred by the agency allotted the work.
The company will be responsible to ensure that the potable water fulfills all the required water quality criteria. This water will be connected to the distribution system of the corporation. The company can sell the water to the TMC at the rates finalised by the corporation, the company can also sell few bottled water to remove the maintenance expense of the plant.
TIDAL POWER PLANT TO BE SET UP IN THE CITY
The corporation has proposed to set up a tidal power plant with a capacity of eight megawatt below the pipeline bridge near Kasheli creek. The high and low tides in the Thane creek and Ulhas river generate potential and kinetic energy which can be converted into electricity.
“Most countries have carried out extensive research in using the tidal energy to generate electricity in the last 30 years,” Pote said.
“The tides below the pipeline bridge are as high as 4.67 metres. Tapping the energy of these tides will generate 3.43 crore units of power in one year. This power will be used by the corporation itself for its own properties. The excess power can be transferred to the grid of the power companies,” he said.
