Mangaluru: Transforming sea water into fresh one - city team to visit Chennai


Daijiworld Media Network - Mangaluru (SP)

Mangaluru, Feb 9: The proposal that had been mooted about 18 months back to supplement water supply system of the city by drawing water from Arabian sea and providing it to the citizens after treating and converting it into fresh water, has got a fresh thrust. A team of over 30 persons drawn from city corporation and other departments has undertaken study tour of Chennai relating to this proposal, to study for themselves the efficacy of such a system already in place at Chennai.

Like many other cities, Mangaluru has often encountered shortage of water particularly during summer months, although it is in a better position as compared to other cities in the state as far as drinking water supply is concerned. The level of water at Thumbe dam has been risen to six metres this year. It is being claimed that the city will not face shortage of water during this summer. However, many feel that any shortfall in rain, execution of Yettinahole project, and entry of new industries will have adverse impact on the drinking water supply situation here.

A few cities and also mega projects located nearer to the city have done experiments with reverse osmosis system to get potable water by treating sea water. Sensing that this could provide a lasting solution to the water shortage problem, a team has been deputed to Chennai to get on hand experience about advantages and disadvantages of such a project and practicability of installing a plant to convert saline water into fresh water in the city.

The idea of processing sea water for consumption had been mooted by the then deputy commissioner of Dakshina Kannada district, A B Ibrahim, at a meeting of leading industrialists from the city on May 25, 2016. The then urban development minister, R Roshan Baig, too had evinced interest in the project and suggested to depute a team to Chennai to study the prospect of installing a processing unit here.

Chennai already has sea water desalination plant, and processed water from the plant is being supplied to the citizens of Chennai. The team headed by city mayor, Kavitha Sanil and commissioner, Mohammed Nazeer, left for Chennai on Friday night. The team has four officials, corporators, and four nominated members of the council. The team will undertake a three-day tour and return on the evening of February 12. The cost of the team's travel, food, and stay will be footed by the city corporation.

City corporation commissioner, Mohammed Nazeer, said that around Rs 871 crore has been set aside in the budget for processing sea water to tackle water shortage encountered in the city during summer months and that the current visit is to assess the possibility of processing sea water in the city. Mayor, Kavitha Sanil, who asserted that the city will not face water problem this summer in view of abundant stock at the vented dam, expressed the opinion that there is a need to make sure that in future too the city will not suffer from water shortage, and that the current study tour is meant to study the pros and cons of installing the sea water processing unit in the city.

    Our costal region is still blessed with rain and situation is not like chennai or gulf where there is scarcity of rain. Try to store this nature given desalination water instead of spending our tax payer's money..

    Converting the sea water into drinking water thru the Reverse Osmosis System is no doubt a costly venture, but so long as India can manage their own technology thru their own expertise and resources, the ultimate result will be highly beneficial for a country such as India where water will always remain to be in short supply due to uncertainty of monsoons and ever=increase in demand.

    Desalination of sea water is an expensive thought but so long as India can manage their own water conversion and distribution this will prove to be highly beneficial to India in the long term. Our agricultural in India, and our daily consumption of water will continue to increase regardless of how much we conserve our daily usage.

    Development of Sea Water desalination in India is a bold but valuable step in the right direction. Water will always remain to be a precious commodity in India.

    Chennai,Dubai plants generally in continuous operation.In Mangalore the plant may be required only when the river water level goes down in peak summer.If so then they have to see the viability of maintenance cost to keep the plant machinery ,RO membrane,intake pipes etc. in keeping idle for most of the time.

    The dam/ reservoir built at Kudremukh is not being used for slurry movement any more. What is happening to the water in that reservoir.
    Just like that reservoir why not build another 3 or 4 dams/reservoirs and there will be enough of water for mangalore for the next 2/3 decades.
    surely a well constructed reservoir can last for years and cost much less?

    I call for others to give their views on this

    It OK to go and learn. But our land is rich in water. The name Tulu nadu is derived from land being too "tuluva" or rich in water. We need to take our land back to that state. How?
    Replenish ground water. Build "ingu-gundi" around bore-wells. Stop unscientific diversions of river sources. Preserve the river sources and reforest the western ghats. Harvest rain water. And STOP setting up heavy industries that require water. Our place is sensitive and too sacred to be exploited and polluted.

    As someone said above, the desalination is energy intensive and may be economically viable in rain starved places such as Chennai and Middle-East.

    Reverse Osmosis process for desalination of water is in existence since decades now. Cost of water generated through RO process is very high. Maintenance of desalination plant also involves high costs. Theft of water desalinated water from pipelines during peak demands is also another major problem.

    The yearly rainfall of Mangalore fluctuates roughly between 3000 mm to 5000 mm -same with Udupi . Agumbe is normally ranked in the first 5 of highest rainfall spots in the country,
    All the rain flow from the western ghats towards the sea. That is an enormous amount of rainwater.
    cannot store this water in lakes - artificial lakes can be done . This is not a rain deficient area by any measure. If our politicians can make SEZ of 3800 acres employing no mangalorean - why they cannot dig a lake for much needed water and also provide employment for many. For example- the US govt Big Thompson project, Colorado now serves 33 cities and has a capacity of 380 million tonnes of water. We can make smaller ones. the MSEZ is one hell of a mistake for our future - oil is anyways not going to used practically as primary fuel after 2030. Why waste valuable land . very short sighted business sense.

    After Chennai trip, Why don't the same team visit Dubai Abudhabi, to see the desalination plants over there. In UAE, Sea water, desalined, is the only source of fresh drinking water.... And absolutely there is NO disruption of water supply 24x7 , 365 days. In a country, Were you don't have rains, rivers, dams, falls & natural vegetation greenary. It is truly a blessing for the citizens & expatriates . Thanks & Salute to The Sheikh's of UAE.

    It's a totally wrong idea.. Mangalore unlike Chennai recieved abundant rainfall, which is enough for our needs.
    The sea salt generated due to this is detrimental to our fishing industry.
    Some time back there was a article in Daijiworld about some scientists suggesting ways to store the rainfall ,which is more than enough for our needs. We don't even need tumbay dam water. Even if they increase tumbay dam height by a few meters,it will again solve the issue.
    As usual lethargic planning by the MCC.

    Idea is good and should have done long back .yes ok . But MCC should not give this drinking purpose water to MR PL and MSEZ. must use for drinking purpose only. 932

    What an idea. Does DK need desalination plant? We should dredge Thume dam and increase the depth of the Dam or build another Dam in DK to store water. Cities like Mumbai don't even have desalination plant. Why we have this grave idea of desalination plant while Nidderam plan to send the water from DK to his hometown by Yettinahole project. Stop the Yettinahole project and we have to rule out desalination project for DK.

    If desalination is done in a large scale, due to increase in salinity there will be lots of ecological imbalances on the coast and land.
    It may be ok in desert cities but, Mangalore is still a fishing and agricultural district.

    Desalination of seawater is expensive, hence the available river water which is provided to various industries has to be reduced. These industries should build, operate and maintain the desalination plant and use that water for thier use. Already Thannirbavi area is identified for the desalination plant.

    You mean to say that we supply our river water to Bangalore and we drink desalinated water at higher cost. What a great idea. the politicians are fooling Magalorians.

    Some of the metal casing required for desalination is manufactured by a company in Baikampady itself for exporting to Australia. So, technology is not an issue, intent and planning is the need of the hour.
