Purified seawater to Mangaluru: Team to Chennai
Transforming sea water into fresh one - city team to visit Chennai
Quote:
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.

Rs. 871 crores means 100 MLD which can cater to 15 lakh people. Read
Jayalalithaa inaugurates Rs 871 cr desalination plant. Where are 15 lakh people in Mangaluru now?
For industries I think MRPL is already constructing a desalination plant of 50 MLD at Tannirbhavi which is enough for its future expansion and other industries planned in MSEZ. Even UPCL is mooting of a desalination plant. Mulki, Surathkal region can be supplied water from Shambhavi river & UPCL desalination plant. Harekala/Adyar dam is mooted for Ullal region. Many more dams are going to be constructed on Netravati for waterway project. These dams can release water to Mangaluru whever there is water shortage. I am sure that these dams are enough for feeding more than 20 lakh people till year 2050. Other dams along Mangaluru-Udupi belt can feed another 20 lakh people in this belt. Where is the need for extra desalination plants?
As far as Phalguni pollution, which is said to be because of Maravoor dam, only solution is to stop releasing all types of polluted water into it whether it is domestic or industrial.
Why did the government allocated Rs. 871 crores for desalination plant in a hurry and just Rs. 200 crores for Pashchima Vahini? The government has all the money for Yettinahole but no money for Pashchima Vahini. Even if you forget that the government is not even releasing money for land acquisition needed for Tumbe dam. Isn't the desalination plant for taking water to Yettinahole?
Here are some old news links.

Urban development minister R Roshan Baig told reporters on Tuesday that the city will be developed on 11,000 acres of abandoned mining land in Kolar Gold Fields (KGF), around 100 km from Bengaluru. To meet the drinking water needs of the city, desalination plants will be set up and sea water from Mangaluru will be brought to KGF through Yettinahole project pipelines.

Karnataka has also proposed four desalination plants at a cost of Rs 3,500 crore. These plants will be established in Udupi (Rs 735.30 crore), Mangaluru (Rs 2,533.61 crore), Saligrama (Rs 76.71 crore) and Kundapura ( Rs 154.42 crore) with the joint venture of Israel-based IDE and Vagas of Indian firm. This apart, six clusters, including Devenahalli, Doddaballapur, Harohalli, Dobbespet and Bidadi around Bengaluru will be developed as satellite towns.

Obviously this project is a part of the bigger project to take water through Yettinahole and not for Mangaluru. We don't need any projects around the parched city as I have already posted
here.
Do we need such desalination plants to spoil our sea & kill our marinelife by increasing salinity level of the sea? (Even IISc professor who suggested sea reservior said desalination plants are deadly for marinelife! Read earlier posts & news links.) It is pitty that our own selfish elected representatives for their political gains are compromising on our marine ecology. Let us unite and defeat these politicians in the coming election.
Yuva Brigade to clean river Nandini
Enough opportunities to process sea water
The team studied everything except where the process water is released back into the sea and what was effect on marine life. Without doing this they are giving a rosy picture! These parties want free Netravati water to be looted by the real estate mafia of the parched city and Tuluvas to pay for processing sea water! Look how they are telling Chennai is supplying desalinated water free of cost as if these politicians are going to pay from their personal pockets for desalinating sea water!
Now whoever wants to defeat this party the task has become easy. Fishing community is a decisive community in the elections! Just needs to create awareness among them on side effects of desalination plants on marine life and hence their livelihood.
Look at this report.
World's first desalination unit off Ennore coast
NIOT to build India’s first offshore desal plant near Chennai coast
Quote:
CHENNAI: Scientists from city-based National Institute of Ocean Technology (NIOT) will build the country's first offshore desalination plant about 40km from the Chennai coast with a capacity of about 10 million litres of water per day, said the director of the institute Satheesh C Shenoi.
A detailed project report for the plant, which is estimated to cost ?2,000 crore, has been submitted to the Centre for approval. Designed and built by NIOT scientists, the plant will come up off the shores of Ennore.
"Buiding the offshore plant involves a lot of engineering challenges, and the design is complex," said Shenoi, adding, "The plant can be scaled up for more capacity if required."
"The design for the offshore plant is ready. The project will be part of the deep ocean mission estimated to cost ?10,000 crore, which will be launched in March 2018," said M Rajeevan Nair, secretary, ministry of earth sciences on the sidelines of a one-day workshop on harnessing energy from the oceans.
'Existing plants dump concentrated brine in sea, harm marine life'
At present, Chennai has two desal plants each in Nemmili and Minjur with a combined capacity of 210 MLD and two more are planned with a total capacity of 550 MLD.
The plant will operate on the indigenously developed low temperature thermal desalination (LTTD), a lowcost and environment friendly technology to get potable water. The technology is based on the temperature difference in seawater at different depths.
To begin with, the plant will be diesel powered. But, eventually, scientists are hoping to operate the plant with electricity generated through Ocean Thermal Energy Conversion Technology (OTEC).
The technology will drastically cut down on the operating cost of the plant. OTEC, which generates electricity using the ocean's thermal gradient, will soon be tested in a desal plant to be built in Kavaratti, Lakshadweep. An OTEC test lab was also launched in NIOT on Monday to optimise the technology.
Scientists said the existing plants in Chennai operate on reverse osmosis tec hnology, which deposits highly concentrated brine in the sea, harming marine life.
The LTTD technology studied by NIOT works on the temperature difference between the surface water and the deep waters of the sea. The warmer surface water is evaporated at a low pressure and the resulting vapour is then condensed using the colder deep sea water to get purified water.
"We have to go 40 km from the coast to find the required depth for intake of deep sea cold water required for the process, since Chennai has shallow waters," Nair said.
Purnima Jalihal, head, energy and freshwater programme, said, "The capital for the proposed plant is high only because of the offshore component. The aim is to have the desal plant powered by OTEC, which will drastically bring down the cost. We also need not carry diesel from the shore to the plant to operate it."
NIOT will set up six more desal plants in Amini, Chetlet, Kadamath, Kalpeni, Kiltan and Andrott islands of Lakshadweep apart from the three that are currently operational.

Desalination by LTTD process
What it means is offshore desalination plant, with least effect on marine life, with 10 MLD capacity costs Rs. 2000 crores. So, 100 MLD will cost around Rs. 20,000 crores. Only adavantage Mangaluru has is sea is not shallow like Chennai so you need not go to 40 km from the coast to find the required depth for intake of deep sea cold water.
By the way, NITK should conduct thorough Risk Analysis on marine life even for proposed 50 MLD desalination plants of MRPL & UPCL and suggest hazard mitigation measures.

Mayor to write to CM for setting up seawater desalination plant in city
From the news it looks like this plant and the plant proposed by MRPL are one and the same. But 50 MLD is sufficient for industries. We don't want desalination plants of huge capacities. Where are they planning to release the brine water? Let them take it to the parched city through a small pipeline and supply to real estate mafia and their puppet politicians so that they can use it for cooking, bathing etc and their puppet politicians here also can use it. And, when will the mayor write to the CM to release money for the new Tumbe dam land acquisition?
And here is a good news from neighbouring district Chikkamagaluru. I had wished for such a research centre along with urban eco park at Pilikula.

Cauvery verdict Live: CM Siddaramaiah welcomes SC order increasing Karnataka’s share of water
Will they now at least cancel Yettinahole project?
I am interested in knowing whether following things can create a strong case against Yettinahole along with other reasons like water availability etc.
- Cauvery verdict.
- Usage of water available locally in the parched region for agriculture and industries while other parts of Karnataka are forced to import industrial & agricultural products from this region. For excample, DK has to import vegetables from this region. Hence wastage of energy & pollution from transportation.
- The region can easily divert some of lands like floriculture to solar plants hence not disturbing the economy of farmers.
- Over urbanization of the parched region neglecting the needs of urbanization/industrialization in other regions of Karnataka. Unnecessary migration of people from other parts of Karnataka to the parched region.
- Inequitable/non-inclusive growth of Karnataka with regional imbalances.
- Plan for desalination plants which will spoil marine life. (see reverse osmosis x LTTD evidence from Chennai above).
- Clubbing of Yettinahole with Mahadayi and giving a common judgement.
If Mangaluru MP, who is opposing Yettinahole, with his supporters files a fresh case against Yettinahole with all points keeping in over all economical & ecological sustainability, equitable growth of Karnataka then definitely people of DK can turn in his favour again. Otherwise we have to take refuge in Kumarswamy. I don't think it would be difficult for a man who prepared such a good 'medical tourism' plan to prepare a strong case against Yettinahole. Please remember that Supreme Court gave judgement in favour of Delhi BRTS after considering all ecological & economical consideration even though lower court judgements went against it. (Why BRTS failed in Delhi is a planning issue).
