Andhra Pradesh’s desalination plants look paradoxical – India

The news that Andhra Pradesh is planning to go in for desalination plants in the State with Israeli technology comes as a surprise in fact. Desalination plants are a solution to the water problem no doubt, but for Andhra Pradesh to mull the same is ironical.

Andhra Pradesh is not exactly a water deficit State by any yardstick. Its problem is the run-off waters. Nearly 3,000 tmcft water flows waste into the sea every year through the Godavari and the Krishna rivers.

Good monsoons and cyclones are also a feature that should ensure water surplus if the State goes in for careful planning.

Woes watered-down – India

CHENNAI: On Tuesday, CE reported that due to the lack of water supply in the tenements at Perumbakkam Resettlement Colony, a group of people including 50 women from the Colony stood outside the Tamil Nadu Slum Clearance Board (TNSCB), staging a protest, demanding basic needs including water. Soon, in response to the call of the residents, the TNSCB officials resumed water supply and told CE that they will ensure no further problem arises.

In line with the perennial water woes at the Resettlement Colony, the Slum Board officials have decided to soon increase the quantum of water being supplied to the tenements. In four months’ time, by when the construction of 14 more blocks will get over, the Slum Board officials said they will request the Metro Water Board to provide more water according to the needs.

Chennai takes new strides towards water security – India

After undergoing one of the worst water crisis in its history, Chennai bounced back to come up with milestone projects that could make the city water secure in the long run.

With the four major reservoirs that supply drinking water to Chennai going bone dry and deficit rains during 2018, the city’s water supply was reduced 525 million litres a day (mld). It was one of the first Indian cities to run dry early this year.

As taps stopped flowing and water became a premier commodity, residents looked deeper into the ground and sunk borewells up to a depth of 600 feet. In June, the average groundwater table in the city declined by a staggering nine metres.

Foundation stone laid for 100 MLD desalination plant – India

Gujarat Chief Minister Vijay Rupani laid the foundation stone for the country’s first desalination plant having a capacity of 100 MLD at Dahej Petroleum, Chemicals and Petrochemicals Investment Region (PCPIR) in Bharuch district on 30 November 2019.

The plant is estimated to entail an investment of Rs 881 crore. The water from the plant will be supplied to industries in Dahej. Eight desalination plants will come up in Gujarat where sea water will be converted and made fit for industries, agriculture and drinking purpose. The plant will be operational in the next 30 months.

The quality of water supplied from the plant will be like the one of Narmada river. Under the present state water supply scheme, industries in Dahej get 454 MLD water daily.The quality of water supplied from the plant will be like the one of Narmada river.

Work on a third desalination plant in Nemmeli to begin by October-end – Asia

Work on constructing a third desalination plant at Nemmeli, along East Coast Road, is set to begin by the month-end.

The new plant, with a capacity to treat 150 million litres of sea water a day (mld), will come up on a 10.5-acre space on the same premises as the earlier 100-mld plant.

Metrowater officials said materials had been sought for the work to commence. The new plant too will employ the reverse osmosis process. But it will have additional components in the pre-treatment process such as dissolved air flotation and ultra filtration, to keep out sea algae and other particles in seawater from hindering the production process.

India’s ‘grave’ water crisis a result of misallocation, mispricing, mismanagement – India

According to NITI (of Government of India) Report (June 2018), India is now entering in to the phase of “acute water scarcity” and if no adequate measures are taken, then the water demand would exceed water supply by the year 2030.

Also, the ground water resources in many cities including Delhi, Chennai, Bengaluru would get exhausted. Water stress is rapidly turning in to water crisis. Water availability on the earth remains the same as it was 5000 years ago when mankind population was just 5 million as against present population of 7700 million.

However, “there is enough water for everyone’s need but not enough for anyone’s greed”, as pointed out by Gandhiji who was also not in favour of “putting too much burden on the resources (including water) provided to us by nature”.
