India takes to solar-powered desalination – India

India has joined the nations using PV to produce drinking water after a 10,000-liters-per-day solar-powered desalination plant was set up at the Vivekananda Memorial in Kanyakumari, Tamil Nadu.

The plant was developed by a team from the Indian Institute of Technology-Madras (IIT-M) and the Ministry of Earth Sciences funded the Rs1.22 crore ($175,000) experimental project.

Chennai to get 500 million cubic feet of water from Mettur – Chennai – India

The State government has decided to provide the city with an extra supply of around 500 mcft of Cauvery water, a portion of which was released from the Mettur dam on Sunday night, and is expected to reach Veeranam tank in Cuddalore in 10-12 days.

With just less than 700 mcft of water left in all four reservoirs of the city, supply of Cauvery water comes at a crucial time as the city is slipping into a severe drought situation.

IIT-Madras sets up India’s 1st solar-powered desalination plant – India

CHENNAI: The technology behind desalination plants may appear simple extract seawater, remove salt, make freshwater but operating such plant is a power intensive and can also pollute the environment through toxic brine (salts) effluents.

After it was realized that the solution to tackling water scarcity lay in seawater and the Sun, a team has now set up the country’s first solar-powered desalination plant, with a capacity to generate 10,000 litres of freshwater a day, on 120sqm near Vivekananda Memorial at Kanyakumari.

Wastewater Recycling and Reuse in India – India

India’s growth story has been impressive so far with industry and service sectors being the growth drivers. Along with industrial and population growth, the demand for water also increases.

Unpredictable rainfall patterns because of climate change, depleting water resources because of extreme groundwater extraction, contamination of available surface/groundwater resources due to discharge of untreated sewage, and/or industry effluents have had an impact on water quantity and quality.

Per capita water availability is expected to reach 1,140 cubic meters by […]

LTTD-based desalination plant to come up at Thoothukudi? – India

With thermal power plants being the largest industrial users of water and exceedingly contributing to water-stress, Chennai-based National Institute of Ocean Technology (NIOT) has come out with a novel concept of using coolant water discharge from power plants to produce fresh water.

Thoothukudi Thermal Power Station will be the first in the country to have an in-house 2 MLD (million litres per day) desalination plant based on Low Temperature Thermal Desalination (LTTD) technology.

This assumes significance as the Thoothukudi power […]

MRPL’s seawater desalination plant gets CRZ clearance – Mangaluru

The Expert Appraisal Committee for Projects related to Coastal Regulation Zone (CRZ) of the Union Ministry of Environment, Forest and Climate Change has recommended CRZ clearance to the State’s first reverse osmosis-based seawater desalination plant proposed by Mangalore Refinery and Petrochemicals Ltd. (MRPL).

Headed by Deepak Arun Apte, the committee in its 207th meeting on January 25 said that the clearance was subject to MRPL ensuring temporary structures installed for laying pipelines for the 70 million litre per day (MLD)-capacity plant are removed within one month of […]

Desalination plants causing harm to environment: UN – New Delhi

The fast-rising number of desalination plants worldwide – now almost 16,000, with capacity concentrated in the Middle East and North Africa – quench a growing thirst for freshwater but create a salty dilemma as well – how to deal with all the chemical – laden leftover brine

In a UN – backed study made public on Monday, experts estimate the freshwater output capacity of desalination plants over 95 million cubic meters per day – comparable to 40 percent of the high season flow over Niagara Falls.

Recycling water Chennai’s only hope – Chennai

CHENNAI: Chennai’s water woes are legendary. That 2019 too marks another year of crisis is sadly little cause for surprise.

The Northeast Monsoon failed in 2018. There is only enough water in the city’s reservoirs to meet drinking water needs for the next five months.

With erratic rainfall patterns becoming the new normal and Chennai’s groundwater having been exploited to dangerous depths, is there a long-term solution to the almost perennial crisis?

Gwadar desalination plant enquiry sent to NAB for investigation – Pakistan

Legislators in the upper house of the Parliament on Thursday expressed serious reservations over mismanagement in a two-million gallon per day (MGD) water desalination plant in Gwadar and demanded a probe to fix responsibility for the plant’s condition as early as possible.

An enquiry report had found massive instances of mismanagement in the project. The report pointed fingers towards a tankers mafia claiming that it did not want to see the water supply project successful because it would disturb their businesses.
