Niti working out proposal to set up desalination plants along coastline to tide over water crisis – India

The Niti Aayog is working on a proposal to set up a string of floating desalination plants in marine waters along the country’s over 7,500-km coastline, with a view to tide over the water crisis being faced in major urban centres of India.

Recently, several parts of the country, especially Chennai, faced severe water crisis, owing to poor storage in various reservoirs following deficit rainfall.

“The Niti Aayog is working on linking desalination of sea waters with the Sagarmala project,” a top government official told PTI on the condition of anonymity.

California Focus: Desalination loses more urgency in hyper-wet winter – California

Desalination began to lose its urgency among Californians and their public officials two years ago, after the drought-busting winter of 2016-17, when heavy rain and snow ended dry conditions in most of the state.

The idea of drawing potable water from the sea became even less of a priority this year, when an autumn of record-level fires gave way to one of the state’s wettest winters on record.

L&T sees growth in desalination projects – India

L&T’s water and effluent treatment business is eyeing a slew of desalination and water treatment projects worth $1 billion in the country.

The business, which is undertaken by L&T Construction in partnership with UAE-based Tecton Engineering and Construction, is seeing significant demand mostly from coastal regions.

“Coastal regions in India from the South, the East and the North-West are looking at desalination plants as an option to reduce the stress on municipal corporations,” S Rajavel, Head of the Water and Effluent Treatment business, L&T, told BusinessLine. He, however, did not specify the time-frame of these expected projects.

Freddie Mercury, David Bowie invented desalination process: Telangana textbook

A Telangana Class IX SSC textbook, according to a Times of India report by Nirupa Vatyam, has cited late rockstars Freddie Mercury and David Bowie as “scientists”, crediting them with “removing salt from seawater using a semi-permeable membrane through a process called desalination”.

The goof-up in the biology textbook appeared in the “Did You Know” section, according to the report. Thomas Jefferson is considered the inventor of the earliest forms of desalination.

Singapore pours $7.2bn into underground sewage superhighway – Singapore

The government of Singapore is spending $10 billion Singapore dollars ($7.2 billion)tocomplete an underground sewer system in the city-state.

The pipeline, dubbed the “underground superhighway,” is 3- 6 meters in diameter and buried 35- 55 meters underground. It will collect wastewater from households and factories and transport it to treatment plants, which will be used mainly for industrial and air-con cooling purposes.

“For us in Singapore, used water is a source of good water. We do not waste a drop of it,” saidNg Joo Hee, chief executive of the Public Utilities Board.

Expert cautions developing countries over water desalination plants – San Diego

A water expert is cautioning developing countries over the establishment of water desalination plants as a means of providing potable water to the populace.

Jeremy Crutchfield of the San Diego County Water Authority in the USA says desalination (the treatment of seawater through the removal of salt) is a very expensive process because of the high cost of operation including the vast amount of electricity needed to operate such plants.

Water companies would usually establish treatment plants along rivers and streams which are not salty so the processing requires fewer inputs.

Saudi Arabia launches $826m water projects – Saudi Arabia

Saudi Arabia has launched water developments in Makkah and across other holy sites worth over $826.6 million.

Projects include setting up a pipeline for carrying desalinated water from the desalination plant in Al-Shuaibah to Makkah and the holy sites at a total cost exceeding $233m (SAR875m), and the second phase of Al-Shuaibah Desalination Plant with a capacity of 250,000 cubic meters per day at a cost of over $313m (SAR1.175bn).

Other water services projects include water networks, connections to homes, strategic reservoirs and sanitary drainage networks and connections at a cost of over $160m (SAR600m) in several districts of Makkah and the holy sites.

New Agreement Will Advance Desalination Supply System In Chile – Chile

An agreement between UQ’s Sustainable Minerals Institute Centre of Excellence in Chile (SMI-ICE-Chile) and TRENDS Industrial paves the way for collaboration on an integrated multi-user desalination supply system in Chile’s Atacama region.

Chile, and the Atacama Region in particular, is in a severe drought and continued industrial development, especially by the mining industry, will depend on a sustainable water supply.

This is Singapore’s plan to avoid running out of water – Singapore

This is Singapore’s plan to avoid running out of water

Every day after his morning run, Adam Reutens-Tan washes under a half-full camping shower hooked on the ceiling of his bathroom.

The modified shower, which uses just four litres of water, is one of several ways the Reutens-Tans family conserve water as part of a countrywide push to cut Singapore’s daily consumption by 8% by 2030.

The nation currently uses 141 litres per person each day – about enough for two typical eight-minute U.S. showers, according to Harvard University statistics.

Sydney’s desalination plant set to expand as drought continues – Australia

The New South Wales government has begun preliminary planning to boost output at Sydney’s desalination plant, in a bid to secure the city’s water supply as dam levels continue to drop.

The Kurnell plant, which can currently supply drinking water for up to 1.5 million people in Sydney, returned to operation in January for the second time since 2012.
