Earthtalk: Can desalination saves us from freshwater woes? The protagonist of Samuel Taylor Coleridge’s 1798 lyrical ballad The Rime of the Ancient Mariner proclaims “Water water everywhere / nor any drop to drink” as his ship drifts through Antarctic seas with no land (or freshwater) in sight and the crew slowly dying of thirst. An allegory for our modern age if there ever was one, we’re all in the same boat today given the fact that seawater covers 70 percent of the Earth’s surface while freshwater becomes scarcer in the face of overpopulation […] Earthtalk: Can desalination saves us from freshwater woes?DME GmbH2019-08-26T01:48:48+02:00

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 […] Niti working out proposal to set up desalination plants along coastline to tide over water crisis – IndiaDME GmbH2019-08-22T00:28:46+02:00
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. (LINK).

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 […] Singapore pours $7.2bn into underground sewage superhighway – SingaporeDME GmbH2019-08-17T18:54:06+02:00
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 […] Expert cautions developing countries over water desalination plants – San DiegoDME GmbH2019-08-16T11:45:40+02:00
