• One in five global businesses affected by growing water shortages

    Experts say that by 2030 global water demand would outstrip supply by 40 percent; a new survey reveals that we do not have to wait that long: drought, shortages, flooding, and rising prices are already damaging companies in water-intensive industries

  • China to push sea water thousands of miles inland

    Chinese officials say they have a found a solution to uninhabitable deserts of Xinjiang in west china: pump raw sea water thousands of miles from the coast to fill Xinjiang’s dried-up salt lakes and desert basins in the hope that it will evaporate and encourage rainfall over drought-stricken areas of northern and northwestern China; the sea water would be carried through a pipeline made of plastic and fiberglass; water experts have condemned the proposal

  • Crumbling water infrastructure needs investment boost

    Water pipes and treatment systems in the United States are in a sorry state, but nearly two-thirds of voters and just over half of businesses would be willing to pay more for their water to ensure its quality and availability; the U.S. Environmental Protection Agency said that at the current rate of investment, the funding gap for water infrastructure could grow to as much as $224 billion by 2022

  • Rubber dam at Tempe Town Lake bursts, emptying lake overnight

    An inflatable rubber dam (called “bladder”) on Tempe’s Town Lake exploded, sending a wall of water into the Salt River bed; at least three-quarters of the about one billion gallons of water had drained overnight; those parts of the rubber dam which are wet have held up, but a plan to keep those parts of the dam which are above water failed, exposing the rubber to scorching sun that has damaged the material

  • Siemens's leak location and monitoring system reduces losses in drinking water supplies

    Precise knowledge of water losses is essential for operating and planning the maintenance of drinking water networks efficiently; Siemens’s new solution not only continuously checks for leaks, but also pinpoints them automatically; this is done by setting up district metering areas, in which the inflows and outflows of water are measured by ultrasonic flow meters

  • New sensor speeds water analysis

    New sensor creates a single procedure for in-situ monitoring of chlorinated hydrocarbons in water, obviating the need for laboratory-based technologies for the analysis of water contaminants, which are time consuming, labor intensive and expensive

  • Flooding risks along the Mississippi River underestimated by Army Corps of Engineers

    Scientists argue that the U.S. Army Corps of Engineers, in an effort to correct old data on water flows in the Mississippi, may have led to underestimates of the current risk of flooding on the Mississippi between the Ohio and Missouri Rivers, and to inadequate preparations by government agencies

  • World Bank report says 700 million people in 43 countries are under "water stress"

    More than 700 million people in 43 countries are under “water stress,” according to a new World Bank report; water-related projects in developing countries now account for more than a third of the World Bank’s projects

  • Growing demand for chemical plants to switch to IST

    A 2008 analysis estimated that seven of Clorox’s bleach plants placed a total of nearly ten million people in the United States at risk from chlorine gas release; Clorox announced last year that it was phasing out processing chlorine gas into sodium hypochlorite in its plants; trouble is, Clorox consumes only about 1 percent of the chlorine gas used each year in the United States, thus, the overall impact of Clorox’s positive move on the country’s risk is minimal

  • New survey shows many water, wastewater plants improve chemical security

    New study says 554 drinking water and wastewater plants in 47 states have replaced extremely hazardous substances with safer and more secure chemicals or processes; at least 2,600 additional water and wastewater facilities still use large amounts of chlorine gas

  • Aging infrastructure poses economic, security risks

    The World Bank says global infrastructure investment needs will be $35 trillion over the next twenty years; in the United States, a leading engineers group estimates that $2.2 trillion is needed over the next five years; the group gave U.S. critical infrastructure a D grade in 2009

  • New pipe-inspection technology detects leaks in aging pipes

    An aluminum ball slightly larger than a softball travel through hundreds of miles of water pipes and water mains; equipment inside the ball picks up the hissing sounds of any leaks, and the data are then wirelessly transmitted to a computer; after the pipe is drained, workers push the cart, which resembles a steel bike, through the pipe, and electromagnetic coils attached to a computer on the cart detect the location of the leak

  • Texas running out of water

    Texas’s population of about 24.3 million is expected to hit about 45.5 million by 2060, and the water supply can not come close to keeping pace; if the state were to experience major drought conditions with that many more people, officials estimate almost every Texan would be without sufficient water and there would be more than $90 billion in economic losses

  • Robot fish could monitor water quality

    Michigan State University researchers develop robots that use advanced materials to swim like fish to probe underwater environments; robotic fish — perhaps schools of them operating autonomously for months — could give researchers far more precise data on aquatic conditions, and the quality — and security — of the water supply
