• San Diego completes major water pipeline project

    San Diego county has completed the San Vicente pipeline which will provide residents with fresh water in the event of a disruption; San Diego receives 90 percent of its water from distant sources thousands of miles away; the pipeline is part of a larger $1.5 billion project designed to provide San Diego county with water for up to six months if supplies are cut off by a major earthquake or natural disaster; these projects are becoming increasingly important as San Diego’s two primary sources of water, the Colorado River and the San Joaquin-Sacramento river delta begin to dry up

  • Manila reducing water supply in hopes of preventing another water crisis

    Philippine officials hope to divert another crippling water shortage this summer; officials decreased the water supply to Metro Manila and Central Luzon to slow usage and ensure water supplies will last until the rainy season; last year Manila faced a crippling water shortage that left millions with only a few hours of water a day and some villages entirely without water; officials resorted to cloud seeding to alleviate the water crisis with some success

  • Major breakthrough in desalination technology could be game changer

    A new desalination technique could be a significantly cheaper and more energy efficient alternative to aqueducts and dams; Oasys Water has developed ground breaking new membranes and draw solutions that generate fresh water faster, more efficiently, and at lower temperatures than existing desalination methods

  • Igloo-shaped Poo-Gloos eat sewage, clean water

    Inexpensive igloo-shaped, pollution-eating devices nicknamed Poo-Gloos can clean up sewage just as effectively as multimillion-dollar treatment facilities for towns outgrowing their waste-treatment lagoons, according to a new study

  • NSF funds new water sustainability project

    A 45 million grant from the National Science Foundation will allow University of Wisconsin-Madison researchers to turn a comprehensive lens on Madison’s water in all its forms — in the lakes, streets, faucets, ground, and atmosphere; the study will examine the complex links between the water system and factors such as land use, climate change, human activities, development, and ecosystems

  • Day of drinking recycled water nears

    Aussie researchers show that storm water collected from the aquifer into which urban water flows, after undergoing treatment, had dramatically lower levels of all hazards and contaminants; further supplemental treatment was needed to remove some hazards, though the process shows potential if improvements are made

  • Taiwan wants pigs potty-trained to curb pollution

    The Taiwanese government reports that experiments in potty-training pigs proved successful: a breeder of 10,000 pigs has established special pig “toilets” on the farm; the toilets were smeared with feces and urine to attract the pigs; within weeks, 95 percent of all pig waste was collected in the toilets, making the farm — as well as nearby rivers and fields — much cleaner; additional benefits: the cleaner farm helped reduce illness among the pigs and boosted their fertility by 20 percent

  • Securing the California Delta's levees before a major earthquake

    In the event of a major earthquake or flood and many levees failing simultaneously in California’s Sacramento-San Joaquin River Delta, as many as 515,000 residents and 520,000 acres of land would be in immediate danger; the long term effects could be even more widespread, as nearly 28 million residents depend on the Delta for water and irrigation; California lawmakers have increasingly turned their attention to securing the Sacramento-San Joaquin River Delta’s levees, but experts say that only little progress has been made

  • Florida City to inject treated sewage directly into underground aquifer

    Florida’s Biscayne Aquifer has begun to run low and communities are exploring alternative sources of water as well as methods to stretch existing sources; the city of Pembroke Pines plans to inject treated sewage water 60 to 200 feet below ground directly into underground aquifers rather than use the existing practice of pumping treated water into nearby wetlands, lakes, or fields, where it will slowly trickle down into the aquifer over several months or years

  • Arizona County to fingerprint employees with access to sensitive facilities

    Pima County, Arizona, is moving to fingerprint more employees who work with kids and populations who need special assistance, who deal with sensitive data, or who have access to critical infrastructure facilities such as wastewater treatment plants; “We don’t want guys with criminal backgrounds knowing how our radio system is constructed. The same with wastewater, which could be compromised,” John Moffatt, the county’s director of Strategic Technology Planning, said

  • Wastewater treatment lowers pathogen levels

    New analysis shows that pathogens levels in municipal water have dropped since the implementation of federal regulations on treating sewage in 1993; these treatment guidelines have proven to be extremely effective with 94 percent to 99 percent of all pathogens in biosolids eliminated after wastewater treatment

  • Seaweed: the new trend in water purification

    UConn biologist Charles Yarish is turning his enthusiasm for seaweed into a new system for cleaning up waterways; Yarish’s most recent endeavor will use seaweeds to clean up pollution from human sources, as well as waste from fish and even people; this approach, dubbed extractive aquaculture or bioextraction, promises to use the physiological properties of seaweeds and other organisms to clean up excess nutrients in polluted areas, making them healthier, more productive, and more economically viable

  • Freshwater sustainability challenges shared by Southwest and Southeast

    Twenty-five years ago, environmentalist Marc Reisner published Cadillac Desert: The American West and Its Disappearing Water, which predicted that water resources in the West would be unable to support the growing demand of cities, agriculture, new research offers new support for most of Reisner’s conclusions, using data and methods unavailable to him in 1986

  • Haiti's escalating crises come down to lack of clean water

    Haiti’s corrupt and indifferent government has done little to improve water and sanitation since a 12 January earthquake, making it likely that the cholera epidemic there will continue to spread; even before the quake, more than a third of Haitians lacked access to clean water; now, more than two-thirds of Haitians have no access to clean water; less than one-fifth of the population has access to a simple latrine or toilet

  • Nature's desalination: bacteria turn salty water fresh

    The growing global shortage of water has led to a growing interest in desalination to produce fresh water from seas and estuaries; conventional desalination plants, however, consume large amounts of energy; the solution: a bug-powered desalination cell that takes salt out of seawater
