• 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
