    thanks SAUGA . I registered @ new scientist + copy pasted article into word doc for future access

    more from article (regarding engineering solutions)

    < "The ultimate risk is that we do not see what's happening, so we cannot take action at the right place at the right time," Ghandehari says. "It's like not getting a check-up, and then all of a sudden having a heart attack." >

    < Engineers are already developing new diagnostic tools. Small robots can explore gas lines. Electric lines can be probed with an electromagnetic pulse, the speed and shape of which changes if it encounters any defects. And water pipes can be inspected using ultrasound. >

    < But for new pipes, Ghandehari suggests a much lower-tech solution: put utility lines in tunnels that human workers can walk through. "The rule of thumb is that you need to have access for inspection," he says. "Cities of the future should consider how to deal with providing access to the urban lifeline." >

    •  London Uk partially on to walk-on solutions (2+ / 0-)

      As part of the preparations for the recent London Olympics there was a massive investment in wider infrastructure in east London. This included putting things like power lines underground.

      The new utilities are in walk-through tunnels allowing inspection.

      Violence is the last refuge of the incompetent.

        ...that won't explode when under water.
