  • GE Leakwise Application Notes: Oil Detection in Hydro-Electric Power Plants

    Leakwise* Oil Detection in Water Collection Sump Under Turbines Water carries oil leakage from turbine bearings and other leaking sources into a large sump, which is built under the turbines. In most plants, pumps installed at the bottom of the sump discharge the water directly to the river.  A Leakwise lD-221 Floating Oil Detector is installed in a perforated 6” stilling well. The ...

  • Solving waste oil management and removal problems in power generating plants

    If your plant is like most, it is doing a good job of preventing oily water waste and waste oils from escaping into the environment. But at what cost? As labor resources dwindle, operating and maintaining drainage systems, oil separators, and sometimes inadequate oil removal equipment is expensive. Paying higher than needed costs for waste oil disposal, filtration and water treatment due to these ...

  • How better weather forecasting can help stretch water supplies

    Reservoir managers look to storm predictions to make smarter choices about dam operations Last year, New York City faced an unusual situation. An epic winter in the city’s Delaware River watershed brought heavy snow and very little rain. Stubborn cold meant there was no snowmelt to refill water-supply reservoirs, even as the city’s 9.5 million residents were draining them dry. A ...

  • Planning for the Unthinkable Risk Assessment and Emergency Response Planning for Catastrophic Events District of Columbia Water and Sewer Authority (DC WASA)

    ABSTRACTManager’s decision capabilities can be improved through a better understanding of a system’s inter-dependability. Communication and planning during non-emergency periods enable managers and engineers to review the impacts that would be expected during several scenarios, and what system improvements could be made to minimize those impacts. The plan that DC WASA developed helped managers ...
