  • A Dutch first in the polder - Water Board Zuiderzeeland measures flow rates to achieve sustainability

    The Dutch province of Flevoland lies metres below sea-level. That’s why rain and seepage need to be removed from the polder, some 6 metres up. And that’s the reason Flevoland is drained continuously by seven huge pumping stations. The quantity of energy involved in this is as great as the energy consumption of 4,000 households. Water Board Zuiderzeeland has launched the ‘Energy ...

  • Iterative LP water system optimal operation including headloss, leakage, total head and source cost

    Linear water balance optimal operation models are common with relative short solution times but suffer from a lack of certainty whether the given solution is at all hydraulically feasible. Introducing hydraulic headloss, water leakage and changing pump energy consumption, effect the resulting system optimal operation but also create a non-linear problem due to the convex relation between flow, ...
