Global environmental resources are at a crisis point. Water shortages, land degradation, air pollution, and global warming continue to take a serious toll on our planet. New threats are emerging in the form of increasingly severe natural disasters, plant and insect species invasions as a result of global trade, global atmospheric transport of trace pollutants, and urbanization. And as a result, all available drinking water supplies are susceptible to devastation.

Project Case Study: A balancing act
Compared with the issues involved in process design, treatment plant hydraulics does not at first appear to be particularly difficult. The engineer needs to make certain that the weir in each successive process tank is lower than in the previous one, and that there is enough freeboard to prevent the tank from overflowing during high-flow conditions.
