Water industry officials often consider vortex valves a novel technology for outlet flow control within stormwater detention systems. That's why the majority of the 17,000+ vortex valve installations in Europe and North America are used in stormwater detention. These units, however, can be implemented in water management systems to reduce erosion, aerate discharge, and equalize flow, among other things.

Exploiting the biological complexity of natural systems to cope with the complexity of industrial waste streams is becoming a more attractive option because engineered treatment wetlands typically are mechanically simple and have low operation and maintenance costs.
Over the past five years, desalination has gained significant momentum in California. With more than 10 projects in various stages of environmental review, design, and construction, desalination is planned to provide 1,500 to 2,000 million liters per day (ml/d) of new fresh drinking water supplies for the state by 2015.
Many electric generating utilities that burn coal are engaged in retrofit projects using flue gas desulfurization (FGD) to meet emissions standards mandated by Phase 2 of the Clean Air Act.
