As a result of continuing global population growth the production of wastewater is constantly increasing. Proper management of this wastewater (in a manner that is both economical and environmentally sensitive) is now a critical responsibility for regional authorities and contractors.

The first priority purpose of wastewater management is to minimize (or if possible, eliminate) the factors that pose an environmental pollution risk. It is also essential that wastewater from both domestic and industrial sources be treated. Waste water treatment plants subject wastewater to a number of physical, chemical and biological processes. These processes allow for the economically beneficial reclamation of usable water from some part of waste waters and the treatment of the remainder in an environmentally sensitive manner.
