Wastewater treatment is important for the protection of public health from waterborne disease, the protection of the natural environment, aquatic and wildlife that depend on it from the removal and prevention of contaminants that can accumulate in the environment and the protection of water sources for recreational use.
Wastewater is the ‘used’ water that goes down your drain when you flush your toilet, wash your dishes, take a bath and wash your clothes. The wastewater travels through underground pipes by gravity or through a wastewater pumping station to push the wastewater up a hill into the wastewater treatment facility where objects such as sticks, rocks, cans sand, gravel and other heavy materials are removed. Micro-organisms or ‘bugs’ are used to eat all the small bits of organic material. The wastewater is disinfected using ultra violet radiation and the biosolids are used in commercial applications such as soccer or baseball fields.
