Waste Water Treatment Plant is a process to convert waste water – which is water no longer needed or suitable for its most recent use – into an effluent that can be either returned to the water cycle with minimal issues or reused. The latter is called water reclamation and implies avoidance of disposal by use of treated waste water effluent for various purposes. Treatment means removing impurities from water being treated; and some methods of treatment are applicable to both water and waste water. The physical infrastructure used for waste water treatment is called a “waste water treatment plant” (WWTP).
Waste Water Treatment Plant
The treatment of waste water belongs to the overarching field of Public Works – Environmental, with the management of human waste, solid waste, sewage treatment, storm water (drainage) management, and water treatment. By-products from waste water treatment plants, such as screenings, grit and sewage sludge may also be treated in a waste water treatment plant. If the waste water is predominantly from municipal sources (households and small industries) it is called sewage and its treatment is called sewage treatment.
The process from rainwater to tap water is more complex than you might imagine. The water that comes out of your tap has been through various processes that clean and change its original properties, physically and chemically.
Do you know what the processes are? The aim of this Engineering Kit is to introduce you to a number of Water Treatment Plant (WTP) processes that are commonly used in getting clean potable water to your household. Civil Engineers design, monitor and maintain water treatment plants and water supplies. Civil engineers are vital in the treatment and delivery of water to your household. Water supply is the water that comes into your property from the water mains via a service pipe and through the water meter into your home. Water is a limited resource. Less than one per cent of the earth’s water is fresh and can be utilized for human consumption. The amount of this water will never increase as the water cycle is a closed system.
Drinking water is water that is safe for humans to drink and to use for domestic purposes, such as cooking, washing up, bathing and showering. Water Treatment Plants have many processes and steps before a household turns on their tap and receives water. From the dam to the tap there is a vigorous process with many steps that are all essential in assuring high quality water for drinking.
