Between 1865 and 1920 Eugene Belgrand led the development of a large scale system for water supply and wastewater management. Between these years approximately 600 ...
The development of water treatment and filtration technologies went through many stages. The greatest level of change came in the 19th century as the growth of cities forced the development of new methods for distributing and treating water and the problems of water contamination became more pronounced.
Water filters have been used throughout history to improve the safety and aesthetics of water intended to be used for drinking or bathing. In modern times, they are also widely used in industry and commerce. The history of water filtration is closely linked with the broader history of improvements in public health. [1]
The centralized drinking water supply infrastructure in the United States consists of dams and reservoirs, well fields, pumping stations, aqueducts for the transport of large quantities of water over long distances, water treatment plants, reservoirs in the water distribution system (including water towers), and 1.8 million miles of ...
Atmospheric water generation is a new technology that can provide high quality drinking water by extracting water from the air by cooling the air and thus condensing water vapour. Rainwater harvesting or fog collection which collect water from the atmosphere can be used especially in areas with significant dry seasons and in areas which ...
The amount of fluoride added to a water supply varies not only by city and county but also by the individual water system supplying a given neighborhood. For many years, the federal recommendation ...

The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.
The rapid sand filter or rapid gravity filter is a type of filter used in water purification and is commonly used in municipal drinking water facilities as part of a multiple-stage treatment system. [1] These systems are complex and expensive to operate and maintain, and therefore less suitable for small communities and developing nations.
