Water treatment is any process that makes water more acceptable for a specific end-use.

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.

Water treatment removes contaminants and undesirable components, or reduces their concentration so that the water becomes fit for its desired end-use.

Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water.

The goal is to produce water fit for a specific purpose.

Most water is disinfected for human consumption (drinking water), but water purification may also be designed for a variety of other purposes, including fulfilling the requirements of medical, pharmacological, chemical and industrial applications.

The methods used include physical processes such as filtration, sedimentation, and distillation; biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light.

A water filter removes impurities from water by means of a fine physical barrier, a chemical process or a biological process.

Filters cleanse water to different extents for purposes such as providing agricultural irrigation, accessible drinking water, public and private aquaria, and the safe use of ponds and swimming pools.

A water supply system or water supply network is a system of engineered hydrologic and hydraulic components which provide water supply.

A water supply system typically includes:

Fresh water is naturally occurring water on Earth's surface in ice sheets, ice caps, glaciers, icebergs, bogs, ponds, lakes, rivers and streams, and underground as groundwater in aquifers and underground streams.

Fresh water is generally characterized by having low concentrations of dissolved salts and other total dissolved solids.

The term specifically excludes seawater and brackish water although it does include mineral-rich waters such as chalybeate springs.

The term "sweet water" (from Spanish "agua dulce") has been used to describe fresh water in contrast to salt water.

The term fresh water does not have the same meaning as potable water.

Much of the surface fresh water and ground water is unsuitable for drinking without some form of purification because of the presence of chemical or biological contaminants.
