Water industry
▶ The water industry provides drinking water and wastewater services (including sewage treatment) to households and industry.
▶ The modern water industry operates sophisticated and costly water and wastewater networks and sewage treatment plants, and
typically consumes 1-2% of GDP. It is generally a natural monopoly, and as a result is usually run as a public service by a
public utility which is owned by local or national government. In some countries, notably France, the UK and the Czech Republic,
the water industry is regulated but services are largely operated by private companies with exclusive rights for a limited period
and a well-defined geographical space.

| (Potable/drinking water treatment) |
|
Industry of intake, deliver and purification from lake or river(nature). It includes physical and chemical processes to remove physical, chemical and biological contaminants. Its objective is to produce clean water for suppling. |
|
(Wastewater/sewage treatment) |
|
Industry of removing contaminants from wastewater and sewage. It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants. Its objective is to produce a waste stream (or treated effluent) and a solid waste or sludge suitable for discharge or reuse back into the environment. |
