[[File:Drinking water.jpg|thumb|[[Drinking water]]]] The '''water industry''' provides [[drinking water]]<ref>{{cite web | url=https://www.epa.gov/dwreginfo/information-about-public-water-systems | title=Information about Public Water Systems | date=21 September 2015 }}</ref> and [[wastewater]] services (including [[sewage treatment]]) to residential, commercial, and industrial sectors of [[the economy]]. Typically, [[public utility|public utilities]] operate [[water supply network]]s. The [[water]] industry does not include manufacturers and suppliers of [[bottled water]], which is part of the beverage production and belongs to the [[food sector]].

The water industry includes [[water engineering]], operations, water and wastewater plant construction, equipment supply and specialist water treatment chemicals, among others.

The water industry is at the service of other industries, e.g. of the food sector which produces beverages such as bottled water.<ref>{{cite web | url=https://www.cdc.gov/drinking-water/about/about-bottled-water-safety.html | title=About Bottled Water Safety |website=cdc.gov}}</ref>

==Organizational structure== There are a variety of organizational structures for the water industry, with countries usually having one dominant traditional structure, which usually changes only gradually over time.<ref>{{Cite web | url=https://ppp.worldbank.org/public-private-partnership/sites/default/files/2024-09/Workingnote9.pdf | title=Characteristics of well - performing public water utilities | website=ppp.worldbank.org}}</ref>

===Ownership of water infrastructure and operations=== * [[local government]] – the most usual structure worldwide, [[public utility]] * [[Central government|national government]] – in many developing countries, especially smaller ones * [[private ownership]] – more common in the developed world, see for example [[Water privatisation in England and Wales]] * [[co-operative]] ownership and related NGO structures, public utility

===Operations=== * local government operating the system through a municipal department, municipal company, or inter-municipal company * local government [[outsourcing|outsources]] operations to [[private sector]], i.e. [[private water operators]] * national government operations * private water operators own the system ** [[Build-Operate-Transfer|BOT]]s – private sector building parts of a water system (such as a [[wastewater treatment plant]]) and operating it for an agreed period before transferring to [[public sector]] ownership and operation. * cooperation and NGO operators

===Functions=== * Integrated water system ([[water supply]], [[sewerage]] (sanitation) system, and wastewater treatment) * Separation by function (e.g. [[Netherlands|Dutch]] system where sewerage run by city, water supply by municipal or [[Province|provincial]] companies, and water treatment by [[water boards]]), though some Water Supply Companies have [[Mergers and acquisitions|merged]] beyond municipal or provincial borders. * Other separation (e.g. [[Munich]], separated into three companies for bulk water supply, water and wastewater network operations, and retail)

==Standards== [[Water quality]] standards and environmental standards relating to wastewater are usually set by national bodies. * In England, the [[Drinking Water Inspectorate]] and the [[Environment Agency]]. * In the United States, drinking water standards for [[public water system]]s are set by the [[United States Environmental Protection Agency]] (EPA) pursuant to the [[Safe Drinking Water Act]].<ref>United States. Safe Drinking Water Act. {{USPL|93|523}}; {{USStat|88|1660}}; {{USC|42|300f}} ''et seq.'' Approved 1974-12-16.</ref> EPA issues [[water pollution]] control standards in conjunction with state environmental agencies, pursuant to the [[Clean Water Act]].<ref>United States. Federal Water Pollution Control Act Amendments of 1972. {{uspl|92|500}} Approved 1972-10-18.</ref> * For countries within the European Union, water-related [[European Union directive]]s are important for [[water resource]] management and environmental and water quality standards. Key directives include the [[Urban Waste Water Treatment Directive]] 1992 requiring most towns and cities to treat their wastewater to specified standards, and the [[Water Framework Directive]] 2000, which requires water resource plans based on river basins, including public participation based on [[Aarhus Convention]] principles.<ref>{{cite web |url=http://www.watertime.net/Docs/WP1/D7_Int_Context_final-revb.pdf |title=Archived copy |access-date=2004-12-29 |url-status=dead |archive-url=https://web.archive.org/web/20050408055840/http://www.watertime.net/Docs/WP1/D7_Int_Context_final-revb.pdf |archive-date=2005-04-08 }} Watertime - the international context.
