Definitions & Technical notes:

Water supply industry: It corresponds to ISIC division 36 (the International Standard Industrial Classification of All Economic Activities, ISIC Rev. 4) The water collection treatment and supply industry includes water collection, treatment and distribution activities for domestic and industrial needs. This includes abstraction of water for distribution from various sources (mainly surface water and groundwater), natural water (CPC 1800) treatment for distribution and the actual distribution of natural water (CPC 1800) by pipes, channels and others means. The operation of irrigation canals is also included; however the provision of irrigation services through sprinklers, and similar agricultural support services, is not included.
(Remark: In earlier versions of the UNSD/UNEP Questionnaires on Environment Statistics, the term Public Water Supply was used instead of Water Supply Industry)

Net freshwater delivered by water supply industry refers to gross freshwater delivered by public water supply industry minus freshwater losses during transport.

Net freshwater delivered by water supply industry per capita is calculated by dividing the net freshwater delivered by water supply industry by the total population of the country.

Percent of population supplied by water supply industry is the percentage of the resident population connected to the water supply.

Net freshwater delivered by water supply industry per capita supplied is calculated by dividing the net freshwater delivered by water supply industry by the number of people connected to the water supply industry.

Data Quality:

Data on net freshwater delivered by water supply industry is usually collected from municipalities. Data on percent of population supplied by water supply industry can be obtained through municipalities or through household surveys. Household surveys usually give more accurate results, since they do not rely on sometimes incomplete information about or held by municipalities.
Data on amounts of water supplied can significantly vary between countries depending on the extent to which water supply industry delivers water to industries, businesses, agriculture and power station in addition to households. Care must be taken when comparing data between countries.
