Abstraction refers to the process where water is removed from a surface water or groundwater body, either permanently or temporarily (for example, water can be temporarily diverted and then returned elsewhere within the same system). Abstraction of water can be by a number of means such as pumping, piping, diverting water into a reservoir, or by sinking a borehole or well. In Northern Ireland we abstract water for public drinking water supply, industrial use, use in the food and drink industry, hydro-power generation, agricultural and agri-industry use, recreational use (such as golf courses) and for use in fisheries.
