Does fraccing use a lot of water?

Fraccing does require water but far less than other industries such as agriculture or mining. Each hydraulic fracturing stage can use about 2.5 million litres (ML) of water – equivalent to the water in an Olympic size swimming pool. A well subjected to multiple fraccing stages could require between 7- 20 ML of water. Where multiple fracs are done much of the water can be reused, which reduces the overall requirement for water. Once a well is fracked it does not need to be repeated each year so this is a one-off water requirement unlike mining and agriculture.

It is important to note that the gas industry can use salty water or non-potable water for fraccing. The industry aims to use water from aquifers deep below the surface that it can access when drilling, rather than tapping the freshwater aquifers used by people and agriculture.
