fracturing,. ,Water supply, . Hydraulic ,fracturing, requires access to volumes of ,water, that are generally not large compared to other uses, such as irrigation, and large industrial and town ,water supply,. Typically, between 0.1 and 10 ML of ,water, is required for hydraulic ,fracturing, of a coal seam gas well, but 1 ML per ,fracturing, event is common.
