The Punjab province …Change in land water storage. Ground water, surface water, soil moisture, snow, and ice. 2002 - 2016Irrigation makes up more than 70% of water withdrawal from groundwater and surface water sources, and from that, it is estimated that 43% comes solely from groundwater. Groundwater is used when land becomes dry and there is a larger water demand, but when enough rainfall meets the agricultural needs, less groundwater is extracted.Water in aquifers is brought to the surface naturally through a spring or can be discharged into lakes and streams. Groundwater can also be extracted through a well drilled into the aquifer. A well is a pipe in the ground that fills with groundwater. This water can be brought to the surface by a pump.Surface water and groundwater are both important sources for community water supply needs. Groundwater is a common source for single homes and small towns, and rivers and lakes are the usual sources for large cities.
