Water located beneath the ground surface An illustration showing groundwater in aquifers (in blue) (1, 5 and 6) below the water table (4), and three different wells (7, 8 and 9) dug to reach it. Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in ...
Sustainable yield: the maximum quantity of water calculated over long-term conditions in the basin, including any temporary excess that can be withdrawn over a year without an undesirable result; Sustainable groundwater management: the management and use of groundwater that can be maintained without causing an undesirable result.
In coastal regions, over pumping groundwater can increase saltwater intrusion which results in the contamination of groundwater water supply. [10] Sustainable use of groundwater is essential in water conservation. A fundamental component to water conservation strategy is communication and education outreach of different water programs. [11]
Use of groundwater, especially for irrigation, may also lower the water tables. Groundwater recharge is an important process for sustainable groundwater management, since the volume-rate abstracted from an aquifer in the long term should be less than or equal to the volume-rate that is recharged.
Self-supply is an important strategy - in combination with other approaches such as community-managed services - to achieve the United Nations Sustainable Development Goals, particularly for Goal number 6: "Ensure access to water and sanitation for all". [3]
Low-impact development (LID) is a term used in Canada and the United States to describe a land planning and engineering design approach to manage stormwater runoff as part of green infrastructure. LID emphasizes conservation and use of on-site natural features to protect water quality .
When more groundwater is pumped from wells than replenished, storage of water in the aquifer is being mined, and the use of that water is no longer sustainable. As levels fail, it becomes more difficult to extract water, and pumps will struggle to maintain the design flow rate, which may consume more energy per unit of water.
The amount of groundwater right is based on the size of the surface area where each landowner gets a corresponding amount of the available water. Once adjudicated, the maximum amount of the water right is set, but the right can be decreased if the total amount of available water decreases as is likely during a drought.
