Guidelines to Make Water Harvesting Helpful and Meaningful for Groundwater Management
Efforts are being made using different methods to harvest rainwater and artificially recharge groundwater in various parts of the world. But if the quality of water to be harvested is not good, and such structures are not maintained properly, water quality may be a problem and harvesting can provide very limited good‐quality water. Declining water tables can also cause seepage to groundwater from surface water sources polluted with sewage, agricultural fertilizers, and industrial by‐products. In addition, indirect recharge enhancement may work for shallow groundwater, but deeper systems require sophisticated injection and alternative sources of high‐quality water. Moreover, only some shallow aquifers get recharge from surface water and the deeper aquifers cannot be recharged from surface water sources. Since existing policies are not strict on limiting water use, in many areas increasing groundwater use and pollution generation have crossed sustainable limits. To make water harvesting meaningful for groundwater management, individuals/society need to be encouraged to reduce water consumption and manage water demand, by communicating ideas, norms, and innovative methods for water conservation.
