Irrigation systems are necessary because the monsoons are unpredictable and in regions where cultivation completely depends on the rain, no rain can result in reduced yields or even total crop failure.

2. Domestic: Water required for household use is called domestic water. It is required for a variety of purposes such as drinking, preparing food, bathing, washing clothes and dishes watering plants, etc We generally get water in our homes in one of the following two ways It is either delivered by the municipal water distribution system, or we extract it from an underground source through a motor-driven tube well. In cities, municipal water treatment plants supply homes with treated water that matches drinking water standards. In rural areas, however, over 80% of the domestic water comes from underground sources.
