Surface Reservoirs
Surface reservoirs are one of the most common types of reservoirs for water. These are typically large bodies of water, such as lakes and rivers, that are used to store and manage water resources. Surface reservoirs can be created naturally or artificially, depending on the needs of the area. Natural reservoirs tend to provide a large amount of storage capacity for a large area, while artificial reservoirs tend to be smaller and more localized in their management. Not only do surface reservoirs act as storage for water, but they also provide recreational activities and wildlife habitats.
Groundwater Reservoirs
Groundwater reservoirs are another type of reservoir for water. These are typically located underground and can range from shallow aquifers to deep groundwater systems. Groundwater is often used for drinking water supply and agricultural irrigation purposes due to its cleanliness and availability. Groundwater is also important in maintaining aquatic ecosystems, as it helps keep streams and rivers flowing during dry periods when surface water resources may not be available.
Artificial Reservoirs
Artificial reservoirs are constructed by humans in order to store or regulate the flow of water. These can range from small ponds that serve a specific need or purpose, such as providing drinking water or recreational opportunities, to large-scale impoundments that regulate entire river systems. Artificial reservoirs can also be used to generate hydroelectric power or provide flood protection by storing excess runoff during wet periods.
Underground Storage Reservoirs
Underground storage reservoirs are another type of reservoir for water that is located below ground level. These types of systems usually involve pumps or wells which draw out groundwater from beneath the surface and then store it in an underground chamber for future use. Underground storage systems usually require specialized equipment for maintenance, but they can provide a great source of clean drinking water with minimal environmental impact.
