"Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water."

Surface water management: This type of management focuses on managing and conserving surface water resources such as rivers, lakes, and reservoirs.
Groundwater management: This type of management focuses on managing and conserving underground water resources, which can be accessed through wells and boreholes.
Urban water management: This type of management focuses on managing and conserving water resources in urban areas, including water supply, sewage treatment, and stormwater management.
Agricultural water management: This type of management focuses on managing and conserving water resources for agricultural purposes, including irrigation and crop management.
Industrial water management: This type of management focuses on managing and conserving water resources in industrial processes, including process cooling and wastewater treatment.
Water quality management: This type of management focuses on maintaining and improving water quality through monitoring and regulation of pollutants, water treatment processes, and ecological management.
Integrated water resources management: This type of management involves the coordination of all water resource management efforts across multiple sectors and stakeholders in a given region or watershed.
"97% of the water on Earth is salt water."
"Only three percent is fresh water."
"Slightly over two-thirds of this is frozen in glaciers and polar ice caps."
"Natural sources of fresh water include surface water, under river flow, groundwater, and frozen water."
"Artificial sources of fresh water can include treated wastewater (wastewater reuse) and desalinated seawater."
"Human uses of water resources include agricultural, industrial, household, recreational, and environmental activities."
"Water resources are under threat from water scarcity, water pollution, water conflict, and climate change."
"Fresh water is a renewable resource."
"Depletion occurring most prominently in Asia, South America, and North America."
"It is still unclear how much natural renewal balances this usage."
"Whether ecosystems are threatened is still unclear."
"Water resources are potentially useful for humans, for example as a source of drinking water supply or irrigation water."
"The remaining unfrozen freshwater is found mainly as groundwater."
"Only a small fraction [of unfrozen freshwater] present above ground or in the air."
"Treated wastewater (wastewater reuse) can be an artificial source of fresh water."
"It is still unclear how much natural renewal balances this usage, and whether ecosystems are threatened."
"Water resources can be used in households for various activities."
"Water resources are used in environmental activities."
"Water resources can be used in recreational activities."
