Surface water, such as rivers, lakes, and streams, is replenished through the water cycle and is considered a renewable resource.

Desalination is the process of removing salt and other impurities from seawater to make it suitable for drinking, irrigation, and industrial use.

Drip irrigation is a water-efficient irrigation method that delivers water directly to the roots of plants, minimizing evaporation and reducing water usage.

Water resources management involves planning, developing, and implementing strategies to ensure the sustainable use of water resources, considering both human needs and environmental protection.

Industrial wastewater, agricultural runoff, and sewage discharge are all major sources of water pollution, contributing to contamination and degradation of water resources.

Water restoration refers to the process of restoring degraded water bodies, such as rivers, lakes, and wetlands, to their natural state or a more desirable condition.

Contour plowing, terracing, and mulching are all effective methods for preventing soil erosion and conserving water in agriculture by reducing runoff and promoting water infiltration.

Water equity refers to the fair and just distribution and use of water resources, considering the needs of all stakeholders and ensuring that everyone has access to clean and affordable water.

Installing low-flow faucets, taking shorter showers, and fixing leaky pipes are all effective methods for reducing water consumption in households.

Flood management involves a range of strategies and measures to reduce the risk of flooding and its impacts, including flood control, flood mitigation, and flood prevention.

Primary, secondary, and tertiary treatment are all common methods for treating wastewater to remove pollutants and contaminants before it is discharged into the environment.

Urban water management involves planning, developing, and implementing strategies to ensure the sustainable use of water resources in urban areas, considering both human needs and environmental protection.

Rainwater harvesting, rooftop rainwater harvesting, and cistern rainwater harvesting are all common methods for collecting and storing rainwater for use in agriculture, irrigation, and other purposes.

Rural water management involves planning, developing, and implementing strategies to ensure the sustainable use of water resources in rural areas, considering both human needs and environmental protection.

Water recycling, water reuse, and water conservation are all common methods for reducing water consumption in industries by minimizing water usage and maximizing water efficiency.
