The term “green water” is often used to refer to the natural water cycle in the environment. It refers to water in the form of precipitation (rain, snow, hail) and soil moisture. In the context of water use, various approaches and technologies can help optimize the use of green water:
- Rainwater use:
- Collecting and using rainwater is a sustainable way to use green water. Rainwater can be captured, stored and used for various purposes such as irrigation of agricultural fields, gardens and parks, flushing toilets or even for domestic applications after appropriate treatment.
- Soil management:
- Efficient soil management on roads and sidewalks helps to specifically drain rainwater from paved (concrete or asphalt) surfaces and collect it in storage systems. In this way, rainwater can be used for irrigation in a time-delayed and sustainable manner during periods of drought and made available again to the natural cycle at the right time.
- Water-saving irrigation systems:
- Technologies such as drip irrigation or high-efficiency sprinkler systems can optimize irrigation and reduce water consumption by delivering targeted water to plants.
The use of green water is an integral part of sustainable water management. It helps to improve resource efficiency, reduce dependence on conventional water sources and minimize environmental impact. It is important to promote these approaches in various sectors such as agriculture, urban planning and households to achieve sustainable and resource-efficient water management.
