The Hydraulic Approach Relevant to Circularity on Sustainable Water Catchment

We live in an era where it is quite difficult to track brisk growth in a variety of fields, such as engineering, artificial intelligence, space exploration, and industry. Although the rapid pace of advancements brings numerous advantages, there are some controversial thoughts against these advantages that arise from time to time. For instance, while the improvements in health infrastructure and ongoing medical achievements decrease the mortality levels even in less-developed countries, some circles on the other hand claim that due to the rapid increment of the population, the earth will not be able to survive much longer considering the boosting demand, since it does not have eternal natural resources. One of these scarce natural resources is water, and it is the most vital. Therefore, rational usage of water possesses continuous interest, and it is dependent on the concept of circularity and sustainability where drawing water from its natural cycle and efficient usage create its foundation. Additionally, even though sustainability and circularity are frequently seen as interchangeable concepts, not all circularity strategies are sustainable. For instance, the recycling of plastic bottles from bottled water contributes to the circular economy. However, environmental hazards such as pollution and emission during the production process, the use of plants on fertile land, and additional emissions from the shipping of plastic bottles to recycling facilities cause them to fall short of the sustainability concept. In this book chapter, a water catchment system that considers both circularity and sustainability is briefly explained by implementing an engineering perspective where the main principles of hydraulics and hydrology are taken into account as indisputable facts for drinking and irrigation purposes.
