Translation and Meaning of: 排水 - haisui

The term 「排水」 (haisui) is a Japanese expression that refers to the process or action of draining water, often in contexts such as drainage systems. The word is composed of two kanji: 「排」 (hai) which means "to expel" or "to repel," and 「水」 (sui) which means "water." When combined, they evoke the idea of expelling or removing water from a specific space, such as in sanitation systems or rainwater runoff. The importance of efficient drainage is vital in modern urban areas, where poor water management can lead to flooding or infrastructure degradation.

Historically, water management and its drainage have been a crucial issue in human societies, including Japanese society. Since ancient times, the Japanese have developed techniques and structures to deal with excess water, especially due to the humid and rain-prone climate in most of the archipelago. Drainage systems were vital for agriculture, particularly for rice cultivation, which relies on careful water management. Over the years, these agricultural practices have also influenced urbanization and the development of Japanese cities, bringing an ever-increasing need for efficient 「排水」 systems.

Importance of an Adequate 「排水」 System

• Flood prevention in urban areas.
• Maintenance of infrastructure and prolongation of its useful life.
• Preservation of the environment, preventing soil erosion.
• Public health promotion by eliminating standing water.

In the modern context, 「排水」 encompasses not only rainwater drainage systems but also those for liquid waste from domestic and industrial uses. The complexity of these systems requires careful engineering and serious regulation to ensure that • the disposal of effluents does not harm local ecosystems and human health. Thus, the word 「排水」 is not limited to a simple concept of excess water but includes an essential infrastructure for sustainable urban life.
