Here are some synonyms for "drainage" in English:
1. Sewerage
- Meaning: Sewerage refers to the system of sewers that carry away waste water and sewage from buildings and other areas. For example, "The city is investing a lot of money in improving its sewerage infrastructure to prevent flooding and water pollution."
- Usage difference: While "drainage" has a broader sense and can refer to the natural or artificial removal of water in general, "sewerage" is more specifically focused on the disposal of waste - laden water through an underground network of pipes.
2. Drainage system
- Meaning: A collection of drains, pipes, and other structures designed to remove water. For instance, "The new housing development has an efficient drainage system to handle heavy rainfalls."
- Usage difference: This is a more comprehensive term than "drainage" alone. "Drainage" can be a general concept of water removal, but "drainage system" emphasizes the physical components and their organization that make up the means of draining water.
3. Water removal
- Meaning: It simply means the act of taking away water. For example, "Proper water removal is essential in basements to prevent mold growth."
- Usage difference: It's a more basic and general way of expressing the idea of getting rid of water. "Drainage" often implies a more established or engineered way of water removal, while "water removal" can cover any means, from using a bucket to more complex pumping systems.
4. Dewatering
- Meaning: The process of removing water from soil, a structure, or a material. For example, "Dewatering is a crucial step in construction sites located near water bodies."
- Usage difference: "Dewatering" is usually used in technical or industrial contexts, such as construction or mining. It focuses on the process of extracting water, whereas "drainage" can refer to the overall system or the natural flow of water out of an area.
