水電工程是現代社會中不可或缺的基礎設施之一，包括配水系統、配電系統、水源管理等多項功能。其中，水力發電是其中一個重要的角色，通過水力發電可以有效地產生清潔能源。然而，水力發電也帶來了環境上的一些問題，例如阻礙魚類洄游、改變水體生態等。因此，在進行水力發電工程時，需要考慮到對環境的影響。
另外，防洪工程也是水電工程中重要的一環。通過建立水壩和水文資源管理，可以有效地保護城市和農田不受洪水侵害。而污水處理則是環保的重要環節，通過有效地處理污水可以保護水資源不受污染，保護我們的水源安全。
綜合來看，水電工程對環境的影響是雙重的，一方面可以發揮清潔能源的作用，另一方面也需要注意對環境造成的損害，並進行相應的改善措施來保護環境。

Title: The Impact of Water and Electricity Engineering on the Environment
Article: Water and electricity engineering is one of the essential infrastructures in modern society, including functions such as water distribution systems, power distribution systems, and water resource management. Among them, hydropower generation plays an important role in producing clean energy efficiently. However, hydropower generation also brings about some environmental issues, such as obstructing fish migration and altering the aquatic ecosystem. Therefore, when carrying out hydropower projects, it is necessary to consider the impact on the environment.
In addition, flood control projects are also crucial components of water and electricity engineering. By constructing dams and managing water resources, cities and farmland can be effectively protected from flood damage. Furthermore, sewage treatment is an important environmental protection measure. By effectively treating sewage, water resources can be safeguarded from pollution, ensuring the security of our water sources.
Overall, the impact of water and electricity engineering on the environment is dual-fold. On one hand, it can contribute to clean energy production; on the other hand, the potential harm to the environment needs to be considered, and corresponding mitigation measures should be taken to protect the environment.
