水電工程是城市建設中不可或缺的重要一環。高壓配電系統、自來水管網以及污水處理設施都是水電工程的重要組成部分。高壓配電系統確保城市能夠順利供電，讓居民生活更加便利舒適。自來水管網則是城市居民生活必不可少的基礎設施，能夠確保供應清潔安全的飲用水。而污水處理設施則負責將城市廢水處理過濾，保護環境和居民健康。
Water and electricity engineering are essential components of urban construction. High-voltage power distribution systems, water supply networks, and sewage treatment facilities are all important parts of water and electricity engineering. High-voltage power distribution systems ensure smooth power supply to cities, making residents' lives more convenient and comfortable. Water supply networks are indispensable infrastructure for city residents, ensuring the supply of clean and safe drinking water. Sewage treatment facilities are responsible for treating and filtering city wastewater to protect the environment and residents' health.
