电力储存与配电 / Power Storage & Distribution

变电站在电力系统中起分配和调节作用。将发电站的电力通过变电站分配到各区域。变电站的数量和位置影响供电可靠性。电力储存设施（Power Storage）可以将多余的电力储存起来，在负荷高峰时释放。储能设施可以平衡电力供需，减少浪费。在城市规划时，预留变电站位置和电力线通道是重要的前瞻性设计。

Transformer Stations play a distribution and regulation role in the power system. Power from generation stations is distributed through substations to each district. Substation数量和 location affect power supply reliability. Power Storage facilities store excess electricity and release it during peak loads. Storage balances power supply and demand, reducing waste. When planning cities, reserving substation locations and power line corridors is important forward-looking design.

供水与排水 / Water & Sewage

取水设施 / Water Intake

抽水站从河流、湖泊或海洋取水。取水点必须选择水质良好的水源。注意不要让排水管出口靠近取水口，否则会导致水污染。抽水站的容量有限，随着城市扩张需要增加抽水站数量或升级设施。抽取的地下水需要考虑含水层的再生能力，不过度开采。在水资源丰富的地区，供水压力较小；在干旱地区，水资源管理尤为重要。

Water Pumping Stations draw water from rivers, lakes, or the ocean. Intake points must选择水质良好的 water sources. Note: do not let drainage outlets靠近 water intake points, as this causes water pollution. Pumping station capacity is limited; as the city expands, increase station数量 or upgrade facilities. Extracted groundwater must consider aquifer regeneration capacity; avoid over-extraction. In water-rich areas, water supply pressure is lower; in arid regions, water resource management is particularly important.

污水处理 / Wastewater Treatment

水管网络布局 / Water Pipe Network Layout

供水管和排水管通常平行铺设，覆盖所有已开发的城区。管网需要连接成环状网络，避免末端死角导致水压不足。管道铺设成本按长度计算，因此在规划时应避免不必要的绕行。管道老化后维护成本会增加，定期的管道更新可以降低长期维护费用。在建设新区时提前铺设管道可以避免后期破路施工。

Water supply and sewage pipes are typically laid in parallel, covering all developed urban areas. The pipe network should form a looped system to avoid dead ends causing insufficient water pressure. Pipe laying costs are calculated by length, so avoid unnecessary detours in planning. Pipe aging increases maintenance costs; regular pipe renewal reduces long-term maintenance expenses. Laying pipes提前 when developing new areas avoids later road-breaking construction.

供暖系统 / Heating System

供暖系统是寒冷气候地图上的关键公用事业。锅炉房（Boiler Station）产生热水，通过供暖管道输送到建筑。集中供暖比每栋建筑独立供暖更高效节能。供暖管道需要覆盖所有建筑，管道布局与水管类似。供暖系统的燃料类型影响运营成本和排放水平。在温暖气候的地图上供暖需求较低，可以延后建设或简化配置。供暖系统的效率受建筑保温等级影响，升级建筑保温可以减少供暖需求。

Heating systems are critical utilities on cold climate maps. Boiler Stations generate hot water, delivered to buildings via heating pipes. Central heating is more efficient than individual building heating. Heating pipes must cover all buildings, with layout similar to water pipes.
