This notice was posted on the Kunming Water Authority's official WeChat account. Pardon the quick and dirty translation job:

"Water outages caused by pipe replacements will affect neighborhoods along Xuefu Lu (from Jiaochang Zhong Lu to Huangtupo), the Hongshan area, Jinding area, along Dianmian Dadao, along Puji Lu, the Gaoxin area and the northwest part of Kunming. Water outages may be complete in some areas, while others will see a lowering of pressure."

The scheduled stoppage time is Nov 28 at 10pm until Nov 30 at midnight.

停水范围：学府路（教场中路至黄土坡）段沿线、虹山片区、金鼎山片区、滇缅大道沿线、普吉路沿线、高新区片区、昆明市西北片区等片区水压下降。停水受影响的片区内直供水（即无二次加压）的小区，高峰用水时段会出现压力低或无水的情况。
