Following land subsidence, the drainage system is as good as non-existent because of the new low-lying topography that results. When it rains, the place becomes a "water world," putting the people's life and property at risk and lowering their quality of life. And it has become a long-term problem and concern for the government.
地層下陷後，由於地勢低漥，排水系統形同虛設，一下雨就成為水鄉澤國，使民眾生命財產缺乏保障、生活品質低落，更是政府長期的痛。
