改造未解积水难题 底楼依旧雨水倒灌

Core Viewpoint - Residents of Yitong Apartment in Xuhui District have expressed concerns about persistent waterlogging issues despite recent renovations under the "Three Olds to Three New" urban renewal plan, leading to dissatisfaction and health concerns due to mold growth in their homes [2][3]. Group 1: Background and Issues - Yitong Apartment, built nearly 30 years ago, suffers from severe infrastructure aging and is located in a low-lying area prone to rainwater backflow [2]. - Residents reported that after the completion of renovation work in July last year, which included the excavation and relaying of underground pipes, the waterlogging problem remained unresolved, causing confusion and disappointment among them [3]. Group 2: Renovation Details and Challenges - The project manager explained that the persistent waterlogging is primarily due to defects in the original underground pipes and a height difference between the internal and municipal drainage systems, which could not be fully rectified during the renovation [3]. - The road surface of the community was raised by approximately 50 centimeters to mitigate the issue, but problems with the drainage pipes in the residents' courtyards due to subsidence have led to blockages and damage, resulting in poor drainage [3]. Group 3: Future Plans and Community Response - To fundamentally resolve the waterlogging issue, it is necessary to reconfigure the drainage pipes within each ground-floor unit, which requires consent from the residents [3]. - The local street office reported that 19 out of 20 ground-floor residents have agreed to the necessary construction, and efforts will continue to communicate with residents to expedite the work, aiming for completion before the upcoming flood season [3].
