- Abstract:
- The role of source sponge facilities in the control of total runoff and runoff pollution has been widely recognized. However, its effect on the improvement of drainage standards of built blocks remains to be investigated. In response to the issues of substandard rainwater pipe network and high risk of regional waterlogging at a wastewater treatment plant (WWTP) in Shanghai, the InfoWorks ICM software and the sustainable drainage system (SUDS)/low impact development (LID) functional modules were employed to simulate and analyze the impact and effectiveness of sponge facilities on upgrading drainage systems in both the front and tailwater areas of the WWTP. The surface waterlogging area ratio of the two areas was reduced from 4.18% and 13.11% to 0 after the implementation of sponge transformation under the design rainfall with 3-year return period, achieving the targeted system upgrade. Additionally, there was a significant reduction in peak runoff by 35.97% and 21.53%, as well as a total runoff reduction rate of 28.91% and 25.89%, respectively. These results demonstrated that the sponge facility effectively contributed to improving drainage standards of built blocks.
