The Xindingpitou (New Dingpitou) Main Drainage is an agricultural drainage system located upstream of the Jiudingpitou (Old Dingpitou) Main Drainage, covering a catchment area of 883 hectares. To meet irrigation needs, two sluice gates have been installed, irrigating an area of 81.25 hectares. However, the second sluice gate, completed 53 years ago, along with its structural facilities, has become a bottleneck for flood discharge in the upstream river section due to aging. This has led to flooding issues during heavy rains and typhoons, causing multiple embankment breaches. After repeated petitions from local residents and representatives, an improvement project was undertaken to enhance the existing drainage channels and sluice gates, ensuring smooth drainage and protecting public property. This project was awarded the Excellence Award in the 2019 Outstanding Agricultural Construction Engineering Awards.
