黄岩区永宁江地处浙东南沿海,常年雨量充沛(年平均降雨量约1600mm),属亚热带季风气候地区,每年受台风影响次数多,范围大,强降雨,常使河口建有大型水闸的永宁江因海潮水顶托,无法将永宁江的洪涝水及时排入椒江流入东海,为解决永宁江洪涝水的出路问题,建设强排工程(泵站)已成为可能。
Yongning River in Huangyan District is located in the southeastern coast of Zhejiang Province with abundant annual rainfall (average annual rainfall is about 1600mm). It belongs to the subtropical monsoon climate area. Due to the large number of typhoons and heavy rainfalls, the Yongning River Due to the sea tide support, it is not possible to flood the flood waters of the Yongning River into the East China Sea in time and it is possible to build a strong drainage project (pumping station) in order to solve the outlet problem of flood water in the Yongning River.
