According to statistics, in 2019, 19,258 kilometers of pipelines were dredged, and more than 370 million yuan was invested in maintenance.

  In addition, the drainage management department also established a city-wide unified mobile pump truck intelligent dispatching platform by means of information technology, and tracked the emergency rescue process in real time through GPS positioning, video monitoring and other technologies, forming a three-level linkage of mobile pump truck dispatching at the city, district, and team levels. mechanism.

  Several early warnings issued this year, all of us were on duty to stand by. In two particularly heavy rains on June 15 and July 5, our commando team was also dispatched. At that time, we dispatched about 45 mobile pump trucks, and then forced disposal of about 3 places of accumulated water. Therefore, if there are several rains this year, through the efforts of our two-level water department in the urban area and our commando team, we can basically recover the accumulated water within two hours after the rain.
