"Thank you for your company's staff, comrade Xuan Jiren and Comrade Tang Hehui, for checking out the cause of pipeline leakage and repairing it in time. Thank you very much On the morning of August 25, the relevant person in charge of Ningbo fruit wholesale market Co., Ltd. sent a thank-you letter and a banner to the water supply company to thank the staff of Haishu water supply branch company for braved the high temperature test and facing the difficulties, so as to reduce the losses of the enterprise.

        It starts with a missed homework a week ago. During the epidemic period, in order to minimize the loss of enterprises, the water company launched a free professional "listening and leaking" service for enterprises. A week ago, the staff received a call for help from Ningbo fruit wholesale market Co., Ltd. the other party said that some users in the market reported that the water pressure was low, but the reason was not found. Therefore, it is urgent for the staff to come to help check. Haishu water supply branch immediately sent special personnel to the site to measure the pressure. It was found that the pressure of municipal pipeline around the market was normal, while the pressure of branch line in living area of administrative building was only 0.3KG.

In order to avoid the interference of environmental noise, the "listening leakage" operation is generally arranged in the quiet night. However, due to the particularity of fruit wholesale market, it is not allowed to stop water supply in the two time periods. The branch company and the market have agreed to close the normal pipeline in the plant area after the end of business at 2 p.m. to listen to the leakage of the pipeline with leakage points.

The fruit wholesale market, which was just completed in November last year, has a large area and a long pipeline. However, 186 mu of land and a full 5 km pipeline are only equipped with four valves, which greatly increases the difficulty of leak detection. In the middle of summer, Xuanji, the person in charge of Shiqi point of the branch company, and the leaker, Tang Hehui, in the heat of the summer, held the listening stick in his hand and wore a listening apparatus on his head. He picked up, put down and listened to him again and again. After nearly 2 hours of patient investigation, we finally heard the sound of special water flow on more than half of the pipeline, thus finding the crux of the problem. In the end, the problem was solved successfully for Ningbo fruit wholesale market. It is estimated that the leakage will recover nearly 120 tons / day of water loss for the fruit wholesale market.

In the face of thanks, xuanjiren and Tang Hehui showed modesty. "It is our duty to help residents and enterprises solve their problems. We will continue to do our job well and provide services as far as we can." They said.
