In the past few years, every time the northwest wind blows up, there will be a smell in the sky above Yuwang Village. Yesterday, the residents of the natural village reported to the newspaper that there is a landscape pond in the center of the village. Thousands of tons of sewage from unknown sources flow in every day, and the stench is disgusting. However, the relevant staff of Guangyi Street said that the problem that has plagued the residents for many years will be solved within one month and solved one by one, and residents will also have a clean village.
Black River in the civilized village, affecting more than 120 households
Yesterday afternoon, step into Yuwang Village, Jiuqu Xiaoqiao, Liangting Yiyi. However, the smell in the air is unpleasant. In Yuwang, there is a pool of sewage, and the black lacquer is bright (see photo). Resident Shen Ayi said that she had a sore throat in the past two days. She had just gone to the hospital to hang water. Another resident, Master Shen, said that in the past two years, the respiratory tract disease in the village was high, and that children with pneumonia and bronchitis in the elderly have increased a lot.
When talking about Yuwang, at the door, the residents said that it was the source of water in the village decades ago. It is no problem to wash rice and wash vegetables. Later, I also worked on fish ponds. Surrounded by green trees and flying birds, the village is a provincial-level civilized natural village with good greening and environment. In the past few years, since the river has become stinky, the village’s camphor trees have no birds such as pulsatilla, and even flies and mosquitoes are not seen in the summer. The plants are watered with river water, and the evergreen at the entrance is also dead.
In recent years, sewage has continuously flowed into the village, and more than 120 households here have suffered. After the black water is full, they can only drain the dirty water to the clean river outside, forming a vicious circle. They speculated that the sewage was produced after the source was intercepted. It is likely that the pipeline in a nearby sewage treatment plant had a problem and returned to the lower-lying Yuwang Village. Recently, someone came to investigate the problem of the well, but no one told them why. Residents hope to build a lift pump to solve the problem of low terrain. So far, there is no saying.
The pipe network is intricate, and the competent department sends robots to investigate
In this regard, Shi Li, the relevant person in charge of the Guangyi Street City Management Office, said that in fact, he has been investigating the problem of Yuwang. Things are far from being as simple as the people think. Apart from Yuwang, the new mouth and the entrepreneurial river in the vicinity have black stinking phenomena, and the three rivers are connected. In the end, there is a problem with a river, or three problems. Still not clear. In fact, some time ago, the municipal drainage management department had closed the sewage mains in this area, and found the reasons through the underground pipeline robots. There is no news yet.
It is reported that the city, district and street departments are very concerned about the rivers and rivers here. They held a meeting in mid-September and asked for a thorough investigation of the reasons within one month. The most worrying authorities are the comprehensive problems, including rainwater, sewage, and old and new pipelines, which will require a longer period of governance. Once the cause is ascertained, the problem is solved. If it is only a single problem, then it will be solved quickly. If it is a more complicated technical problem, it may take several months.
They are also considering that they will design a lift pump for the residents to raise the water level and prevent the sewage from being poured. According to reports, they will also open a coordination meeting recently, inviting residents to come to the scene to inform the reasons and measures so that the residents can settle down.
