Take measures to alleviate water use in some communities with insufficient water pressure.

Some multi-storey residential buildings in urban areas have suffered from insufficient water pressure for more than a month, which has troubled many citizens. To this end, the municipal water supply and drainage group quickly organized personnel to investigate the reasons and took effective measures to alleviate the water problems in some communities. At the same time, some communities with insufficient water pressure in our city hope to install their own pressurizing equipment to supply water for the communities, but the reporter learned through interviews that it is not feasible from the technical level of water safety or the policy level of capital use. Therefore, to completely solve this problem, we must increase the construction and transformation of water supply network.

Residents: Domestic water can be basically guaranteed.

"The water is getting bigger and bigger these two days, so you can take a bath." Ms. Xin Wang, who told reporters about the difficulty in using water in the Canal Community, called the reporter again yesterday, saying that the tap water at home is getting bigger and bigger, and the solar water heater can also take water. Although the water supply will be stopped occasionally, the basic living water supply is guaranteed.

In addition, the reporter also got good news from Mr. Wu, who lives in the family. "The water will still be cut off during the peak period, but the water will come after a while, and the water flow is ok." Mr. Wu said that a while ago, water was cut off for a long time and he was not at home during the day. Sometimes you can't get water when you come. Because water was always cut off, he moved to his parents' house for a while. In recent days, the water supply situation has improved slightly, and he moved back home.

Recently, reporters have received feedback from residents of some communities with insufficient water supply, saying that the water pressure on the fifth and sixth floors of the communities where they live rebounded and the water shortage problem was alleviated. Although the water consumption has not returned to the daily level, compared with the days of the previous month, the daily water consumption of residents for drinking, washing and cooking is now guaranteed. Water supply and drainage group: emergency measures have achieved initial results

"In the past month, water supply in some urban communities was insufficient. We have arranged three working groups to visit and investigate communities with insufficient water supply pressure and analyze the reasons. " The relevant person in charge of the Municipal Water Supply and Drainage Group said: There are four reasons for stopping water supply in some multi-storey residential quarters in the urban area this year.

First, the temperature rose rapidly this summer, and the peak of urban water consumption was nearly 20 days earlier than in previous years. The maximum daily water consumption has reached nearly 6.5438+0.3 million cubic meters, an increase of more than 20,000 cubic meters year-on-year, reaching a record high. Second, the old pipe network in the urban area caused explosion pressure and repaired the affected area. Third, the pace of urban construction in the western region has been accelerated, and the demand for water has increased. However, the long distance and small diameter of the water supply pipeline west of Chaoyang Road in the original planning layout directly affected the water pressure in some areas. Fourth, the unreasonable use of secondary pressurization equipment in high-rise buildings affects the regional water supply pressure, and the unreasonable selection and use of some pressurization equipment, especially the non-negative pressure equipment that directly pumps water from the water supply pipeline, has a particularly prominent impact on the pressure of the pipe network. The increase of secondary pressurized pumping capacity at the peak of water consumption directly leads to insufficient water supply pressure on the fifth and sixth floors of multi-storey houses in the surrounding areas.

In view of various reasons that may lead to insufficient water pressure, the water supply and drainage group has also taken countermeasures. They carried out regional pressure measurement and valve inspection on the old pipe network equipment, replaced seven valves in the urban area, and investigated the hidden dangers of leakage. At the same time, strengthen pipeline inspection to prevent pipeline damage caused by improper operation of valves by construction and irrelevant personnel. Under the condition of ensuring the overall operation safety of the pipe network, the factory pressure of the water plant should be appropriately increased to adjust the water supply pressure of the regional pipe network. At present, the factory pressure is close to the upper limit.

"In line with the reconstruction plan of huanghe road, we have completed the reconstruction task of the water supply line of the main plant in the Yellow River section, and reconstructed more than one old pipeline 10, with a total area of 2,000 meters, and accelerated the reconstruction of the pipe network." The person in charge said that several measures went hand in hand, and the situation of insufficient water pressure in some parts of the city was alleviated. Technician:

It is not possible to install a booster pump. "Recently, we communicated with the technical staff of the technical department of the water supply company and wanted to install a booster pump for the community." Manager Bai of Jiayuan Community told the reporter that although the water consumption in the community has improved, it has not completely solved the problem of insufficient water supply.

Manager Bai's idea has become the knowledge of some residential property companies with insufficient water supply to solve this problem. However, the relevant person in charge of the municipal water supply and drainage group said that it is not feasible to install booster pumps from the technical level or the policy level.

"Installing a booster pump will definitely have an impact on the water use in other surrounding areas, which may cause more water problems. In addition, it depends on the specific situation of the pipeline near the community, because some old pipelines may not be able to withstand the pressure of the booster pump, and the booster pump can't be installed if it wants to. " The relevant person in charge of the Municipal Water Supply and Drainage Group said that it is illegal to install a booster pump on a six-story multi-storey building, and there are many water safety hazards.

Installing a booster pump requires not only a field survey of water supply pipelines and local conditions, but also a large sum of money, and where this part of the money comes from is also a problem.

"Although the maintenance funds belong to the owners to solve the problems in the community, it is not allowed to install the booster pump with maintenance funds." According to the work of the Property Department of the Municipal Housing Construction Bureau, Article 25 of the Measures for the Administration of Maintenance Funds stipulates that part of the expenses shall not be charged from the special housing maintenance funds, including the maintenance expenses of water supply, power supply, gas supply, heating, communication, cable TV and other pipelines and facilities.

It is unrealistic to rely on residents to raise a lot of money to buy booster pumps. The water supply department still needs to do a lot of investigation and calculation on whether booster pumps can be installed in residential areas, and it will not be solved soon. Therefore, in order to fundamentally solve the water supply problem, we must strengthen the construction of new urban pipe network and the transformation of old pipe network, bring the secondary pressurized water supply into unified management as soon as possible, and further improve the pressurized facilities.
