Shenzhen will launch the household project of high-quality drinking water, with a future investment of 6billion

the implementation plan of the household project of high-quality drinking water in Shenzhen was announced and implemented by the municipal government bulletin today, and the long-awaited household project of high-quality drinking water in Shenzhen was officially launched. Benefiting from the project, more than 300, 000 households in more than 600 communities in Shenzhen will drink high-quality tap water within five years

"implementation of Shenzhen high quality drinking water household project 1. Ordinary protection scheme for rubber low temperature brittleness testing machine" was announced and implemented by the municipal government bulletin today, and the long-awaited Shenzhen high quality drinking water household project was officially launched. Benefiting from the project, more than 300, 000 households in more than 600 communities in Shenzhen will drink high-quality tap water within five years

according to the plan, Shenzhen will invest about 6billion yuan in the next few years, including a government subsidy of 1.5 billion yuan, to centrally update and transform the water supply pipes banned by the state in the city's residential areas, so that the water quality of users' tap water can meet the requirements of the "new national standard", and realize the entry of high-quality drinking water into households. After the transformation, the standard rate of high-quality drinking water for residential users is ≥ 95%, and the leakage rate of water supply pipes in the community is ≤ 5%. The "middle layer" of water supply is cancelled, and the water supply enterprise or its entrusted property service enterprise will charge the end users for meter reading

the quality of the produced water is good, and the quality of the tap water is not high.

the quality of the raw water and tap water in Shenzhen is generally good, but the guarantee rate of the tap water quality of some users is not high. Why? The reason is that before the state banned the use of galvanized steel pipes and gray cast iron pipes in 2000, such pipes were widely used in our city, prone to aging and corrosion, and difficult to meet the new national sanitary standard for drinking water. According to the survey, about 30% of the residential areas in the city that use or partially use galvanized steel pipes and gray cast iron pipes have obvious phenomena such as "yellow water" and impurity precipitation, and about 40% have a leakage rate of more than 10%, which not only brings potential harm to the safety of drinking water, but also causes a serious waste of water resources, which urgently needs to be transformed

due to historical reasons, the middle and high-rise residential areas in our city are charged by the meter reading of the "middle layer" of water supply. Part of the "middle tier" of water supply has nonstandard behaviors such as inadequate management, arbitrary collection of water charges, allocation of water losses, and collection of management fees from users by using water cut-off, which has become the focus of citizens' complaints, and is very likely to cause various contradictions and disputes, which is not conducive to social harmony and stability, and there is an urgent need for standardized management

over the years, citizens have generally called for the abolition of the "middle layer" of water supply. The key to solving the problem of meter reading to households by water supply enterprises is to speed up the implementation of the household project of high-quality drinking water when carrying out tensile tests in accordance with astmd638 and iso527, and solve the problems of water quality decline and high leakage caused by aging and corrosion of pipes

more than 600 residential areas will be reconstructed within five years, involving more than 300000 users

in order to completely solve the above problems, Shenzhen decided to start the household project of high-quality drinking water. Due to the large number and wide range of residential areas involved, the scheme proposes to implement the household project of high-quality drinking water in two stages. In the first stage, the energy used accounts for about 12% of the total energy consumption of the national economy, and the water supply facilities of users in residential quarters with obvious decline in the quality of their tap water and serious pipe leakage will be updated and reconstructed within a period of years; In the second stage, on the basis of the completion of the first stage, we will continue to expand the scope of household projects for high-quality drinking water

the residential areas to be reconstructed in the first stage include urban residential areas where the water quality of users' tap water is significantly reduced or the leakage of water supply pipes is high due to the use of unqualified pipes, and rural urbanization natural village areas in the original special zone (hereinafter referred to as natural village areas), accounting for about 30% of the total number of residential areas to be reconstructed in the city, involving more than 600 residential areas and more than 300000 users

the reconstruction of water supply facilities in the natural village outside the original special zone was implemented in accordance with the opinions on the construction investment and maintenance management of water supply pipes in Longgang District and Guangming New District of Bao'an District issued by the general office of the municipal government

in terms of transformation content, urban residential quarters include: general water meter, buried pipeline, water supply riser, user sub meter and user water supply pipeline behind the meter to the wall position of each household. The natural village community includes: the total water meter of the community, the buried pipeline, and the building water meter of the original villagers' self built buildings; Public water tanks (tanks) with water supply safety risks can be included in the reconstruction after evaluation

the government subsidy is about 1.5 billion, and each owner undertakes 200 yuan

it is estimated that the full implementation of the household project of high-quality drinking water in the city requires about 6 billion yuan of reconstruction funds, of which about 1.86 billion yuan is required for the implementation of the first stage of water supply facilities reconstruction. According to the plan, the reconstruction funds shall be raised in accordance with the principle of "government subsidies, and water supply enterprises and owners shall bear appropriate responsibilities". On the premise that all owners voluntarily transform and bear the agreed costs, the government will make a high proportion of the funds for the transformation of water supply facilities for users in residential areas. 3.1 spectral analysis - using the principle of spectroscopy to confirm the structure and chemical composition of materials

among them, urban residential areas: the residential owners of urban residential areas bear 200 yuan per household, and the owners of other houses bear the reconstruction cost according to the standard of 5 yuan/square meter or 300 yuan per user water meter. For the owners who enjoy the minimum living security treatment in our city, each district (New Area) can formulate policies to reduce or exempt them appropriately. With the consent of the owners' meeting, the reconstruction costs borne by the owners can be paid by the special property maintenance fund. After the reconstruction, the property right of the user's water supply facilities still belongs to the owner

natural village community: in view of the gradual urbanization of the roads in the natural village community and the transformation of water supply facilities to the building water meter, the users in the natural village community will not bear the transformation cost. The property right of the water supply facilities before the water meter of the building after the reconstruction is completed belongs to the government and is managed by the water supply enterprise

the total water meter, user water meter and supporting valve group in the community are provided by the water supply enterprise free of charge and installed by the construction unit. After the transformation, the property right of the water meter belongs to the water supply enterprise

the government subsidy fund needs about 1.5 billion yuan, which is invested in five years, and 50% is borne by the municipal and district governments respectively. The reconstruction funds of indoor water supply pipelines for users shall be borne by the owner and will not be included in this scheme. Integrated into comprehensive environmental improvement and urban renewal
