[China Instrument Network Instrumentation Documents] In order to give full play to the regulatory role of the ladder price mechanism, improve the efficiency of water resources utilization, and further standardize the measurement and collection of urban water users' water fees, improve the quality of water supply services and citizens' water-saving awareness, Lanzhou City Government Office, Gansu Province The Office issued the “Implementation Opinions on Water Supply Metering for Urban Residents in Lanzhou City†(referred to as “opinionsâ€).
Water supply meter readings for urban residents (one household per meter, household water meter, and household per household) refer to the installation of a trade water meter in a residential family home. The water meter digital display device is installed in the public part of the residence, which is convenient for water supply enterprises Measured and charged for water.
The implementation of urban residents' water supply meter reading to households should be based on the principle of “proactive, safe, standardized, and orderlyâ€, and the implementation of new, reconstructed, expanded residential and existing residential renovations should be implemented. Newly-built, rebuilt or expanded residences are strictly in accordance with national standards. Household metering meters are installed to facilitate outdoor meter reading; existing residential buildings are gradually implemented in accordance with the principle of “Easy to be difficult, users voluntarily, and the cost of renovation is assumed by the owner of the houseâ€. . To read meter-to-house conversions and new residential building water meters, we should actively implement intelligent management in accordance with advanced management concepts and technical solutions such as “Internet + smart waterâ€.
According to the “Opinionsâ€, the scope of implementation is: in urban areas of Lanzhou City, households with urban households who have newly built, reconstructed or expanded residential buildings and have not yet implemented a one-for-one settlement method. Dangerous buildings and the government have already included in the three-year plan for the implementation of the old city transformation and shanty town area reconstruction and the resident users who do not have the transformation conditions can temporarily implement the meter reading and household transformation, and the water fee still read the meter according to the general table. Water volume and current charges are enforced.
The "Opinions" pointed out that the newly-built, reconstructed or expanded residential buildings should be installed with separate household metering meters in accordance with the principles of "simultaneous design, simultaneous construction, and simultaneous acceptance" to facilitate outdoor reading and realization of meter reading. After the completion of the residential water supply project, the construction administrative department or its entrusted water supply industry management department or urban water supply company shall participate in the inspection and acceptance. Without acceptance or unqualified acceptance, the urban water supply enterprise shall not provide water. The administrative department of construction must strictly examine the design implementation of meter reading and exit when the preliminary design review, construction drawing filing, and start-up permit.
When designing a residential project, the design unit must design the water supply system according to the relevant design specifications. The water meter should actively implement intelligent management; the construction unit must construct the design based on the meter reading and exit design during construction. The supervision unit must supervise the construction in the project supervision, and the construction unit shall put the meter reading and exit design plan in place. The engineering quality supervision department must review the construction of meter reading and exit when the construction project is completed and accepted for record.
Construction projects that have already obtained the "Construction Permit" and have not yet installed water supply facilities or new construction, reconstruction, or expansion projects that have obtained the "Construction Permit" but have not yet commenced construction, must be installed and constructed in accordance with the requirements for meter reading and households. . Town water supply companies should ensure that the users who read the meter and reach the household are in place. After the acceptance of the project, the water supply contract is signed by the household and the rights and obligations of both parties are clearly defined.
According to the “Opinionsâ€, in order to facilitate the management requirements of urban water supply enterprises for the construction of outdoor courtyard pipe networks and reduce the leakage rate of pipelines, the construction of the outdoor courtyard pipe network of the water supply projects of residential construction projects shall be newly established, reconstructed and expanded, and the water meter shall be separated. The installation of the valve before and after the water meter of a separate household shall be entrusted by the construction unit to the construction unit with the corresponding qualification. The maintenance and replacement of water meters in the later period are the responsibility of the urban water supply company and bear the costs. When implementing the household water consumption measurement and transformation for existing residential buildings, according to the procedures of voluntary application, on-site inspection, project design, budgetary expenses, signing of contracts, relevant formalities, organization of construction, completion acceptance, etc. by users (property ownership units or property owners) The water supply company unified the implementation of transformation.
