Explanatory Notes on Main Statistical Indicators
Production Capacity of Water Supply refers to the designed comprehensive production capacity of water facilities, covering the 4 links of water collection, purification, conveyance, and outflow through trunk pipelines. Increase capacity through transformation and innovation projects are included as well. The capacity is determined mainly on the weakest of the above-mentioned 4 links.
Length of Water Supply Pipelines at the Year-end refers to the total length of all the pipelines between the water pumps and the user water meters, excluding pipelines newly installed but not used yet.
Annual Volume of Water Supply refers to the total volume of water supplied by water-works (units) during the reference period, including both the effective water supply and loss during the water supply.
Consumption of Water for Residential Use refers to the water consumption of households for daily life and the water consumption of public service facilities. The latter refers to water consumption for urban public services, including the consumption of government agencies and public institutions, military barracks, public facilities, wholesale and retail outlets, restaurants, hotels, and other units providing public services. Household water consumption refers to consumption of water for daily life of all households in the boundary of cities, including households of urban residents and farmers, and public water supply stations.
Percentage of Urban Population with Access to Tap Water refers to the ratio of the urban non-agricultural population (excluing temporary and mobile population) with access to tap water to the total urban non-agricultural population.The formula is:
Percentage of Population with Access to Tap Water =(Urban Non-agricultural Population with Access to Tap Water /Urban Non-agricultural Population)×100%
Production Capacity of Gasworks Gas refers to the actual comprehensive production capacity of the urban gasworks in gas generation, purification and delivery.
Length of Gas Pipelines refers to the total length of pipelines between the outlet of the compressor, blower or gas tank and the gas meters of users. excluding pipelines within gasworks, delivery stations, LPG storage stations, refilling stations, gas-mixing stations and supply stations.
Volume of Gas Supply refers to the total volume of gas sold to users in a year, including the volume sold and the volume lost.
Percentage of Urban Population with Access to Gas refers to the ratio of the urban non-agricultural population with access to gas (including gas, liquefied petroleum gas and natural gas) to the urban non-agricultural population(excluding temporary and mobile population). The formula is:
Percentage of Population with Access to Gas =(Urban Non-agricultural Population with Access to Gas/Urban Non-agricultural Population)×100%
Length of Paved Roads at the Year-end refers to the length of roads with a paved surface, and with a width of more than 3-5 meters, including high quality,medium quality and ordinary roads.
Urban Bridges refer to bridges over river courses, great separated junctions and overpasses in urban areas.Permanent bridges and semi-permanent bridges are included.Temporary bridges,railway bridges and culverts are excluded.
