|
Production
Capacity of Tap Water at the Year-end
refers to the actual comprehensive production capacity
of the waterworks administered by the urban construction department and those
owned by enterprises or institutions, taking the capacity of the main links, such
as water inflow, purification, conveyance
and outflow of the trunk pipelines into account. |
|
Length
of Water Supply Pipelines at the Year-end
refers to the total length of all the pipelines between
the water pumps and the users water meters. |
|
Annual
Volume of Water Supply refers to the total
volume of water supplied by the public water-works and those owned by
individual enterprises and institutions during the whole year, including both

consumption of households for daily life and the water consumption of public
welfare facilities, including the consumption of restaurants, hotels, hospitals, barber shops, public bathhouses,

|
Percentage
of Urban Population with Access to Tap Water refers to the ratio of
the urban non-agricultural population (excluding 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% |

|
Volume
of Gas Supply refers to the total
volume of gas sold to users in a year, including the volume for industrial
use, residential use and other uses. |
|
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% |
|
