Network Layout

April 2011

population density
Population Density

Calculation of total number of residents:

  • Normal Increase ( using equations)

Example:

- Total Area of Southern Remal = 2,754 Dounm

  • Total population in Southern Remal in 2002 = 17,500
  • Total population in Southern Remal in 2008 = 29,300

Hypothetical figures

Statistical Data

  • Population in Area under consideration:
population density1
Population Density
  • Saturationpopulation

Total Residential Area = 519,917 m2

Total number of population under saturation condition = 45,721 + 59,918 = 105,639

population density2
Population Density

Therefore,

Population density= Population / Total Area

= 99,435 / 641,000 = 0.155 person/m2

For your project use the following data;

  • Total Area of Southern Remal = 2,754 Dounm
  • Total population in Southern Remal in 2002 = 17,500 inh.
  • Total population in Southern Remal in 2008 = 29,300 inh.
  • Regular buildings,
  • # of stories = 5
  • apartment area = 150 m2
  • # of family members = 7
  • Population density = ??!!
allocation steps
Allocation steps:
  • Draw network layout for the target year and pinpoint junctions and pipelines.
  • Draw areas around the nodes in a way that cover the entire area under consideration.
  • Determine the water demand type of each junction using the land use map prepared and determine the areas that are served by each junction.
  • Calculate the number of population served by each junction (using the area and the density)
  • Calculate the demand of each junction by multiplying the population by the average consumption per capita.
  • Specify other types of demand and allocate them to the nearest nodes.
  • The demand of each junction should be multiplied by a coefficient accounts for UFW in the design year.
demand over nodes
Demand over nodes
  • Domestic Consumption in the design year = 150L\c\day.
  • School consumption = 10 L\pupil\day
  • Mosque consumption = 25 L\prayer\day
  • UFW =30 %

184*150*1.3
