### Lecture 5

Network Layout

April 2011

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:

• Saturationpopulation

Total Residential Area = 519,917 m2

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

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 = ??!!

• 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.

• 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

• Network layout.

• Area around nodes.

• Demand over nodes.
