4. Introduction
• The Society of Rose Valley near Adyala Road in Rawalpindi has a total
of 417 houses, one mosque, and one school.
• The design of the water scheme for this Society will be focused on
providing a reliable and sustainable water supply for the next 20 years.
• The water demand of the society will depend on the number of
households, size of the mosque and school, and estimated population
growth over the next two decades

5. Purpose:
•The purpose of this project is to design a water
distribution scheme for a society.
•The scheme will involve determining the
appropriate diameter and lengths of pipes.
•The design will also specify the size of the storage
tank needed to ensure an adequate supply of water.
•The ultimate goal of the project is to create an
effective and efficient system for delivering water
to the society in question.

6. EPANET:
•EPANET allows you to model water distribution
systems by defining the layout of pipes, tanks, and
nodes.
•Using EPANET, you can calculate the flow of
water through the pipes in your system, which can
help you identify areas of high demand.
•With EPANET, you can also calculate the velocity
of water in your pipes, which can help you identify
areas of high turbulence or low flow rates.
•Using EPANET we can model and optimize the
operation of your tanks.

8. Water Consumption:
•On average, the recommended water consumption
per capita is between 150-600 litres per day.
•According to WASA, the average water usage per
person is 200 litres per day.
•Water usage can vary by region and season, but
generally, the highest water usage occurs in the
morning and in the evening.

9. Factor Affecting water consumption:
•Climate and weather
•Population density
•Demographics (e.g., age, household size, income)
•Lifestyle and behavior
•Industry and agriculture
•Water availability and quality

10. Pipe Selection:
Main types of pipes commonly used in water
supply system
•Cast Iron Pipes
•Steel Pipes
•Asbestos Cement Pipes
•PVC Pipes
•Galvanized Iron Pipes

11. Pipe Selection:
Plastic Pipes (PVC)
•Life time is about 25 years
•Inexpensive, easy to install, Small Pumping
cost.
•Our Diameter are Varies between 100-350 mm

12. Water Distribution Design :
Total Number of Plot = 417
Mosque = 01
School = 01
•Design Period = 20 years

13. Population Forecasting:
• According to Growth Rate
Report Our population growth is
2.1%.
• We are designing a water scheme
for 20 Year.
• In Houses we assumed that
Average 200 litre per day is used.
• In mosque Average 15 litre and in
school 30 litre per day.
Years Population
Present (2023) 3336
Design (2043) 5004

14. Population Forecasting:
Site Average(litre/h) Maximum(litre/h) Peak (litre/h)
Houses 11.58 17.315 26.06
Mosque 0.00086 0.0130 0.019
School 0.0694 0.10416 0.15625

15. Population Forecasting:
We are Designing Our Water Supply for Peak Hour Consumption So:
For Houses : 26.0625 litres/hour
For Mosque : 0.0195 litres/hour
For School : 0.156 litres/hour

16. Nodal Demand:

17. Tank Design:
• Our Required Storage for supplying water
is 1000.8 cubic meter.
• But if we Build a Huge Structure its Too
much Expensive.
• So we Build on its 20% of total Storage
which is About 200.16 cubic meter.
Volume = Area* Height

22. EPANET Working

23. Conclusions:
• The use of EPANET led to an efficient and cost-effective design process that
resulted in a safe and reliable water supply for a housing society.
• The final water supply system design was able to deliver a consistent water
supply with sufficient pressure, flow, and low head loss, ensuring long-term
viability and customer satisfaction.
•EPANET optimization allowed for a more efficient system design, reducing the
overall project cost while meeting necessary fluid property requirements.
•Analysis results from EPANET showed that proposed pipe diameters, valve
settings, and pump specifications were suitable for the housing society's needs,
and any necessary adjustments were made to meet desired standards
