Abstract

The hereby study is a tentative to improve/modify the water network of a

selected area and have for purpose the study of a whole system as part of water

networks engineering.

The purpose of such study is to become familiar with the different possible

systems and networks as well as their application to real life situations. Our aim

in this project is to study/design a new network and its facility for Fanar town(El Meten) as an area of study in order to fulfill the requirements of this project.

EPAnet software will be used later on in order to design the network system for

this town.

For the time being we are requested to investigate the current area to get all the

required data required to estimate the demand and inquire about the actual

facility, its use and the possible improvements we can bring to such existing

system.

Introduction

In a first time we tried investigating the Zekrit area specifically for its industry

presence as well as the known scarcity of water resources and wastewater

network. Unfortunately due to the lack of serviceability of the municipality and

the lack of cooperation from their part forced us to move our focus on a different

area. Fanar was our best bet since the mayor of the area is very reachable and

available to all our questions.

The town already has a fairly working infrastructure system for the area but

definitely needs improvement and upgrades to serve efficiently this area.

Especially since it is a major zone of educational facilities housing several

schools and colleges.

Fanar is located over 2.3 Km2 d has an altitude of 250m above the sea level.

Contacting officials, visual inspection and research has collected the following

data.

Data Collection

First, we would like to thank the mayor Mr. Ghoussoub for sharing with us useful

information in order to achieve this report. The following are some technical,

environmental, geographical and demographic data about the area of study

arranged in no particular order.

-Location:

Fanar is located 8km from Beirut District,

-Demographic:

Fanar has an estimated population of 39000 capita distributed in around 12000

houses over an area of 2.3 km2. Fanar early expansion began in the late 80s and

still expanding exponentially till today.

-Academicals facilities:

Fanar holds 7 schools with 5000 students, 4 Lebanese universities

-Hospitals and other Facilities:

Fanar hosts no hospitals for the moment, but we find important to mention that

in 2020 a project for building a hospital will be very likely feasible due its

continuous growth.

-Projected growth:

The estimated growth from previous years leads us to take a growth of 5% per

year.

-Economic:

On an economic scale, as Fanar expanding, the price of land increased from 200$

to reach 1200$ in 2014.

-Environmental:


7/28

Fanar is known for its green environment where we can notice the pine trees

covering most of its green spot and when it comes to soil the major soil type

across this city is sand and rocks.

-Industrial/buisnesses

Fanar holds a large number of companies and industries while it has a wide

variety of industries around 17 industries are registered and more than 300

companies are located in fanar.

-Pluviometry:

Average pluviometer registered in 2013 is 920mm per year.

-Water facilities:

Two containing tanks are located in fanar one on top of the area and the other in

the middle near municipality.

Water provenance is from Jal eldib (maslahat miyah Beirut) and from ain saadeh

on emergency basis.

There are two networks one for each reservoir and the reservoir themselves are

connected to each others. Water is pumped from Jal el Dib to the lower reservoir

and then pumped back to the higher one in case it is emptied. The other way

around is possible when they bring water from Ain Saadeh they fill the higher

one by gravity and then the second one if needed.

The piping network is in continuous expansion and there is no accurate track of

it and the as for the actual pipes map is either unavailable or inaccessible

information. If we cannot access the actual map we may have to assume the path

of the pipe for the scope of this project

Demand Analysis

Following the steps documented in the annex we can formulate the needs of the

town.

We seek to find:

Average Day Water Demand: ADD = Daily average water demand

Maximum Day Water Demand: MDD = 1.6 x ADD

Peak Hour Water Demand: PHD = 2.5 x ADD

Residential water demand:

ADD: Average daily water demand = 225 L/capita/day + 10%

We have 39000 capita assuming each one of them consumes 225 L and increased

10% we get 39000*225*1.1= 9,652,500L

Non-residential water demand

Commercial ADD: 16,800 L/ha/day

Light Industrial ADD: 22,500 L/ha/day

Wet Industrial ADD: 33,600 L/ha/day

We have 300 businesses assuming each of 200m2 leads to 60,000m2, which

converts to 6ha

ADD commercial equal 6*16,800 = 100,800L


9/28

We have 17 industries assuming a mix between light and wet for a usage of

30,000 L/ha/day and an average of 800m2 each ie 13600m2 = 1.36ha

ADD Industrial equal 1.36*30,000= 48,000L

Academicals water demand

Schools and universities ADD: 16,800 L/ha/day

We have 7 schools and 4 universities for an average area of 4000m2 each

44000m2 ie 4.4ha

ADD academicals = 4.4*16800= 73,920L

Adding all ADD we have 9,652,500L+100,800L+48,000L+73,920L=9,875,220L

Rounding up: ADD total = 10,000,000L

MDD = 1.6 x ADD = 16,000,000L

PHD = 2.5 x ADD (hr.) = 1,042,000L/hr.


10/28

Fire demand analysis:

The following fire flow targets are suggested in the absence of building

construction details based on the Fire Underwriters Survey Water Supply for

Fire Protection:

Residential Single-family: 100 L/s

Residential Multi-family: 200 L/s

Street side Commercial: 250 L/s

Elementary Schools: 167 L/s Junior and Senior High Schools: 267 L/s

Institutional: 250 L/s

Industrial: 383 L/s


11/28

Model Design

We fitted all pipes in EPAnet to be located under the road with as

much manhole as efficient to secure ease of repair and access without

having to damage the road pavement therefore minimizing car

accident traffic and other problems since fanar is a high traffic zone

with many schools.

The pipe characteristics:

Using HDPE (High Density Polyethylene) pipes:

Diameter =100mm

Roughness: C=150

Check appendix A2 with a table with all details regarding pipes

Junction characteristics:

The junction have right data imputed by estimating the roughly how

many building will be supplied and their type

The total supply have to be around the calculated projected AAD of

10,000,00

Check appendix A3 with a table with all details regarding junctions


12/28

Chosen trial network

The preceding image is a screenshot of EPAnet showing the loaded scaled map

from which we could determine the length of each using the built in function of

EPAnet: Auto-length


13/28

Figure: Network with clear legend of pipe and junction number

The boundaries where created on google maps creator then imported to googleearth from which we could get the exact elevation of each of our nodes


14/28

Consideration for the design

Fanar region has already a reservoir that is located at half altitude so we need apump to supply the high parts of the region as a first trial we used the followingpump curve:

We started the system and found that it all runs ok with no issue at all

Conclusion

As a first part of a greater project this paper is preliminary study for the fanararea and has been done the most accurately as possible with all assumptionsclearly stated and well documented.The purpose of this paper is to prepare for the following part that will be thenetwork and facilities for this town.For now we have developed all the water requirements of the town usingstandards and the data we could collect from the municipalities.Our main goal will be implement the actual facilities instead of building a new

one from scratch.
