ABSTRACT –
The fundamental goal of a waterdistributionsystem istomeet
demand for water while maintaining the required standard of
quality. Maintaining a steady and safe water supply has
become a difficulty for many cities as a result of increased
development and water constraint. Problems such as
insufficient water supply with low pressure, pipe bursts,
excessive leakage, and nonrevenue water are on the rise. To
address these issues, a smart water system is required, which
provides quick and accurate procedures and technologies for
properly managing water distribution infrastructure. The
study based on a variety of public requests, as well as the
volumes of inflows and outflows from over-head reservoirs.
The study's specific goal was to use EPANET software to plan
and develop a water distribution network, as well as to
analyse a water distribution system. Three approaches were
used to forecast the population of Ambaji town over the next
three decades: Arithmetic Increase Method, Geometric
Increase Method, and Incremental Increase Method. The
expected population's water requirement for the following
three decades was alsocalculated. Ambajitown'sGoogleEarth
image was obtained. EPANET Softwarewasutilisedtoanalyse
pressure, head loss, and elevation using these data. Pressure
and elevation at various nodes, as well as head loss at various
pipes, were the results of this investigation. The findings of
data analysis in EPANET Software revealed that there is less
head loss, which is critical for maintaining the constant
pressure required for Ambaji's continuous water supply
system. Ambaji town's water distributionsystemwasdesigned
and analysed to provide a suitable water distributionnetwork
with minimal head loss, maximum pressure, and efficient
diameter. The design was created with the population growth
rate and the developing town in mind. As a result, theresearch
focuses on network analysis and draws conclusions regarding
the network's reliability.
1. INTRODUCTION
In India, population distribution is influenced by water
availability. It is vital to deliver the requisite water amount
through the effective design of pipe network to fulfil the
increased water demand due to the growing urban
population. The necessary pressure through a distribution
network is the most critical task in distributing desired
water quantity to individual consumers. Each locationinthe
distribution network must be provided with a specific
amount of water flow with all of the appropriate
specifications. In most Indian towns, water is only available
for a few hours each day, pressure is inconsistent, and the
water is of dubious quality. A pipe network system'sjobis to
deliver water at the right pressure and flow.
As a result, while building a pipe network, the primary goal
is to achieve appropriate pressure at the supply point in
order to deliver the required amount of water to the user.
The intended street plan and topography are often used to
develop a water distribution network. In this study, Ambaji
town was chosen to analyse and examine the network of
piped water delivery systems, whichisdoneinthecontextof
a 24-hour water supply system to determine pipe pressure,
velocity, and water age, among other things.
2 STUDY AREA
2.1 Area
Ambaji is a town in the district of Banaskantha, Gujarat,
India, located in the dantataluka.Itscoordinatesare24.33°N
72.85°E. It is located at a height of 480 metres (1,570ft).The
Araveli Hill Range surrounds it on all sides. Ambaji covers a
total area of about 15 km2.
2.2 Climate:
Ambaji is a fan of all kinds of weather. Summers are hot
and humid, with temperatures ranging from 26 to 46
degrees Celsius and strong winds. The temperature in the
winter fluctuates from 6 to 36 degrees Celsius. During this
chilly period, average rainfall is roughly 15 to 30 inches;
during the monsoon season, average rainfall is about the
same as in winter, with high rains on occasion. Because
Ambaji is located at an altitude of 480 meters, the weatheris
nice throughout the year.
The taluka of Danta is located in the western section of the
Banaskantha district and is connected to Rajasthan. In the
taluka of Danta, there are 181 villages and one town.
Because Danta is a tribal area, a largenumberofhandpumps
have been constructed, the bulk of which are operational,
and the people are reliant on hand pump water. Out of 181
communities, 152 are served by various regional water
delivery schemes,asshownbelow.Theremaining21villages
in the "Nal se Jal" taluka, which includes Palanpur, Danta,

Vadgam, and Amirgadh, must be covered under the
proposed augmentation water supply scheme. Seven of the
twenty-one settlementsare dispersedandlocatedata higher
elevation; therefore, they are not covered by any water
supply network.

2.3 Need of study:
1. The existing Ambaji town project is rated for 70 LPCD,
however the present supply is 140 LPCD.
2. Increased water demand as a result of improved
lifestyle.
3. Tourism and the marble industry have increased
business demand, and the nearbyAmbaji neighbourhood
has developed quickly.
4. Among India's 51 Shaktipith is a Hindu holy and
religious site.
2.4 OBJECTIVES:
• Future population and water demand forecasts
• Development of a water distribution network for Am
baji town and
• Analysis of a water distribution system for Ambaji to
wn
• Network analysis for Ambaji town using EPANET 2.0
3 METHODOLOGIES
3.1 Google Image
Ambaji's Google Earth image was downloaded. EPANET
Software was utilised to analyse pressure, head loss, and
elevation using these data. EPANET 2.0 has made use of
these data.
3.2 Population and water demand forecast for
Gandhinagar city
The population was forecasted using three methods as
shown below with formulae:
Arithmetic Increase Method:P
n
= [P

+n· ],
Geometric Increase Method:P
n
= P
0[1+ �/100]^�and
Incremental Increase Method:P
n
= P

+ n· +(�(�+1))/2·��
Where:
P
n
= Prospective or forecasted population after n decades
from the present, P
0
= Population at present, n = No. of
decades between now and future, = Average (arithmetic
mean) of population increases in the known decades, r =
Assumed growth rate (%),�� = Average of incremental
increase of the known decades.
The population was predicted to grow until 2041. Thewater
demand has also been calculated for the same. The
population forecasting is based on projections from the
Census Department of the Government of India for theyears
1971, 1981, 1991, 2001, and 2011. The results of the
Incremental Increase Method give a solid notion of
population expansion. The population estimatesforthenext
decade are 2021 (21243), 2031 (24676),and2041.(28050).
3.3 Water distribution system:
The layout of water distribution system can be divided into
four types:
i) Dead End System,
ii) Grid Iron System,
iii) Ring System,
iv) Radial System
The proper layout pattern should be chosen among the
several layout systems available. The distribution system is
meant to be a dead end system in this case. The location of
tanks, mains, and sub mains are all part of the system.
3.4 DETAILED ANALYSIS:
Ambaji's map and Google Earth The image was downloaded
in order to be analysed. In the figure, Ambaji's expanded
study area is marked for analysis. The pipe network in
Ambaji is seen in detail in Fig 2. The coordinates of Ambaji
are 24.33°N 72.85°E. Ambaji is taken in for a thorough
examination.

3.5 EPANET SOFTWARE:
The US Environmental Protection Agency created EPANET.
It's a computer programme that simulates hydraulic and
water quality behavior in pressurized pipe networks over a
long length of time. Pipes, nodes (pipe junctions), pumps,
valves, and storage tanks or reservoirs make up a network.
EPANET keeps track of the water flow in each pipe, the
pressure at each node, the water level in each tank, and so
on. Using Hazen-Williams hydraulic equations, main pipe
lines are created based on the needed discharge, pressure,
and flow velocity.
V=0.849C
HW
R
0.63
S
0.54
In which V= average velocity of flow in m/s, C
HW
= Hazen-
Williams coefficient, R=hydraulic radius (=A/P) in m, S =
Slope of the energy line (=h
f
/L).
The simplification becomes
h
f
= 10.68��1.852��1.852�4.87
In which L is length of pipe and D is diameter in meter and Q
is in cubic meter per second.
3.6 Elevation and base demand of nodes
The basic goal of a distributionsystemistocreateacceptable
water pressures at various places where customers'tapsare
located. Water may be forced intothedistributionsystemvia
gravitational system, pumping system, or combined gravity
and pumping system, depending on the level of thesourceof
water and that of the town, geography of the area, and other
local factors and considerations.
Google Earth is a virtual globe created by Google. The
distance between all of the nodes was measured using a
Google Earth image.
Node ID, Elevation, Base Demand, Pipe ID, and Length

Node 4 443 0.56 3 366
Node 5 447 0.3 4 199
Node 6 450 0.22 5 147
These pipes are corrosion-resistant and couldsurvivefor up
to 100 years.
On the map, a pipe network and nodes wereestablished,and
water demands at each junction were calculated using
EPANET. The Google Earth image was used to record the
elevation of the nodes and the length of each pipe.
4. CONCLUSIONS
The study "Continuous WaterDistributionNetwork Analysis
Using Geo-informatics Technology and EPANET 2.0 in
Ambaji Town" was conducted with the primary goal of
examining the current water distribution system and
determining ways to improve it.
The population of Ambaji was calculated using three
methods: Arithmetic Increase, Geometric Increase, and
Incremental Increase. The next three decades were
anticipated using the Incremental Increase approach, and
the water demand for that population was estimated.
EPANET 2.0 software was used to examine the current
pipeline network so that the idea of a continuous water
delivery system could be realised with proper pressure and
minimal head loss.
A Google Earth image of Ambaji town was obtained, and the
height of nodes and pipe lengths for roughly 75 nodes were
recorded. These data were then used in the EPANET 2.0
software to analyse pressure, head loss, and other factors.
This study indicated that the outcome result from EPANET
2.0 software i.e.; pressure, head loss, etc. were checked with
hydraulic equation and found to
