3. INTRODUCTION
 Water is fundamentally the inherent necessity of mankind and essential resource
of human civilization. Access to safe and clean water plays a vital role in social
and economic development and public health for any society.
 To meet the rising demand of water, ground water reserves are extracted in an
unplanned way which results depletion of ground water. The unplanned and
uncontrolled extraction of ground water coupled with water contamination
requires immediate remedial measures to optimize the water withdrawal in our
country which is already water stressed.
 The software helps improve your knowledge of how infrastructure behaves as a
system, how it reacts to operational strategies, and how it should grow as
population and demands increase.
 This study is helpful to have an insight for a comprehensive and diligent
procedure for designing new distribution network in haphazard developed rural
area. For designing of best economical hydraulic modeling of water distribution
system in Water GEMS software is used in this study.

 Water GEMS is a hydraulic
modeling application for water
distribution systems with
advanced interoperability,
geospatial model building,
optimization, and asset
management tools. From fire
flow and constituent
concentration analyses, to
energy consumption and capital
cost management, Water GEMS
provides an easy-to-use
environment for engineers to
analyze, design, and optimize
water distribution systems.

Barddhaman is the district
headquarter of Khandari
village. Kota is the gram
panchayat of Khandari village.
Latitude and longitude
coordinates are23.4281° N,
87.5852° E. the total
geographical area of village is
743.93 hectares.

7. Objective
 The main aim of the research work is to find out the
Hydraulic modeling of khandari rural drinking water
distribution network of a particular stretch with the
application of waterGEMS software with field survey and
data collection. The application of the modelling software is
efficient to manage a full network of Overhead reservoirs,
pipeplines and demand points.

8. METHODOLOGY

9. TopographicalSurvey
ConsumerSurvey
 Topographical survey has been
carried along existing road
network / pathways as maybe
required for detail design of the
water supply distribution
network beyond the surveyed
length. The survey shall update
all objects/ roads / steps / drains/
gully pits/ culverts etc., on both
sides of the road (black
bituminous top or concrete or
brick) edges including road
portion.
 The data collected from
household survey has been geo-
coded to the base map. This
database has been used for
assessment of water demand of
each property at the junction of
distribution network pipe and
thus the system has been
designed and modelled
accordingly.
Data Collection

10. Design & Analysis of Distribution Network
MASS CONSERVATION
• Σ inflow = Σ outflow
• Q1 + q2 = q3 + d
……………………..(1)
• D = q1 + q2 -
q3…………………… (2)
• Where Q = flow in or out of
the node and D = demand at
the node or nodal demand.
ENERGY CONSERVATION
• Total head loss for each link
(pipe) as hf and assuming
counter-clockwise flow
direction to be positive,
• Then:
• HL = hf 1 + hf 2 + hf 3
+……
• -Hf1-hf4+hf3+hf2=0
HEAD LOSS CALCULATION
where hL = head loss (Length),
q = flow rate (Volume/Time),
A = resistance coefficient, and
B = flow exponent. K =
minor loss coefficient, v = flow
velocity (Length/Time), and g =
acceleration of gravity
(Length/Time2)

19. Conclusion & Recommendation
 In this study, the empirical analysis of the water distribution network in the rural
area of the Barddhaman has been carried out using Water GEMS, a computer-
based simulation software for water distribution network. Prelude to the analysis,
a review of literature was carried out. The current conditions of water supply and
distribution in the study has been studied to explore the real need to have a
surface water based 24 X 7 water supply for the consumers within the study area.
Relevant data required for the analysis were collected. The results of all the
analysis were supported by charts, screen-shots &pictures in adherence to the
CPHEEO manual.
 With the use of this software one can indeed analize the network at the desk and
can foresee the error, if any, in the design and consequently the changes required
to be done in such designs for its successful execution at site. The result reveal that
the software used for the design has the capability to handle various pipe network
problems without changing in model of or mathematical formulation.
