ISSUES IDENTIFIED IN WATER SUPPLY SYSTEM
Minimize Water Losses
No metering of domestic water
24.2% of Water Loss
Issues such as leakages and burst pipes, illegal connections, free connections and metering inaccuracies
Lack of Pressure
This lack in pressure results in the insufficient quantity of water being supplied to the end user
From Source to Sink
Total 50 MLD water is been supplied from Sardar sarovar dam
After that water is supply to Nabhoi pumping station
Then taken to Water treatment plants (WTP) at Charedi and Sarita
Then travelling from three level distribution network to end users
The journey of a thousand miles

BUILT-USE FACTOR METHOD
Demand assessed on the scale of spatial entities using unit % area.
UNIT WATER DEMAND METHOD
Estimation based on unit water demand coefficient multiplied by number of users.

Water Supply Line & Valve Data
Methodology for creation of Geometric Network
Flow Assignment
DELINEATING JUNCTIONS IN WATER LINE THROUGH GEOMETRIC NETWORK
Determine flow direction of edges when sources or sinks are set.
Geometric network models the flow of water through water mains that are connected by junction fittings.
PERFORMING UPSRTREAM & DOWNSTREAM TRACE
APPLICATION OF GEOMETRIC NETWORK
Trace network elements upstream or downstream from a point.
Water utilities can determine which valves to shut off when a pipe bursts.
Find all network elements upstream from many points and determine which elements are common to them all.
Calculate the shortest path upstream from one point to another.
Environmental monitoring stations can hone in on a source of pollution in streams.
