1. Atpresentthereisintermittentsupplyofwater(onceinthreedays).
2. CurrentlytherearetwelveESRsaresupplyingwatertothedistributionsystem.Presentactualutilizedstoragecapacityis36MLonly[@43.85mlless(2x2.8)notinoperation&

3. Dueto limitationsofstagingheightofExistingESRs (11.5to15.5), it isdifficulttogetrequired residual head of 12.0m in Distribution network; hence it is necessary to
restructuretheexistingcommandarea.
4. About 86% of existingpiping is of PVC pipematerial laid before 20 year% of nonrevenuewaterisquitehigh,duetoageoldpipes,losses,unaccountability&theft.
5. Thereisnoconsumersatisfaction.Asthereisunequitablewaterdistribution&insomeclustersreceivewateratverylowpressure.

8. Also the existing components has completed their useful life or in deterioratingconditionhence it isnecessary to replace /rehabilitation them soas to increase their

1.12. OBJECTIVESOFTHEPROJECT:
The purpose of this report is to create a HydraulicModel of distribution network for

2. Checkthesuitabilityofexitingstorages&distributionnetworkforprospectivedemand,
2. Recommend a strategywhichwould help JalgaonMunicipal Council (JMC) tomakeoptimumutilizationoftheavailablewaterresources,withmaximumuseoftheexisting
watersupplyscheme,withbestpossibleefficiency.
3. Suggest proposed system for equitable distribution of water & meet prospectivedemandatdesiredpressure.
4. Suggestsuitablephasingoptionsforreplacementoldpiping&HSC,tominimizedNRWinsystem
5. Rehabilitation&Rationalizationofpumpingsystem
6. Suggestsuitablerehabilitationtoexistingsystem

B] CONTROLFORFLOWTHROUGHPIPE:
MBR is locatedatmuchhigherelevation. Supply fromMBR toESR is throughgravity.
Hence it is required to control flow at Branch line or inlet of few ESR. The control
required isespecially fortheESRs/sump located in initialstretchofthesystemorat
lowerlevelthanotherESRs,astheytendtodrawmoreflow.Thisaffectsthehydraulic
of whole system. While analyzing such reservoirs are identified and inlets flow is
proposedtobecontrolusingFlowControlValves(FCV).
Forexample,MIDCproposedESR1 inletpipe,which is locatedatthe initialstretchof
the system, is designed to have a flow rate of 800m3/hr by installing an FCV (flow
controlvalve)atitsinletpipe.
