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.

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

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.
