Water Supply

Water supply

Present Water Supply sources;

  • Gambhir Line (Direct Supply)
  • ESR (3 Nos.)
  • Ground Borewells (350 Nos.)

Water Input from All sources to ABD Area

Following locations were identified as water inlet points to the ABD project Area;

  • Bada Ganpati Square on Gambhir Line (700 mm Trans. Main)
  • JINSI Hat ESR on Narmada Inlet (500 mm Feeder Main): JINSI Hat ESR of 3 ML capacity is located at almost in the centre of zone no 1 area. The JINSI Hat ESR serves dedicatedly to ABD command area.
  • Subhash Chowk ESR on Narmada Inlet (450 mm Feeder Main): Subhash Chowk ESR of 2.25 ML capacity is located at zone no 2 area. The Subhash Chowk ESR serves to command area of ABD.
  • Chhatribagh ESR on Narmada Inlet (600 mm Feeder Main): Chhatribagh ESR of 3.4 ML capacity is located in zone no 2. Chhatribagh ESR serves the command area of ABD project area completely.
Water Input to ABD Area
Source Location Water Supply
Devdharam WTP At Bada Ganpati Sq. 5.56 ML
Narmada JINSI Hat ESR 2.21 ML
Narmada Subhash Chowk ESR 2.72 ML
Narmada Chhatribagh 3.23 ML
Total Water Input at ABD Area 13.72 ML

Thus, the ABD Project area is receiving 13.72 ML water every alternate day for distribution to water consumers.

Direct Supply points

Apart from above, direct supply points or tapings to feeder mains were also observed in the project area. As the tapping points for sources are scattered and needs to install the flow meters for better accountability. It has been observed that in absence of flow measuring devices, the dispute between actual water supplied is a routine affair. Hence, IMC shall install flow meters immediately.

Present Service Reservoirs

There are 3 ESRs which are marked and shown in Figure.

Distribution System

The existing pipelines distribution network of the ABD Project Area are shown in Figure;

The total length of the existing distribution network in the ABD Project Area is around 76.53 km. % Share of Length of different pipes in the distribution system are 58% of the pipe length is of ACP, 22% is CI, 8 % DI, 3% HDPE, GI & PSC and 2% MS. The majority of pipe laid is Asbestos Concrete pipes. The distribution network of ABD project area is very old and dilapidated condition and most of the pipes required complete rehabilitation and revamping with inclusion of leak proof pipe and material in order to provide the quality water. The network assessment suggests high level of UFW in the existing network.

Service Connections

Ward wise connection details collected from IMC and estimated water connections is calculated based on the % ward area covered under the ABD project area for the corresponding ward. There may be approximate 11,854 connections in ABD area. This figure may increase as per actual condition which can be verified by property survey method.

Bore wells in Project Area

As per the data collected from IMC, there are total 350 nos. ground bore wells in the ABD Project area. The bore wells are being operated for average 2 to 3 hrs depending upon the water scarcity area. The energy bills are being paid by IMC. The locations of the bore wells are represented on the map;

Water Quality

Water Quality sampling is being performed by IMC at production as well as distribution level. The hygienic standards of safe and potable water supply to the consumer in IMC area rests with IMC. As per data provided by Water Quality Testing Department of IMC, for the period from Jan 2015 to Sep 2015, it can be observed that out of 12314 samples tested during 9-month period, 11091 samples were fit and 1223 samples tested unfit. 10% samples of the total samples tested were unfit for drinking water purposes.

Gap Assessment

Following are the critical issues prevailing with existing water supply system hence resulting into gap between water management & citizen services

  • Direct Supply: In current scenario, the bulk water supplied into the system has too many direct tappings for distribution of water resulting into pressure drop and non-filling of ESR and leading to unequitable distribution.
  • Metering: The city does not have any metered water connections. Hence, the quantity of water consumption and the physical losses in the city is difficult to be estimated. Due to absence of meters in the project areas, Flat rates are fixed for the consumers which vary from residential, industrial and for commercial connections. In absence, proper water tariff policy, there is increase in customer dissatisfaction and poor customer services.
  • Improper operational Zones: Serving area/ zone served by each elevated service reservoir (ESR) was not designed as per their capacity. Despite disarrayed service area, existing pipelines have been found laid in haphazard manner. Thus, the residents get water with less pressure. The operational zones are created with multiple tanks. There is common inlet and outlet for tanks. No integrated approach was observed of demand-supply management.
  • Water Leakages: There is substantial loss of water due to old and worn out pipelines leading to leakage. The water is also wasted in Community Stand Posts and through the Supply Network. There is substantial wastage in the public stand post during supply hours due to the free flow of water. In addition, there is significant leakage in the pipelines of which there is no systematic management for detection and repair. There is significant wastage in the house connections also due to intermittent supply where the beneficiaries throw away stored water and store again the fresh daily supply. In addition, there are more chances of having unauthorized / illegal connections in the distribution system.
  • Borewells: Inadequate distribution network resulting less coverage area and dependency on bore well water / hand pumps. The shortfall in supply coverage is presently made, to some extent, by ground water through motorized bore wells. Due to the rapid un-sustainable depletion, of the groundwater table, the deep motorized tube wells have become uneconomical due to energy and repairing cost vis-vis and low yield.
  • Monitoring System: There is no proper instrumentation to monitor flow- pressure in transmission & distribution network. In absence of proper instrumentation system there is no accountability for water supplied and distributed. This is leading to un-efficient operation of the system.

Future Demand

As per the DPR of water supply total demand of water in 2020 is 28.1 MLD. The calculation is done based on target of 150 lpcd of water in ABD area. The demand in 2035 and 2050 is 34.69 MLD and 42.09 MLD respectively.
