Issues & Challenges
Presented by
SATISH JAIN
Executive Engineer,
City Division I (North), Jaipur
HISTORY
 Jaipur Water Supply is more than 100 years old,
initially fed by local Open wells, augmented in
the year 1918 based on ground sources (16 large
dia open wells on Amanshah Nallah bed) and
tap water supply at common points introduced.
 7.0 MLD of water production added from
surface source Ramgarh Dam in 1952. Later
augmented for 27 MLD in late sixties.
 The limited availability of surface water realized.
HISTORY contd…
 Tube well drilling introduced in late sixties,
augmentation from tube wells also started.
 Final augmentation from Ramgarh lake for 45
MLD in the year 1982.
 Allocation of water from Bisalpur Dam (11
TMC) work on ground started in the year 2006.
 Meantime, water production augmented from
ground sources, 2009 City gets Bisalpur water.

Water supply system
 Six water transfer pumping stations are operated for transfer of
Bisalpur water at designated head works. Water transfer system is
operated and monitored on SCADA.
 Water from tube wells is collected in local head works and
transferred to deficit areas.
 Water supply to consumers is from local head works through
Clear Water Reservoirs, Pumping Stations, Service Reservoirs
and Distribution system.
 Old city area, Walled City is fed from distant Pumping stations
located at Amanishah, Ramniwas Garden and Laxman Doongri
Head works due to absence of local storage reservoirs.
 The water supply is intermittent and average duration is from
120-90 minutes per day.
 Dedicated Laboratory for daily monitoring of water quality.
Bisalpur System
 The Bisalpur System consists of two parts
 Transmission System
 Transfer System.
 Transmission System consists of
 Raw water from Bisalpur Dam is pumped to filter
plant 400 mld at Surajpura
 Filteration and Chlorination at filter plant
 Treated water is transferred to rural areas and
Jaipur City upto Balawala pumping station

well as unconnected areas of city throughout the year.
 Improvement in distribution system completed in many localities
like; Top Khanna Hazauri, Mandi Khatikan, Kanwar Nagar,
Kamela Ki gali, Jagatpura etc.
 Till Year 2010, Nos of tanker trips during summers was about
2800. The present no of trips is about 1000. Out this about 300
are running in outer unconnected areas and balance in the
connected areas.
 March 2012; Tanker tracking system introduced, all tankers fitted
with GPS and payment as per trips recorded in GPS.
 Distribution system improvement works in progress and in
coming summers tanker trips may further reduce.

Water Quality Assurance and Monitoring
 Regular chlorination of water is done by
bleaching powder at pumping stations.
 Pumping stations under Bisalpur Project are
provided with gas chlorination.
 100 online chlorination plants has been installed
on direct supply tube wells.
 12 Electro-chlorinators are installed at pump
houses.
 Daily water samples collected for residual
chlorine and bacteriological examination.
Present Scenario of Ground Water
 As per studies there is an over drawl of more than 600% of
ground water in Jaipur City.
 No more recharge basin available for city to meet the high
water demand of rapid urbanization.
 Areas such as Jhotwara, Murlipura, Jagatpura, Malviya Nagar,
part of Mansarovar, Bapu Nagar, C Scheme, Jawahar Nagar
etc are almost dry.
 Increased rate of tube well failure due to drop in water table.
 Reduced yield of new tube wells being constructed in recent
years.
 In addition to tube wells drilled by department for drinking
water there are large number of tube wells drilled by private
owners, using water indiscriminately.
 Depleting water table adversely affecting quality of water.
Remedial Measures Ground Water
 Drilling of tube wells prohibited without prior permission.
Committee headed by District Collector empowered to issue
permissions for drilling of tube wells after examination of need.
 Construction of Rain water harvesting structures is mandatory for
houses with more than 300 Sqm.
 100 Roof top artificial recharge structure constructed in govt.
buildings and public parks etc. by JDA
 Artificial recharge structures constructed at road side depressions
where water is accumulated for small duration during rainy season.
 Department constructed 100 artificial recharge structures on
abandoned tube wells in the year 2011-12.
 Efforts are on to persuade Industrialist with big plots and sheds with
huge open areas to construct rain water harvesting structures and
artificial recharge structures for recharging the aquifer.
Problems in Distribution Management-1
 Illegal connections and Long distance connections.
 Equitable distribution of water in distribution zones
 Low pressure, short supply and tail end problems
 Incidences of water pollution due to choking/over
flowing sewers & seepage from manhole chambers.
 Increase in demand of new water connections from
consumers due to reduced yield of ground water in
private tube wells.
Problems in Distribution Management-2
 Increasing numbers of multi story buildings in
developed areas demanding bulk water.
 Water supply to planned areas developed by private
colonizers in outer areas of city.
 Water supply to unconnected areas within zones.
 Curb on demands for Tanker transported water.
 Poor utility and asset mapping affecting monitoring.
 High non revenue water and water wastage at
consumer end due to insignificant water tariff.
Planning for Distribution Management-1
 Illegal connections: Consumers counseled for regularization of
illegal connections.
 Distribution system Improvements: Distribution network
strengthened by providing additional pipelines, Orifice flow
equalizers installed at connections with high pressure and
Leaking valves replaced to curb 24 hrs water in lower zones.
 Reduction of water losses: Water Audit started from year 2011
with complete accounting of water quantity right from all
sources to consumer end. (NRW reduced from 42 to 32% and
savings provided for useful water )
 Pollution control Measures: The pollution prone areas combed
and affected pipelines with service connections replaced. Three
level water quality monitoring system introduced including
mobile units for daily monitoring. (Resulted in almost 50%
reduction in incidences of polluted water supply)
Planning for Distribution Management-2
 Demand management: New water connection guidelines
introduced to curb use of water in non drinking purposes like;
construction, washing, industry & process etc.
 Demand for Multistoried buildings and New areas: Policy for
release of connections in multistoried buildings implemented
with provisions for bulk metering, RWH and recycling.
 Water Supply to areas developed by Private colonizers: Detailed
proposal and policy for providing water supply to outer areas is
under preparation. Provisions for sharing of infrastructure cost
and rationalized tariff to recover O&M cost are likely to be set.
 Utility and Asset Mapping: Consultant appointed for preparation
of GIS based complete mapping of water utility and other assets.
Pipeline networks already updated and clause inbuilt in all work
contracts for simultaneous updating of maps.
 High NRW: Reduction of NRW in 4 pilot areas with JICA.
Assessment of water supplied
 Metering is an important tool for water management.
Anything which is not measured is not managed.
 There are total 384058 metered connections in Jaipur Water
Supply Scheme.
 In general about 60 % consumer meters are functional.
Replacement of water meters is not been done due to
shortage of staff, low meter repair rate.
 A broad policy for replacement of consumer water meters is
under process of approval and it is proposed to out source
the work. Providing and installation of FCRI tested water
meters for 7 years including O&M and replacement
guarantee may be introduced soon.
Energy Efficiency
60 % of O&M Cost is towards Energy Charges
MEASURES FOR IMPROVING ENERGY EFFICIENCY:
 400 old inefficient submersible pumping sets of
tube wells replaced.
 Policy for procurement of Star rated energy
efficient implemented.
 Drive for replacement of In efficient centrifugal
Pump sets started to save energy.
 Operation of tube wells with time switches.
Major Ongoing and proposed works
 Work of laying 600 mm pipeline in Ghat Bazar to improve
pressures in Choukri Ghat, Ramchanderji, Top Khanna Hazauri,
Modi Khanna, Vishwarji. Pipe line in Top Khanna Desh has
been commissioned, tail end pressures has been increased by 3m.
 The interconnections and providing of missing pipeline links is
under progress in many areas for pressure improvement.
 Development of new distribution zone for Kho Nagorian under
construction.
 WSS for Sewerage farm area sanctioned, under tendering.
 200 ML Filtration Capacity addition at Surajpura WTP
 Survey and feasibility started to bring additional surface water in
Bisalpur dam from river Chambal.
 Proposal for additional Surface water from Isarda Dam.
24 X 7 water supply in pilot areas
 A MOU was signed among Ranhill Co Malaysia MJP and Govt.
of Rajasthan
 Pilot project for 24 hrs water supply started in 4 zones of Jaipur
City to study NRW and consumption behaviour.
 Mansarovar Sec 1
 Mansarovar Sec 3
 Mansarovar Sec 9
 Malviya Nagar Sec 9
These zones were provided with separate pipe lines from Service
Reservoir along with bulk meters for DMA metering. Non
functional consumer meters also replaced. Daily meter reading
of consumer meters and bulk meters.
24x7 contd..
 The sector wise number of consumers are Mansarovar Sec 1 –
139, Sec3 -295, Sec 9 – 135 and Malviya Nagar Sec 9 – 140 .
 During execution of work IEC activities done to educate
consumers for water conservation and checking of all possible
leakages in side consumer property. It was observed that there
were major leakages from the under ground water storage tanks,
fittings and poor plumbing equipments.
 The results of pilot study are encouraging, in general the water
demand has remained slightly higher than intermittent supply.
 Leakage levels have come down both in the distribution system
and at the consumer end.
 It is proposed to extend coverage in the adjoining areas and
replicate in other distribution centers; Kanwar Nagar, Jawahar
Nagar & VDN Nagar etc.
Policy and Governance related Issues
 Inadequate staff for regular O&M: Out sourcing of services and
SPR basis contracts floated with defect liability clauses.
 Low Water tariff leading to higher consumptions: No hike in
water tariff for last more than 18 Years but as per the State govt
policy drinking water is a basic requirement. Proposal for water
tariff reforms is now under process to rationalize tariff for
lifeline consumptions and charge higher rates on volumetric
consumptions to curb excessive use and wastage.
 Poor Cost recovery of O&M Expenditure: The water for Jaipur
city is pumped from Bisalpur dam, at a distance of 110 KMs with
almost 95 Mtrs. of Hydraulic head. More than 50% of O&M
expenditure goes on power charges alone. The proposed tariff
reform is likely to address the cost recovery of O&M charges.
Consumer related Issues
 Improvement of O&M efficiency: Action plan to improve
operational efficiency of schemes is drawn to attain minimum
65% efficiency and performance. Supply Pressure and duration
time improved by 10-15%
 Poor Water Revenue collection: Revenue collection drive started,
Collection efficiency improved by 20%. Local Kiosk for bill
collection started from this month. On line water bill payment
also introduced for easy payment.
 Consumer Complaints: Resolve time prescribed for different
categories of complaints. Toll free Call centre facility introduced
for water supply related complaints. Online monitoring of
complaints resolved started. Very Good results achieved .

  • 22. Water Quality Assurance and Monitoring  Regular chlorination of water is done by bleaching powder at pumping stations.  Pumping stations under Bisalpur Project are provided with gas chlorination.  100 online chlorination plants has been installed on direct supply tube wells.  12 Electro-chlorinators are installed at pump houses.  Daily water samples collected for residual chlorine and bacteriological examination.
  • 23. Present Scenario of Ground Water  As per studies there is an over drawl of more than 600% of ground water in Jaipur City.  No more recharge basin available for city to meet the high water demand of rapid urbanization.  Areas such as Jhotwara, Murlipura, Jagatpura, Malviya Nagar, part of Mansarovar, Bapu Nagar, C Scheme, Jawahar Nagar etc are almost dry.  Increased rate of tube well failure due to drop in water table.  Reduced yield of new tube wells being constructed in recent years.  In addition to tube wells drilled by department for drinking water there are large number of tube wells drilled by private owners, using water indiscriminately.  Depleting water table adversely affecting quality of water.
  • 24. Remedial Measures Ground Water  Drilling of tube wells prohibited without prior permission. Committee headed by District Collector empowered to issue permissions for drilling of tube wells after examination of need.  Construction of Rain water harvesting structures is mandatory for houses with more than 300 Sqm.  100 Roof top artificial recharge structure constructed in govt. buildings and public parks etc. by JDA  Artificial recharge structures constructed at road side depressions where water is accumulated for small duration during rainy season.  Department constructed 100 artificial recharge structures on abandoned tube wells in the year 2011-12.  Efforts are on to persuade Industrialist with big plots and sheds with huge open areas to construct rain water harvesting structures and artificial recharge structures for recharging the aquifer.
  • 25. Problems in Distribution Management-1  Illegal connections and Long distance connections.  Equitable distribution of water in distribution zones  Low pressure, short supply and tail end problems  Incidences of water pollution due to choking/over flowing sewers & seepage from manhole chambers.  Increase in demand of new water connections from consumers due to reduced yield of ground water in private tube wells.
  • 26. Problems in Distribution Management-2  Increasing numbers of multi story buildings in developed areas demanding bulk water.  Water supply to planned areas developed by private colonizers in outer areas of city.  Water supply to unconnected areas within zones.  Curb on demands for Tanker transported water.  Poor utility and asset mapping affecting monitoring.  High non revenue water and water wastage at consumer end due to insignificant water tariff.
  • 27. Planning for Distribution Management-1  Illegal connections: Consumers counseled for regularization of illegal connections.  Distribution system Improvements: Distribution network strengthened by providing additional pipelines, Orifice flow equalizers installed at connections with high pressure and Leaking valves replaced to curb 24 hrs water in lower zones.  Reduction of water losses: Water Audit started from year 2011 with complete accounting of water quantity right from all sources to consumer end. (NRW reduced from 42 to 32% and savings provided for useful water )  Pollution control Measures: The pollution prone areas combed and affected pipelines with service connections replaced. Three level water quality monitoring system introduced including mobile units for daily monitoring. (Resulted in almost 50% reduction in incidences of polluted water supply)
  • 28. Planning for Distribution Management-2  Demand management: New water connection guidelines introduced to curb use of water in non drinking purposes like; construction, washing, industry & process etc.  Demand for Multistoried buildings and New areas: Policy for release of connections in multistoried buildings implemented with provisions for bulk metering, RWH and recycling.  Water Supply to areas developed by Private colonizers: Detailed proposal and policy for providing water supply to outer areas is under preparation. Provisions for sharing of infrastructure cost and rationalized tariff to recover O&M cost are likely to be set.  Utility and Asset Mapping: Consultant appointed for preparation of GIS based complete mapping of water utility and other assets. Pipeline networks already updated and clause inbuilt in all work contracts for simultaneous updating of maps.  High NRW: Reduction of NRW in 4 pilot areas with JICA.
  • 29. Assessment of water supplied  Metering is an important tool for water management. Anything which is not measured is not managed.  There are total 384058 metered connections in Jaipur Water Supply Scheme.  In general about 60 % consumer meters are functional. Replacement of water meters is not been done due to shortage of staff, low meter repair rate.  A broad policy for replacement of consumer water meters is under process of approval and it is proposed to out source the work. Providing and installation of FCRI tested water meters for 7 years including O&M and replacement guarantee may be introduced soon.
  • 30. Energy Efficiency 60 % of O&M Cost is towards Energy Charges MEASURES FOR IMPROVING ENERGY EFFICIENCY:  400 old inefficient submersible pumping sets of tube wells replaced.  Policy for procurement of Star rated energy efficient implemented.  Drive for replacement of In efficient centrifugal Pump sets started to save energy.  Operation of tube wells with time switches.
  • 31. Major Ongoing and proposed works  Work of laying 600 mm pipeline in Ghat Bazar to improve pressures in Choukri Ghat, Ramchanderji, Top Khanna Hazauri, Modi Khanna, Vishwarji. Pipe line in Top Khanna Desh has been commissioned, tail end pressures has been increased by 3m.  The interconnections and providing of missing pipeline links is under progress in many areas for pressure improvement.  Development of new distribution zone for Kho Nagorian under construction.  WSS for Sewerage farm area sanctioned, under tendering.  200 ML Filtration Capacity addition at Surajpura WTP  Survey and feasibility started to bring additional surface water in Bisalpur dam from river Chambal.  Proposal for additional Surface water from Isarda Dam.
  • 32. 24 X 7 water supply in pilot areas  A MOU was signed among Ranhill Co Malaysia MJP and Govt. of Rajasthan  Pilot project for 24 hrs water supply started in 4 zones of Jaipur City to study NRW and consumption behaviour.  Mansarovar Sec 1  Mansarovar Sec 3  Mansarovar Sec 9  Malviya Nagar Sec 9 These zones were provided with separate pipe lines from Service Reservoir along with bulk meters for DMA metering. Non functional consumer meters also replaced. Daily meter reading of consumer meters and bulk meters.
  • 33. 24x7 contd..  The sector wise number of consumers are Mansarovar Sec 1 – 139, Sec3 -295, Sec 9 – 135 and Malviya Nagar Sec 9 – 140 .  During execution of work IEC activities done to educate consumers for water conservation and checking of all possible leakages in side consumer property. It was observed that there were major leakages from the under ground water storage tanks, fittings and poor plumbing equipments.  The results of pilot study are encouraging, in general the water demand has remained slightly higher than intermittent supply.  Leakage levels have come down both in the distribution system and at the consumer end.  It is proposed to extend coverage in the adjoining areas and replicate in other distribution centers; Kanwar Nagar, Jawahar Nagar & VDN Nagar etc.
  • 34. Policy and Governance related Issues  Inadequate staff for regular O&M: Out sourcing of services and SPR basis contracts floated with defect liability clauses.  Low Water tariff leading to higher consumptions: No hike in water tariff for last more than 18 Years but as per the State govt policy drinking water is a basic requirement. Proposal for water tariff reforms is now under process to rationalize tariff for lifeline consumptions and charge higher rates on volumetric consumptions to curb excessive use and wastage.  Poor Cost recovery of O&M Expenditure: The water for Jaipur city is pumped from Bisalpur dam, at a distance of 110 KMs with almost 95 Mtrs. of Hydraulic head. More than 50% of O&M expenditure goes on power charges alone. The proposed tariff reform is likely to address the cost recovery of O&M charges.
  • 35. Consumer related Issues  Improvement of O&M efficiency: Action plan to improve operational efficiency of schemes is drawn to attain minimum 65% efficiency and performance. Supply Pressure and duration time improved by 10-15%  Poor Water Revenue collection: Revenue collection drive started, Collection efficiency improved by 20%. Local Kiosk for bill collection started from this month. On line water bill payment also introduced for easy payment.  Consumer Complaints: Resolve time prescribed for different categories of complaints. Toll free Call centre facility introduced for water supply related complaints. Online monitoring of complaints resolved started. Very Good results achieved .
