1 REGULATING URBAN WATER DEMAND & NON-REVENUE WATER IN A WATER SCARCE STATE A MAJOR CHALLENGE FOR 24 BY 7 WATER SUPPLY IN RAJASTHAN Anil Dutt Vyas, Head Civil Engineering Department, Manipal University Jaipur, India Prof Rohit Goyal, Dean Planning & Development, Malaviya National Institute of Technology, Jaipur, India

2 Snap Shot : Rajasthan Water Scenario
Rajasthan is possibly the driest state in India Uncertain rainfall confined to two/three months of the year. West of Aravali, lies Thar Desert with an average rainfall of just mm Eastern part is humid & rainfall ranges between 400 to mm The average rainfall for the State about 570 mm.( National average 1170 mm). Out of 237 blocks in the state, 207 were in the dark zones while only 30 blocks have groundwater left as per last survey. The cattle owners also facing acute shortage of water. Drought like situation in 26 out of 33 districts of Rajasthan

3 Snap Shot : Rajasthan Water Scenario
There are 14 defined river basins in the State but Chambal and Mahi are the only perennial rivers. Surface water available in all basins: BCM Only 60 percent/ BCM considered economically usable. The current demand-supply deficit is 8 BCM, and is expected to go up to 10 BCM by 2017. Water supply once in 24 hours for 161 towns, once in 48 hours for 49 towns, and once in 72 hours in 12 towns. The annual water table loss is 1 to 3 meters at many places. Around 90% of drinking water is met by groundwater.

4 Snapshot : Rajasthan Urban Sector
Total State population about 69 million With the same trends a) population likely to increase to million in 2020 b) million in 2040 c) million in 2060. Urban population around 17 million ( about 25% ) Increasing rate 3.08% per annum. Number of urban local bodies (ULBs): 185

5 Snapshot : Urban Water Sector
Increasing water demand due to rapid urbanization. Demand exceed Supply. Illegal water connection and poor metering system effect both supply of water and revenue generated from it. Water loss due to leakage is 40 to 50%. Out of 185 ULBs , 183 covered by piped water supply 23 ULBs providing more than 100 lpcd, (SLB of135 lpcd MoUD) 79 ULBs provide 60–80 lpcd 74 ULBs provide 40–60 lpcd 1. Rajasthan Urban Policy According to the State Planning Department

6 Water Quality Scenario Rajasthan
70% of habitations in the state face problems getting potable drinking water. The available water has high total dissolved solids (TDS), salinity, fluoride, and nitrates. Fluoride > 1.5 PPM: Tonk, Churu, Barmer, Pali, Sirohi, Jalore, Rajasmand Nitrate > 100 ppm: Churu, Nagaur, Jhunjhunu TDS > 2000 ppm: Churu, Barmer, Bharatpur Iron > 1ppm: Bhilwara, Jodhpur, Baran, Jaipur Source: [1]

22 Demand v/s Gap

23 Gap v/s NRW

24 Urban Jaipur- The Capital City
In the past one decade, the groundwater level in the city has depleted by 25 metres. All the 13 blocks in the city have been declared as dark zones by the Central Ground Water Board (CGWB). From 2004 to 2014, the groundwater table in Amber block fell metres, while in Bassi, it fell 18 metres. Rampant construction and concrete flooring have virtually blocked all natural inlets. Withdrawal is very high as million litres of water every day, which is 200% more than the rate at which this source is getting recharged. Very wide gap between the demand and supply. The real estate developers are drawing groundwater for construction and drinking purposes.

25 State Government Initiatives
Under Cairn India's Jeevan Amrit Project, kiosks with reverse osmosis (RO) plants have been installed to provide safe drinking water in some villages in Rajasthan. Signed a fresh agreement under the above 'Jeevan Amrit Project', in which 333 RO plants will be installed in over 800 villages of the district Jodhpur . Model was conceptualised keeping in mind some difficult areas in order to ensure 24x7 availability of quality drinking water in the highly water-starved areas. Pilot projects on 24 by 7 water supply in Jaipur.

26 Pilot Projects on 24 by 7 water supply in Rajasthan
Location: Mansarovar of Jaipur city Initiated on: November, 2010 Agenda of the project: Supporter of the projects: Pilot Activities Undertaken Baseline data collection Conducting IEC campaign District Metered Area (DMA) creation Converting intermittent water supply into 24X7 water supply Eco-Asia, Ranhill Malaysia, Maharastra Jeevan Pradhikaran and PHED Rajasthan0 Source: Demand Response Pilot Project for JVVNL Discom, Jaipur, India:

27 RUIDP/ADB RUPID Phase -1
6 divisional headquarter cities of Ajmer, Bikaner, Jaipur, Jodhpur, Kota and Udaipur were included. The major focus areas were - water supply, waste water management, solid waste management, maintenance of the road, Drainage, Medical, health etc. Total project cost was around US$ 362 million in addition, Asian Development Bank contributed around US$ 250 million. Source: [1]

28 RUPID Phase -2 Rajasthan Urban Sector Development & Investment Programme (RUSDIP), ADB approved financing the phase-II in three tranches after the success of Phase -1. Project is to develop the living conditions & urban environment, enhance social and economic development of 15 urban centres in Rajasthan. Total project cost was around US$ 273 million was signed in 2008 till June 2015. Source: [1]

29 RUPID Phase -3 The major focus will be on - water supply distribution network improvement; sewerage system including sewerage network and treatment plant; house service connections in water supply and sewerage sectors; recycling of waste water etc. On October 24, 2014 ADB gives loan of US$ 500 million to RUSDP and the total size of the program would be US$ 610 million. The loan will be used in improving and strengthening water distribution network and sewerage systems in the 6 cities namely - Sriganganagar, Hanumangarh, Jhunjhunu, Pali, Bhilwara and Tonk.

30 Preliminary Results of the Study
On an average it shows 40 to 50 NRW in major cities but practically the losses are much higher. Cost recovery is almost less than 10 % in most of the urban centres including the Jaipur Average duration of supply was on average just 30 minutes/day ( Jaipur 1 hr/day) This is because of inadequate management of the distribution system & all the systems. Results in contaminated water Metering varies from 20 to 90 % Coverage of piped water supply is still poor around %. Except few key towns there are no proper customer grievance redressal centres

31 Conclusions Efficiency of billing needs to be monitored rigorously.
Latest metres /advance meters/remote meters reading to be used. Extensive pipe coverage to be prioritized in uncovered areas. The urban poor blamed for high levels of NRW, especially due to illegal connections. High willingness to pay for piped water supply among the poor. In order to give illegal connections to informal settlements inferior quality of pipes are used, leading to substantial losses. More focus on tariff mechanism ,human resources at ULBs & so on. The urban poor suffer most from this situation
