Total Water Losses /UFW/ NRW are 291 ml/Day i.e. 54 % of supply. OPEX is Rs 3.30/ 1000 ltrs. @ WTP ANNUAL ENERGY BILL OF Rs. 28 CRORE /YEAR

  17. NMC Water Supply: Income Expenditure (in Rs.Lakhs)

  18. NAGPUR WATER SUPPLY: Status before JNNURM Measurement Losses 125 mld Losses 20 mld 235 mld Commercial losses/ theft/metering error Raw water Purchase 625 mld TREATMENT 500 mld Distribution 480 mld Losses In canal Recovery 200 mld Physical losses Collection Losses 45mld 140 mld SYSTEM EFFICIENCY : 32% Annual Loss (W/O Dep): Rs 56 crore With Depreciation : Rs 75 crore (appx)

  19. Water sector Challenges: NMC • Water Losses and UFW • Equitable distribution (Alternate day / 20 hrs/day) • Accountability • Water to Slums (inefficient system) • Water network coverage and inadequacy of network • Water supply management during summer peak demand • Old and inefficient assets • Delay in capacity augmentation for future demand from Limited water sources. • Capital availability • Low water tariff and Poor billing mechanism. • Lack of professional approach.

  20. Inadequate maintenance of existing assets • Lack of operational expertise • High UFW • Strain on Water Resources • Tariffs not rational • Unsatisfied demand • Poor cost recovery • AUGMENTATION • Strain on water resources • Additional capital expenditure • STRATEGY • REFORMS IN WATER SECTOR • INVESTMENT SUPPORT FROM JNNURM • IMPLEMENTATION THROUGH PPP MODE FUNDING CONSTRAINTS THROUGH COMMERCIAL SOURCES MISMATCH BETWEEN INCREASING NEEDS & DECREASING RESOURCES FUNDING BURDEN ON NMC/STATE NMC Strategy

  21. NMC Strategy for Reforms in Water Sector • Fixing of Benchmarking and Performance indicators through Water audit, Energy audit & Financial reforms. • UFW/NRW reduction program with investment plan • Assets Up gradation plan for better serviceability and efficiency • Cost reduction program (Energy, Water & O & M Cost) • Improvement in services to consumer special emphasis to urban poor • Implementation of augmentation plans with inbuilt efficiencies. • Low cost Funds / Grant from Jn-NURM/ Tax free bonds/ PPP • Performance based contract with 5 to 25 years of O & M with private participation • Quality & Cost based selection criteria for contractors, consultants and Operators. • Rationalization of Water Tariff and Billing with Meterisation. • Capacity building of NMC employees by exposure and training. • Review of water supply master plan with inclusion of water reuse option ………………..Moving towards Continuous Water Supply in Nagpur

  22. STEPS TAKEN BY NMC FOR BETTER EFFICIENYIN WATER SUPPLY • Water & Energy efficiency Project worth Rs. 96 crore has been approved and funds received from JNNURM • Reduction in Raw water UFW by 100 mld (Annual savings of Rs. 2.0 Crore on investment of Rs. 35 lakhs) • Water Audit & Leak Detection Phase-I of Rs. 28.0 Crore. (Step towards bringing down the UFW to less than 25%) • Energy Efficiency Program of Rs 25.00 Crore is under implementation. (Reduction in energy consumption by 20%) • Up gradation & Expansion of Distribution Network of Rs 43 Crore (To increase the coverage of piped water network to 100% and equitable distribution of water)

  23. STEPS TAKEN BY NMC FOR BETTER EFFICIENYIN WATER SUPPLY • Pench-4 : Aug. water to supply project through reduced water losses in canal. : Rs 422 crore has been sanctioned under JNNURM (project cost increase to 550 crore) • New Water Supply Policy for Slums. To reduce UFW and service to urban poor. • Rationalisation of Water Tariff. (To recover O & M Cost + Telescopic tariff for water conservation) • Up gradation of Kanhan water supply systems (Project cost Rs. 83 crore sanctioned under JNNURM ) (Optimum Utilisation of water resources) • Water Reuse Projects under WENEXA-II: To make the region water surplus : Project cost Rs.131 crore sanctioned under JNNURM • Resolution by General Body for PPP mode to implement 24x7 project

  24. Water Tariff for Conservation and Sustainability • Water Tariff for full cost recovery for sustainable water business. • Subsidized Tariff to Urban poor and low domestic consumption 55 lpcd • Tariff at cost for domestic consumption up to 135 lpcd • Premium Tariff for domestic consumption beyond 135 lpcd and non domestic usage • Indexation with raw water and energy charges. It enable to pass additional cost (70% of operating expenses) directly to consumer as surcharge. • Tariffs are sufficient to meet Operating expenses and repay the loan for Jnnurm Projects • Earning will be better with operational efficiency and reduction in Non Revenue Water.

  25. Tariff Revision

  35. Source of Losses (Physical + Commercial) • House service connection : 63% of reported leak complaint • Old conservancy lane / G I Pipes • Old Lead Joints / Valve leaks • 70% of non working meters • Illegal connections • Poor quality of meters • Absence of water accounting

  36. Strategy For Water Loss Control

  37. Pilot 24x7 Pilot Project • Feature • 15000 Connection including slum • 10 slum areas • Population 1.5 – 1.75 lakhs • Contract • Study, Rehabilitate, Operate contract with Private operator. • Penalty /bonus for targets in UFW, Quality, Customer services and Continuity of supply

  38. Pilot 24x7 Project :Baseline for Private Operator

  39. Rehabilitation Plan for Pilot 24x7 • Replacement of 100% House service connection & Meters • Replacement of old conservancy GI pipe • Rehabilitation of Tertiary network • Hydraulic modeling as per Master plan • Installation of new billing system • Customer Facility centre

  40. 24x7 WATER SUPPLY : OBJECTIVES “Water for all and 24 x 7 supplies with focus on safety, equity, and reliability”. • Continuous water supply at desired pressure. • No Contamination of water • Reduction in water losses • Better Accountability • Better Service to Consumer • Sustainability of system

  41. Investment for RehabilitationJNNURM Phase-2 • Replacement of House connection • Replacement of consumer meters • Replacement of deteriorated pipes and fittings • Rehabilitation of ESR/GSR. • Rehabilitation of Pench-II WTP • Rehabilitation of Misc component • Implementation of Slum Policy

  42. Public Private Partnership in JNNURM Projects Project Finalized Under JnNurm Pench-I WTP Improvement & Up gradation (Rs 6.42 Crore) 70% grant in aid, 30% by private operator 5 Years O & M by operator Water reuse For Power Plant (Rs 130 Crore) 70% grant in aid, 30% by Mahagenco 30% O & M by Mahagenco & pay to NMC the raw sewage charges @ Rs3.0 – 3.50 per 1000 Ltr for 110 MLD. Annual revenue to NMC Rs 15 crore from sewage 24/7 Water Supply (Rs 20 Crore) 5 years O & M with performance based targets to reduce UFW and improvement in service level to customers in a pilot zone of 1.25 lakhs population. Improvement to Kanhan Water Supply (Rs 65 Crore) 70% grant in aid, 30% by private operator 15 Years O & M by operator Water Distribution Monitoring System

  43. Implementation Options • OPTION-1: INVEST JNNURM MONEY KEEPING EXISTING MANAGEMENT PRACTICES AS IT IS WITH ASSUMPTION THAT ALL PROBLEMS ARE WITH PUMP AND PIPES. • OPTION-2 : INVEST JNNURM FUND IN THE WATER SUPPLY SYSTEM AND IMPROVE THE MANAGEMENT & ACCOUNTABILITY.

  44. PPP Definition and Basic Principal • Public Private Partnership • Partnership • Ownership : NMC • Operation: Private • Investment: Both • NMC to decide Tariff • NMC to decide Development Plan for City • Private Partner to Operate the system. • Private Operator to earn profit through efficiency in Implementation and operations

  45. Private Participation in Water Sector :Exist in NMC • All new assets created since 1999 is managed though service contract. • Existing assets also managed thru service contract for Pumping station/ WTP O&M / Valve operations/ Billing distribution/ Annual maintenance contract for Zonal level • Disadvantages • It is only a labor contract replacing retired employees. • No link with performance • No accountability towards consumer • Short term Contracts break up in small parts with no feasibility for private investment • Contractor motivated for providing short term solution

  46. Private Participation in Water Sector :Exist in NMC • Advantage : • Reduced number of NMC employees as of now 80% of assets managed by private contractors • Short term annual contract can be replaced by better contract • Non performing contactor can be replaced by better one • Reduced O & M cost • Over the period of time capacity building of local contactors in O & M • Prepared the ground for larger involvement of Private participation without affecting the NMC employees. Hence, less resistance for PPP.
