For Reduction In NRW/UFW
Presented by:Satya MehtaPurshotam Solanki
Guided By:Dr. Seri Chinnam Reddy
Few Important Terminologies
NRW- Non Revenue WaterUFW- Unaccounted for WaterULB- Urban Local BodiesSLB- Service level Benchmarks
Water: A brief introduction
Chemical formula: H2oEarth contains 70.9% water(glaciers:2.4%, oceans: 97%, river lakes ponds: 0.6%)
Earth's approximate water volume : 1360000000 km3
Water in India
Rainfall & snow melt combination: 1869 BCM (37% mobilized)
Average rainfall: 1170mmGround water: 431 BCM
Water supply in IndiaAccess to drinking water : 88% urban, 72% rural
Average water supply duration : 4.3hours/day (20 biggest cities)
Chandigarh highest (12hours/day) and Rajkot lowest (0.6hours/day)
Prahaladnagar, Ahmedabad is only fully metered ward in India with 24hours water supply.

Need of SLBsPerformance indicators for all stakeholdersStrom water, drainage and sanitation too do have
SLBsMany organizations do had their own reports and
surveys to define benchmarks which created confusion.
Water: only way to survive on Planet Earth
Water balance in typical Indian City
Research MethodologyResearch Objective:
1. A survey of Indian Municipal Corporation as an Initiative to share the best practices worldwide to reduce NRW / UFW in public water supply systems
2. Tries to find out current benchmark status in Indian Municipalities Exposure of ULBs’ policy makers with global standards
3. Type of awareness and efforts for fulfilling SLBs4. Technological Savviest approach of Indian
municipalities.
Research MethodologyTarget population1. Municipal Corporation ward’s corporators2. Water Departments of municipality
Research MethodologySample Size
Total: 45
15 from Ahmedabad15 from Rajkot12 from Jamnagar03 from Vadodara
Research MethodologySampling technique A combination of Convenient and Judgment Sampling.
Sources of DataSurvey via questionnaire (contact method) containing 11 different questions
Research MethodologyLITERATURE REVIEWSEAWUN Water Supply Benchmark Survey, (2003)Key objective of the SEAWUN benchmark survey is to give useful results back to the participants as well generally raise the awareness in South East Asia of the usefulness of benchmarking water supply companies and encouraging others to participate in coming years.
National City Water Survey, Washington D.C (2005)Its purpose is to provide a forum for discussion of issues impacting how cities provide and protect community water and wastewater services. This survey was intended to distinguish priorities among the problem issues, providing invaluable information for federal policy discussions.
Research MethodologyLIMITATIONS1. Time constraints, as only 10days per assignment
were allotted.2. Lack of Secondary Data, as it was the first ever
private project of such type in Gujarat Municipalities.
3. Budget constraint, data collection among 4 cities from authorities was extremely costly, including appointments, conveyance, boarding and lodging leading; Convenient and Judgment sampling, and sampling size of 45 in total from 4 cities.

FindingsWater supply is intermittent in nature. Still conventional approaches for solving water leakages are used.
24*7 water supply, still a distant dream due to, no 100% metering, no 100% connections.
Need of technological up gradation in ULBs
Policy makers and implementers need global exposure to know best international water management practises.
Suggestions Advance leak detection technology usage should be
considerably increased in ULBs. Water management consultancy should be taken by ULBs,
dignifying ample fund received from Centre and State for system up gradation.
SHGs should be formed among societies and cooperatives who take care of water and its usage in respective areas.
PPP propaganda should be on top of ULBs agenda in area of water management system.
Policy implementers should be given chance to gain access and experience Internationally reputed and acclaimed Municipalities for knowledge sharing and technical know-how of various aspects of managing public water utilities.
Programs even on rain water, storm water and re-processing of water should be carried out at a peak level, as OCED reports of water scarcity in Indian subcontinent by 2030.
