  1. DEVELOPMENT OF AN EFFECTIVE WATER DEMAND MANAGEMENT PROGRAMME BY A MUNICIPALITY: CITY OF EKURHULENI’S EXPERIENCE May 2019 S

  2. WHAT WILL BE PRESENTED? • Problem Statement • Objectives • Water Loss Indicators for the City of Ekurhuleni • Element of Water Demand Management Programme • Interventions • Conclusion

  3. PROBLEM STATEMENT • SA average annual rainfall is 464mm vs global average of 860mm per annum; • The latest results from the IVRS indicate that the demand is currently exceeding the available supply; • RW’s abstraction licence will not be increased until the next Lesotho Highland Water Project Phase II is commissioned in 2025; • RW restricted to 1600 million m3/annum and is enforcing this restriction onto its water users through Project 1600; • CoE capped at 388 million m3/annum and the current water demand is 353 million m3/annum

  4. OBJECTIVES • All municipality within in the IVRS must target a zero or negative water demand growth rate • CoE targets a zero growth rate in system input volume for the next 6 year • Increase billed consumption by 15% for the next 6 year • Reduce NRW to 20% by 2025 • 20 % alternative water supply by 2030

  5. CoE WATER BALANCE APRIL 2019

  6. BACKGROUND: NON-REVENUE WATER (NRW) • World NRW average (2009/2010): 36.2% • National NRW average (2012/2013): 34.6% • Metros NRW average (2013/2014): 34.5% • CoE NRW figure (April 2019): 33.4%

  15. STAKEHOLDER ENGAGEMENT • “Stakeholders are people, groups, or institutions which are likely to be affected by a proposed intervention (either negatively or positively), or those which can affect the outcome of the intervention” Rietbergen-McCracken et al. (1998)

  16. STAKEHOLDER ENGAGEMENT • Primary stakeholders: Direct beneficiaries and concerned person • eg End users, etc. • Secondary stakeholders: Intermediaries in the process of delivering aid to primary stakeholders eg Professionals, schools and research institutions, NGO • Tertiary stakeholders: Decision, policy makers, • e.g. Politicians, senior civil servants, governmental bodies, etc.

  23. BARRIERS TO SUCCESSFUL NRW REDUCTION • Lack of political awareness • Inaccurate data • Lack of project Priotisation • Employee performance appraisals do not support NRW reduction

  24. TAKE HOME • Use the right KPI for NRW • High quality product pay off in the long term • Ensure the highest return on investment • Ongoing rehabilitation of water distribution network • Integrate NRW into day to day operation • Monitor and control leakage • Train technical staff • Benchmark for efficiency
