Background JW is responsible mainly for the following functions: Plan and provide new infrastructure to cope with demand and growth of the city Facilitate system development for new township developments Project manage the implementation of new capital projects Manage water conservation and demand management within the City Long term planning is reflected in the Master Plan. Maintenance and operate existing infrastructure in providing water and sanitation services.
Planning Framework National Development Plan Provincial Growth & Development Strategy CoJ 2040 Growth & development Plan State of the City – spatial, demographics Strategic outcomes – CoJ 2040 Strategic projects – Inner City, Mining belt etc Institutional framework Participating planning Key deliverables
Master Planning Objectives The Master Plan reflects the continuous analysis of current usage of the water and sanitation infrastructure to identify shortcomings to be addressed The Master Plan is updated quarterly to reflect new influences from both the private and public sector as well as political decisions. It analyses future requirements from the Spatial Development Framework documents It extrapolates trends of growth to estimate future needs It examines the effect of proposed new developments to ensure sufficient capacity in the infrastructure The cost of proposed upgrades and extensions are calculated for budget purposes It schedules proposed upgrades and extensions to the infrastructure so that budget and planning can be addressed timeously. The 10 Year Scheduling reflects the near future Master Plan

COMPREHENSIVE INFRASTRUCTURE PLANS Capital Budget Forecast – Water (R 2009 values)
Condition Grading Attention paid to assets falling in the poor-very poor condition (these form condition backlog) - for inclusion in the short-medium term capital investment program.
RUL Grading Attention paid to assets falling in the 0-5 years RUL range for inclusion in the short-medium term capital investment program. 18

RUL Profile JW has Asset Management Plan – Driver of Infrastructure Capital requirements Total Assets Value – R 55 billion (CRC) Critical Assets that requires replacement/renewal – R 12.65 billion (Over next ten year period) This equate to requirement of R1.265 billion per year over the next 10 years for capital replacement/renewal Note: This requirement excludes JW Expansions and Upgrades of Infrastructure needs Asset Sub-Categories Remaining Useful Life (Years) (CRC Amount – R (Million) 0-5 6-10 11-15 16-20 More than 20 Water Supply Network 3 747 1 706 2 683 478 11 482 Wastewater Supply Network 2 770 1 625 2 601 3 191 13 664 Wastewater Treatment Works 1 161 1 641 183 1 417 1 334 Total 7 678 4 972 5 467 5 086 26 481 % Composition 15% 10% 11% 53%
Conclusion The Master Plan for future upgrade and extension of water and sanitation services is in place ensuring timely scheduling of projects within the constraints of the budget. The highest priority upgrade and extension projects for both water and sanitation are already underway/in construction. Limited funding is affecting the Projects Implementation and progress. Additional grant funding would enable acceleration.
