3 National Water Value Chain
Water Resources Purification Bulk Distribution Role Players: DWA Water Boards Municipalities Service Providers Waste Water Treatment Bulk Storage Waste Water Collection Reticulation Household/User

4 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.

5 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

6 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

7 Software systems used IMQS Modules (Infrastructure Management Query Station): Wadiso – Water Design Sewsan - Sewer Design Swift – Demand Projections (SAP billing information) and UAW Asset Register Pipe Replacement software Project Tracker– Capital projects (Link IDP Projects to physical location of Project & Linking to assets under construction and asset register) Township application tracking within Water and Sanitation PlantMan (Managing maintenance activities on Purification plants, pump-station etc.) Financial system – SAP Water and Sanitation Maintenance recording - SAP

8 Projects: Reservoir Storage
JW required additional storage of 140 cost of R 275 Million.

9 Projects: Bulk Pipelines
Condition Investigation of 750 cost of R 50 Million.

10 Projects: Bulk Pipelines Upgrades
Upgrade Water 230 km Bulk cost of R 450 Million.

11 Projects: Water pipe replacement
770 km Water pipelines cost of R 1,5 Billion.

12 Projects: Pressure Management
Reduction of Static Pressure and cost of R 130 Million.

13 Projects: Sewer Pipeline Replacement
Replace 700 km of sewer cost of R 1,5 Billion.

14 Projects: Sewer Outfalls Upgrades
Upgrade 26 km of Sewer cost of R 360 Million.

15 Projects: WWTW Upgrades
Upgrade 325 Ml of Sewer cost of R 4.8 Billion.

16 COMPREHENSIVE INFRASTRUCTURE PLANS
Capital Budget Forecast – Water (R 2009 values)

17 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.

18 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

20 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 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%

21 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.
