  1. Rand Water’s Approach with Municipalities & Government Disciplines to address and Improve Wastewater Services Presented by Wiseman Sibiya

  2. PRESENTATION OUTLINE • Introduction • Rand Water’s Approach • Milestone Achieved • Challenges encountered • Lessons learned • Conclusion • Q & A

  3. INTRODUCTION Recent assessment of WWTWs conducted by Rand Water in Gauteng, Free State and Mpumalanga revealed that: • Municipalities are facing serious change on O&M of WWTW and related sanitation systems. • Ageing infrastructure • Lack of technical skills relevant to wastewater services • Inadequate funding/budgeting to run these systems • Institutional arrangements

  4. …Contd Rand Water is state owned enterprise and bide by Water Services Act 108 of 1997 to provide: • Management services • Training and other support services( including sanitation) to Water Service Institutions (WSI) • Supply treated/non-potable water to end users • Catchment management to or on behalf of Water authorities

  5. …Contd According to DWA`s “First Order Assessment Report conducted in May 2009 and 2009 Green Drop Report : • Nearly half of the 852 wastewater treatment works around the country were not in a state to be assessed. • 203 wastewater treatment plants scored “better than 50% • 32 wastewater treatment plants (3.8%) received Green Drop status. • The poor performance is mainly caused by design limitations, lack of adequate funding for operation and maintenance, skills shortage including insufficient attention given to maintenance by municipalities.

  6. ….Contnd • DWS, Water & Sanitation Sectors’ Goal: to meet the needs of the people in terms of water services provision, to promote sanitation services and to protect the water resources.

  7. RAND WATER’S APPROACH • Assist WSA by conducting detailed assessment on WWTWs and sewage pumpstations • Compiled assessment report with recommendations and present it to the WSA • Assessment covers among others; process technology installed, design capacity vs operating capacity, HR matters, maintenance, budget, OHSA compliance, etc. • Enter to partnership with WSAs through: • Public-public Partnership

  8. RAND WATER’S APPROACH …Contd • Memorandum of Understandings • Co-operate Agreements • Institutional Capacity Enhancement

  9. 1. PROJECT DESCRIPTION The Employer’s objective is to upgrade the Sebokeng Waste Water Treatment Works by a 50Mℓ/day module.

PROJECT SCOPE • SRSS scope consists of: • Stage 1 (Technical Feasibility Study, Land Procurement and Institutional Arrangement) • Stage 2 (Design and construction for the Sedibeng Scheme and the implementation of Technical Feasibility Study outcomes)

  12. ….SRSS continues 3. PROGRAM Project Commenced: 10 February 2014 Completion Date (Short Team Implementation Phase) 14 December 2018 4. SOCIO-ECONOMIC DEVELOPMENT • The Socio-Economic Study is 90% complete. • There is no local labour involved because the project is still at professional services stage.

  13. WRSS 1. PROJECT DESCRIPTION The implementation of Westonaria Regional Sanitation Scheme (WRSS) located in Rand west Local Municipality under the jurisdiction of West Rand District Municipality. 2. PROJECT SCOPE • Construction of an New 20Ml/day Zuurbekom Wastewater Treatment Works 20Ml/day is part of the Westonaria Regional Sanitation Scheme Rand • Engineering Designs Services for Bulk Water & Sanitation Service at Syferfontein Development • Construction of Westonaria Pump Station & Associated Infrastructure 3. PROGRAM Construction Commence: All three projects are currently at evaluation stage and appointment to be concluded in March/April 2017 Commencement is subject to issuing of Record of Decision by GDARD for Zuurbekom WWTW and Mohlakeng Pump station. 4. PHYSICAL PROGRESS • EIA: • Draft EIA report for Zuurbekom to be submitted to GDARD by the 17th February 2017 • Final EIA report for Mohlakeng Pump Station was submitted to GDARD on the 25th August 2016 • WULA: • Submitted to DWS in 2016 and not issued • All tenders are currently at evaluation stage

  14. ..Contd 5. CHALLENGES • Pressure to obtain Record of Decision from GDARD. Targeted obtain approval by GDARD in the next 3 months. • DWS to issue WULA for Zuurbekom WWTW and Mohlakeng Pump Station 6.SOCIO-ECONOMIC DEVELOPMENT • The project estimated to employs about 100 locals, the process shall be done in phases as soon as main contractor have been appointed. • Male = 58 (estimated from total) • Female = 42 (estimated from total) • Total amount of money required to pay laborers and Subcontracts will be determined as soon as the construction contractor have been appointed.
