WASTEWATER RISK ABATEMENT PLAN Progress Report on the W2RAP Process WASTEWATER RISK ABATEMENT PLAN

PROGRESS REPORTED IN CONTEXT OF: W2RAP Guideline for South Africa Why do SA need a W2RAP ? What is a W2RAP ? W2RAP Guideline in SA municipal sector Development of a Guideline for SA municipal sector Test / apply W2RAP process to enhance wastewater services Roll out of W2RAP through risk-based regulation within a quaternary catchment context 2 examples (Berg River, Hartbeespoortdam) Replication elsewhere in SA 4. Benefit and Way forward 2

Why SA needs a W2RAP process? Wastewater collection & treatment systems operate 24 hours, 7 days, 365 days of the year. Limited control over the quantity and quality of the raw wastewater. These municipal assets operate in aggressive and corrosive environments, with aging infrastructure. The W2RAP process is to document risks and to establish control measures to mitigate/manage any operation or situation which will cause harm to public and environmental health. To mitigate potential risks = W2RAP as primary risk management tool W2RAP encompasses all steps in the wastewater value chain: production of sewage transport and treatment discharge or reuse of final effluent or sludge. 3

WHAT IS A W2RAP? There are many risk-based applications and multi-barrier approaches in world W2RAP is however the 1st of its kind globally, SA’s own initiative Direct link between: Water Safety Plan (WHO initiative) = drinking water and W2RAP = wastewater Where ‘wastewater’ is one of the key risks on drinking water side The W2RAP shows the link to the Blue- and Green Drop regulatory programmes in South Africa. Therefore, it closes the gap between drinking water assurance and wastewater quality - BOTH critical elements of SA water security 4

WHAT IS A W2RAP? (2) The W2RAP is a process to manage overall risk at Critical Control Points (such as pumpstations, inlet works, disinfection of final effluent) or across the entire value chain of sanitation services. The risk assessment process assist municipalities to identify various types of risks (e.g. electricity interruptions, sludge dam wall rupture, breakdown in recycle pumps, lack of technical staff, funds, vandalism, etc), and to…. Formulate specific actions to be taken at different levels of the municipal business, namely: Environmental, Financial, Operational and Institutional...” 5

STATUS OF W2RAP Guideline: Development completed (January 2011) Peer reviewed via the Water Research Commission appointed team of specialists (November 2010 - March 2011) Print & publication (May 2011) Release at Municipal Water Quality Conference (26 June 2011) – free distribution to all users in SA Development included testing of the ‘prototype’ by 4 municipalities to see if applicable, practical and value-added to enhance wastewater service in local government City of Cape Town eThekwini Steve Tshwete Nelson Mandela Bay 6

ROLL OUT OF W2RAP FOR RISK-BASED REGULATION Department of Water Affairs apply the W2RAP as a targeted regulatory tool to facilitate turnaround and continued improvement, based on risk-priorities – constant movement & measurement from higher risk to lower risk positions….. Two Catchment-based targeted initiatives to reduce risks: Berg River: why? Economic, health, public outcry, agriculture, business, academic’s pressure Hartbeespoort: why? Environment, public, down stream water users Both cases, if successful, can be replicated elsewhere in SA to bring same benefit to previously ‘unresolved’ issues 8

PROGRESS - W2RAP as RISK-BASED REGULATION (1) Berg River Catchment: Progress Meeting held on 24 May 2011 – all 6 municipalities attended that discharge into the Berg River All 6 WSAs presented their W2RAPs as well as the actions already underway to reduce risk (supported by adequate resources) WSAs = Berg Rivier, Drakenstein, Witzenberg, Stellenbosch, Swartland and Saldanha Bay Local Municipalities 100% positive response Highlight = Witzenberg and Drakenstein LMs included Councilors and financial staff in their W2RAPs as part of addressing financial sustainability of wastewater services (a key risk…) 9

PROGRESS - W2RAP as RISK-BASED REGULATION (2) Hartbeespoort Dam Catchment: Meeting on 26 May 2011 with all 6 municipalities who discharge to Hartbeespoortdam All 6 WSAs presented their W2RAPs and plans forward WSAs = Tshwane, Ekurhuleni, City of Joburg, Mogale City, Madibeng, Randfontein 100% positive in all 6 cases Highlights: Ekurhuleni introduced a means of identifying and measuring residual risk; going beyond the current W2RAP thinking. City of Joburg implementing a target of 0.1mg/l Phosphates instead of the 0.9mg/l set by their lsince conditions. (Sense of Responsibility) 10

Benefit: Municipalities use W2RAP as focused tool to prioritise scarce resources where risk is highest to public health, services, and environment It bridge communication and planning barriers between technical/engineering officials and financial staff Whilst providing political principals with relevant and current information and relevant/adequate PLANS to inform decision making Instilling Wastewater service management based on a sense of Responsibility; not only managing wastewater service with the objective of adhering to the minimum requirements. The quaternary Catchment based approach creates the opportunity for cross-pollination between municipalities working towards the same objective of improving water resource quality. 11

WAY FORWARD To expand the (Harties/Berg) Targeted Risk-based approach in other areas such as Zeerust (North West) and in Eastern Mpumalanga (Requests from Sector partners in these areas) Green Drop 2012 will require WSAs to present their W2RAPs and implementation proof thereof Strengthen regulation via combination of incentive- and risk-based regulation for maximum impact Compliance & Performance 12
