Why SA needs a W2RAP process? • Wastewater collection & treatment systems operate 24 hours, 7 days, 365 days of the year. • 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. • To prevent the current situation where WSAs are being misled to believe that wastewater challenges can only be addressed by means of intensive capital investment
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
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...”
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
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.
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 To further the endeavour to facilitate improvement in wastewater management by means of innovative regulatory options.
