Wastewater risk abatement plan: A W2RAP guideline
Expanded Title:In South Africa, current problems associated with the operation, maintenance and management of wastewater treatment works are the biggest contributor to risks threatening public health and environmental integrity. Given that it is possible to produce treated wastewater of almost any quality, managing the associated risks is essential for good governance and long-term sustainability of the country’s water resources. W2RAP draws on many of the principles and concepts from other risk management approaches, in particular the Water Safety Plan, the multi-barrier approach and Hazard Analysis and Critical Control Points (HACCP). The W2RAP guideline is however, amongst the first world-wide initiatives that plans for and applies a risk-based approach to raise and sustain wastewater performance. The formulation of this guideline document builds on existing good practice in outlining a systematic and transparent approach to ensure consistent compliance and good practice to rendering wastewater services (reticulation, treatment and scientific services) along the value chain. Emphasis is on wastewater planning and management, not on testing, with documentation and communication being a key component of the process. The development of the W2RAP in South Africa was undertaken collectively by the Department of Water Affairs and the Water Research Commission, and the pilot trials have been undertaken by the City of Cape Town, Nelson Mandela Bay and eThekwini Municipality. The primary objectives of a W2RAP are: • To minimize contamination of the resource to which the treated effluent is returned to, • To reduce or remove contamination through the treatment processes and, • To prevent contamination during transport of wastewater, storage and disposal of sludge.
