International standards have classified South Africa as a water-stressed country with an average annual rainfall of 464mm, which is about half of the world’s average rainfall (860mm). Only one third of South Africa’s major rivers are in average condition, with more than 60% of rivers being overexploited.The recent drought pattern highlights increasing demands, which require new and innovative solutions to the water supply problem. The Department of Water and Sanitation (DWS) has thus identified the reclamation of wastewater as an essential strategy. Umgeni Water and the Water and Sanitation Department of the eThekwini Municipality (EWS) has initiated a few wastewater reuse projects at the demonstration level scale.
Aims:To identify the social aspects of wastewater reuse in Durban and develop strategic recommendations for public acceptance of wastewater reuse.
Objectives:
1. To evaluate significant factors affecting public perception and acceptability of recycled wastewater in Durban.
The project will investigate the underlining factors that can be a potential barrier in the successful implementation of wastewater reuse. A framework of strategic recommendations will be developed from the findings that can help local water service providers to effectively communicate with the public regarding wastewater reuse. The study outcomes and strategy can be implemented at the local level, as well as extended lessons can be supportive at national level to establish wastewater reuse schemes in the country. Holistically, the study will aid in the planning and implementation of the wastewater reuse as an alternative water resource in South Africa.
Wastewater reuse can be an alternative strategy for augmentation of current water supplies. An option of treating wastewater up to the quality of potable use is technically possible, however, public acceptance can cause the failure of this project. Recycling is the future trend in water research, which is multi- dimensional, ranging from technical feasibility to behavioural change among the public. With this project, public acceptance of recycled wastewater is sure to improve.
