With an increasingly urbanised population, further study was necessary to determine if water could be used more efficiently by applying efficient tariff structures in combination with decision support tools in the form of models. This paper highlighted challenges towards establishing a sustainable surface raw water tariff structure. Limitations of using the pollute-pays principle for setting a surface raw water tariff structure within a highly urbanised environment were noted. A tariff structure in the Upper and Middle Vaal Water management Areas which are part of the Vaal basin in South Africa was shown to promote inequity such that a downstream user paid more for using more polluted water. Recommendations specific to the Vaal basin included adopting a user-pays principle and also use of a model that incorporated variability in surface raw water quality for tariff setting and also for purposes of predicting potable water treatment costs.
