Abstract
Indirect recycling of storm water and treated wastewater for potable purposes has
formed an integral part of the Atlantis water resource management scheme for
the past 30 years. This augments the limited natural groundwater supplies along
the semiarid west coast north of Cape Town. Initially all wastewater was
recycled including an industrial component until water quality considerations
dictated otherwise. The paper investigates various aspects of the longer term
recharge of tertiary treated wastewater and urban runoff using \“indicator”
determinands. It also describes the analytical results for trace organic compounds
and pharmaceuticals. The analysis confirms the role of the subsurface passage as
a barrier reducing the health risk for potable reuse.
Keywords: managed aquifer recharge, artificial recharge, unconfined aquifer,
basin recharge, wastewater recycling, urban storm water, salinity, indicator
organisms, South Africa.
