Upgrading and expanding existing water reticulation pipelines through Muizenberg to these areas is possible, but will be expensive and disruptive. Alternative sources of water were hence considered, including the construction of a dam at Brooklands above Simon’s Town and development of local groundwater resources. This paper describes the potential for developing groundwater resources to increase a secure supply of water to these areas. INTRODUCTION The area south of Clovelly – including Fish Hoek, Noordhoek, Simon’s Town, Scarborough and Kommetjie – currently obtains water from water resources above Simon’s Town (Lewis-Gay Dam, Kleinplaas Dam, and Rawson Dam) and via a pipeline running through Muizenberg and Kalk Bay. A dam site at Brooklands was identified some 30 years ago as a potential future source of water to augment existing supplies (Figure 1). In response to a land claim – parts of which would be flooded should the dam be built - the City of Cape Town investigated whether the Brooklands Dam site was still required. To be able to make an informed decision regarding the reservation of the land for construction of the Brooklands Dam at some point in the future, the City of Cape Town commissioned a study to investigate water resource and supply options for the area colloquially referred to as the Deep South.
