Source of Water in Johannesburg, South Africa

Johannesburg’s tap water primarily comes from surface water sources, including the Vaal River system and the Lesotho Highlands Water Project.

Additional supply comes from local dams such as the Vaal Dam and the Roodeplaat Dam, which store and regulate water for treatment.

Groundwater supplements the supply but constitutes a small proportion compared to surface water sources, ensuring a reliable and consistent water supply to the city.

Johannesburg Drinking Fountains

Public drinking fountains in Johannesburg are connected to treated municipal water, generally making them safe under normal maintenance conditions.

However, fountains may pose health risks if poorly maintained, contaminated, or if structural damage allows bacterial growth or pollutants.

For safety, users should observe cleanliness and avoid fountains with visible damage or dirt. Bottled or boiled water is a safer alternative if unsure.
