Johannesburg notes on water supply & purification
Bottled water and refill demand is strong in Soweto, Orange Farm and Alexandra, where outages leave households and spaza shops buying 18.9 litre bottles. Johannesburg Water supply interruptions also push schools in Diepkloof and Meadowlands towards tanks with bulk delivery. In the leafy north, Parktown and Houghton homes add under-counter filters to remove the chlorine taste. Factories along the Heidelberg Road corridor ask for commercial treatment plants and softening for boilers.
Drinking water in Johannesburg
Johannesburg sits far from any big river, so its tap water is pumped uphill from the Vaal system and the Lesotho Highlands scheme by Rand Water, then distributed by Johannesburg Water. Reservoirs and pump stations have faced maintenance shutdowns, burst mains and power interruptions, and parts of Soweto, Alexandra and the older northern suburbs often see low pressure or dry taps for a day or two. The water is moderately soft and tastes of chlorine in summer. Dispensers are common in Braamfontein and Marshalltown offices, Wynberg and City Deep warehouses, southern schools and taxi rank shops, where staff want a reliable drink when the municipal supply drops.

Who asks for UV water purification around Johannesburg, most often first:
- Offices and business parks: UV on the incoming line of a rural office or workshop with a tank or borehole supply
- Households: a small UV unit at the kitchen tap or after the tank for drinking water
- Factories, mines and building sites: UV on process or canteen water after sediment filtration, sized to the line flow
