Stellenbosch notes on water supply & purification
Bottled water and refills serve students and visitors, with depots in the Stellenbosch industrial area and Somerset West. Farms in the Jonkershoek valley and along the Eerste River use borehole water and often need sediment filters with UV disinfection after testing. Homes in older streets of Idas Valley and Die Boord tend to add under-counter filters, while larger estates consider commercial purification for cellars and guest lodges.
Drinking water in Stellenbosch
Stellenbosch relies on a mix of sources, including local dams in the mountains above town, the Eerste River catchment and bulk supply from larger systems feeding the Cape region, and the municipality has faced pressure from fast growth. The water is generally soft and tastes mild, but ageing pipes in older neighbourhoods like Cloetesville can affect clarity. Dispensers sit in university offices, Technopark labs, wine estates around Jonkershoek and Simonsberg, guesthouses, student digs in Die Boord, and schools in Kayamandi and Idas Valley, where many families also buy bottled water for drinking.

Typical reverse osmosis systems requests in the area come from:
- Offices and business parks: an RO unit on the kitchenette supply feeding the coffee machine and a dispenser
- Lodges, hotels, restaurants and events: an RO unit for ice, coffee and drinking water in a restaurant, guesthouse or lodge
- Schools, crèches and colleges: an RO unit for staff and tuck shop use where tap water is hard
