Water supply & purification in Welkom: local notes
Welkom residents commonly rely on 18.9 litre refills and plastic tanks when the mains fail, and tanker operators supply clinics and school hostels. RO and under-counter filters help where taps run cloudy after repairs. Farms outside Hennenman and Allanridge often use boreholes, where testing for salts and bacteria should come before any treatment plant is quoted.
Drinking water in Welkom
Welkom was built for the goldfields, and its water network shows its age. Bulk water comes from the Vaal system through Sedibeng Water, then the Matjhabeng municipality distributes it over a wide, flat grid of streets and townships. Burst mains, reservoir problems and broken pumps have left parts of Thabong, Virginia and Odendaalsrus without water for long stretches. Taps may show discolouration after repairs. With mining decline, many offices have downsized, but schools, clinics, shopping centres, guesthouses and the remaining industrial sites still buy coolers, and households commonly stock bottles and tanks for outage days.

The requests we see from Welkom usually come from:
- Households: an under-sink RO unit with its own tap for drinking, cooking and the kettle
- Schools, crèches and colleges: an RO unit for staff and tuck shop use where tap water is hard
- Clinics, practices and care homes: an RO unit for drinking water and equipment rooms, serviced on a written schedule
