Water is becoming one of the fastest rising and least predictable costs for South African businesses. Many municipalities implemented further water and sanitation tariff increases from 1 July 2026, the Department of Water and Sanitation is consulting on raw water use charges, and supply interruptions remain a reality in several regions.
Why water risk is a business risk
A water outage can stop production, close a hotel kitchen or force a building to send tenants home. Rising tariffs, effluent charges and sanitation costs add up quickly, and customers and investors increasingly ask how you manage water.
Start with a water balance
You cannot manage what you do not measure. A water balance maps every flow on your site, from municipal intake and boreholes to processes, cooling, ablutions, irrigation and effluent. It usually reveals water that nobody can account for, which is often leaks.
Quick wins
- Check night and weekend flow on the main meter to find hidden leaks
- Install sub meters on the biggest users so you can see where water goes
- Fit efficient taps, showerheads and urinals in ablution facilities
- Optimise cooling towers and boilers, which are often large hidden users
- Repair steam traps and recover condensate
Bigger opportunities
- Reuse treated process water or greywater for cleaning, cooling or irrigation
- Harvest rainwater from large roof areas
- Reduce effluent volumes and strength to cut trade effluent charges
- Add storage and a contingency plan to keep operating during supply interruptions
