Overview
- Combined storage across the Western Cape Water Supply System has slipped to about 48.8% to 49.2%, continuing a steady week‑on‑week decline from just above half.
- The City has kept an early drought caution in place and says the window to avoid water restrictions later this year is narrowing.
- Theewaterskloof, the system’s largest dam and source of about 51% of provincial supply, is around 47% and remains the main pressure point.
- High demand of roughly 1 billion litres a day, average use near 175 litres per person, sustained heat, weak inflows, leaks, and aging pipes are speeding the drawdown.
- City modelling indicates levels could approach 40% by May if demand stays high and winter rain is only average, which would strain households, farms, and towns tied into the integrated regional system.
