Joburg Water Alert: 72-Hour Throttling Starts Tonight – Schedules, Tips & Helplines
Attention, Johannesburg residents! Starting tonight on November 1, 2025, water throttling will affect several suburbs due to Rand Water’s supply constraints. This involves reduced pressure, leading to low flow or interruptions in some areas. The issue stems from high demand, infrastructure leaks, and ongoing maintenance in the City of Johannesburg.
With protests today calling for solutions, many are preparing for disruptions. Stay informed with our suburb-specific schedules, practical JoJo tank tips, and essential contacts to manage through this period. Keep hydrated, Joburg!
Why Joburg’s Water Supply is Strained
Rand Water, the primary supplier for Gauteng, is facing significant challenges. Issues like leaking reservoirs, power disruptions at pump stations, and illegal connections have reduced supply by up to 40% recently. Johannesburg Water (JW) is implementing throttling—reducing pressure in high-usage areas to conserve resources.
Tonight’s throttling in Zondi and Power Park begins a 72-hour period of rotating restrictions across suburbs. Anticipate low pressure from 8pm to 6am, with possible complete interruptions in some spots. This follows patterns from previous restrictions, contributing to broader supply issues.
Suburb Throttling Schedule: Who’s Affected
Based on JW’s updates, here’s the schedule for the coming days. Prepare your storage tanks if your area is listed:
| Date | Affected Suburbs | Expected Impact |
| 1-2 Nov 2025 (Starts Tonight) | Zondi, Power Park | Low/No Pressure 20:00-06:00 |
| 7-8 Nov 2025 | Diepsloot, Jabulani, Aeroton, Doornkop North, Roodepoort Deep | Intermittent Supply |
| Ongoing (Check Daily) | Kaalfontein, Ivory Park, Meadowlands, Diepkloof Ext, Cosmo City | Variable Restrictions |
Pro Tip: Follow @JHBWater for live updates. Unplanned issues, such as the recent Illovo Pump Station outage, can occur unexpectedly.
JoJo Tank Tips: Maximize Your Supply
JoJo tanks are essential during shortages, but proper management is key. Here are effective tips to optimize your water storage:
- Elevate for Better Flow: Raise your JoJo 2-3 meters on a stable base for gravity-assisted pressure.
- Install a Filter: Add a 50-micron inline filter at the inlet to avoid sediment buildup—lasts about 6 months for around R200.
- Harvest Rainwater: Link gutters to a secondary inlet for natural refills during rains.
- Auto-Float System: Use a float switch to prevent overflows and get low-level alerts (DIY kits around R500).
- Water Treatment: Aerate with air stones and add 1ppm chlorine to extend freshness without boiling.
- Community Sharing: Create a neighborhood group for coordinating tanker deliveries—one truck can support multiple homes.
Bonus: Insulate your tank with foam to reduce algae growth in the heat. A full 10,000L tank can sustain a family of four for five days at 20L per person daily.
Water Conservation Tips
- Opt for bucket baths over showers (saves 100L each).
- Use low-flow methods: Place bricks in the toilet cistern (20% savings).
- Check for leaks: Add food coloring to the tank to detect drips.

Protesters took to the streets today, highlighting frustrations with JW and Rand Water over persistent outages. These contacts provide immediate assistance while solutions are pursued.
Long-Term Strategies: Beyond the Current Restrictions
This challenge is ongoing, rooted in aging infrastructure (with leakage rates around one-third), environmental factors like acid mine drainage, and rapid population increases. Rand Water’s Eikenhof and Zwartkopjes plants are operating above capacity.
Consider lasting solutions: Install greywater systems (R5,000 setup, recoups in 6 months), assess boreholes, or join community drilling initiatives. Use apps like JW’s fault reporter for quicker fixes.
Joburg has overcome tough times before. Prepare, conserve, and advocate for improvements. Water is essential—let’s safeguard it.
