Johannesburg Water: significant improvements over the last 24 hours

Johannesburg Water systems are performing much better this week after experiencing low water supply since last week and by Thursday, all the systems should be stabilised.

Overall, the reservoirs and towers have shown significant improvement over the last 24 hours and should be back to normal operations.

The Crown Gardens system has recovered fully compared to Tuesday. Parts of Robertsham, like the high-lying areas, are still experiencing low pressure, but as the system stabilises, the water supply will improve.

In the last 48 hours, the Commando system has been stable while enjoying an inflow of 2800 kilolitres per hour, which is an improvement from yesterday’s 2600 kilolitres. Inflow at the Crosby reservoir is sitting at 0.62m with healthy inflows at 580 litres per second. This is because of Rand Water’s Waterval 2 reservoir sitting at between 45 and 50%. The aim is to fill it up to 70%, which should assist the Crosby reservoir.

The Brixton reservoir is sitting at 2.6m, compared to Tuesday’s 2.2m, with 239 litres of inflow per second. The reservoir has been stable for over 24 hours and by 10am on Wednesday, it had been opened to 100% capacity. This will help Jan Hofmeyer, Vrededorp, Mayfair West and surrounding areas with improved water supply.

The Hursthill system is still critical and experiencing low levels, with Hursthill 1 sitting at 0.74m with better inflows of 149 litres per second compared to yesterday’s 121 litres per second. Hursthill 2 reservoir is sitting at 0.39m and is still experiencing low inflows with 105 litres per second. Historically, the Hursthill 2 reservoir inlet is lower than Hursthill 1, therefore there should be more inflow than Hursthill 1, which is currently not happening. Technical teams are investigating the cause behind this so that capacity can start building at the reservoirs. The aim is to fill the reservoirs to at least 1m – 1.5m storage capacity in both.

The Entity will continue supplying stationary and roaming tankers.
