DISRUPTION OF WATER SUPPLY ON THE 53 PIPELINE FROM DV HARRIS WATER WORKS DUE TO REPAIRS

MEDIA AND PUBLIC NOTICE

Wednesday, 2 October 2024

uMngeni-uThukela Water has detected a leak in the 53 pipeline which supplies water from the DV Harris Water Works to reservoirs in Umlaas Road.

This has necessitated an immediate shut of the pipeline in order for the damage to be assessed and repaired.

The pipeline supplies approximately 30 mega litres of water per day to parts of the uMgungundlovu District and the eThekwini Metro.

The following areas may have their water supply affected while repairs are in progress:

  • Umbumbulu
  • Eston
  • Mid-illovo
  • Camperdown
  • Parts of the Outer West of eThekwini

We apologise for any disruption that will be caused during the repair work. We also urge the public to continue to use water sparingly.

Improvements noted in treated water volumes at the Durban Heights Water Works after decrease in algae

MEDIA AND PUBLIC STATEMENT
Monday, 26 August 2024

uMngeni-uThukela Water’s efforts to reduce the amount of algae in the water being treated at the Durban Heights Water Works have begun bearing fruit. Over the weekend, uMngeni-uThukela Water was able to increase its production volumes from 500 mega litres to 580 mega litres at the Durban Heights Water Works. This water is supplied to parts of the north and south of the eThekwini Municipality.

The increased supply is due to uMngeni-uThukela Water’s ongoing efforts which include the optimisation of its treatment processes to rid the water of excess algae as well as using advanced chemical treatment methods to unclog its filters. Our water quality monitoring has also been increased in order to detect and act against the presence of algae in raw water from the Albert Falls-Nagle Dam system.

While the situation has not yet normalised, there are promising signs of a decrease in the algal count in water from the Albert Falls-Nagle Dam system. uMngeni-uThukela Water continues to monitor the raw water quality and we anticipate that the problem will be resolved once the algal count from Albert Falls-Nagle Dam subsides.

Over the past two weeks, there has been a substantial increase of volumes of algae in water received from the Albert Falls-Nagle Dam system. While the increased presence of algae is not common in the colder winter season, there has been an increased algal count at the Durban Heights Water Works which has led to the clogging of filters.

We apologise for the inconvenience caused.

Media And Public Statement: Temporary reduction in treated water volumes at the Durban Heights Water Works due to algae growth

Issued by: Office of the Chief Executive, Marketing, Communications and Stakeholder Management Unit

 Thursday, 22 August 2024

uMngeni-uThukela Water’s Durban Heights Water Treatment Works is currently treating reduced volumes of water due to filters being clogged by large volumes of algae. This has affected the volumes of treated water being supplied to some parts of the north and south of the eThekwini Municipality.

Over the past two weeks, there has been a substantial increase of volumes of algae in water received from the Albert Falls-Nagle Dam system.  While the increased presence of algae is not common in the colder winter season, there has been an increased algal count at the Durban Heights Water Works which has led to the clogging of filters.

Due to this increased presence of algae in raw water, the Durban Heights Water Treatment is currently unable to treat the full amounts of raw water it normally supplies to its customers.

uMngeni-uThukela Water is currently implementing a number of interventions including optimising its water treatment processes and using advanced chemical treatment methods to unclog its filters.  We are also undertaking ongoing water quality and quantity monitoring to ensure the production of safe drinking water.

We apologise for the inconvenience caused.

El Niño Update – June 2024

As of mid-June 2024, oceanic and atmospheric indicators in the central-eastern Pacific Ocean align with neutral El Niño Southern Oscillation (ENSO) conditions, while diminishing El Niño conditions remain in the western Pacific. Predictions from various climate models suggest that the ENSO-neutral conditions will persist for the remainder of the Southern Hemisphere winter season. In addition, all climate model forecasts show potential La Niña conditions from the spring season. An important observation is that sea surface temperatures in the Southern Hemisphere have been cooling since December 2023. However, there remains great uncertainty regarding the onset, as well as the probability of La Nina conditions amongst the different models. For example, the NOAA CPC models show a 75% chance for La Niña conditions to persist during the August to October period, while the IRI shows 45% likelihood for La Nina conditions during this period (Figure 1). These differences are due to the relatively low skill of seasonal forecast models during this time of the year. Therefore, these probabilities should be used with caution.

Figure 1: ENSO Probabilities based on CPC and IRI models.

Due to the relatively good rainfall received in uMngeni-uThukela Water’s area of operation during the rainfall season, most UUW-operated dams have remained in relatively high storage levels during May and June 2024. For example, the storage trajectories of the Mgeni System are shown in Figure 2 below.

Figure 2: Historical storage trajectories for the Mgeni System.

Due to the high storage levels observed in most UUW-operated dams, the risk of non-supply remains relatively low for UUW’s customers in the short to medium-term. However, it is important for water users to implement demand-side water resources management strategies such as reusing water for non-potable purposes and fixing household leaks. uMngeni-uThukela Water will continue to monitor the ENSO signal and an update will be issued at the onset of the spring season.

Lowering of Mvutshane Dam to allow for rehabilitation work

The Mvutshane Dam which supplies water to the Maphumulo Local Municipality under the ILembe District Municipality will undergo a phased lowering from its current 63, 7% level to 40% with effect from 15 July until 15 August 2024.

This is to allow for the rehabilitation and strengthening of the dam embankment against erosion. This dam will be maintained at the 40% level until 10 September 2024 when the rehabilitation work is expected to be completed.

During this time, uMngeni-uThukela Water will continue to treat and supply normal volumes of water and no water disruptions are therefore anticipated.
