Appointment of new Chief Executive for uMngeni-uThukela Water

Sandile Mkhize returns to KZN to share experience and knowledge:
The new CE of uMngeni-uThukela Water is living proof that, when a village raises a child, the adult returns the blessings many-fold. In taking up the post of Chief Executive of uMngeni-uThukela Water, Sandile Mkhize is returning home to give the province of KZN the benefit of the wealth of knowledge and experience he has gained in the environmental and water services sector since he first studied, and later taught at the University of KwaZulu-Natal (UKZN) in the 1990s.

Born in the township of KwaMakhutha in Durban, Sandile has always believed in the value of science and education to contribute to society. After completing a BSc in Chemistry and Microbiology at UKZN in 1996, Sandile added a Bachelor of Technology in Biotechnology in 1997 as well as a Master’s degree in Environmental Biotechnology from the Durban University of Technology (DUT).

All his knowledge was put to effective use when the Department of Water Affairs and Forestry provided him an opportunity in the Public Service sector when he was appointed as a Water Pollution Control Officer in 2000. A position as Senior Environmental Officer in the Gauteng Provincial Department of Environmental Affairs followed soon thereafter.

In 2002 Mkhize joined the Development Bank of Southern Africa as an Environmental Analyst. As Sandile is always eager to learn as much as possible, further studying ensued with a focus on business administration skills. After completing the Management Advanced Programme at the University of the Witwatersrand in 2006, Sandile successfully pursed his MBA at the Milpark Business School.

A move to the private sector followed in 2007 when Sandile joined Chevron, owners of the Caltex fuel brand in South Africa. There, he could merge his environmental and business acumen in his role as the company’s site remediation specialist. This position involved extensive travel throughout Africa and this experience helped Mkhize to climb the corporate ladder and gain insights into the unique challenges faced in the water and environmental spheres on the continent.

Further continental experience was added during a period with AngoGold Ashanti where his management and administration skills were honed in roles involving project management while taking charge of the environmental department of a large mine in Tanzania. As is common with many in the mining sector, Sandile fell victim to the raft of mergers, right-sizing and other rationalisation measures in the sector and experienced the disruption facing retrenchment in 2013.


Never one to rest on his laurels, however, he turned this experience into a positive learning opportunity and spent some time as an environmental and planning consultant to entities in the water services sector.

Unsurprisingly, Mkhize’s unique blend of skills and experience was soon recognised and he was appointed as the General Manager of Magalies Water in 2014. This position was soon followed by his appointment as Chief Operating Officer of the entity.

In 2016, he was appointed as the Chief Executive Officer of Magalies Water. During his tenure at this State-Owned Entity, he was instrumental in ensuring that the utility delivered on its mandate in the most efficient manner possible. Whilst managing his day-to-day responsibilities, he also pursued a Senior Management Program at Havard Business School in 2017.

Highlights of his tenure at the entity include the growth of its asset base from R1.2 billion to its current R4.12 billion value while achieving benchmarks of above 90% against the requirements of its shareholder compact. In addition, Mkhize’s sound business administration skills and insistence on clean corporate governance standards, has seen the entity achieve annual clean audits from the Auditor General of the Republic of South Africa since 2019/20.

He steered the organisation through the reconfiguration of Magalies Water with Sedibeng Water in 2022. With his wealth of chemical, environmental and business knowledge and experience predominantly in the Water Sector, Sandile Mkhize’s is certain to ensure that uMngeniuThukela Water continues to deliver on its mission to improve water and sanitation services for all communities in Kwazulu-Natal.

MEDIA AND PUBLIC NOTICE: Interruption of Water Supply to Parts of the Ugu District After Storm Damage to Mthwalume Water Treatment Works

Monday, 15 January 2024

The heavy rains over the weekend have caused damage to the Mthwalume Raw Water Abstraction System which supplies water to the uMzumbe and uMdoni Local Municipalities under the Ugu District.
The temporary weir which draws water from the Mthwalume River was washed away and the Treatment Plant is no longer able to draw water for treatment due to the displacement of the raw water submersible pumps.
Extensive work is required to restore the system back into full operation. uMngeni-uThukela has deployed additional resources to speed up this recovery process.
We anticipate that the system will recover by Thursday, 18 January 2024.
The damage to the Mthwalume System has affected the supply of water to the following areas in the uMzumbe and uMdoni Local Municipalities: Elysum, Bazley, Ifafa, Koelwater, Sezela, Mthwalume Urban, Qoloqolo, Nomakhazana, Sibanini, Bhekulwandle, Mfazazana, Sihlonyaneni, 26, Arnold Lushaba Hospital, Nkambini, Bhunwini, Makhoso, Bangibizo, Dembese, Mathulini, Nyangwini and Mgangeni.

El Niño Update – December 2023

El Niño Update – December 2023

By Mlungisi Shabalala, 01 January 2024

The latest assessment of the El Niño Southern Oscillation (ENSO) signal shows that the key oceanic and atmospheric variables in the central-eastern equatorial Pacific Ocean remain consistent with the ongoing strong El Niño conditions. Almost all climate models suggest sustenance of the strong El Niño signal throughout the summer season into early autumn (see Australian Bureau of Meteorology and International Research Institute for Climate and Society for detailed information on climate models).

Based on the sea surface temperatures in the Pacific Ocean (ENSO zone of interest), the ongoing El Niño cycle may potentially be amongst the four strongest El Niño cycles on record. El Niño conditions typically result in below-normal rainfall in South Africa. However, the impact of the ongoing El Niño cycle on rainfall has, so far, been minimal.

During December 2023, uMngeni-uThukela Water’s area of operation received relatively normal to above-normal rainfall, as suggested by the October 2023 climate model predictions. As a result, most dams were above full supply capacity at the end of December 2023, similar to the end of December 2022.

Although most global climate models suggests that an El Niño cycle is currently underway and will be sustained throughout the summer season, the latest model predictions indicate a likelihood of above-average rainfall in the central and north-eastern parts of the country (including UUW’s operational area) throughout the summer season. However, stakeholders are encouraged to conserve water resources as we approach mid-summer, which is typically characterised by high temperatures. Water users are also encouraged to remain alert and follow weather updates (as well as warnings) from the South African Weather Service. uMngeni-uThukela Water will issue an update at the end of January 2024.

El Niño Update – November 2023

El Niño Update – November 2023

By Mlungisi Shabalala, 30 November 2023

uMngeni-uThukela Water (UUW) continues to monitor the El Niño Southern Oscillation (ENSO) signal and its potential impacts on water resources operated by UUW. The latest climate model updates indicate that the ENSO remains in an El Niño state (Australian Bureau of Meteorology; International Research Institute for Climate and Society). According to the International Research Institute for Climate and Society, the probability of the sustenance of El Niño conditions remains high (100%) throughout the summer season (DJF).

Due to the above-normal rainfall received in UUW’s area of operation during October 2023, most dams remain at a relatively high storage levels. However, it is important to note that, on 30th November 2023, most dams were at lower storage levels than compared to a similar time last year (see dams in the Mooi-Mgeni System in the table below).

 Spring Grove Dam 69 101
 Midmar Dam 79 99
 Albert Falls Dam 92 97
 Nagle Dam 86 98
 Inanda Dam 101 102

Although most global climate models suggests that an El Niño cycle is currently underway and will be sustained throughout the summer season, there is a significant level of uncertainty on the potential impact of the current El Niño state on South Africa’s rainfall. El Niño conditions typically result in below-normal rainfall in South Africa, however, the latest model predictions indicate a likelihood of above-average rainfall in the central and north-eastern parts of the country (including UUW’s operational area) throughout the summer season. The average air temperature, on the other hand, is expected to be above-normal for most parts of the country, a typical characteristic of El Niño conditions. High temperatures may result in high evaporation losses, posing a threat to water resources availability. Therefore, it is essential for water resource managers to closely monitor the status of water resources as El Niño conditions develop.

 

Water users are advised to practice water resources conservation measures such as reusing water for non-potable uses such as watering lawns and gardens. Stakeholders are also encouraged to follow uMngeni-uThukela Water on various social media platforms for water conservation tips. Lastly, water users are advised to remain alert and follow weather updates (as well as warnings) from the South African Weather Service. uMngeni-uThukela Water will issue an update at the end of December 2023.

El Niño Update – October 2023

By Mlungisi Shabalala, 31 October 2023

uMngeni-uThukela Water (UUW) continues to monitor the El Niño Southern Oscillation (ENSO) signal and the latest model updates indicate that the ENSO remains in an El Niño state (Australian Bureau of Meteorology; International Research Institute for Climate and Society).  According to the International Research Institute for Climate and Society, the probability of the sustenance of El Niño conditions remains high (100%) for the upcoming summer season.

Coastal areas receive heavy rainfall in October 2023

Most parts of uMngeni-uThukela Water’s operational area have received above-average rainfall during the month of October 2023. As a result, most UUW-operated dams remain in a relatively healthy status. It is important to note that, contrary to the characteristics of an El Niño cycle, the rainfall received in October 2023 has been relatively high, when compared to October 2022 (a La Niña year). This was due to the two cut-off low systems which brought heavy rainfall and cool temperatures along the coastal areas during the month of October. As a result, uMngeni-uThukela Water sites along the coastal belt received above-normal rainfall during October 2023, with the South Coast, North Coast and Mhlathuze areas receiving 331%, 212% and 551% of rainfall received during October 2022, respectively. Notably, Eshowe received 355 mm of rainfall during October 2023, a tenfold increase from the 30 mm received in October 2022. This uncharacteristically high rainfall received during October 2023 has improved the storage in most UUW-operated dams. As a result, the risk of non-supply remains low for most areas supplied by uMngeni-uThukela Water in the short-term.

 

Is this the end of El Niño?

Although most of uMngeni-uThukela’s area of operation has received above-average rainfall during October, climate models still suggest sustenance of El Niño conditions over the entire summer season. El Niño cycles are associated with dry and hot conditions, posing a risk to water resources availability. In addition, most dams situated in the coastal areas (where most rainfall was received during October) are relatively small and are characterised by rapid response to changes in rainfall patterns. Therefore, the predicted sustenance of El Niño conditions during the summer season poses a risk to the long-term availability of water resources in these dams.

Water users are advised to remain alert and follow weather updates (as well as warnings) from the South African Weather Service. In addition, stakeholders are encouraged to use water sparingly, in order to reduce pressure on our already-stressed water resources. uMngeni-uThukela Water will issue an update at the end of November 2023.

El Niño Update – September 2023

El Niño Update 

By Mlungisi Shabalala, 29 September 2023

uMngeni-uThukela Water continues to monitor the El Niño Southern Oscillation (ENSO) signal and, according to Australia’s Bureau of Meteorology, the ENSO is currently in an El Niño state. This is in line with the latest ENSO status and projections published by the International Research Institute for Climate and Society, which suggest a 100% likelihood of El Niño conditions throughout spring to mid-summer. El Niño is associated with dry and hot conditions, posing a risk to water resources availability. Therefore, efficient use and management of water resources is essential during El Niño cycles.

Most dams that are managed and operated by uMngeni-uThukela Water are currently in relatively acceptable levels. However, it is important to note that major dams such as Midmar, Inanda and Spring Grove Dams are at lower storage levels than compared with a similar time last year. Although the risk of non-supply remains low for most areas supplied by uMngeni-uThukela Water in the short-term, sustenance of El Niño conditions will significantly increase the risk of non-supply.

With climate models pointing towards the sustenance of El Niño conditions over the summer season with more confidence, stakeholders are advised to remain alert and follow weather updates (as well as warnings) from the South African Weather Service. Water users are encouraged to practice and promote water conservation measures such as reusing water for non-potable domestic activities, reporting and fixing water leaks, taking shorter showers, etc. uMngeni-uThukela Water will continue to monitor the weather and climate conditions, and provide updates on the situation as it unfolds. The next El Niño update will be issued at the end of October 2023.

El Niño Update – August 2023

El Niño Update 

By Mlungisi Shabalala, 31 August 2023

uMngeni-uThukela Water continues to monitor the El Niño Southern Oscillation (ENSO) signal. The latest ENSO status and projections published by the International Research Institute for Climate and Society on 10th August 2023 indicate a 100% likelihood of El Niño throughout the upcoming spring season. This strong El Niño signal is expected to be sustained to mid-summer. El Niño is associated with dry and hot conditions, posing a risk to water resources availability (see previous blogs here for a detailed explanation of the ENSO phenomenon).

Australia’s Beareu of Meteorology also monitors the ENSO status, through the use of four levels, namely, (i) Inactive, (ii) Watch, (ii) Alert and (iv) Active (El Niño/ La Niña). According to the latest assessment (15th August 2023), the ENSO outlook is currently on El Niño Alert level and El Niño conditions have resulted in 70% of the cases where the alert level was reached (ENSO Outlook – an alert system for the El Niño–Southern Oscillation (bom.gov.au). This information, combined with the IRI projections, indicates that there is a strong likelihood for the development of an El Niño cycle in the upcoming spring and summer seasons.

Commensurate with the relatively above-normal rainfall received in parts of KwaZulu-Natal during the end of the preceding summer season, most dams  have maintained relatively high storage levels as we approach the spring season. Therefore, the risk of non-supply for uMngeni-uThukela’s area of operation remains low for the remainder of 2023. However, climate models continue to predict a strong likelihood of a hot and dry summer (i.e. El Niño). Hot and dry conditions will have a direct impact on water resources availability through low recharge/rainfall and high evaporation losses in dams. It is recommended that stakeholders remain alert and contribute towards the protection and conservation of the already-stressed water resources. uMngeni-uThukela Water will issue an update at the end of September 2023.

STATEMENT: Heavy downpours cause damage to uMngeni-uThukela Water infrastructure

[vc_row][vc_column][vc_column_text][/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]

STATEMENT: Heavy downpours cause damage to uMngeni-uThukela Water infrastructure

Tuesday, 12 April 2022

Heavy rains over the past four (4) days have caused substantial damage to some of uMngeni-uThukela Water’s raw water abstraction and conveyance infrastructure in at least three regions. At this stage following early assessments, uMngeni-uThukela Water is able to report that two aqueducts, which convey raw water to the Durban Heights Water Treatment Works, broke through rock falls in the vicinity of Inanda. These aqueducts have since been taken out of use due to the risk they pose to property and people.

Other damage reported overnight (Tuesday) has confirmed that the river abstraction system in Mtwalume River (South Coast) is not functioning because of blockage caused by the flooded river. Further, abstraction from the Umzinto River Dam has reduced significantly due to high overflows, resulting in only 60% of potable water that is required being produced at the Umzinto Water Treatment.

In iLembe, potable water production at the Lower Thukela Bulk Water Supply Scheme has been reduced because of high turbidity in raw water and abstraction pumps continue to fail as a result of silt in the abstraction channels. The command reservoir levels are low and as a consequence of this, supply to KwaDukuza Central Business District, Darnall, Zamani and Zinkwazi has been interrupted.

Three of uMngeni-uThukela Water’s customers – eThekwini Metro, Ugu District Municipality and iLembe District Municipality – are  cautioned that potable water production by uMngeni-uThukela Water has been compromised, which will result in significant reduction in supply of drinking water. An appeal is, therefore, being made to these municipalities to please reduce demand in order for uMngeni-uThukela Water to try to effectively manage available water resources.

Durban Heights Water Treatment Plant: The two aqueducts that have been damaged in the rock fall are among four (4) aqueducts that convey water from Nagle Dam for treatment at the Durban Heights Water Treatment Plant. The consequence has been that the plant is currently receiving raw from only two of the functioning aqueducts. The plant, therefore, is only treating half of the amount of water it normally treats and supplies daily. Water treated at this plant is conveyed to eThekwini Water and Sanitation, which supplies consumers in the north, south, central and inner west regions of Durban.

The current potable water shortfall means that eThekwini Water and Sanitation is unable to meet the full requirements of consumers. Until the aqueducts are repaired and brought back into full functionality, a deficit in raw water supply will prevail. Similarly, reduced supply of bulk potable water will continue to prevail. The impact on consumers will be experienced in erratic supply, interruptions in supply or low pressure in taps.

South Coast System: Mtwalume. Apart from failure of the abstraction system, additional damage caused by localised flooding was loss of the standby backup submersible pumping system at the Mtwalume Water Treatment Plant. Due to the current situation, uMngeni-uThukela Water is unable to treat water at the plant for supply to Ugu District Municipality. This situation will unfortunately prevail until the level of the river subsides, thereby allowing asset management staff to reach the abstraction equipment for removal and repair. Restoration of the standby pumping system is being treated as a priority. Water treated at this plant is ultimately received by consumers in Mtwalume, Ifafa, Bazley, Sezela and surrounding areas.

South Coast System: Umzinto. Reduced production at the Umzinto Water Treatment Plant due to abstraction difficulties means that uMngeni-uThukela Water is unable to meet the full demand of Ugu District Municipality for supply to Umzinto, Park Rynie, Pennington, Kelso and Malangeni. Unfortunately this  production and supply deficit will continue until uMngeni-uThukela Water is able to abstract the full amount of raw water it requires.

The extent of damage reported in this communique is an early assessment provided by staff who work at the sites that operate the affected infrastructure. Persistent torrential rains and impassable access routes have made it impossible for staff of uMngeni-uThukela Water to reach critical and major infrastructure in order to conduct a comprehensive analysis. The scope of investigation will be extended once conditions improve. Based on the outcomes, a clearer picture will emerge of the magnitude of damage, what needs to be done to restore full functionality and how long this process is expected to take.

Additional information will be shared with customers and consumers as it becomes available in the days ahead.

uMngeni-uThukela Water provides an assurance to its customers and consumers that once conditions improve, there will be no delays in executing the required repair work so that full potable water production and supply are returned to normal.
