HOME > ENVIRONMENT STABILITY
The environment constantly undergoes multiple changes, changes that are occurring over different temporal and spatial scales. As a result, it is vital that natural resources are managed in a sustainable manner. Adequate supplies of raw water resources are paramount to uMngeni-uThukela Water, which together with reliable sources of energy, water treatment chemicals and other resources are crucial for sustainability of the water business.
The entity, therefore, is steadfast in protecting, conserving and using and sustaining these resources efficiently.
Environmental management programmes and plans are embedded in all components of the water business lifecycle, namely, during planning, construction, operation and decommissioning. UMngeni-uThukela Water has classified its environmental management programmes as Corporate,
Operational or Integrated Environmental Management:
uMngeni-uThukela Water, as a public water services entity in South Africa, complies with all mandatory environmental disclosure requirements. Notwithstanding this, the entity continues to improve alignment of environmental indicators with other national and internationally accepted indicator disclosure requirements, including the Global Reporting Initiative (GRI)
and King IV Report on Corporate Governance, in terms of materiality and relevance. Relevant aspects include materials, including chemicals and water resources, energy efficiency, greenhouse gas emissions, carbon footprint mapping, biodiversity and waste management.
In the reporting period, progress was made with the following water resource dam developments:
uMngeni uThukela Water is piloting a reuse plant at its Darvill Wastewater Treatment Works. The 2 Ml/d direct reuse demonstration plant comprises a conventional water treatment works to provide high-pressure wash water followed by an advanced treatment process plant. The plant is to be used for evaluating the effectiveness of reuse processes and for demonstration to communities on the benefits of wastewater reuse to applicable potable water standards.
The status of raw water quality per resource is shown in Table 11.1 and Figure 11.2. Water quality risks in uMngeni-uThukela Water supply catchments arise from factors including: eutrophication (nutrient enrichment and its associated threats including algal blooms, taste and odours and aquatic weed infestations), faecal contamination and associated pathogen risks, suspended solids and chemical constituents (including iron and manganese). This impacts on treatability, chemical usage and other cost implications, and may contribute to final water non-compliance with the South African National Standard Drinking Water specifi cation (SANS 241: 2015).
Source and raw water quality monitoring is undertaken to assess and mitigate treatability risks, optimise raw water quality and provide early warning of adverse raw water quality that can be expected at the water treatment works.
Catchment water quality management plans include:
The Department of Water and Sanitation (DWS), as the custodian of South Africa’s water resources, is kept informed of the quality, trends and potential risks associated with raw water resources.
In response to the water quality issues highlighted under the raw water quality section, the table blow, lists the unterventions that are currently being implemented to improve the raw water quality at catchment level.
uMngeni-uThukela Water strives to use the water abstracted from resources assiduously. Water balancing and water loss management measures are in place per treatment system. Overall, water loss levels have been maintained below the entity’s target level of 5% over the years. Water loss trends are shown below:
Water is the most significant input material for uMngeni-uThukela Water, as described in the previous section, followed by energy, which is discussed below. In addition, uMngeni-uThukela Water has a high reliance on water treatment chemical resources and is, therefore, committed to improving the usage efficiency thereof.
The chemical usage trend for the past five years presented in Figure 11.4. During the current assessment period, uMngeni uThukela Water utilised a total of 11.3 million kg of water treatment chemicals. There is an increase observed in the chemical usage as compared to the previous year. The reasons for the increase in the chemical use amount could be due to the treatment of high volumes of raw water with unsatisfactory quality associated with heavy rains, catchment activities and the operation of additional
plants. Furthermore, the increase in operational footprint. Water treatment chemicals were used to ensure that the quality of potable water was of acceptable standard and that the quality was maintained to the point of use.
uMngeni uThukela Water has implemented various initiatives to optimise the use of water treatment chemicals. These include:
uMngeni-uThukela Water’s objective of greening its operational and future infrastructure is driven and supported by its desire to move its business activities towards sustainable development. Green buildings not only reduce or eliminate negative impacts on the environment, by using less water, energy or natural resources, but may also have a positive impact on the environment by generating their own energy or by increasing biodiversity. Key drivers of the need for green building include climate change, energy, water security, waste reduction, healthy working environments and biodiversity, amongst others.
uMngeni-uThukela Water’s journey began with a Feasibility Study that focussed on assessing operational sites in line with the Green Building Council of South Africa Existing Building Performance Tool. The assessments presented green building strategies/recommendations, organized into the Water, Energy and Waste categories that uMngeni-uThukela Water can take forward to expand green building practices. As a water utility, uMngeni-uThukela Water can play a significant role in the green building sector through its comprehensive Capital Expenditure Programme which involves the provision of vital infrastructure required to enhance assurance of water supply. uMngeni-uThukela Water is currently developing policies and plans that will facilitate the adoption of green building principles and construction techniques into all types of future eligible developments.
uMngeni-uThukela Water’s objective of greening its operational and future infrastructure is driven and supported by its desire to shift towards environmental sustainability. Green buildings not only reduce or eliminate negative impacts on the environment by using less water, energy or natural resources, but may also have a positive impact on the environment by generating their own energy or by increasing biodiversity. Key drivers of the need for green building include climate change, energy, water security, waste reduction, healthy working environments and biodiversity.
As a water utility, uMngeni-uThukela Water can play a significant role in the green building sector through its comprehensive Capital Expenditure Programme, which involves the provision of vital infrastructure required to enhance assurance of water supply. Therefore, uMngeni-uThukela Water has since developed a Green Building Policy with the following objectives:
This policy will provide a framework to structure the approach to achieving sustainable design outcomes, commitment and minimum requirements for its implementation.
One of the projects that have been identified for Green Star Certification is the Lower uMkomaas Bulk Water Supply Scheme which is a scheme that will serve eThekwini Metropolitan Municipality and Ugu District Municipality. The planned infrastructure comprises the raw water infrastructure and the bulk water treatment works. The administration building situated at the water treatment works is earmarked for certification.
In 2019 uMngeni-uThukela Water Executive Committee and Board identified the deterioration in the quality of catchment water resources and the associate impacts of climate change as a
key strategic risk. This deterioration impacts on the quality and quantity of raw water resources which are paramount to uMngeni-uThukela Water’s core business of sustainable water supply.
Implications include supply limitation, high water treatment costs, high infrastructure design costs, decreased affordability by customers, non-payment for water services by customers and several other risks. The source of the problem of poor catchment health stems from several factors including, poor land use management practices, poor mindset and behaviour of water users towards water resources, lack of pollution reduction/prevention from source, lack of coordination of water resource management at catchment level, lack of compliance and enforcement by authorities, lack of institutional capacity within the governmental departments that are mandated for environmental and water resource protection and lack of integration between water users/stakeholders.
These issues are a symptom of a failure of traditional water resource management approaches in which water resource management was highly centralised and did not encourage a holistic approach to water resource management where there is:
In response to the serious and urgent challenge of deterioration of catchment health, uMngeni-uThukela Water established a Catchment Management unit within its scientific Services Division in 2019. The primary mandate of the unit/department is to work with other stakeholders (internal and external) mitigate catchment health and climate change risk through adopting a holistic and integrated approach to catchment or water resource management. This will be ensured through:
The catchment management initiatives undertaken by uMngeni-uThukela Water during the 2021/2022 period.
Catchment Assessments and landuse assessments are an essential tool in assisting uMngeni-uThukela Water catchment managers target their resources and select and implement the right measures in the right places. catchment assessments assist in providing answers to the following questions:
The following catchment assessments were undertaken during the period under review:
Overall outcomes of the catchment assessments indicated that the main land use and water uses types that affects catchment health within uMngeni-uThukela Water area of operation include discharges from waterwater treatment works, discharges from poorly maintained sewer infrastructure (sewer leaks, blocked and surcharging manholes), nutrient inputs from intensive agricultural runoff, poor solid waste management, terrestrial and aquatic alien invasive plant infestation, poor mindset and behaviour of water users towards water resources, ecological infrastructure transformation to agricultural lands, land degradation, poor development and spatial planning, chemical spillages from industries, location of sewer infrastructure i.e. pump stations in relation to water resources, illegal sand mining, soil erosion associated with catchment runoff, urbanisation and the associated poor sanitation services, unsustainable livestock farming, crop production and land degradation.
Well-managed and sustainable water resources are critical to uMngeni-uThukela Water’s core function of providing sustainable potable water supply. Alien aquatic weeds invading various water resources pose a significant risk to water quality and quantity. The aquatic weeds of main concern in uMngeni-uThukela Water impoundments and rivers include Water Hyacinth (Pntederia crassipes); Water lettuce (Pistia stratiotes); Kariba weed (Salvinia molesta); Parrots feather (Myriophyllum aquaticum) and Honwort (Ceratophyllum demersum). These free-floating and submerged aquatic plants are extremely difficult to control in eutrophic waters due to their exponential growth rate and invasion in the riverine environments. To ensure the effective management of these invasive weeds, interventions are implemented both in the upstream catchments as well as at the infested uMngeni-uThukela Water operated dams. In the upstream catchments, involvement of Non-Governmetal Organisations, Community Based Organisation, Non-Profit Orgnaisations organisations and Working for Water are critical in implementing control work. At uMngeni-uThukela Water operated dams, the main method of management is biocontrol (herbicide spraying and manual removal are considered as and when required in the critical parts of the dams where there is zero tolerance for any infestation due to strategic water abstractions that must not be interupted. For ease of management, dams are categorized into management zones which then allows implementation of suitable management methods in each of the zones i.e. Inanda Dam is categorised into three management zones namely:
The alien aquatic weeds management interventions undertaken in the year included:
Similar to aquatic alien weeds, terrestrial alien weeds infestation in riparian zones have significant impacts on sustainable water supply. The national environmental legislation on biodiversity management requires state-owned entities to put in place measures to control, monitor and eradicate terrestrial alien weeds. UMngeni-uThukela Water in partnership with Msinsi developed and implemented a plan to remove terrestrial alien weeds at uMngeni-uThukela Water operational sites specified in Table 11.3
Ecological infrastructure can be defined as the nature-based equivalent of built or hard infrastructure. It refers to ecosystems that function naturally to deliver invaluable services to people and the environment including enhanced water quality and improved quantity, soil erosion management, climate regulation and disaster risk reduction. Ecological infrastructure includes catchments, rivers, wetlands, groundwater resources, inland and coastal areas, nodes and corridors of natural habitats, which together form a network of interconnected natural structural elements in the landscape.
Unfortunately, assessments indicate that the majority of important ecological infrastructure upstream of uMngeni-uThukela Waters strategic dams is seriously modified as a result poor land management practices and lack of awareness on the importance of ecological infrastructure in water supply and disaster reduction. As a result, these green infrastructures are not able to provide the expected ecosystem services in their current degraded. Furthermore, South Africa is a water stressed country that is also facing the impacts of cycles of severe droughts and extreme flood events that are projected to increase in frequency, intensity and magnitude with the impacts climate change, especially in the eastern coastal areas where uMngeni-uThukela Water area of operation is located. Investment in ecological infrastructure rehabilitation and restoration, therefore, plays a significant role in providing services that supplements and at times substitutes built infrastructure solutions underpin socio-economic development. Well managed ecological infrastructure can increase the resilience of water resources to the human impacts as well as the impacts of climate change since green infrastructures such as wetlands and grasslands has the ability to enhance water quality, improve water quantity, buffer human settlements and built infrastructure against extreme events of floods and droughts, playing a cost effective role in disaster risk reduction.
Management and protection of ecological infrastructure ensures sustainable water availability, and therefore is as fundamental to uMngeni-uThukela Water’s business as grey or engineered infrastructure development. As part of its commitment to integrated catchment management, uMngeni-uThukela Water, therefore, considers investment in ecological infrastructure management as one of the key drivers for achieving the objectives of integrated water resource management which are to ensure coordinated management of water resources in order to achieve water resources protection, efficient use, conservation, control and sustainable management. UMngeni-uThukela Water’s initiatives on investment in ecological infrastructure are aligned to national government priorities and the National Development Plan objectives. This also include the key principles that guide investment in ecological infrastructure as recommended by the South African National Biodiversity Institute (SANBI). The ecological infrastructure related initiatives undertaken by uMngeni-uThukela Water in the year include:
uMngeni-uThukela Water updated the desktop wetland assessment undertaken in 2019/20 that included the identification of strategic l wetlands within uMngeni-uThukela Water area of operation. The study also involved the assessment of the present ecological status of the identified wetlands and prioritisation for implementation of interventions. The assessment revealed that the majority of wetlands within uMngeni-uThukela Water strategic catchments fall under the category C, D, E and F in terms of the present ecological status and this implies that these wetlands are characterised by high level of degradation that is associated with loss of natural habitat, biota and basic ecosystem function. The wetlands that were found to be highly degraded are located in the following quaternary catchments: Mooi River (V20A-D), Midmar (U20B and C), Msunduzi River (U20J and U20H), Karkloof (U20D) Ixopo (U10K), Nungwane (U70D), and uMdloti (U30A).
The prioritised wetlands for detailed assessment and restoration incudes the Darvill Waste Water Works Constructed Wetlands, Mpophomeni Waster Water Works Wetland, Sobantu Wetland at Baynespruit, the Ixopo Home Farm Dam wetland assessment and a feasibility study for a constructed wetland at the Mzimayi inflow to the EJ Smith Dam. The rational for this prioritisation has been the location of these wetlands in relation to the bulk water supply strategic water resources (Inanda Dam, Midmar Dam, Ixopo Home Farm Dam and EJ Smith Dam) that are compromised by upstream landuse practices and need to be supplemented by ecological infrastructure interventions that ensure sustainable supply of water that is fit for purpose.
In parallel to the broader wetland status assessment, uMngeni-uThukela Water, in collaboration with the Durban University Technology, is undertaking a research project to determine the potential of constructed floating wetlands to improve water quality in nutrient-rich environments. In this project, floating wetlands are piloted using a variety of plant species in several aquatic environments. Project implementation commenced in March 2021 and modest technology was used to identify the most appropriate non-invasive plant species that can improve water quality in nutrient enriched aquatic environments. the first results for the project are expected in the second quarter of the 2021/2022 year. If the project is successful, the floating wetlands approach will be implemented in other strategic areas where interventions are required.
In addition to the rehabilitation work and the development of rehabilitation strategies, uMngeni-uThukela Water, in collaboration with the Durban University Technology, is undertaking a research project to determine the potential of constructed floating wetlands to improve water quality in nutrient-rich environments. In this project, floating wetlands are piloted using a variety of plant species in several aquatic environments. Project implementation commenced in March 2021 and modest technology was used to identify the most appropriate non-invasive plant species that can improve water quality in nutrient enriched aquatic environments. If the project is successful, the floating wetlands approach will be implemented in other strategic areas where interventions are required.
The Department of Water and Sanitation in collaboration with uMngeni-uThukela Water and the Trans-Caledon Tunnel Authority plans to implement the Mkomazi-Mgeni Tranfer Scheme to augment water supply in the Mgeni System so water demands from eThekwini metro and surrounding areas can be met. The major challenge is that the catchment upstream of the proposed Smithfield Dam in the Mkomazi River is unlike any other in the greater uMngeni River Basin. Much of it is already highly degraded, especially in areas under communal tenure and a significant proportion of the remainder is at very high risk of future similar degradation. Technical experts have generated a number of scenarios related to the rate of sediment deposition that might occur in the proposed dam and the most reasonable scenario indicate that the dam would lose about half of its volume to sediment over 100 years.
In addition, highly turbid due to sedimentation and siltation will contribute significantly to an increase in purification costs. Climate change, bringing both droughts and more intense rainfall events to this area, is likely to accelerate erosion and subsequent dam sedimentation and further increase turbidity. Population demographics for the Mkomazi area show that 68% of people living in the area have no formal income and 10% earn less than R3500 per month. Women are particularly vulnerable with 8755 female-headed households of which about 3492 are reliant on unprotected water sources. Many households survive by supplementing social grant and transfer payments with small-scale stock and crop production. UMngeni-uThukela Water has therefore took an initiative to collaborate with stakeholders to engage in an upper-catchment scale intervention that conserves and/or restores this landscape. In addition to improving water security and reducing the cost of water provision this initiative creates significant direct and indirect economic opportunities to local residents and improve biodiversity with associated ecosystem benefits. This proposed intervention is of considerable magnitude and is costly. However, it is anticipated that the benefits of successful conservation and restoration will, over the long term, far outweigh the costs. The dam itself (estimated cost at R30 billion) is likely to deliver limited local economic opportunities and most benefits benefits will accrue from upstream protection rather than from the dam itself. First phase of the project was completed in 2020 and phase 2 commenced in the latter part of 2020 and will be finished towards the end of 2023, then phase 3 will follo. Phase 2 is a continuation from from phase 1 and focuses on the implementation of the plan that was developed during phase 1.
The overall objective of this project is use nature based solutions to address the severe land degradation and invasive alien plant infestation in the Upper Mkhomazi Catchment so as to improve water security, the livelihood prospects of local residents and biodiversity outcomes. This is being achieved through implementation of catchment management and ecological infrastructure interventions at degraded areas located upstream of the proposed Smith Field Dam.
The Ecological Infrastructure for water security project is a five year $7.2 million (approximately R90 million) worth investment from the Global Environment Facility (GEF) with considerable co-finance from various collaboration South African partners. The Department of Environmental Affairs is the National focal point for this project, the Development bank of South Africa (DBSA) is the Implementing Agent for the GEF and SANBI is the project executing agency. The Project aims to transform the way people think about, value and invest in water and ecosystems, and will lead to increased investment in the management of ecological infrastructure in the future.
The project acknowledges the reality that, South Africa’s water security depends not only on our built water infrastructure, but also on well managed land in our catchments. Healthy wetlands, grasslands, rivers and groundwater ecosystems in the landscape will make our future more water secure. These are ecological infrastructure that can generate and deliver significant improvements in water quantity and quality if we look after them. Investing in ecological infrastructure in conjunction with built infrastructure, will deliver more clean water from our land. Investments are particularly important in strategic water source areas where ecological infrastructure assets are under-protected and slowly, or sometimes rapidly degrading.
There is an urgent need to bring investment in the management, maintenance and restoration of ecosystems into the planning, financing and development in the water sector. Such investments will create more jobs and advance our nation’s developmental agenda, especially in face of a changing climate. Designed in close consultation with the Department of Water and Sanitation (DWS), the project supports the implementation of the National Water Resource Strategy and it is included as part of the Call to Action in the Water and Sanitation Master Plan. Project implementation is through a suite of partnerships involving several other public, private and civil society organisations, such as the DWS, the Water Research Commission, WWF-SA and recently uMngeni-uThukela Water.
The project was launched at the DBSA as a development finance institution with the ability to take the country’s natural capital into account in development financing. This project themed “Nature for Water” foregrounds nature based solutions to the water challenges we face in the 21st century and places South Africa at the forefront of this work globally and has taken important steps towards demonstrating the return on investment in ecological infrastructure in terms of actual water-related benefits in South Africa over the long term. Finally, the EI4WS project is about ensuring living landscapes that deliver more water to communities and cities. Unlocking this potential will contribute towards South Africa’s National Development Plan, our National Infrastructure Plan, it will support the implementation of the National Water Resource Strategy and contribute to meeting the Sustainable Development Goals.
During 2021/2022, uMngeni-uThukela Water signed a collaboration agreement with SANBI to lead and implement component 2.2 of the project under the theme “Enhanced organizational capacity and investment in ecological infrastructure in the Greater uMngeni catchment to improve water resource management” on outcome 2.2.2 that is looking at determining the full costs of rehabilitation and maintenance of water related ecological infrastructure and determining the associated Compliance Monitoring and Enforcement (CME) in order to support the mainstreaming of ecological infrastructure into the financing of water resource management and development.
uMngeni-uThukela Water scope of work includes the following:
UMngeni-uThukela Water has made considerable investments in this project through
The National Water Act, Act No 36 of 1998 (NWA), requires that water-use licences are obtained before any water-use activity or development can be undertaken. Water use is defined as undertaking activities that have an impact on a water resource. The impact may be on the amount of water in the resource, the quality of water in the resource and the environment surrounding the resource. Section 21 of the NWA lists 11 water uses as requiring a water-use licence before they can be undertaken. Of the 11 listed water uses, only seven are applicable to uMngeni-uThukela Water and include:
Water users can include any entity or individual whose operations trigger the water uses that are listed in section 21 of the NWA. To ensure compliance with the requirements of the NWA, the water-use licence status and compliance was monitored and quarterly reporting was undertaken. This included developing and implementing action plans to obtain outstanding licences and compliance with the conditions of the existing authorisations.
The status of water use licence applications for CAPEX Projects (new infrastructure development projects) is presented in the figure below:
Catchment parameter monitoring is a fundamental component of water supply services. uMngeni-uThukela Water catchment parameter of interest include water quality, hydrology (rainfall, river level, streamflow and evaporation), land use change, soil erosion (sediments), river health, wetland health and climate data. However, existing catchment monitoring is sparce, difficult to obtain and variable in content and accuracy. Remote Sensing (satellite imagery and drone technology) and Citizen Science technology and innovation presents an opportunity for closing the existing data and information gaps, since these innovations can provide data over a wide area. These innovations present a huge potential for improved spatial coverage yet they are currently largely restricted to the research domain. uMngeni-uThukela Water in collaboration with stakeholders undertakes a numbers of remote sensing and citizen science projects and initiatives.
The remote sensing projects that were undertaken during the period under review include the following: operationalising water Quality Monitoring Using Satellite Imagery – A feasibility Study
This study was undertaken in collaboration with Geoterra Image as and used Sentinel-2 satellite image and uMngeni-uThukela Water in-sutu water quality data using Inanda Dam and Nagle Dam as pilot studies. The study focused on the following water quality parameters:
The primary objectives of the study were to:
The results of the study confirmed the feasibility of using 20m Sentinel-2 to generate qualitative and quantitative representations of chlorophyll-a and Turbity levels in dams with acceptable modelling and calibration accuracies, using published water quality algorithms. The study highlighted that a final analytical step is still required to determine appropriate concentration threshold values necessary to reliably separate the modelled chlorophyll-a and turbidity levels and ensure correct spatial representations of each characteristic.
For algal concentration, the study indicated that further work is required to demonstrate the feasibility of using sentinel-2 image to detect levels of algal concentration. The results indicated that use of published algal count algorithms on Sentinel-2 imagery does not generate the suitable levels of quantitative accuracy to support quantitative operational use. As such, the study recommended repeating the algal analyses component of the study using Sentinel-3 image data as the next necessary step.
This project was undertaken in collaboration with the Institute of Natural Resources and the Cape Penisula University of Technology. The primary aim is to investigate the feasibility of using drone technology to undertake catchment parameter monitoring. The scope of work includes undertaking a literature review and undertaking a trial flight over the selected pilot sites. The catchment parameter of interest for this project includes the following:
The literature review was completed in June 2021, while the trial flight was undertaken in July 2021. The results of the study indicates that:
The Amanzi Ethu Nobuntu initiative is a multi-stakeholder citizen science project that is a presidential employment stimulus initiative led by the Department of Science and Innovation and implemented by DUCT. For phase 1 of this initiative uMngeni-uThukela Water provided co-funding for 20 envirochamps that were working at two Baynesspruit sites. The project provided employment to more than 300 young people for three months. The citizen science tools that were utilised in the project included the following:
As part of this project uMngeni-uThukela Water provided co-funding to update the State of the Rivers Report (SOR) for the Mooi-Mngeni Catchment. The SOR is an important catchment management reference and was last updated in 2002. This initiative afforded an opportunity for the uMngeni-uThukela Water catchment management graduate trainees to be seconded to the project and received capacity buisling on undertaking the situational and gap analysis, water quality sampling and Water Quality Index. The final State of Rivers Report will be available in 2022.
For phase 2 of AEN which took place during 2021/2022, uMngeni-uThukela Water in Collaboration with institute of Natural Resources (INR) supported 70 Enviro Champs and placed them under the Upper Mkhomazi initiative.
Msinsi Holdings Sustainable Land and Resource Management
Msinsi Holdings SOC Ltd, a wholly-owned subsidiary of uMngeni-uThukela Water, is mandated to manage the land and biodiversity of the areas around the dams owned or managed by uMngeni-uThukela Water in a manner that balances the divergent factors of local community development provision of recreational facilities for the public and water resources/biodiversity protection.
These reserves are located at:
The following sites have been incorporated into the scope of Msinsi for implementing catchment management interventions associated with alien invasive plant eradication:
Detailed management plans for each of the reserves in line with industry best practice have been completed and form the basis for all operations in the reserves. In the past year, Msinsi succeeded in protecting the habitats and ensuring an ecological sustainable and protected water environment through implementing its resource management plans which focused on:
The management of the game and species according to the carrying capacity of each reserve;
The ecological balance was managed effectively during this period through the implementation of Reserve Management Plans. In particular, carrying capacity was managed to ensure sustainability of wildlife populations and measures to mitigate poaching, which has been a significant threat to the reserve wildlife, were put in place. Security patrols are conducted as per a patrol plan to identify
and mitigate security risks to the reserves including ensuring reserve fence lines are in good condition.
Msinsi Holdings continues to be seen as a significant player in the conservation and tourism sector in KwaZulu-Natal. The state-owned company will continue to ensure that ecosystem services provided by water and environmental resources continue to be sustainable. Stakeholder engagement successfully created value for Msinsi’s operations and the communities at large during this reporting period. As a result, there was no interruption of Msinsi’s operations as a result of community instability in the neighbouring areas. Msinsi continued providing environmental education targeting surrounding communities. A total of 82 environmental education initiatives in areas of water conservation environmental awareness and commemoration of environmental special days were implemented.
Sourcing labour within the communities around Msinsi operations created job opportunities for the communities, with a total of 1058 temporary jobs created during the reporting period.
In partnership with other stakeholders, six graduates, in-service trainees and interns received training opportunities in fields ranging from Hospitality to Human Resources Management. Msinsi Holdings is planning to sustain its training programmes to continue to contribute to skills development, particularly for the youth from neighbouring communities.
uMngeni-uThukela Water has solidified its commitment to conserve scarce natural resources and reduce the environmental impacts of its operational activities through environmental sustainability initiatives. The initiatives aim to transform the organisation from the typical wasteful linear economic model (of take-make-use-dispose) to an economic model that enables economic growth, while aiming to optimise the operation chain in a more sustainable approach. Waste minimisation was identified as one of the crucial initiatives in reducing the amount of waste that is disposed at landfill sites. A notable increase in the hazardous waste was observed during the reporting period, this increase might be due to the Covid Regulations, that resulted in an increased volume of the hazardous waste. The total amount of waste that was produced is 1115 kg per million m3 and 13.25% of the waste was recycled (Figure 11.7 and 11.8)
The management of Water Treatment Residues (WTRs) and wastewater sludge forms an integral component of the core business of uMngeni-uThukela Water. Current sludge management practices include on and off-site disposal and river discharges. However, these practices are not sustainable because of the environmental impacts associated with on-site disposal, the limited landfill space and the impact of the river discharges on the aquatic ecosystem. Moreover, the current sludge management practices have posed challenges in recent years from changes in the environmental legislation, with additional requirements for expensive landfill liners and leachate management at all landfill sites. This triggered the need for uMngeni-uThukela Water to develop a comprehensive Sludge Management Plan (SMP) for its operational sites.
The WTRs will be applied to agricultural land as a soil conditioner whilst the wastewater sludge will be used as organic compost. Wastewater sludge contains organic matter and nutrients that can provide soil benefits. Planned work is to design and pilot a long-term solution that will transform both management of WTRs and wastewater sludge from a liability into an asset on a commercially representative scale.
Annual environmental audits are undertaken at operational sites the objectives, which are:
Operational environmental audits were conducted at 24 sites for 2021/2022. Out of 48 findings, 6 findings were rated major.
Mitigation measures and action plans have been instituted to address these findings
In the year under review, there were 18 environmental incidents recorded for the 2021/2022 financial year (69 incidents in 2021). This indicates a decrease in the number of incidents from the previous year. Figure 11.9 provides the comparative analysis for the past five years.
uMngeni-uThukela Water’s core business function is to provide water services – water supply and sanitation services – to other water services institutions. Business relies highly on the natural resource, which is freshwater resources, although there has been measures to venture into other sources of water. In this regard, the natural
uMngeni-uThukela Water, a state-owned entity, is one of Africa’s most successful organisations involved in water management and is the largest supplier of bulk potable water in the Province of KwaZulu-Natal, South Africa.
The organisation was established in 1974.
