    Infrastructure delivery management challenges in KwaZulu-Natal : a review of the operations and maintenance module
    (Seybold Publications, 2024-10-22) Hadebe, Weziwe; Armoed, Zakheeya; Mewomo, Modupe
    Globally, governments have prioritized infrastructural policy and infrastructure development as the key to economic development. Efforts to accelerate effective infrastructural delivery in South Africa gave rise to the development of a government-wide tool called the Infrastructural Delivery Management System (IDMS). This was developed as a standardized approach for the planning, budgeting, procurement, operations, maintenance, decision-making and general management of South Africa’s infrastructural development across all tiers of government. The study explores the effectiveness of implementing the Operations and Maintenance (O&M) module of the IDMS in the province of KwaZulu-Natal (KZN). Focusing on the KZN province, the study utilizes a mixed method research approach. Articles were sourced from databases which included Scopus, Web of Science, Google Scholar and Governmental platforms. Peer-reviewed studies in the English language that were published between 2010 to 2024 were identified. Key search terms were infrastructure delivery management system, challenges, operations, maintenance, and efficiency that informed the literature review of the study. The study drew a sample of 133 participants responsible for infrastructural delivery using purposive sampling. Data was analyzed using thematic and content analysis. Findings suggest within the ecosystem of infrastructural development in the KZN province, the necessary IDMS capacity and capabilities do exist. However, the impact of different institutional roles, responsibilities and concurrent functions; in coordinating and implementing the IDMS, has influenced a growing backlog in public infrastructural delivery in KZN. This can be attributed to the failures in coordination resulting in the efficiencies of the O&M module. Through the resurrection of district maintenance workshops and decisive leadership in response to poor operational and maintenance plans, the application of IDMS may prove to be successful in alleviating infrastructure backlogs across all tiers of governance.

    Exploring the challenges and opportunities of farm school infrastructure in Kwa-Zulu Natal, South Africa
    (RealCorp, 2022-11-16) Pillay, Nischolan
    South Africa is a country that has a rich history of segregation of races driven by a minority government. Through the ill system of apartheid, several aspects of human life became intolerable, one of which was the education system. The introduction of the Bantu Education Act of 1953 indoctrinated African learners by educating them to perform menial tasks and manual labour, becoming subservient to the white minority. This “knee on throat” system further oppressed Africans, making it difficult to progress and preserving the idea of education being a privilege and not a right. The act played out at various “black” schools in South Africa, especially farm schools, which created an economic benefit for the farmers. The farm school became a factory to create a new labour force, whose parents were smoke screened to believe paid education would benefit their children. In 1994, a new dawn for all the people of South Africa promised hope and freedom. The government promulgated laws that would benefit citizens’ human rights and allow those who needed them the most. The redress of education policies aimed at giving all South Africans a fair opportunity for education; however, this is seldom the case in most of the country’s impoverished rural and farm schools. The government, through legal frameworks, aims to convert schools on commercial farms to normal stateowned and managed institutions, removing the dependence on the farm owners. However, this process has been arduous, and the farmers’ kick has been great to the extent that children and teachers are restricted from entering the premises. Regular intervention by police and government officials assists; however, this is not long-term management of deep-seated problems. Although the government has taken many steps in the right direction, at the very core, farm schools still suffer from infrastructural issues that are so profoundly entrenched in the buildings that it is difficult to dismantle. Perhaps, like most of South Africa, the apartheid regime is built in brick and mortar. These farm schools, in most instances, do not comply with the basic regulations of the South African Schools Act of 1996. However, these schools continue to operate and educate students across the country. Using a phenomenological paradigm and a qualitative approach, this research uses semi-structured interviews conducted at two farm schools in Kwa-Zulu Natal, South Africa, to gather rich data from participants. This study is limited by cost and time. The researcher used a purposive sampling technique to identify four participants who were probed on different aspects of the farm school infrastructure and experiences working and using the facilities. This research aims to understand the challenges and opportunities that farm schools offer. Findings from the data reveal that although farm schools have several infrastructural challenges, the staff and community adapt the use of these buildings to suit the needs of the activities, albeit with challenges. The researcher proposes adaptive reuse of the infrastructure to suit a school’s programme and provide space for a community.

    An investigation of the condition of maintenance of facilities at public primary and high schools in Alfred Nzo East District, Eastern Cape Province South Africa : a literature review
    (2023-08-10) Nqakaza, Bavuyise G.; Chikafalimani, Samuel Herald Peter
    This paper reviews literature on the condition of maintenance of facilities at public primary and high schools (PPHS) at Alfred Nzo East District (ANED) in the Eastern Cape Province (ECP) in South Africa. Scoping review of accessible literature was the research approach used to collect data for the paper. Results of the study identified: overcrowding of facilities, poor design and planning of facilities, lack of facilities maintenance knowledge and skills of school governing bodies (SGBs), and lack of funding for facilities maintenance as main causes of the poor maintenance condition of facilities at PPHS in South Africa. It was revealed through the study also that poor maintenance of facilities at PPHS caused: poor learning and teaching environment; poor performance of learners and educators; scarcity of educators; and security, safety and health concerns at PPHS. Furthermore, the study identified: prioritization and provision of government funding for extension and construction of new school facilities, inclusion of well qualified facility managers and users at facility planning stage, and provision of facilities training to SGBs as main interventions that can be implemented to improve the condition of maintenance of facilities at PPHS in South Africa. Findings of this study will contribute towards the improvement of the condition of maintenance of facilities at PPHS, support high quality education delivery, reduce unemployment and poverty, and accelerate economic development at ANED and in other parts of South Africa in the future

    Water quality modelling and quantitative microbial risk assessment for uMsunduzi River in South Africa
    (IWA Publishing, 2022-04) Ngubane, Zesizwe; Bergion, Viktor; Dzwairo, Bloodless; Troell, Karin; Amoah, Isaac Dennis; Stenstrom, Thor Axel; Sokolova, Ekaterina
    South African rivers generally receive waste from inadequate wastewater infrastructure, mines, and farming activities, among others. The uMsunduzi River in KwaZulu-Natal, South Africa, is among these recipients with recorded poor to very poor water quality. To identify parts of the uMsunduzi River that are polluted by Cryptosporidium and Escherichia coli (E. coli), this study mapped out pollutants emanating from point and non-point sources using the Soil and Water Assessment Tool (SWAT). Streamflow calibration in the upper and lower reaches of the catchment showed good performance with R2 of 0.64 and 0.58, respectively. SWAT water quality output data were combined with a Quantitative Microbial Risk Assessment (QMRA) to understand the microbial health implications for people using river water for drinking, recreational swimming, and non-competitive canoeing. QMRA results for Cryptosporidium and pathogenic E. coli showed that the probability of infection for most users exceeds the acceptable level for drinking and recreation as outlined in the South African water quality guidelines, and by the World Health Organization (WHO). The results of this study can be used as a baseline to assess the economic and health implications of different management plans, resulting in better-informed, cost-effective, and impactful decision-making.
