Initially seen as the separate Sabie catchment draining the Sabie River, and the Sand catchment draining the Sand River, these drainage basins are collectively classified by The Department of Water Affairs and Sanitation (DWS) as the X3 secondary drainage region. This catchment lies to the north of the greater Inkomati-Usuthu Water Management Area (IUWMA). The primary Sabie River flows from its headwaters originating east of the Great Escarpment through various towns, such as Sabie, Hazyview and Skukuza, which is situated in the Kruger National Park (KNP) to its cross- boundary end in the Corumana Dam, Mozambique. Two of its tributaries were considered important within this study (Sand and Marite rivers) as well as the Inyaka Dam (also called Injaka Dam) situated within the Marite River. Forestry, commercial plantations, cultivated commercial lands and urban land uses were suspected of having increasing water demand on the water resources of the catchment. The densely populated, rural or semi-urban developments within the catchment have raised increasing concerns over the past two decades due to the substantial increase in population. Initially it was pressures from the increasing water supply (lifted by the Integrated Water Supply Scheme from the Inyaka Dam) that impaired the livelihoods of the still expanding Bushbuckridge community. Now, water quality has raised increasing concerns with regards to both Bushbuckridge and the urban township Thulamahashe. As responsibility towards the conservation practices of the KNP; the international water agreement between South Africa, Swaziland and Mozambique; and the protection of catchment water resources, this study was initiated with regards to the influence of land use on water quality. It is very important to note that certain parts of South Africa had suffered a climatological drought from 2013 to 2016, so this study assessed the river water quality experienced within a dryer rainfall period and should be interpreted as such. This relates to an international issue of concern, namely dwindling potable water supply. Intense human activities conducted by using earth’s surfaces, influence water quality. It has become highly important to assess water issues with regards to land use as indicator of human activities. The main aims of this study were to do an in-depth determination of the different land uses surrounding the Sabie-Sand River Catchment; and to evaluate the influence thereof on the water quality of the Sabie River and its two major tributaries including the Inyaka Dam. It also focused much attention on the possible effects that urbanization had on water resource quality. Therefore, it was necessary to conduct in situ field investigations and GIS spatial analysis towards answering the research problem. Every three months, surface water samples were collected form 12 sites in the Sabie-Sand catchment. This was done over a period of a year, as to include results from all four climate seasons. Major chemical, biological and physical water quality parameters were measured; ii analysed with accredited methods from the South African National Accreditation System (SANAS) by Rand Water Analytical Services laboratory, and interpreted by use of Spearman Rank correlation and Kruskal-Wallis ANOVA statistical methods. Spatial analysis conducted through ArcGIS version 10.4 (Esri, 2015), made use of the 3D analyst, spatial analyst and network analyst extensions in ArcGIS for land use interpretation. The main spatial datasets used for interpretation were the 2013/2014, 72 Class South African National Land Cover Dataset (GeoTerraimage, 2015) and the SRTM90 Digital Elevation Model (DEM) (Jarvis et al., 2008). Assessing spatial influences on water quality, a multivariate redundancy analysis (RDA) was conducted to compare both datasets. The results indicated that there was no significant relationship between land use and water quality for the Sabie-Sand catchment, but it was identified that land use still played a major role in the water quality of the catchment. Since the state of the rivers report conducted by Roux and Selepe (2011), the land uses in terms of forestry and the upper part of the Sabie River have not changed as much as the urban expansion of peri- urban areas, urban villages and urban townships have. The reason for saying this is that forestry, commercial plantations and cultivated commercial lands showed lesser adverse influence on water quality and that the major negative influences were urban in nature. The urban township Thulamahashe had the most negative impact on the water quality of the Sand River, tributary of the Sabie River. This was related back to effluent from the wastewater treatment plant on the Sand River. Discussed in Chapter 4 of this study are the water quality parameters that identify organic pollution from anthropogenic activities. These parameters were either high or in exceedance of drinking water standards. This is seen in exceedingly high Escherichia coli (E. coli) and Total Coliforms (coli) concentrations that were associated with high Chlorophyll-a (Chl-a), Chemical Oxygen Demand (COD), dissolved inorganic nitrogen (DIN), Dissolved Organic Carbon (DOC) and geosmin. With low concentrations of DO for this site, accompanied with the high coli, DOC, Total Organic Carbon (TOC) and COD this might indicate rapid bacterial growth. Support should be provided to this urban settlement in the form of adequate water supply and sanitation facilities, primarily starting with the known point pollution wastewater treatment plant. Adequate maintenance and monitoring should be insisted on at the plant to ensure effluent that conform to national water quality guidelines.

BOX 75, PILGRIM'S REST, 1290 1 EXECUTIVE SUMMARY A Phase 1 Heritage Impact Assessment (HIA) regarding archaeological and other cultural heritage resources was conducted on the footprint for the proposed Sabie Hydro Power project next to the Sabie River near Hazyview. The study area is located on portion 17 of the farm TEVREDE 178JT, Hazyview. The farm is situated on topographical maps, 1:50 000, 2530 BB (SABIE) & 2531 AA (KIEPERSOL), which is in the Mpumalanga Province. The study area is situated on 2530 BB SABIE. This area falls under the jurisdiction of the Ehlanzeni District Municipality, and Thaba Chweu Local Municipality. The National Heritage Resources Act, no 25 (1999)(NHRA), protects all heritage resources, which are classified as national estate. The NHRA stipulates that any person who intends to undertake a development, is subjected to the provisions of the Act. The applicants (private landowner with some shareholders) in co-operation with Rhengu Environmental Services are requesting the establishment of a hydro facility on the Sabie River near Hazyview. There was a hydro facility on the farm approximately 40 years ago and the new one will follow more or less the same route and alignment.

Abstract - The present study investigated the hydrochemical Various anthropogenic sources which include mining, characteristic changes of the Sabie River catchment. Water sampling agricultural activities and industrial wastewater contribute to was done in November and December (wet season, 2019) and July pollution of surface water [1], [2]. Various factors that influence (Dry season, 2020). Physicochemical parameters and metal speciation were analyzed to assess their impact on water quality and fitness for the mobility of the likely or definite contaminants from human consumption. The hydrochemical characteristics of Sabie anthropogenic activities such as mining and mineral processing catchment showed variation of quality with seasons when compared activities had been described [3] and [4]. These factors include with drinking water guidelines. Seepage from Nestor tailings storage occurrence, abundance, reactivity and hydrology. The term facility (TSF) was also collected during wet season. In both season, species had been defined as different forms of a particular aqueous metal speciation was done using the PHREEQC geochemical 2+ 2- element or its compounds [5]. For this study, the term speciation modelling code. Higher concentrations of Ca and SO4 were found in mine water while the dominant anion and cation were Mg2+ and Cl- had been used to indicate the distribution of species in samples in surface water samples. Additionally, the seasonal variation in the from the Sabie catchment.

  • River Flow and Quality
    Setting the Thresholds of Potential Concern for River Flow and Quality Rationale All of the seven major rivers which flow in an easterly direction through the Kruger National Park (KNP) originate in the higher lying areas west of the KNP where they are highly utilised (Du Toit, Rogers and Biggs 2003). The KNP lies in a relatively arid (490 mm KNP average rainfall) area and thus the rivers are a crucially important component for the conservation of biodiversity in the KNP (Du Toit, Rogers and Biggs 2003). Population growth in the eastern Lowveld of South Africa during the past three decades has brought with it numerous environmental challenges. These include, but are not limited to, extensive planting of exotic plantations, overgrazing, erosion, over-utilisation and pollution of rivers, as well as clearing of indigenous forests from large areas in the upper catchments outside the borders of the KNP. The degradation of each river varies in character, intensity and causes with a substantial impact on downstream users. The successful management of these rivers poses one of the most serious challenges to the KNP. However, over the past 10 years South Africa has revolutionised its water legislation (National Water Act, Act number 36 of 1998). This Act substantially elevated the status of the environmental needs, through defining the ecological reserve as a priority water requirement. In other words this entails water of sufficient flow and quality to maintain the integrity of the ecological system, including the water therein, for human use. With the current levels of abstraction in the upper catchments, the KNP quite simply does not receive the water quantity and quality required to maintain the in-stream biota.
