Fourie Heritage Specialists/ Principal Investigator Reviewed B Khupe EIMS HIA – Project 3: Giyani WWTW iii EXECUTIVE SUMMARY PGS Heritage (PGS) was appointed by EnvironMental IMpact ManageMent Services (Pty) Ltd (EIMS) to undertake a Heritage IMpact AssessMent (HIA) that forMs part of the Basic Environmental IMpact Report (BAR) for the proposed upgrade of the Giyani Waste Water TreatMent Works (WWTW), Giyani, LiMpopo Province. The following section provides a suMMary of the project locality, scope, heritage resources, envisaged impacts and recoMMendations. 1 SITE NAME Giyani Waste Water TreatMent Works (WWTW), Giyani, LiMpopo Province. 2 LOCATION The Giyani WWTW (coordinates - E30.70835, S23.32537) is situated on the western outskirts of Giyani, just east of the Klein-Letaba river in the Greater Giyani Municipality of the LiMpopo Province (Figure 3). Figure 1 – Study area locality HIA – Project 3: Giyani WWTW iv 3 DESCRIPTION OF PROPOSED DEVELOPMENT The project involves the refurbishMent and upgrade of the existing Giyani Wastewater TreatMent Works (WWTW). The WWTW is currently operating at a hydraulic loading of approxiMately 6 Ml/day (6000M3/day). It is proposed that the existing works will be deMolished to create space for the proposed upgraded works of 14Ml (14000M3/day). The new works will consist of two equal activated sludge reactors, each of 7Ml capacity. The upgrade will also incorporate a new inlet works able to handle the projected inflow at the end of the 20 year planning period. After coMpletion, the teMporary activated sludge works shall be demolished, but the current biological filter plant shall be retained as a backup facility. The existing facultative ponds shall be converted to eMergency overflow daMs in order to deal Mainly with storm water ingress during rainy periods. The existing chlorination systeM will also be refurbished and upgraded. The developMent footprint will be up to 2 ha in size 4 HERITAGE RESOURCES IDENTIFIED None 5 ANTICIPATED IMPACTS ON HERITAGE RESOURCES None 6 RECOMMENDATIONS The field work coMponent of the study confirMed that no heritage resources occur within the development area and thus no iMpact is foreseen on heritage resources. This developMent will not negatively affect palaeontological heritage. If in the extreMely unlikely event, that fossils are exposed in younger alluvial deposits in the process of developMent activities, a qualified palaeontologist Must be contacted to assess the exposure for fossils so that the necessary rescue operations are iMpleMented. HIA – Project 3: Giyani WWTW v No iMpact on heritage resources is likely. However in the event of any heritage resources are uncovered SAHRA should be contacted and a qualified archaeologist appointed to evaluate the finds and Make appropriate recoMMendation on Mitigation. The overall iMpact of the developMent on heritage resources is seen as low and there is no reason why the upgrades to the Giyani WWTW cannot be approved. 7 AUTHOR/S AND DATE Wouter Fourie Date: 21 January 2016 Accredited Professional Archaeologist (ASAPA) Accredited Professional Heritage Practitioner (APHP) Jessica Angel (Archival research) Marko Hutten (Field assessment) Accredited Professional Archaeologist (ASAPA) Accredited Professional Archaeologist (ASAPA) HIA – Project 3: Giyani WWTW vi The heritage iMpact assessMent report has been coMpiled taking into account the NEMA EnvironMental IMpact AssessMent regulations (GNR 982) appendix 6 requirements for specialist reports as indicated in the table below.
