230807001841 - Supply Scenario 1 of the Desalination Plant and Water Carriage System to Secure Water Supply to the Central Coast, Namibia

The objective of the proposed Desalination Plant and Water Carriage System is to supply potable water, derived from seawater desalinated at the coast, through a pipeline system to various supply areas as indicated below: • Supply Scenario SS1: Supply additional potable water for the Central Coastal Area only (CCA); • Supply Scenario SS2: Supply additional potable water for the CCA, the area around Windhoek (CAN) and for en-route Users along the transmission pipeline; • Supply Scenario SS3: Supply additional potable water for the CCA, the area around Windhoek (CAN) and for users along the supply pipeline as well as an additional 20 Mm³/a to Gaborone from 2029. This scenario was not considered during the execution of the Environmental Scoping Study. Following the feasibility study NamWater has decided to proceed with the preferred water supply scenario referred to as Supply Scenario 1 (SS1), comprised of the proposed Desalination Plant and Water Carriage System to supply water to the CCA of Namibia only. The proposed Desalination Plant and Water Carriage System project for Supply Scenario 1 will consist of the following key components (as shown in Figures 1 and 2 attached): • The Desalination Plant and Pump Station 1 (Desalination Plant proposed area); • The Intake works and Intake Pump Station; • A pipeline linking the two places mentioned above; • An approximate 4 km pipeline connecting the desalination plant to the existing 1200 mm diameter pipeline; and • The #Gaingu PV Power Plant and power line connecting to the new Khan 33 kV substation. The application was made to MAWLR and MEFT for the Scoping Phase (APP- 00687). Due to the crash of the MEFT online system a new application needs to be made. The #Gaingu PV Power Pant facility will have a separate ECC application form, Environmental and Social Impact Assessment report and Environmental and Social Management Plan. 3.
