<p>"Orange River System (ORS) is one of the most highly developed River Systems in Southern Africa. In September 2015, Namibia and South Africa, under the auspices of the PWC, commissioned the Noordoewer / Vioolsdrift Dam (NVD) Feasibility Study, which aimed at identifying and optimising the best development dam size(s), site(s) and sequence of dam developments in the ORS needed to achieve the overall catchment objectives, to re-regulate the flows for ecological needs and to increase the yield in the Orange River System for use by both RSA and Namibia. The study was completed in May 2020.
The study investigated many possible options and in 2016 initially concluded that the optimal NVD would have a wall height of about 73 m, with a storage capacity of 2,800 million m3 and would be of concrete faced rock fill type (CFRD).
Certain limited further feasibility studies are required before the project can proceed to implementation Such studies would include at least an independent review of the above independent review of the above findings, the finalisation of the exact parameters for the recommended optimal NVD in terms of size, site and type, and obtaining environmental authorisation for implementation.
The development of the NVD project will involve the following further stages:

<p>The purpose of the Noordoewer/Vioolsdrift Dam (NVD) would be to: i) increase the longterm sustainable yield of the Orange River System to replace the loss in yield due to the planned commissioning of the Lesotho Highlands Water Project Phase 2 (LHWP-2) and associated transfers to the Vaal River System; ii) provide for the projected growth in water requirements in the Orange River System, specifically future largescale irrigation developments in Namibia in the Lower Orange River System, both upstream and downstream of the proposed NVD site; iii) compensate for the impact of the implementation of the Reserve on the yield of the Orange River System; and iv) provide a re-regulation storage on the Lower Orange River to allow for releases to be made to correct the seasonal distribution of flows in accordance with the riverine Ecological Water Requirements (EWRs) in the Lower Orange River.</p>
