Project title
Vaal‐Gamagara Water Supply Project (Project XB‐2)
Project sponsors
Participating countries
Objectives
The project proponent is the Department of Water Affairs, Botswana.
Botswana and South Africa
To transfer water from the Vaal River so as to provide some 50 000 residents of south‐
western Botswana with an adequate and safe domestic water and sanitation service.
Project description
Water availability in Botswana decreases from the east to the west with the south‐
western corner of Botswana having the least reliable water supply. The residents in
this area suffer constant water supply constraints, which compromises their quality of
life. As most of the country’s water sources are found in the north‐east of the country,
Botswana has proposed that water supplies to the southwest be sourced from the
Vaal River in South Africa, which is part of the Orange‐Senqu River Basin. Botswana is
a member of the Orange‐Senqu River Basin Commission (ORASECOM) and therefore
has rights to the water of the basin in terms of the agreement that establishes
ORASECOM. Botswana’s proposal is to draw up to maximum of 5 million m3 of water
annually from the Vaal, and to deliver this to the villages in the extreme southwest of
the country through the Vaal‐Gamagara Water Transfer Scheme. The scheme will
involve the construction of cross‐border water transfer infrastructure over an
estimated distance of 400 km. It is assumed that there will be no dam constructed,
but water will be stored in ground tanks at appropriate locations along the 400 km
pipeline. It is further estimated that 50 000 people will be served with safe domestic
water supply and sanitation services.
Expected results
The transfer of 7 l/s of water from the Vaal and to deliver this to the villages in the
extreme southwest of the country through the Vaal‐Gamagara Water Transfer
Scheme.
Ongoing related activities in the Similar water transfer projects have been undertaken between Lesotho and South
region
Africa (Lesotho Highlands) as well as between Mozambique and Zimbabwe (Pungwe).
Description of national plan to the The Department of Water Affairs in Botswana will spearhead the project in
project
consultation with ORASECOM.
Status
The project can be considered to be in Phase 2 of the ICA Project Development
Phases.
Next steps
The next project development stage is a pre‐feasibility study to be completed in 2013.
This requires US$400 000. Thereafter, feasibility studies will be carried out in 2014.
Detailed designs and tendering for construction will be done in 2015. Implementation
and construction of the associated project components is expected to start in 2016
and will be completed in 2017.
Business model
Investment project financed as a BOT, grants or from loans.
Main parties in place
Department of Water Affairs, Botswana and ORASECOM
Main parties to be procured
Possible financier is KfW.
Project challenges
The major project challenges are the timely sourcing of project finances and possible
failure of Botswana to access the Orange‐Senqu waters due to lack of agreement with
other riparian states.

Intervention requiring financing
Project to be presented for grant financing during the planned 1st SADC Infrastructure
Investment Summit and Conference to be held in the last quarter of 2012.
Revenues for financing repayment This is an infrastructure investment project, which may not raise sufficient revenue to
repay any loans procured for implementing the project as the project can be
considered as a social project.
Estimated total cost
The estimated total project costs are US$175 million.
Execution period
After project funding is secured in 2012, the project will be undertaken from 2013 to
2017.
