Exit point of the Orange-Fish Tunnel near Teebus

[Bobby Stodel]

On my way from the Ben10 to Cape Town via the Mountain Zebra NP in May I will pass close to the abandoned village of Teebus.

I understand the exit of the Orange-Fish Tunnel lies nearby between the Teebus and Koffiebus Koppies.

 

Has anyone visited the outlet of the tunnel?

Is it accessible?

I can see on T4A that a road crosses the Teebus River between the Koppies but is this the location of the tunnel end?

 

On the map about a kilometre from the road crossing the river the thickness of the river doubles which might indicate the place where the tunnel ends and the water from the tunnel dramatically increases the water volume.

Unless there is a path from the road to that place it will be very difficult to get there.

But presumably some maintenance checks are carried out and so the end of the tunnel should be accessible?

Hi Bobby,
Sticking 

Show on a map where the start and end-points of the Orange River and Fish River tunnel is, and if it is publicly accessible

Into Google gives this response.

Hope it helps.

The Orange-Fish River Tunnel is an 82.8 km (51.4 miles) long underground aqueduct in South Africa that diverts water from the Gariep Dam to the Fish River valley for irrigation and industrial use

Public Accessibility 

• General Area: The intake tower at Oviston is a known landmark on the Gariep Dam.
• Inside the Tunnel: The tunnel is generally not open to the public.
• Special Access: It is occasionally opened to the public for a few weeks a year during maintenance (usually in mid-winter), when water flow is stopped. During these times, visits are usually managed for guided tours.
• Observation: You can view the outlet canal at Teebus where the water emerges. 

The tunnel is considered an engineering marvel and was, at the time of completion, the second longest water supply tunnel in the world.

Hi there

 

Yes I have, but on official business. The outlet is not open to the public. I am not sure whether an individual can arrange a visit beforehand, but doubt it.
