Tunnel-chamber

Operation of a tunnel-chamber (anti-theft chamber).

Motetema, Limpopo Province, South Africa - Client : Sekhukhune Farmers Development Trust - Designed and built by Dams for Africa, February 2004

(1) The anti-theft chamber in its closed and locked position. The borehole pump is started
by means of the switch on the outside.

(2) Using a special opening tool the tunnel can be lifted up and wheel-assemblies may be inserted into the sides of the tunnel.

(3) The tunnel may now be pushed backwards until the chamber is fully open, allowing access to the borehole, pump and motor - if maintenance is required.

4) The tunnel-chamber protects the borehole/motor/
pump and this ensures that the crop can be systematically watered - even in dry conditions. The
cost of such a chamber is insignificant in relation to the market value of the crop.
