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

Roossenekal, Mpumalanga, South Africa - Client : Bethal Farmers Association / Eskom Development Foundation - Designed and built by Dams for Africa, Aug 2003

(1) The anti-theft chamber in its closed position. The opening tool is in view.

(2) Using the opening tool the roof-slab (lid) can be lifted out and then turned through 90 degrees.

(3) After the four wheel assemblies have been inserted into
the sides of the roof-slab, the lifting tool is screwed out of the cone shape bush. In this process the wheels of the roof-slab come to rest on the rails.

(4) The roof-slab may now be pushed to the back end of the chamber.

(5) A view of the electrical control panel tucked in next to the borehole. The control panel may be lifted out if maintenance needs to be done on the switches inside.

(6) A view of the irrigation pump at the other end of the chamber.
