The Vaalharts Irrigation Scheme is one of the largest irrigation schemes in the world covering 369.50 square kilometres in the Northern Cape Province of South Africa.
[1] Water from a diversion weir in the Vaal River, near Warrenton, flows through a 1,176 km long network of canals.
The blocks are divided into streets which have numbers that count up from the first one out.
To reference a specific plot, you take the plot number, follow it up with the block letter and then the street number.
