Perhaps it's because January and February are normally so hot that I was surprised by the rain that we had today. I googled "cape town rainfall" and discovered a few sites showing that the Western Cape's historical rainfall is about 11mm in the month of January, increasing each month until it peaks at about 98mm in June, and then decreasing again to 13mm in December.

Our province experienced heavy water restrictions a couple of years ago and at the time it seemed as though everyone was installing well-points or bore-holes. I even tried to install one myself - this makes for an entertaining story. :)

At the time talk was going around that the government was considering placing restrictions, or perhaps levies, on the use of ground water for residential irrigation, due to the impact that the increased and uncontrolled use of ground water could have on the province's water table, and consequently on natural vegetation.
