What a roof actually yields

A roof gives you one litre for every square metre it covers, for every millimetre of rain that lands on it — less about a tenth that the gutters, the wind and the first flush take off the top. A 180 m² house here in Worcester, on our long-run average of 240 mm, is somewhere near 39 000 litres a year. That is more than most households put on the garden between October and March. Robertson and Montagu sit close to the same figure, Villiersdorp and Grabouw are double it, and a shed roof in the Koue Bokkeveld can fill a 10 000 litre tank twice in a single winter. We size against your roof and your rainfall, not against a page in a catalogue, and we will say so when a second tank is money you do not need to spend.

From gutter to tap

The job starts at the gutter and ends at a tap you can drink from. A rainhead goes on at the top of the downpipe so leaves and thatch never reach the tank, a first-flush diverter dumps the dirty opening litres of a storm and empties itself before the next one, and the tank stands on a levelled pad or a galvanised stand if you would rather gravity did the work than a pump. After that it is a pressure pump, a three-stage filter on a bracket, and a changeover valve so the house goes back onto municipal water without anybody inside noticing. Two teams work out of the yard on Durban Street: one stays in the Breede Valley, the other goes down the R43 through Villiersdorp into the Overberg on a Tuesday. A standard house is a day and a half, and we take the old gutters away with us.

The first storm of the season is the one that matters

It carries the most dust off the roof and the most water behind it. If the diverter is not fitted by the end of April you spend the whole winter filtering what should have gone down the drain.
