Got mine down from 22KL to 13KL.
Household of 4. I don't think I can cut down much more than that. My opposite neighbour has a well point and hit water at about 3 meters. I'm thinking of putting one in before the end of the year.

Im getting a well point drilled this friday. They stop at 12m so 2 options; 9 meters or 12 meters but if I can give advice, dont let them stop at 3m although you live very close to the Lourensford river. I have heard from many people that due to the drought the 3m points dry up quickly unless there is enough rain.
I told my guy to go down to 12m and I want the 1.1kw pump just to be certain.
I'm waiting to do it in summer when the water table is lower and was planning on going about 6 to 9m. Price quoted for 12m and pump?
Who you using? Do they come out to Somerset West? PM his contact details please.
Reply to all of the above - Cape Flats Aquifer and Well Points.
Other than the Table Mountain Group Aquifer which is the 1000 Km Aquifer that stretches between Vanrynsdorp and Port Elizabeth we have the most amazing Cape Flats Aquifer which is truly a marvel of nature.
Until recently I had never researched information about our Aquifer but last week my wife attended a talk held by one of the top guys in this field and he had only amazing things to say. Did you know that the Cape Flats Aquifer level does not drop and that it starts as far North as Atlantis or even Malmesbury and sweeps down towards Melkbos and then across to Bellville and then down over the entire Cape Flats, with water topping up from both sides of the Cape Flats from the two Mountain Ranges on either side of the Metropole and ends at False Bay and with the opposing force of the sea holding it up at that point. The expert added that because the Cape Flats is made up of dense sand, this will also lend itself to every drop of rain that enters the sand actually going into the Aquifer too.
My personal view is that obviously all the water doesn't go in to the sand as there are roads and stormwater drains but I got his point, whatever lands on open land or runs off roads into the earth goes straight towards topping up the Aquifer. The Cape Flats Aquifer is a marvel of nature and we are lucky to have it.
In regards to the depth the well point, in my case we went to about 13 meters (although the actual water level is between 1 and 2 meters) and then hit a hardish clay of sorts which would be difficult to penetrate with just blowing water, so we left the pipe just above this level. Also from what I understand is that the pump of a well point can only suck up from above ground to a level of around 15 meters, thereafter you need to start drilling and installing a borehole with a submersible pump.
The Cape Flats Aquifer, the relief to the gardeners of the Cape Metropolis. Use it and keep Cape Town green and beautiful.
