Bacterial filtering plant – step 1
I work at Old Mutual at Mutualpark in Cape Town. It is a massive campus of several buildings serving about 10 000 people. To provide water for that many people requires about 450 000l water per day; that amounts to about 45l per person total (this is total consumption including the restaurants, kitchens, aircon units etc). So I think it’s a remarkable achievement that they managed to get the entire campus off the water grid by building an onsite world-class water recycling plant.
The main source of recycling water is waste water from the campus – yes every time you flush or wash your hands the output is recycled into drinking water, and its supplemented with grey water from the city (which then also goes through the filtration system). No city drinking water is needed.
Sand filtering – step 2
I was very lucky to go on a tour of the plant, and its impressive. It is capable of generating up to 800 000l water per day; that is almost double what is required on the campus. The water is super-clean, is tested everyday, and is compliant will the regular legal requirements (SANS 241 to be specific). It is the first privately developed waste water filtration plant in South Africa and can supply water to the campus without any clean municipal water required. None at all!
Reverse osmosis – step 3
Note: I mentioned 3 steps but that is massively simplified; it is a complex multi-step filtration system they use.
So between the solar panels, waste recycling and now water recycling I think they are doing a good job with the environment. And it makes business sense. The water plant will only need a few years to pay for itself. This is what large companies should be doing.
I might have to write a series on the street art in Muizenberg, because I am finding more and more walls with really interesting art painted on them. I drove past this wall the other day, and it was covered in Escherish sharks. I think it is remarkable. The artist’s phone number is in the corner if you want you own wall painted.
Just look at this beautiful library. Doesn’t it make you wants to browse those shelves to find a good book, pour yourself a good brandy, and to sit quietly and disappear in a good book.
I took this photo of this old tree a few years ago, but I love the textures in the photo, and the contrast between the smooth mist and the gnarled bark and sharp edges of the tree.
Vegetable farm workers in Philippi. With the exception of the tractor, these farmers still follow a very manual, labour-intensive method of farming. It is not through choice, but rather through the simple fact that in South Africa that labour is cheap, but equipment is very expensive, making it almost impossible for the small farmers like this to modernise their operations.
This area is very much in the press at the moment; there is a debate as to whether to keep using the land for farming, or to start building on it.
