Save Water

How to save water in Cape Town…

The usual answer:

  • Shower less and keep it quick.
  • Flush toilets only when needed.
  • Minimise laundry.

If everybody who lives in an apartment does the above, we might save up to 6% of our water resource. Hmm. Not that much of an impact? Yeah, sadly.

The total percentage of water that ends up in our homes is only 19%.

Solution:

  1. Cut down on outdoor water use.
  2. Fix the 20% of leaks that cause the most waste.
  3. Figure out some form of tax on commercial and agricultural water use, to incentivise optimal use.
  4. Rethink agriculture. Create aquaponic urban / rooftop farms.
  5. Build more dams since Cape Town water demand will probably surpass supply by 2020, even if climate change does not impact us.
  6. Reduce evaporation from our existing dams. Cover dams with solar panels maybe.
  7. Make sure the stuff we do grow and export is high value and healthy. Don’t grow soy to feed chickens to make KFC.
  8. Bonus item / global context: Eat less meat. Support aquaculture projects. Drink less coffee.

Lastly, don’t feel so bad about showering.

btw. I had to hack together some numbers from a few data sources. Could be out a bit. If you have better data, let me know.

Data:

GreenCape report. Seems the Cape Town water distribution network wastes about 15% (well below the 37% national average).
