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%.
- Cut down on outdoor water use.
- Fix the 20% of leaks that cause the most waste.
- Figure out some form of tax on commercial and agricultural water use, to incentivise optimal use.
- Rethink agriculture. Create aquaponic urban / rooftop farms.
- Build more dams since Cape Town water demand will probably surpass supply by 2020, even if climate change does not impact us.
- Reduce evaporation from our existing dams. Cover dams with solar panels maybe.
- Make sure the stuff we do grow and export is high value and healthy. Don’t grow soy to feed chickens to make KFC.
- 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.
GreenCape report. Seems the Cape Town water distribution network wastes about 15% (well below the 37% national average).
