Hi Maggot!

Really, despite the rat-tailed maggots, it's not necessary to sterilise Cape Town tap water. Drinking water in Cape Town meets South African Bureau of Standards specifications, which are also World Health Organisation standards (OK: somepeople would argue that these standards aren't stringent enough!), and is tested regularly. If you’re concerned about it, though, you can ask City of Cape Town for the results of tests on drinking water in your area.

One thing I would suggest is that as a general rule it's better to only drink water from the cold tap; sometimes nasty things can get into hot water tanks and cisterns if they're poorly maintained.

If you still feel unhappy about it though, and do want to sterilise your drinking water, then yes: boiling it, in the kettle or on the stove will absolutely do the trick! It's also fine to drink it once it's cooled down. Store such drinking water in the fridge, and change it every few days.
