Thanks. I haven't been able to find any low energy distillers and since I'm not on clean energy that option is off the table for now. I'll probably pick up an osmosis filter and bring back next time I travel.
What's the nature of the contamination?

Don't know. Probably nothing too serious although authorities recommend to avoid drinking it after heavy rainfall.

Sounds like microbial or sewage contamination from storm water overflow. In that case, a slow sand filter should be fine. It's cheap, can be made with locally sourced material, and should be adequate to remove biological contaminants. It's a fairly easy DIY project.

Having to bring a large and expensive R.O. machine back seems like overkill and probably more trouble.

Use a large water-tight container with a spigot at (or near) the bottom. A used 55 gallon plastic drum should do it (blue are food grade IIRC). You'll just need the plumbing parts then.
On the bottom goes clean gravel to above the spigot level, then coarse sand or fine gravel, then finer sand on the top. The middle layer of fine gravel or coarse sand keeps the sand from falling into your gravel at the bottom. The top of the sand forms a bio-film which absorbs contaminants.
You also need a drain at the top right above the sand you can use to clean it every few weeks when it slows down (you stir up the layer then drain the cloudy water and use to water plants or something).

It'll be around a thousand pounds, so make sure it will be somewhere it won't create a surcharge on the soil by your foundation, particularly if you have a basement.
As the name suggests it's slow, but it's easy to make enough water for drinking purposes. If it works well you could rig a few pipes or tube to carry the clean water to a container and a float to auto-fill the top when it gets low.

@Jebus
This site has some good images:

It's about roof water harvesting rather than unclean tap water, but similar principles.
Interesting recommendations on UV sanitization. Also, if your tap water is chlorinated it could affect slow sand efficacy by killing the good microbes

@brimstoneSalad Thanks for this information. I am not very handy but labor is cheap down here so it's definitely worth looking in to.

If I were in your position I'd have my house totally tricked out. Rain water harvesting (if it rains a lot there), greywater system, solar water heating. Anything environmentally friendly that would save money.
