The water filter

This is my water filter. There are many like it, but this one is mine.

My water filter is my best friend. It is my life. I must master it as I must master my life.

Without me, my water filter is empty. Without my water filter, I am thirsty. I must filter and chlorinate my water before drinking it. I must filter out dirt, sand, and parasites that are trying to give me giardiasis. I must chlorinate after filtration to kill any remaining viruses and bacteria.

Before the PCMO (Peace Corps Medical Officer), I swear this creed. My water filter and I are the defenders of my gastrointestinal health. We are the masters of our liquid consumption. We are the saviors of my life.

So be it, until clean water is mine and there is no dehydration, but my thirst is quenched!

In Madagascar, and I would venture to say all other Peace Corps countries, each Volunteer is given a water filter to use in preparing potable water. Within days of arriving in Madagascar, I was practicing safe water preparation and getting used to filling up my water filter every few days. It’s a relatively simple, yet vital, part of my experience and something that most of my readers might not be familiar with.

The water filter that I use consists of two chambers, one stacked on top of the other. After I get water from a local source (public pump, well, faucet, etc.), I pour it into the top chamber which contains two ceramic filters. As the water slowly gets filtered, it drips into the bottom chamber. The water in this reservoir is fairly clean, but still not ideal for drinking yet. This is because the ceramic candles are able to filter out macro-organisms, but there are rare micro-organisms that can still be present after filtration. The final step in the process is to chlorinate the water, essentially killing off any remaining harmful entities. For every liter of water, I must add 3 drops of chlorine.

With proper maintenance, this water filter will last for my entire length of service. I use it every day that I am at home for drinking water, cooking, and cleaning certain foods. When traveling, I take other water safety measures. This filtration system is highly effective and so far I haven’t been sick from contaminated water (knock on wood!).

While this is a great option for clean water at home, check out this video for another Peace Corps style DIY charcoal water filter.
