Why do people of the region you chose need a water purification system?

In Kenya most of the country is left without fresh water. Water pathogen is a huge health problem and people are left unprotected against parasites and epidemics such as cholera. The rate of exposure to harmful bacteria for Kenyan citizens is very high and water is contaminated at basin and pumps. Many water containers were previously used for oil, fertilizer, or wastes, which pass on many harmful chemicals without proper sanitation.

What is the biggest issue related to water facing the population?

Because there is not an equal amount of water distributed throughout the country people have to transport water long distances. Women and children spend one-third of their day fetching water. Also, due to the rapid population growth (2.6%), water scarcity will likely continue to be an issue as It has been for decades.

Small Scale Purification System: Water Filter Straw

The method by which the filtration straw works is that it has iodine chemicals in it that kill bacteria and filters and charcoal that help remove large particles in the water.

The cost is around $15 per straw and only needs to be replaced around once per year so there are no long term costs.

Benefits of the water filter straw are that it is convenient and very portable and can be used without replacement for a year.

Disadvantages of the straw are that it only serves a small amount of people, the water filtered can only be used for drinking, and it doesn't help with water accessibility.

Medium Scale Purification System: Natural Filtration

The reason the natural filter works is that the different layers and densities of the natural resources used serve as different types of filters for the water.

It costs around $50 and it likely needs to be replaced once a month, but depending on the region one may be able to find the material for the filters in nature.

Advantages of the natural filter are that it is environmentally friendly, it serves a good amount of people and, is not limited to drinking water.

Disadvantages are that it needs to be replaced frequently, it is not instantaneous and not guaranteed to kill all bacteria, just filter out larger particles in the water.

Large Scale Purification System: Boiling Tubs

The method by which the boiling tubs works is that the boiling of the water kills the bacteria and the filters used after the boiling help to remove large particles from the water.

It would likely cost between $1000- $5000, but the machine would not need to be replaced for decades but the only upkeep that would be needed is the replacement of the membrane filters and the cost of cleaning.

Benefits of the boiling tubs are that it is not limited to drinking water, mass quantities of water can be filtered at a time which can be sufficient for a entire village and it remove nearly all harmful bacteria.

Disadvantages are that the initial cost is expensive, there is potential danger with the upkeep and it would need to be cleaned often.
