Examples of Completed Projects By Our Team Members

With a large share of our Cameroon project efforts coming from our partner, ACREST, the following projects they have completed gives some wonderful examples of projects that are making a huge impact in Cameroon.


ACREST' staff received biogas construction training from a Kenyan expert.


Building of a Digester, Digester Dome, Expension Chamber, and hook for flame dispersment.

Building Digester and Dome-----Building Expension Chamber

Expension Chamber------------Flame and Flame Use



Investment:  $10,000


Impact:  50 Families have new gas source every day for cooking.

Biosand Filter

After receiving a training from expert of the Centre for Affordable Water and sanitation Technology ACREST staff have started manufacturing biosand filters for safe water.


ACREST produces 2 biosand filters per day.


Physical Need:

There is an undeniable need for clean water throughout the developing world.   Every year there are over a million deaths related to unsafe water, sanitation and hygiene,mainly through infectious diarrhea.
Over 1.1 billion people lack access to clean water and even more lack access to proper root sanitation.


Physical Need:   The BioSand filter is one of several household water treatment technology options.

Household water treatment is important to ensure an improved quality of water, because it allows for the water to be treated at
the ‘point of use’.


The BioSand filter is an innovation on traditional slow sand water filters. It allows for intermittent operation at a household level.
The filter can be constructed locally anywhere in the world because it is built using materials that are readily available.


It is simply a concrete container, enclosing layers of sand and gravel whose purpose is to eliminate sediments,pathogens and other impurities from the water.


The BioSand Filter is proven to almost entirely remove the disease-causing organisms found in water. It removes 100% of parasites
and over 95% of bacteria. It also removes nearly all suspended sediments, and is capable of removing significant amounts of organic
and some inorganic compounds.




Physical Investment:  $15,000


Physical IMPACT:  Clean Water for local residents.

Wind Energy

The majority of windmills introduced in Africa are high-tech and very expensive. These mills are generally used for pumping water, and in some cases for producing electricity.  In coastal and mountain areas, harnessing the abundant wind energy for irrigation is an efficient way to fight droughts, and increase food production.

In Africa, wind power could play a useful role for water supply and irrigation (wind pumps) and electrical generation (wind turbines or generators).  Wind power is a mature renewable energy technology that could be used for small and large-scale electricity generation.  There is substantial potential for deployment of this technology in Africa, especially along the coastal and mountain areas.                                      Wind Power for Water photo(right)
