Thirst Relief is currently in the process of implementing the Haiti Filter Project. So far, Thirst Relief has provided a large power generator to an orphanage of about 130 children. The generator pumps water from their well to all water needs at the orphanage.

Donations to the Filter Project will help Thirst Relief implement Biosand Filters at the orphanage and throughout Haiti. The typical cost to fully implement a water project from the ground up is usually $10,000 USD.

Biosand Filter

The Biosand filter is an innovative version of the slow sand filter specifically designed for intermittent and/or household use. These filters are produced locally at the point of need using locally available materials and labor. The installed cost of each filter is $50-$90 depending upon location, with enough daily output of 99.9% pure drinking water to meet the needs of up to 20 people.

The Biosand filter is comprised of a concrete container (the approximate size of an office water cooler) with an inset plastic pipe, and filled with layers of sand and gravel. Contaminated water is poured into the top of the filter, where a diffuser plate distributes the water over the sand bed. The water travels through the sand bed, passes through multiple layers of gravel, and collects in the plastic pipe at the base of the filter. The clean water then exits the plastic piping for the user to collect.

The removal of waterborne pathogens and contaminants occurs in the Biosand filter due to a combination of biological degradation and mechanical filtration processes. The organic material present in the contaminated water is trapped at the surface of the sand bed, forming a biological layer, or "schmutzdecke", to actively remove the pathogens and contaminants. The water produced by the Biosand filter process is odorless, tasteless, clear in color, and safe for human consumption.

Haiti is the poorest country in the Western Hemisphere and has experienced a great deal of political violence throughout its history. On January 12, 2010, a 7.0 magnitude earthquake struck Haiti and devastated the capital city Port-au-Prince. Reportedly, more than 200,000 people were killed, although the exact number is unknown. Even before the 2010 earthquake, nearly half the causes of death have been attributed to HIV/AIDS, respiratory infections, meningitis and diarrheal diseases, including cholera and typhoid. According to the World Health Organization, 90% of Haiti�s children suffer from water-borne diseases and intestinal parasites.
