Project Tatirano

Project Tatirano - which means ‘to collect water’ in Malagasy - is improving access to clean drinking water via rainwater harvesting in the Anosy Region, southeast Madagascar.

For millions of people around the globe unable to access clean sources, consumption of contaminated water includes digestion of parasites. These generally lead to diarrhoea, and in Madagascar, where just 35% of the rural population has access to an improved water source (UNICEF, 2014), over 2,000 children die each year from associated illnesses. The tragedy in their deaths lies in the simplicity of the solution: access to clean, improved water.

The water from Tatirano is very clean, better than the river where I was collecting before, so I use it for drinking, cooking and washing. When it is raining a lot, my neighbours come and collect water too

Whilst rainfall in the Anosy region is relatively high, rainwater harvesting is not widely practiced. This simple technique provides large volumes of clean water, has substantial health benefits, eliminates the costs associated with water collection and allows more time for educational, social and entrepreneurial activities.

A 20,000-litre capacity system on the roof Ambandrika primary school provides for 144 school children every school day and 750 members of the community up to four times a week, dependent on water supply and functionality of the ‘Tatirano Management committee; a community-elected committee that manages the system.

As a result of not drawing water anymore, I am able to take proper care of my family and I am using the time for weaving. I weave one mat or five baskets every day.

So far we have installed 148 household systems across Anosy. Families enrolled have already reported benefits including more time to create marketable goods; more time spent caring for young children; savings from not paying expensive water collectors; and physical health benefits from not carrying heavy water loads for long periods of time.

We are planning to install more school systems as the word has spread from the first school system and water surpluses can be used for community use. We're using the Calabash Tank Manual to build simple, durable and cost-effective ferrocement tanks in rural schools across Anosy.
