Tatirano Social Enterprise

Clean water for everyone in Madagascar


Madagascar is home to 26 million people, most of whom live in extreme poverty - on less than $1.90 USD a day. They can walk miles each day, through treacherous terrain, to retrieve water from streams and ponds that may be safe to drink one day and contaminated the next. If they are lucky, there is a reliable clean water source—but it can be located very far from home.

The United Nations has recognized the fundamental need for clean water in Sustainable Development Goal 6 (to ensure availability and sustainable management of water and sanitation for all by 2030). Our mission aligns directly with this: to bring clean water to everyone, everywhere in Madagascar.

We are a social enterprise called Tatirano, which in Malagasy means to “collect water.” A social enterprise exists first and foremost to bring about positive social change, like clean water to those that don't have it – and that's why we are here.

We aim to achieve a sustainable model whereby we can use the profits from private projects in tandem with donations to maximise our mission of clean water for everyone, everywhere in Madagascar.

Programmatic strategy

To achieve this we have established a multi-pronged approach based on three programmes:

  1. Our first programme is what we live for – social impact. We install rainwater harvesting systems in schools, in health clinics, in communities, and we might make a loss financially but we think it's worth it – especially since this programme usually targets those in the most need. At each system we set up sustainable models for management and maintenance that mean systems can contribute to paying someone to look after the systems and distribute water.
  2. Our second programme provides clean water on the doorstep for the first time – an affordable solution for people to have their own rainwater harvesting system at their homes. Using specialist equipment we manufacture our own low-cost, durable bladder tanks and install these at each home with the required guttering and fittings. In this programme we aim to cover our costs, without providing subsidies.
  3. Our final programme is what we hope will cover our costs sustainably in the future – profit making systems. These are aimed at wealthier individuals and private institutions such as hotels and office buildings. We want to maximise the profit here to share it with our social programme.
  4. We hope that by combining a traditional business model with social aims, we can be flexible, responsive and ultimately independent so that our organisation can always stand on its own two feet. This means that we will not only be able to install more and more systems to reach more people with clean water, but also that we can provide ongoing monitoring and support to ensure systems continue to work over time: clean water for everyone, everywhere, all of the time, in Madagascar.

    Rainwater harvesting

    Our simple rooftop collection systems send abundant rainfall to a tank with a tap. Instead of a potentially failure-prone filter, we use a ‘first flush’ mechanism to divert the first rain that runs off the dusty roof and gutters; self-cleansing to avoid contamination. We have found that our systems can provide water free from harmful bacteria and completely safe for consumption based on the World Health Organisation's guideline for drinking water quality. We continually make improvements to the design while keeping it simple and keeping costs as low as possible.

Harry Chaplin Director

Harry's passion of the weird and wonderful wildlife of Madagascar originally attracted him to the red island in 2011. Ever since that brief four week stint in the forests of the southeast, Harry has been using his engineering background to improve access to clean water for the people of Madagascar a bucket at a time. He setup a rainwater harvesting project in the rural southeast of Madagascar with SEED Madagascar before founding Tatirano Social Enterprise to enable long term access to clean water for everyone, everywhere.

Hasina won the Madagascar Presidential Scholarship in 2004 to pursue her education at Abilene Christian University in Abilene, Texas where she earned her Bachelor in Environmental Science. Ambitious to contribute to Madagascar's development, Hasina returned to her country and started working at the Presidency of Madagascar, before joining a nickel and cobalt mining company called Ambatovy, an international joint venture established in eastern Madagascar.

Hasina's passion for water, sanitation and hygiene emerged when she joined WaterAid in 2014. She took a year out from her time with WaterAid to study for her MSc in Environmental Management from Kingston University London under the prestigious Chevening Scholarship. Six years after joining WaterAid, Hasina is currently Advocacy Officer at WaterAid in Madagascar, supporting local governments and civil society organisations to realise everyone's rights to WASH.

EPP Andramanaka

Public school, 10,000 litres | Completed | 2019

Andramanaka is a large village of 1,700 people set a five-hour dirt-road ride away from Fort Dauphin. A 10,000 litre ferrocement rainwater harvesting system will collect nearly 240,000 litres of clean water each year. The tank is completely closed to outside contamination and each new rainfall event cleans the roof and gutters itself with the help of our simple ‘first flush’ systems – ensuring high quality water. The 300 students at the school will only use a fraction of the water available by the system, and so a community pay-as-you-use water kiosk was installed to share the surplus.

Centre Médical de Taolagnaro

Private clinic, 20,000 litres | Completed | 2019

This private hospital bases its philosophy on the story of Robin Hood – taking from the rich and sharing with the poor. We installed 20,000 litres of capacity across three rainwater harvesting systems with a total collecting potential of over 500,000 litres of clean water each year. With over 500 people passing through the centre each month, these water systems are providing a reliable clean water source to over 6000 people each year.

EPP Ambandrika

Public school, 20,000 litres | Completed

In 2016, SEED Madagascar installed two 10,000 litre plastic water tanks and accompanying rainwater collection system at a village primary school in Ambandrika, Sainte Luce. With the main aim of ensuring the 150 school children aged between 4 and 15 have water to drink and wash their hands.

SEED went on to install a gravity-fed pipeline to a community kiosk on the perimeter of the school grounds with the intention of sharing the water with the community. As of 2020, SEED have handed over responsibility of the management and maintenance of the community kiosk and rainwater harvesting system in general to Tatirano Social Enterprise. New management structures put in place will see a female Tatirano Agent employed to manage, maintain and sell the water to the local community. The revenue gained will contribute to the Agent's salary and to maintenance costs.

Upcoming projects

EPP Tanambao

Public school, 10,000 litres | Under construction | 2020

Work is underway at this school in the busy heart of Fort Dauphin. The project will include two 5,000 litre tanks, a handwashing station and a community water point.

Private household systems

Private households, 500 litres | Under Development | 2020

Our revolutionary bladder tank systems are currently in the testing phase at the Tatirano office. We hope to begin installing these in early 2020.
