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.

Madagascar: the facts

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.

    Our impact so far

    The social enterprise now manages RWH systems across the Regions of Anosy and Androy with a rainfall collection potential of 2,800,000 litres per year and a storage capacity of 350,000 litres.

    Thats 4,020 people each month that has access to clean water either for use at home or at school because of Tatirano Social Enterprise activities.

COVID-19 Response

23 handwashing stations | 325,000+ pairs of hands washed

After the WHO declared the coronavirus a global pandemic, Madagascar shut its borders to slow the spread. In response, Tatirano Social Enterprise transformed from a long-term development social enterprise to a humanitarian response. In close collaboration with the Mayor of Fort Dauphin, the Ministry of Public Health and the Ministry of WASH, and an overwhelming response to a crowdfunding page, Tatirano Social Enterprise established 23 handwashing stations throughout markets and busy areas of Fort Dauphin.

Handwashing stations were intentionally simple: three buckets, two cups, soap and water. To manage the stations, Tatirano Social Enterprise hired 75 primary school teachers, most of whom were unemployed due to school closures, and kept buckets full with rainwater from Tatirano Social Enterprise's school system at EPP Tanambao (below) via a bladder tank strapped to a cart. Over the 11 weeks the handwashing campaign has run so far, the project has recorded 325,000 handwashes. A steady 4,200 handwashes per day suggests a significant demand and understanding of hygiene practices and reinforces Tatirano Social Enterprise's fundamental aims of improving access to clean water to everyone, everywhere.

A change in aims and technique was required for Tatirano's first project in the arid region of Androy in the south of Madagascar. In a climate of limited rain across only a few short months, collection surface and storage for dry months is absolutely critical. This is why Tatirano's pilot in the Androy region is such a huge project.

Saint Vincent de Paul is part of the Catholic Church and houses a range of social projects. The water system, when completed, will provide a million litres of water per year for 995 school students between the ages of 3 and 25 years old; 75 handicapped Tsihombe residents who are fed on site every day; and 114 other people working on the site as teachers, constructors or as Sisters of the Church. Furthermore, a community kiosk will be installed at one of the storage tanks and a female Tatirano Agent will manage sale of water and maintenance of the systems.

As soon as Coronavirus travel restrictions are cleared, the team will return to finish the installation.

EPP Tanambao

Public school, 10,000 litres | Completed | 2020

Tanambao is one of the most densely populated neighbourhoods in Taolagnaro. The primary school has 1400 students from 3 years to 17 years old. In the absence of a reliable water source on site, students weren't washing hands, especially after using the toilet.

Linking up with Stop Hunger and other individual donors from Taolagnaro, Tatirano Social Enterprise installed two 5,000 litre water tanks with a collection potential of over 750,000 litres per year. With a clear surplus on the school's needs, a community kiosk was established to sell extra water to the local community. Our first Tatirano Agent, Madame Donine, manages the sale of water and the functioning the systems.

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 and is managed by our female Tatirano Agent, Rosseliane.

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 sharing the water with the community. As of 2020, SEED have handed over responsibility of rainwater harvesting system to Tatirano Social Enterprise. Tatirano's third female Tatirano Agent, Madame Harena, has been 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.

500 litres and 1000 litres | Affordable water at the home | zero subsidy, zero profit

The state-owned utility company, JIRAMA, is vastly under-resourced and as such, can only provide approximately 2/3 of Taolagnaro's daily demand when running at full capacity. Tatirano Social Enterprise has begun discussions and planning sessions to explore options of supporting this capacity at the municipal level with a future partnership very likely.

Meanwhile, Tatirano has manufactured affordable rainwater harvesting solutions for middle-income families to have control over their own water supply at home.

Upcoming projects

EPP Mananara II

Public school and community kiosk, 10,000 litres | Planned | 2020

The proven model of installing rainwater harvesting at a school and selling the surplus at a community kiosk will be replicated in this rural community. Work has been delayed due to the Coronavirus but work has now started and the project is due to be completed in late July 2020.

Lycée Pole

Public school, 20,000 litres | Planned | 2020

This secondary school system had been in the pipeline for nearly a year when Coronavirus immediately caused Peace Corps Volunteers to be evacuated from Madagascar and all grants were cancelled. Despite the drawback, the funding was still raised via private donors and the project will go ahead in early August 2020, bringing clean water to a school of over 1,300 students.
