Individualise water filtration

ORISA® sustainable equipment

We have developed a water filtration solution based on an approach that is both community-based and individualized. Our water purifier makes people autonomous when it comes to water treatment.
In this way, they can filter the water and meet their basic needs - food, water, hand-washing, etc. - with healthy water that stops the spread of water-borne diseases.
This approach makes it possible to act in humanitarian emergencies (epidemics, health, malnutrition, climatic disasters, conflicts).

It is just as relevant for humanitarian development (home filtration in rural areas or transhumance, education, clinics and health centers, etc.).

Recognised, tried and tested solutions

  • 20000

    ORISA® water purifiers deployed in humanitarian contexts as part of emergency or development programmes aimed at saving lives or improving the living conditions of populations living in precarious conditions.

  • +200000

    people affected by our solutions who have sustainable access to clean water or who have benefited from filtered water as part of an emergency humanitarian response.

  • 50

    countries concerned by the deployment of ORISA® water filtration equipment, mainly in Africa (Chad, Madagascar, Burkina Faso, etc.) and Latin and Central America (Colombia, Haiti, etc.).

  • 6

    NGO partners in the development of the ORISA® specification, which is one of the most appropriate solutions for humanitarian use, as demonstrated by the WHO's Household Water Treatment Technology Assessment Programme (HWTS round III).

A filtration system approved by international aid players.

Solidity, mobility, durability, autonomy: these are the main advantages of our ORISA® water purifier, as well as being formidable when it comes to reducing water-borne diseases. To ensure the performance and adaptability of our ORISA® water filtration equipment in humanitarian contexts, we designed it in response to specifications drawn up with major French and international NGOs: Médecins sans Frontières, the French Red Cross, Solidarités International, Médecins du Monde, Handicap International, Terres des Hommes Lausanne and Premières Urgences.

A guarantee of adaptability and a humanitarian guarantee unrivalled on the market.

We have developed solutions tailored to humanitarian emergencies as well as to rural development needs and access to water for transhumant populations, extending the work of NGOs. We guarantee sustainable benefits over time by changing the paradigm of access to drinking water, from dependence to autonomy.


ORISA® water purifier

ORISA® is a high-performance water purifier that filters rainwater, surface water (streams, rivers, lakes, ponds) and groundwater (water tables, wells). It eliminates microbiological contamination (bacteria, viruses, micro-organisms and parasites such as protozoa), as well as microplastics, sediments and other suspended matter present in the water to limit waterborne diseases.

  • Manual ultrafiltration on demand
  • Portable system: 2kg and 42.5cm
  • Robust and safe
  • Up to 3L/min
  • 20,000L of water per ultrafiltration membrane
  • LOG 8 - 99.999999% efficiency: bacteria and protozoa
  • LOG 5 - 99.999% efficiency: viruses
  • Turbidity peaks eliminated from 1 to 250 NTU
  • Innovative integrated cleaning in less than 30 seconds
  • Equipment can be dismantled and repaired

"Full protection: three stars"

ORISA® approved by the WHO

ORISA® has been tested as part of the World Health Organisation's (WHO) international assessment programme for domestic water treatment technologies (HWTS round III). It was found to have the maximum performance level of "Complete protection: three stars".

Feedback from client NGOs

Following humanitarian projects, NGOs such as Solidarités International and Acted, as well as smaller associations such as Echanges France Cameroun, have shared their experiences of deploying ORISA® water purifiers.

Humanitarian feedback

Preserving the health of every human being

2.2 billion people have no access to drinking water.
A scourge that leads to
deaths, health problems and unacceptable inequalities, even though access to clean water is a fundamental right.

This alarming fact is the basis of our mission.


Support your humanitarian missions

Thousands of NGOs deploy our purifiers around the world.

Epidemics, malnutrition, conflicts, education, etc., humanitarian contexts that are based on different challenges and communities with specific lifestyles.

Chad, Colombia, Ukraine, Madagascar, etc. Deployment areas with diverse local characteristics.

The same durable, reliable, high-performance filtration equipment is available for a wide range of situations, making it easy for humanitarian workers in the field to deploy and for beneficiaries of humanitarian programmes to get to grips with, thanks to our technical documentation and training courses.

How does ORISA® support humanitarian action?

Individualise water filtration for the whole family

ORISA® is a high-performance water purifier that allows users to collect rainwater, surface water and groundwater and filter it. By simply pumping the water by hand, they can purify it independently and avoid the risks of water-borne diseases.

Taking action for the health of vulnerable populations

ORISA® filters out microbiological contamination such as bacteria, viruses, micro-organisms and protozoa, as well as microplastics, sediments and other suspended matter present in water. ORISA® technology works by mechanically filtering impurities: ultrafiltration technology.

Combating water-borne diseases

ORISA® protects the health of its users and reduces water-borne diseases such as cholera, dengue fever, diarrhoea, scabies, hepatitis A, hepatitis E, malnutrition, onchocerciasis, malaria, schistosomiasis, trachoma and typhoid and paratyphoid fevers.

Supporting beneficiaries over the long term

Designed without programmed obsolescence, the mission of the ORISA® purifier is to bring autonomy and dignity to beneficiaries over the long term. This is why we have chosen low-tech, energy-free water filtration equipment. Its main maintenance relies on integrated, autonomous cleaning, and repairs are possible thanks to the availability of replacement filtration systems and spare parts.
