Kumulus Water is a Tunisia-born climate-tech company (based in Tunisia and France) that tries to deliver drinking water to water-scarce lands with an 'atmospheric water generator' making drinking water from moisture in the air. Its origin was in 2021, when Iheb Triki—an École Polytechnique graduate who had worked in renewable-energy investment—saw dew covering tents and cars one morning at a desert camp and realized 'there is water even in the desert.' With his friend Mohamed Ali Abid, who has motor-cooling expertise, he developed 'Amphore,' a device that recreates the morning-dew phenomenon by machine. It draws in and filters air, cools it to condense, adds minerals, and produces 20–30 liters of drinking water a day. It works where there is neither grid power nor piped water, at about $0.10 a liter—cheaper than bottled water. The first unit was installed, with Orange Foundation funding, at El Bayadha primary school in Tunisia's Jendouba governorate, which had no access to drinking water. As of 2020, 21% of Tunisia's population lacked safely managed drinking water.

+ before → after
The first Kumulus-1 was installed at El Bayadha primary school in a remote part of Tunisia's Jendouba governorate. According to principal Hassan Aoubdi, the school had no reliable access to drinking water. This device, making 20–30 liters of drinking water a day from air, was introduced with Orange Foundation funding, aiming to bring drinking water to children in classrooms without water.

- Kumulus reported making about 260,000 liters of water in 2023, cutting about 8,000 kg of CO2 and about 5,000 kg of plastic waste. The device won a water-category prize at VivaTech 2022 and was selected among the African Development Bank's (AfDB) top 15 promising GreenTech startups. About 100 units are operating, with about 3,000 liters a day drunk by about 2,000 people.P2 Independent evaluation (AfDB / VivaTech) / AfDB / Forbes Middle East

A second look
The core plus is drinking-water access in water-stressed areas and moving away from bottled water (People, Nature), independently backed by Reuters, The National, the African Development Bank (AfDB) and a water-category prize at VivaTech 2022. On the other hand, the number of units and people reached is still small-scale, and because a high share of devices is adopted via CSR and companies, the degree to which it reaches those most in need directly, and long-term maintenance and outcomes, are watch points.

How to read this assessment
- Reachable upper bound (ceiling): a confirmed − sets the ceiling, and independently verified + decide the position within it. + do not cancel out −.
- The weight of evidence is not symmetric: only confirmed − are counted; the volume of disputes or allegations goes under “Watching.” + are counted from independent evidence, while an organization’s own PR is treated as “reference.”
- Size is not value: scale is not used in the assessment. Matters that stay within money or competition—investors, shareholders, sanctions, trade secrets—are also excluded.
- The letter (assessment) and certainty (how reliable the information is) are separate axes.
This is a translation; the Japanese version is authoritative. The assessments here are generated automatically by AI based on published criteria. The operator does not alter individual results. Because they are AI-generated they may contain errors, and they are opinion and commentary, not statements of fact. Where evidence is insufficient, the entry is marked “On hold.” Requests for correction are accepted via the form.
Terms: Narrative Value = an assessment (A–G) of the distance between the story an organization tells and its reality / Ceiling meter = a visualization of the reachable upper bound / Watching = unconfirmed matters not counted / Protected stakeholders = people, animals, nature, and future generations. | Generated by: AI | As of: 2026-Q2 | Back to top
