Large Scale Water Generator

Watergen’s Large Scale unit is an industrial scale Atmospheric Water Generator (AWG)

Requiring no infrastructure but electricity, the Large Scale system is literally a plug-and-drink solution, aimed for schools, hospitals, commercial/residential buildings, whole villages, factories and off-grid settlements, providing a robust and renewable source for fresh, clean drinking water.

The LS can service millions around the world, eliminating their need to “hunt” for water every day, providing water independence and social stability.

The Large Scale system has a multi-barrier air filtration cascade, ensuring high-quality water generation regardless of the air quality, and a built-in water reservoir and treatment facility, continuously circulating the water, keeping it fresh over time.

Solution for cities

A family requires only 20 liters per day for drinking while the average overall water consumption of a family can reach 300–500 liters per day (for showers, laundry, and dishwashing).

In cities or areas where the municipal water system is either not safe for drinking or the water quality is inconsistent, Watergen’s Large Scale solution offers a water source separation concept.

Installing a Large Scale unit on roof-tops of commercial or residential buildings creates safe and renewable local drinking water reservoirs, directly servicing each building using a simple and independent water infrastructure system that delivers fresh drinking water directly to the family’s kitchen sink, while using the municipal water for all other uses.

This concept, if adopted on a wide scale, offers decentralization of the city’s water infrastructure, creating independent citywide renewable water reservoirs.


Large scale water generation at night

In most countries, during the night, electricity costs plummet due to off-peak rates.

Atmospheric conditions are also preferable for water generation, because the air is colder with higher relative humidity, requiring less energy to extract.

Selectively operating Watergen’s Large Scale AWG during the night creates a dual synergy that can drastically reduce water generation costs.

A modular and scalable solution

The Large Scale systems are built as modular units, enabling fast and easy integration of multiple units together into water generation farms, to facilitate growing and changing water requirements.

Several Large Scale units can be fitted in one container, facilitating fast and easy transportation.

  • Two LS systems can easily fit into a 20’ container, four into 40′ container
  • Estimated water production: ~ 12,000L/day for 20′ / ~ 24,000L/day  for 40′
