Do you have access to a reliable source of safe drinking water?
In many regions where seawater desalination is not available and lakes, rivers and groundwater wells are depleted, extracting water from the air can be a more convenient and economical solution than paying for water truck deliveries. Especially for house owners not connected to a public water network.
After 4 years of research and development, we are now launching the Aquahara Water Pavilion, the most efficient solar water generator, producing around 200 liters (52 gallons) of water per day through all seasons with just over 100 m² (1000 sq. ft.) of solar collectors. This is sufficient to supply water to your whole house and makes you independent from unreliable water sources.
The Aquahara Water Pavilion uses a fully renewable and highly efficient process with a concentrated salt solution to extract water from the air even in a dry desert climate. It does not require any external power. And the best: the water is pure and tastes great.
Instead of wasting energy to cool the air like conventional devices, we absorb moisture from the air in a salty liquid. Just like in a saltshaker that gets sticky, salt pulls water out of the air without cooling it, even if the air is very dry. The salty liquid is pumped from the absorber into a distillation unit, where it is heated using solar energy to extract water vapor and is then returned to the absorber to restart the cycle.
So, we built a liquid desiccant dehumidifier. What is so special about our system?
Yes! The Aquahara Water Pavilion uses a distillation process to extract pure water vapor out of a salty solution. The very high salt concentration kills bacteria and viruses, and pollutants that may have been in the air stay in the liquid and are not condensed with the water vapor. We add minerals to the distilled water to achieve an excellent taste, just like mineral water. Once the mineralized water is in our storage tank, we use UV light to keep it sterile until you drink it.
Yes, it is! Aquahara Water Pavilions are not meant to replace seawater desalination systems. But we offer a solution for house owners and communities who live in a region where seawater desalination is not available.
Yes, in many regions, it is! But in many other regions, drilling a new well is prohibited or ground water levels are depleted such that wells are no longer a sustainable water source.
You could, but this is not economic. Our water is better used for the purpose of drinking and sanitation and to supply water to your house or your community.
Aquahara Water Pavilions are completely autonomous and do not need any external power supply. The solar thermal collectors and photovoltaic modules are part of our system and included in the price.
Even very dry desert air still contains at least 7 ml of water per cubic meter of air. The process developed by Aquahara extracts about 1 ml of water per cubic meter of air under desert conditions. To put this into perspective: if you spread your arms and walk for 1 minute, enough air will have flown around your body to extract one glass of water. This is thanks to the highly concentrated and environmentally friendly salt solution we are using. Salt ions are charged particles and their electrical force attracts the water molecules out of the air. By the way, the salt solution flows in a closed circuit and is not leaving the system, so we do not have to replenish nor replace nor discard the salt and the system is completely autonomous.
An Aquahara Water Pavilion, including its roof with the solar collectors, needs a surface area of 14,5 x 7,5 meters (48 ft x 23 ft). It produces around 200 liters (52 gallons) of water per day. This is the standard system size that we are currently offering. If you want to produce more water, you can just buy multiple such units. If you need a smaller system, please check our website in the future.
Aquahara is now accepting reservations from customers from Southern Europe and the USA. We will produce and ship systems in the order in which we receive the reservations.
Manufacturing will start in Q4 2021 as soon as enough reservations have been registered and shipping will start in Q1 2022 as soon we have obtained formal product approvals from federal and state authorities.
You should have a need for at least 200 liters of water per day, for example to supply water to your house if you have no connection to the public water network and your current water well is no longer providing enough water.
An Aquahara Water Pavilion requires at least 14,5 x 7,5 meters (48 ft x 23 ft) of free unshaded space on your property for the solar collectors, which are included in the price and put on a roof on top of our Pavilion. In the future, we may offer to put collectors on your own house roof to save space, but this option is not available yet.
If you are interested, please complete the pricing information form here below. You will receive an automated email with more detailed information including pricing and including a link to our online reservation form. If you decide to make a reservation, this will be non-binding and free of charge. When our production starts, we will send you a formal purchase contract; at that point, you will have to make your binding purchase decision within 3 weeks.
Yes , we will offer a product warranty according to federal and local regulations.
During the last 4 years, we have built and tested multiple prototypes with a relentless focus on reducing the cost of atmospheric water production under dry air conditions. We are now completing the first pilot customer system with a water production capacity of 200 liters per day in a children’s village south of Marrakech in Morocco. After obtaining official approval from the Moroccan authorities, the village will use the water for drinking and cooking, which will reduce their monthly costs of purchasing mineral water in plastic bottles. A preview of this system with drawings and photographs will be published as a video sequence on this website. Once the system is operational, we will provide more video material and welcome visitors on site. With this first pilot system, we are ready to launch our system on the market for pilot customers.
After launching our Aquahara Water Pavilion in Southern Europe and the USA, we want to continue reducing the cost of our system with series manufacturing, volume contracts with our suppliers, and additional engineering improvements. When we have sufficiently lowered the cost, we will launch our system in development countries (the “Global South”). People will be able to buy clean water using a prepaid tag or card. The Aquahara water will cost less than their current alternatives. Customers will not need a smartphone or an internet connection. They can recharge their prepaid tag or card using cash at a local shop; the shop owner uses her/his smartphone to credit the money to the account of the company operating the Aquahara system.
