Hydropanels Bring Water to Navajo Nation

In the Navajo Nation, sometimes a single spigot on an empty road is the only water source around for hundreds of residents. Others have to drive from their rural homes into towns miles away to buy all the water they need for cooking, drinking, cleaning, and livestock, because there's no infrastructure to bring it through pipes. About 40% of households in the Navajo Nation live without running water. But now, at a few houses, panels positioned on the ground pull moisture from the air, connecting to a tap inside the home and providing up to 10 liters of water -- or about 20 16-ounce bottles -- a day, at no cost to the family.

The panels come from Zero Mass Water; the company's Source hydropanels use sunlight to absorb water vapor from the air, even in arid climates. Zero Mass Water partnered with local Navajo governments and Navajo Power, a public benefit corporation working to install solar panels on tribal lands, for an initial demonstration project in which 15 homes received two Source panels each, for a total of 30 panels. Those initial panels were funded by Barclays and The Unreasonable Group, an accelerator for socially minded startups.

Each Source hydropanel can make up to 3 to 5 liters of water a day; with two panels, a home can get up to 10 liters a day, and each panel can store 30 liters of water, or 60 16-ounce bottles of water, for when cloud cover may affect production. The panels last for 15 years.

The Navajo Nation has at points during the pandemic had the highest COVID-19 infection rate per capita in the U.S., worsened by the fact that residents can't easily access water to wash their hands and have to make frequent trips into town to buy water. Zero Mass Water first started communicating with the Navajo Nation about three years ago, but the pandemic has heightened the urgency for this partnership. The company worked with chapter leaders -- the Navajo Nation has 110 chapters, which are geographical divisions like counties -- to find the people most in need.
