Light weight, rapidly deployable, and wave-powered - fresh water for a greener future

Water Bros Desalination, LLC. is developing the next generation of emergency response, wave energy harnessing, and water delivery systems for remote coastal and islanded regions for a sustainable and affordable future. Harnessing wave energy in near-coastal and islanded communities is key to reducing dependence on fossil fuels for water production.

April 5, 2022 - Teams Oneka and Water Bros retrieve their desalination devices after strong winds and waves contributed to an unplanned conclusion of the Waves to Water Prize DRINK Finale. Devices from two competitors broke free from their tethers, and two others were forced to the edge of Jennette’s Pier in North Carolina’s Outer Banks, where the competition was taking place.

April 4, 2022 - Strong wind and waves overnight contributed to an unplanned conclusion of the Waves to Water Prize DRINK Finale, as two devices broke free from their tethers, and two others were forced to the edge of Jennette’s Pier in North Carolina’s Outer Banks, where the competition was taking place. Teams spent part of the day surveying the situation, preparing for the next day’s recovery. (Photo by Werner Slocum / NREL)

Our Technology

Our design utilizes commercial off-the-shelf (COTS) components to the maximum extent to develop a heave based buoy that converts the linear motion of irregular wave energy to rotational energy to drive dual, brine pressure-assisted, positive displacement piston-style pumps to operate two separate reverse osmosis systems. This system redundancy allows fine-tuning of the gearing ratio based on the wave energy available at the deployment site and continued operation of the device even if one side of the energy harvesting system fails.

The design is specifically designed to be deployed,
operated, and maintained anywhere in the world with only a modest set of basic mechanics
tools and locally available replacement parts. This design ensures the longevity of the device even in the remotest corners of the world.
