OceanWell secures $11M in Series A to build deep-sea desalinization water farms

OceanWell, a water technology company, recently closed $11 million in Series A funding to scale its next-generation modular deep-sea water farm solution and launch California'’s water farm pilot with Las Virgenes Municipal Water District (LVMWD). Kubota Corporation, the family office of Jon Hemingway of Carrix Ports, and Charles McGarraugh, former head of metals trading at Goldman Sachs, participated in the round.

OceanWell is developing modular deep-sea water farms made up of pods that harness natural hydrostatic pressure at depths of 400 meters for reverse osmosis desalination. Each pod can produce up to one million gallons of fresh water daily, and the modular design allows for scalable projects based on demand.

This technology ensures ultra-clean water by filtering out salts, bacteria, viruses, pesticides, and PFAS, while its robust components are engineered for durability in harsh deep-sea environments. Unlike traditional desalination methods that are energy-intensive and threaten marine life, OceanWell’s technology reduces energy consumption by up to 40%, while protecting marine life and eliminating toxic brine disposal.

There is a rising mismatch between clean water supply and demand—with experts projecting that 5 billion people could be without clean drinking water by 2050. The problem is driven by rising demand for water in key economic sectors such as agriculture, industry and manufacturing and compounded by the effects of climate change such as drought and flooding. Since 1970 water demand has increased by 1.7x, while global supply has dropped by 50%. OceanWell aims to provide affordable, abundant freshwater with its deep-sea pods, which produce 1 million gallons per day of potable water each. OceanWell’s first water farm is being developed in its home state, California.

Earlier, the company completed prototype testing at the US Navy’s Deep Ocean Simulation Facility. OceanWell is supported by a working group of 24 state water authorities in California and aims to build 15 water farms across the globe.
