Wave – Powered Sustainable Desalination Solution

Water scarcity is among the greatest challenges of the 21st
century. Oneka has an extensive mission: making the oceans a
sustainable, accessible and affordable source of freshwater.

What we do

We combine the ocean’s seawater with its own wave energy to provide freshwater to coastal populations & industries without compromising the environment.

Our solution increases resilience to climate change while reducing greenhouse gas emissions and water costs.

The Benefits

All-in-one solution

Oneka offers an all-in-one desalination system. Everything needed to produce drinking water from seawater is included on the buoys positioned at sea. This includes offshore pumping through filters and reverse osmosis membranes to obtain high quality drinking water. The buoys are designed for limited and simple maintenance.

Zero CO2 emissions

By using our solution rather than conventional systems powered by gas and electricity, we avoid emitting significant amounts of greenhouse gasses. Each Iceberg-class buoy installed saves about 100,000 kg of CO2 per year, equivalent to 20 to 30 cars off the road.

Zero electricity

The Oneka system does not require electricity, fuel or solar panels. Only waves of decent height are required to produce drinking water. By choosing Oneka as your water supplier, you can save on your water costs compared to conventional desalination where the energy costs can represent up to 60% of operation costs.

Zero land space

Oneka’s freshwater technology does not require obtaining land-based real estate, which is required for land-based solutions, particularly when compared to solar-powered desalination. Oneka simply connects the fresh water pipe to the water distribution network or to a water storage tank. We believe that preserving coastal land is of high importance. By limiting land usage, our system significantly reduces the impact on deforestation, as compared to traditional and solar energy driven desalination solutions.

Eco-friendly brine

Brine is the concentrated seawater returned to the ocean when pure water is extracted from seawater. The Oneka brine has a salinity that is only slightly higher (± 30%) than that of the ocean. Since each buoy has its own water intake and outlet, the brine is discharged over a broad area and quickly diluted. Thus, it has a minimal impact on the salinity of the ocean, which limits the degradation of the marine ecosystem.

Scalable & modular system

Oneka’s system can easily follow the client’s evolving water needs. There is no need to build a new desalination plant infrastructure or large installations in advance. The volume water produced by Oneka’s system can simply be adjusted by changing the number of units in the buoy array. Any procedure needed to modify the buoy array is done by Oneka and doesn’t require any involvement of the client.

Mostly made from recycled plastics

In addition, the buoys’ structure is mostly made of recycled PET from plastic bottles. An array of 7 Iceberg-class units would represent nearly 1.2 million recycled plastic bottles.

Artificial reefs

Our experience has demonstrated that the concrete anchors used by the Oneka buoys are quickly populated by marine life. The anchors are typically placed on barren sea floors which are naturally converted into artificial reefs in a manner of months.


For our team, it is important to be proactive within the various associations and communities who share our values. We sincerely believe that by sticking together, it is possible to solve the greatest challenges facing humanity.
