Water scarcity is among the greatest challenges of the 21st
century. Oneka has an extensive mission: making the oceans a
sustainable and affordable source of freshwater.
By using mechanical buoys rather than conventional systems, we avoid emitting
significant amounts of greenhouse gasses. The Oneka system does not require electricity,
fuel or solar panels for the desalination process. Only waves of decent height are required
to produce drinking water.
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.
Oneka’s partners, clients, collaborators are:
Oneka desalination buoys have versatile applications
and can provide fresh water to a variety of entities
located in coastal regions.
By providing you fresh water from our technology, we will:
Give you access to a reliable and economical solution
Provide you with a drought-proof water supply at a fixed cost
Help you achieve your sustainable development goals
Oneka offers an all-in-one desalination system. Everything needed to produce drinking water from seawater is included in the Oneka system. 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.
By using our solution rather than conventional systems powered by gas and electricity, we avoid emitting significant amounts of greenhouse gasses. Compared with conventional systems, Oneka saves 1 tonne of CO2e per year for every m3 of water produced every day.
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.
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.
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.
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.
The intake system is designed to protect marine life. 60-micron inlet holes prevent damage to ecosystems. Backwash reduces maintenance and protects mesh.
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.
