Problem Statements

Pilots and Projects

We understand that pilots and projects are a core interests for companies to achieve market validation. Developing a sizable track record is a known metric which investors and end users look at.

Here at Ripple2wave, we understand the significance of this and work in our best effort to source for pilots and projects. With strong ties to Singapore’s Sembcorp Industries and Public Utilities Board (PUB), we seek to develop opportunities for market validation and everlasting relationships.

Ripple2wave Incubator is on the hunt for innovative solutions to tackle pressing water challenges. If you are a local Singapore startup, we want to hear from you!


Our mission is simple: to provide a platform for groundbreaking ideas and initiatives. With the backing of government agencies and multinational corporations, we're set to launch open challenge calls that could bring pilots and projects to you!

For the upcoming problem statement call that is to be launched in Q4 2023, Ripple2wave

is looking for startups that could solve the following problems:

Greywater Recycling

Greywater recycling is the process of collecting, treating, and reusing wastewater from non-toilet plumbing fixtures in buildings, such as sinks, showers, bathtubs, and laundry machines. The recycling process involves capturing greywater and directing it through a filtration or treatment system to remove impurities and contaminants. After treatment, the recycled greywater can be used for irrigation, toilet flushing, washing cars, or other non-drinking water applications, effectively reducing the demand for fresh, potable water. We are looking for greywater recycling technologies that are low cost, have a low footprint and easy to maintain.

Nitrous Oxide (N2O) Monitoring

N2O, is one of the greenhouse gases that is responsible for global warming.  As compared to CO2, N2O has almost 300 times more impact on global warming. We are looking for holistic systems that can measure the complete N2O footprint for biological treatment process in water treatment plants. The system should not only be accurate, but also cost effective.

Algae Growth and Harvesting

We are looking for technologies that could be used to produce large quantities of algae to produce a pharmaceutical ingredient. This could include technologies that can produce algae by controlled cultivation or technologies that could effectively harvest naturally occurring algae in water using filtration or separation technologies.

Low Energy Desalination

Seawater desalination is the process of removing salt and other impurities from sea water to make it fit for human consumption or other applications. However, seawater desalination is energy intensive, requiring 3.5 kilowatt-hour energy per cubic meter of produced water. This not only makes seawater desalination expensive, but also contributes significantly to global warning due to high carbon emissions. We are looking for technologies that can help to reduce energy consumption to under 2 kilowatt-hour per cubic meter.

If you're passionate about making a real difference in water tech, don't miss this chance to shine! Join us at Ripple2wave Incubator and let's create a brighter, water-secure future together.
