Sustaining a global pipeline of promising water startups
  • We identify the world’s best water entrepreneurs and help them level up.
Building solutions as collaborative partners
  • We equip our entrepreneurs with mentorship, market access and pilot funding.
Developing a stronger, more connected water sector
  • We create trusted investor and customer networks to accelerate the adoption of new technology.

Pilot Support

We deploy pilot funding to de-risk and accelerate the adoption of innovative water solutions.

Barriers to adopt new technologies are high due to risk aversion and financial constraints.

We provide catalytic capital and technical support to overcome these challenges and jumpstart innovation projects.

Deploying pilot funding alongside our startup accelerator programs
Our startup accelerators build a pipeline of pilot-ready solutions and support entrepreneurs through the pilot design process.

Monitoring our impact on water-stressed communities
17 pilot projects were co-funded globally in 2023. Learn more about our latest projects here.

Expanding our pilot support work in 2024
We will be launching the Water Innovation Pilot Fund in Q2. Fund supporters include Oceankind and The Coca-Cola Foundation.

Case Study

Imagine H2O partnered with SmartTerra throughout its startup journey – supporting it from product development to market expansion


Urban Water Challenge I, Imagine H2O Asia 2

Focus Area

Water Efficiency

From prototype to pilot
In 2018, SmartTerra received funding from IH2O’s Urban Water Challenge to pilot an early prototype of their AI-enabled non-revenue water reduction solution. Armed with a successful reference case, SmartTerra was able to iterate on their solution while unlocking new opportunities in other Indian cities. 

Expanding outside of India
After gaining traction in their home market, SmartTerra joined IH2O Asia to identify a landing pad in the wider region resulting in their first pilot in the Philippines. Through a IH2O Asia-World Bank partnership, SmartTerra received on-the-ground support to validate their solution with two small public utilities in the country.

Scaling across the region
IH2O and SmartTerra incorporated the technical and operational learnings from that trial to secure paid pilots with new utilities in the Philippines. With the launch of IH2O’s partnership with The Coca-Cola Foundation in 2023, SmartTerra is now also conducting a multi-city deployment in Indonesia.

Imagine H2O makes water innovation possible. They sort through the best of the best and provide truly valuable solutions to the water sector.
Megan Glover CEO & Co-Founder, 120Water
Innovation is critical to meeting our immediate water challenges, and will become more important with the inevitable curveball of climate change. Imagine H2O is a leading convenor and voice, effectively elevating solutions that create a resilient water future.
Felicia Marcus Former Chair, California State Water Resources Control Board
It’s easy to talk about how hard technology development for water and wastewater applications can be; few voices ever offer real solutions or optimism about facing those challenges. The Imagine H2O community combines the passion for our shared environmental mission with actionable insight about building businesses that drive impact.
Alex Rappaport CEO & Co-Founder, ZwitterCo
Innovation in water is vital but challenging. Imagine H2O gets it right in convening the best and the brightest entrepreneurs alongside innovative tech adopters, influencers, and the right sources of capital in a productive, engaging and fun space. That is what’s needed to move our sector forward.
Ifetayo Venner Wastewater Treatment Service Line Leader, Arcadis
Imagine H2O consistently uncovers and nurtures technologies and leadership teams that will drive the industry forward. I have been truly honored to be a part of Imagine H2O for more than ten years. It is exciting—and deeply gratifying—to work with top innovators in the water sector and with such an impressive group of judges, who bring their wide range of technical and business knowledge to our common goal of transforming the future of water.
