Case Study

Imagine H2O powered SENTRY’s growing impact—from development to pilot to scale


Imagine H2O Accelerator 2018, Urban Water Challenge III

Focus Area

Wastewater Treatment

SENTRY spent four years developing their wastewater treatment product without any significant marketing or outreach to the water industry. In 2018, SENTRY’s participation in the Imagine H2O Accelerator gave them powerful new tools to identify and understand potential customers, new applications, and market opportunities. This was the single biggest catalyst in launching their product to a global audience.

In early 2020, SENTRY secured their first contract with Singapore PUB. They wanted to leverage this project as a key reference for exploring other opportunities in the Asia-Pacific. Imagine H2O Asia advised SENTRY on market entry, showcased the solution to its regional customer network, and ultimately helped secure new pilots with partners in Malaysia, Vietnam, and China.  

As they continued their global expansion, SENTRY applied to the Urban Water Challenge to jumpstart a deployment in South America in partnership with leading water consultants and the World Bank. With this project, their platform assessed the resilience of existing wastewater treatment facilities that service 21M people. 

This milestone brings them one step closer to being recognized as the industry standard—and making sure that no wastewater goes untreated.

Imagine H2O makes water innovation possible. They sort through the best of the best and provide truly valuable solutions to the water sector.

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.
