our vision is to
elevate water

What drives us

Water is scarce and sources are shrinking as use continues to rise. Something needs to be done… and we’re on it.


Our technologies and chemical solutions make industrial water usage sustainable. We’re engineering a greater balance between mankind and the planet. Our goal is to ensure water for all of society — both now and into the future.

45%

of the world’s water is used by Industry

70%

of wastewater is dumped untreated into nature

Sustainability is at the core of the work we do at Gradiant. We help our customers minimize their water footprint by reducing water consumption, reclaiming valuable resources, and renewing wastewater so it can be returned to nature.


Our technologies enable industries to be sustainable in their operations and supply chains. Much more than regulatory compliance — increasingly customers, employees, and investors are driving the need for a sustainable supply chain. It’s a win-win — the right thing to do and good for business.
