Transformative integrated solutions
towards better reservoirs.

Team

At CHATTIGR, our strength lies in the synergy between visionary leadership and scientific rigor. Founded in Norway in 2023 and fueled by an intensive industry-academia partnership with the University of Bergen, we are a professional team dedicated to a mission-driven goal: ensuring the sustainability of global water and energy infrastructure.

We recognize that by 2050, the world risks losing roughly a quarter of its reservoir storage—a vital buffer for drinking water, irrigation, flood control, and carbon-free energy. Our team is committed to making innovative sediment management both accessible and useful. We don't just engineer systems; we protect livelihoods, preserve ecosystems, and lead with a core commitment to integrity, transparency, and environmental stewardship.
