Water treatment tech

Helpful bacteria are turning agricultural and oil-and-gas wastewater into clean water and energy, acoustic methods are shaking contaminants out, and engineered viruses are keeping harmful bacteria in check. The long-term future? Water treatment that's compact, mobile and off the grid.

New water cycle

Why waste our water? Engineers envision a new cycle of water reuse, an urgent need where water is scarce. That means using greywater right where we make it, capturing stormwater and run-off, and understanding how contamination affects our waterways and homes.



Engineering clean water

Engineering researchers are creating new ways to handle drought, chemical spills and water purification. Imagine a clean water future.
