UV water disinfection is a highly effective, efficient, environmentally friendly, and sustainable grey water solution. It uses ultraviolet light to eliminate harmful bacteria and viruses without adding chemicals, so the water is safe for non-potable (non-drinkable) uses.

Why does the water need to be safe for non-potable reuse? Preserving the water quality without altering its chemistry makes it suitable for purposes such as irrigation or toilet flushing without causing harm to plants, soil, or plumbing systems.
