The idea
Bath, basin and laundry water - greywater - is the easiest water to reclaim. Simple treatment makes it perfect for flushing and gardening, halving your freshwater demand.
What to know
Systems range from simple filter-and-reuse setups for gardens to compact treatment units feeding flush lines. Best planned during construction or renovation when dual plumbing is easy; retrofits work where bathrooms cluster on one side of the house.
