THE HYDROLOGIC CYCLE 99% inaccessible (saltwater/ice) 1% precipitation, runoff,

Current US average residential water use

With water recycling – 25% reduction

With water recycling and on site treatment – 40% reduction

WATER CATCHMENT Simple technique Reduces consumption for potable water Deduces storm water runoff and subsequent flooding Lowers cost of water supply ELEMENTS: Catchment, conveyance, purification, storage, distribution

WATER REUSE AND RECYCLING using water more than once in a building Water Recycling: reutilization for same application Water Reuse: reutilization for different application (for example a graywater system)

POTABLE WATER Usually treated, for drinking RAINWATER GRAYWATER SYSTEM: Wastewater NOT containing food and human waste BLACKWATER SYSTEM: Wastewater containing food and human waste Architectural Issues: Water Reuse can be celebrated and used as a learning tool (expose storage and treatment systems)
