Water is a limited resource and is energy-intensive to treat and distribute. Two things to consider:
1. A building’s water needs should fit within the resource limits of its site, meaning it should not use more water than is available (via groundwater or rainwater) on its physical site. Systems like wells or rainwater harvesting can add resiliency, as they don’t rely on a municipal water hookup.
2. Use the right water for the right job; not all building water needs require potable water. Irrigating? Flushing toilets? Think greywater or rainwater.
