What is a common strategy to reduce potable water use in buildings?

Using greywater recycling systems is a common strategy to reduce potable water use in buildings because it allows for the reuse of water from sources such as sinks, showers, and washing machines for non-potable applications. This approach can significantly decrease the demand for fresh, potable water by redirecting greywater for irrigation, toilet flushing, or cooling systems, thus enhancing water efficiency.

Implementing greywater systems contributes to sustainable water management practices by reducing the strain on municipal water supplies and wastewater systems, leading to more environmentally responsible water usage in buildings. Additionally, this method can help projects earn credits under the LEED Water Efficiency category, promoting more sustainable building practices.
