What is a benefit of harvesting rainwater?

Harvesting rainwater provides a significant benefit by reducing runoff. This practice allows for the capture and storage of rainwater, which can be utilized for irrigation, flushing toilets, or even potable uses, depending on local regulations and treatment systems. By directing rainwater into storage systems instead of letting it flow over impervious surfaces, the quantity and rate of water entering drainage systems and natural waterways are decreased. This reduction in runoff plays a crucial role in minimizing erosion, lowering the risk of flooding, and improving water quality by preventing pollutants from being washed into streams and rivers.

This approach aligns well with sustainable design practices within the LEED framework, as it contributes to better management of water resources and encourages responsible water usage in buildings and landscapes. Additionally, it can support urban planning efforts by promoting groundwater recharge and reducing the burden on stormwater infrastructure.
