A rainwater collection system can significantly reduce or completely eliminate the use of potable
water for irrigation by collecting and storing rainwater for this purpose.
Reference: The LEED v4.1 O+M rating system encourages the use of alternative water sources, like
collected rainwater, to reduce potable water consumption for irrigation, aligning with the goal of
water efficiency in sustainable site management1234.
A rainwater collection system can significantly reduce or completely eliminate the amount of potable
water used for irrigation. By collecting and storing rainwater, it provides a sustainable source of
water for landscape irrigation, thereby reducing the dependency on potable water sources for this
purpose.
