How does green infrastructure benefit wastewater systems?

Green infrastructure plays a vital role in benefiting wastewater systems by managing stormwater at its source. This approach involves implementing natural processes and environmentally friendly designs to control water flow and reduce stormwater runoff. By allowing water to be managed where it falls, green infrastructure enhances the natural hydrological cycle, leading to improved water quality and reduced flooding risk.

This effective management reduces the burden on traditional wastewater systems by minimizing the volume of water that needs to be conveyed, treated, and discharged. Techniques such as rain gardens, permeable pavement, and green roofs enable water to infiltrate the ground rather than overwhelming sewer systems, thus promoting groundwater recharge and improving overall ecosystem health. In contrast, other choices focus on aspects such as increasing flow speed, technological solutions, or reducing soil moisture which do not align with the core principles and benefits of green infrastructure in the context of wastewater management.
