Insufficient management of stormwater can result in overwhelmed sewer systems, erosion, and the degradation of natural water bodies. As rainwater flows through urban areas, it accumulates pollutants from roads, rooftops, and other surfaces and is collected and diverted by what is commonly referred to as 'grey infrastructure’. But these systems are designed to handle historical rainfall patterns and are overwhelmed by erratic and unprecedented rainfall events seen more often in recent years. And when the excessive runoff is discharged from overloaded sewer systems into streams or rivers, it not only pollutes these delicate ecosystems but also causes damage due to flooding.
