Creating more surface water

Creating surface water

Effects of adaptation measures on water quality
Adaptation measure	Positive effects	Potential negative effects
Adding surface water: Creating additional surface water and storage height Storage pond Greening urban water: Helophyte filter Nature-friendly banks	Fewer sewer overflows Increased purification by helophytes Decrease in air temperature Greater depth (storage pond)	Inflow of bird droppings and dog poo runoff Increase in oxygen consumption (helophyte filter) Increase in soil nutrient content
