Runoff Reduction:
interception
storage
evapotranspiration
infiltration
Flood Risk Management:
reduced floodplain
mitigation
Water Reuse
Water Treatment:
sedimentation
bioretention
Benefits:
less water to treat
less pressure on water supply
groundwater recharge
less flood damages
potential increase in house price
cleaner runoff
