Level Wetlands (LW) are a new type of wetlands that are optimized for re-circulation of nutrients as opposed to earlier focus which have been on the resource-wasteful process of denitrification. By being able to control the water level, recovery of nutrients by removing sediment and putting them back on the fields is facilitated. The efficiency is expected to be high when permanently low water levels optimize sedimentation and where flow peaks can be infiltrated in specially designed infiltration banks. In these infiltration banks the nutrients will be accumulated in tree biomass.
