The 
          maintenance of a reedbed does not require specialized labor or many 
          controls, but it is recommended a minimum management through a few simple 
          steps outlined below.
         
          
            - Septic 
              tank and grease trap control. It is essential for the proper 
              functioning of the wetland to periodically purge the septic tank 
              and the grease trap.
              Frequency: 1-2 years (depending on their capacity) 
          
          
            - Weed 
              control. Especially in the starting phase of the reedbed 
              is possible that weeds take root on the gravel area thereby inhibiting 
              the growth of aquatic plants: in this case it is sufficient to eradicate 
              the weeds.
              Frequency: 3 months in the starting phase, 6 months in the operating 
              phase
