5.5        WSUD Implementation
Experience shows that the critical periods in the life of WSUD vegetated stormwater systems are
the construction and establishment phases. The timing and approach to these systems must be
carefully considered to ensure successful establishment and long-term performance.
Bioretention systems are common stormwater treatment devices for new urban developments in
South East Queensland. Successful construction and allowing adequate time for the systems to
establish is critical to their long-term performance and function. Construction of the system is
also linked to having suitable bioretention designs in place to ensure civil contractors have
appropriate plans to construct to. Applying due care in the design and construction phase will
ensure the function of the system whilst also keeping on-going maintenance to a minimum. It is
highly recommended that the following guidelines are followed through the design, construction,
establishment and maintenance phases.

5.6        Maintenance and Operation
Maintenance for the bioretention basins may involve the following:


      1.   Scheduled inspections;
      2.   Removal of noxious plants or weeds;
      3.   Maintaining the desired vegetation;
      4.   Repairing erosion;
      5.   Unblocking inlets and outlets;
      6.   Removing litter and debris;
      7.   Managing algal or moss growth;
      8.   Maintaining the permeability of
