Water Quality Testing
Regular water quality testing of the WQCP (other than testing for mosquitoes and cyanobacterial blooms, as specified
below) is not proposed. Visual performance indicators are to be assessed as presented in Constructed WQCP Inspection
Checklist in Appendix A.
Any water quality testing undertaken would be part of a catchment wide testing program, by others, or unless a specific
site issue has identified the need by an inspector.
If Water quality testing is requested it may involve a chemical analysis of the WQCP or a macro‐invertebrate analysis of
the WQCP or downstream waterways. The chemical analysis of the WQCP should be undertaken in accordance with the
relevant Australian standard and samples should be taken at the inflow and outflow points of the constructed WQCP.
For the macro‐invertebrate analysis various documents are available which outline the methodology required to
undertake the assessment. The following publications provide some guidelines to macro‐invertebrate analysis:
   SIGNAL 2. – A Scoring System for Macro‐invertebrate (‘Water Bugs’) in Australian Rivers, Monitoring River Health
    Initiative Technical Report No. 31 (Chessman 2003).
   Australia Wide Assessment of River Health Australian Capital Territory Bio Assessment Report (ACT Interim Final
    Report), Monitoring River Health Initiative Technical Report No. 3 (Keen 2001).
   Australian River Assessment System: National Guidelines for Mapping AusRivAS Aquatic Macroinvertebrate Score.
    Monitoring River Health Initiative Report No. 38 (Gray 2004).
Yearly Review of Maintenance Management Plan
Each year a review is to be carried out to determine if the programmed inspection and maintenance (including checklists)
is ensuring all SQIDs are functioning as intended. The review should include an assessment of the maintenance
database to determine whether the programmed inspections and maintenance is effective. Information on the database
should be assessed to determine whether any noticeable changes are evident in vegetation, presence of fauna and
operational efficiency of any structures or features of the device. This will further provide indicators as to whether
sufficient information is being recorded for management purposes.
Annual review of performance indicators (e.g. macrophyte coverage and dieback rate and upper concentration limits for
Microcystis aeruginosa or biovolume equivalent) are to be assessed against latest peer reviewed journal publications and
health regulations to ensure performance targets are still appropriate. Updates to performance indicators are to be made
if required.
Maintenance Personnel Safety (OH&S)
The QLD Work Health and Safety Act 2011 requires that all reasonably practicable steps be taken to protect an
employee’s health in a workplace. Organisations involved in the inspection and maintenance of the SQIDs should
therefore ensure the follow.
   Have a documented occupational health and safety policy in place;
   Ensure all staff and maintenance personnel are aware of and abide by the policy; and
   The policy provides a mechanism for review and improvement.
As part of the policy personnel involved in the maintenance of the SQIDs are to have sufficient resources (such as
personnel protective equipment, training etc.) to carry out the task in a safe manner.
General Public Safety
The safety of the general public in the area of SQID maintenance operations shall be ensured. Depending on the nature
of the operations, the following may be appropriate;
   Notices to inform the public of SQID maintenance may be circulated prior to the scheduled date.
   Temporary signage and safety barriers may be erected around maintenance work areas prior to the works
    commencing and are not to be removed until all works have finished.
   Signage is to be erected around the WQCP system should toxic algal blooms be recorded at levels that trigger the
    “Red Level Action Mode” as specified in Table 7.2.1 of the Queensland Water Quality Guidelines 2009. An extract is
    provided in Appendix A. Appropriate corrective measures are to be undertaken during this event.
Where maintenance works are to be conducted on roads, traffic control should be included.
