3.0 Water Quality Management

3.1     Background
This section of the report will outline the measures to be adopted to control the quality of stormwater
which leaves the site.        The scope typically encompasses the ‘post construction’ phase of the
development however ‘construction phase’ water quality is briefly addressed.


3.2     Construction Phase
Table 3.1 has been adapted from Table C4.1 of Brisbane City Council’s (BCC) Stormwater Best
Management Practices 2000 and details the typical stormwater pollutants which may be generated
during the construction phase of the development.

                  Pollutant                                       Sources

                     Litter                    Paper, construction packaging, food packaging,
                                                          cement bags and off-cuts

                  Sediment                     Unprotected exposed soils and stockpiles during
                                                          earthworks and building

               Hydrocarbons                Fuel and oil spills, leaks from construction equipment

               Toxic Materials            Cement slurry, solvents, cleaning agents, wash waters

          pH Altering Substances                        Cement slurry, wash waters



                                Table 3.1 –Typical Construction Phase Pollutants

        The following measures should typically be implemented prior to the commencement of
        construction:

                 Education of all site workers in sediment and erosion procedures

                 Specified storage areas for construction materials and plant that are bunded to prevent
                 any spillages from escaping

During the construction phase of the development, silt fences should be erected downstream of all
disturbed areas. In addition erosion and sediment control devices should be regularly inspected and
maintained following storm events. An Erosion and Sediment Control Plan will be provided as part of
the operational works application process.
