3.0 Water Quality Management
3.1     Background
A requirement of the proposed development is that Stormwater quality treatment shall be provided to meet
the design objectives set out in Section 2.4 of DERM’s Urban Stormwater Quality Planning guidelines 2010
and the associated with State Planning Policy (SPP) 4/10 Healthy Waters. 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

        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
