9.4.8             Water Quality and Drainage Code

9.4.8.1           Application

   (1) This code applies to assessable development identified as requiring assessment against the Water Quality and Drainage Code by
       the tables of assessment in Part 5 (Tables of assessment).
   (2) All provisions in this code are assessment benchmarks for applicable assessable development.

9.4.8.2           Purpose and Overall Outcomes

   (1)   The purpose of the Water Quality and Drainage code is to ensure development is planned, designed, constructed and operated
         to manage wastewater, stormwater, groundwater and environmental flows and as part of an integrated water cycle in ways that
         protect environmental values, water quality and public health.
   (2)   The overall outcomes sought for the Water quality and drainage code are:
         (a)   Waterways, wetlands, drainage lines, receiving environments and other ecologically important areas are protected and
               enhanced by managing the quality and quantity of stormwater runoff from development in accordance with best practice;
         (b)   Stormwater drainage systems are designed and constructed to effectively manage or convey stormwater in a way that
               protects people, property and the natural environment;
         (c)   Stormwater infrastructure and treatment systems are compatible with existing infrastructure and are designed and
               constructed to be cost effective across their design life;
         (d)   Stormwater design and management incorporates consideration of climate change impacts to ensure the intended function
               and capacity of the stormwater infrastructure and treatment systems are maintained over time;
         (e)   Stormwater infrastructure provides an appropriate level of flood immunity for roads based on desired standards of service
               identified for different flood hazard areas;
