Assessment of Risk and Inspection Frequency

All properties with existing OSSM systems within AlburyCity LGA will receive a risk assessment rating evaluation to identify site features and constraints. Properties will be allocated a risk level of either high, medium, or low depending on the potential public health or environmental risks. The main considerations in determining risk include:

  • Location and size of the land
  • Drinking water catchment areas
  • Groundwater bores on-site or nearby
  • Permanent and intermittent surface waterways and stormwater drainage channels
  • Effluent land application method
  • Commercial and public businesses
  • System design, condition and observed performance
  • The amount of wastewater generated
  • Soil type
  • Vegetation coverage
  • Slope of the land
  • Distance to watercourses, drains and property boundaries
  • Surface or subsurface discharge of effluent, and
  • Risk of flooding

Based on site features and constraints, a risk rating will be issued for your system and will determine inspection frequency and approval to operate period.
