In Merri-bek we have regional and local drainage catchments. Melbourne Water manages the (larger) regional catchments and Council manages the (smaller) local catchments. In the regional catchments:

  • Stormwater comes from the local catchments and flows into rivers and creeks.
  • Melbourne Water has regional (main) drainage infrastructure. 
  • Mapping for the regional stormwater flow paths has been included in the Merri-bek Planning Scheme and is shown by the Special Building Overlay, Schedule 1 (SBO1). These maps are on the Victorian Government's Planning website.
