With the bulk of population growth in Australia generally occurring in the capital cities and major regional centres, there is continually increasing demand on drainage infrastructure. Increased dwelling density in established suburbs, as well as the need to upgrade transport and freight links through urban areas, can produce significant challenges in developing drainage solutions that are both equitable for existing residents as well as providing for the future needs of the broader community. This can be true even for greenfield development on urban fringes, where sustainable and ecologically beneficial drainage strategies are required. WMAwater is experienced at overcoming these challenges and providing comprehensive strategies for urban drainage that satisfy a wide range of stakeholder interests.

WMAwater offers a range of services related to urban drainage assessment and design, including:

  • evaluation of existing stormwater drainage systems
  • development of drainage strategies and concept designs
  • impact assessments for new development
  • preparation of detailed management plans – prioritisation of works to address black spots and budgetary constraints
  • establishing stormwater critieria for development control plans (DCPs) in urban renewal precincts
  • section 94 plan preparation and contributions assessment
  • on-site detention systems analysis and design

Specific Projects

  • Marrickville Flood Study: A Flood Study constitutes the first stage of the NSW floodplain risk management process. WMAwater completed a Flood Study for the areas including and adjacent to Marrickville (including parts of or all of the suburbs of Petersham, Stanmore, Enmore, Newtown, St Peters, Tempe, Marrickville and Dulwich Hill). The study was prepared for Marrickville Council under the guidance of NSW Government staff and Council’s Floodplain Risk Management Committee (FMC). The study involves the development of models and the quantification of the existing flood risk, and provides the basis for the future management of flood liable lands within the study area.
  • Perth Airport Master Drainage Strategy: Perth Airport covers an area of approximately 2,100 hectares and since 1997 has been operated by Perth Airports Pty Ltd, who are undertaking substantial redevelopment of the airport estate. The planning framework for future development as outlined in the Perth Airport Master Plan includes an additional runway, new aprons, taxiways, terminal upgrades, improved road access, and significant commercial development outside of core airport-related activities.
