About the SIA


The rate of Stormwater evolution has increased over the past few decades.  In the first half of last century, stormwater was only about flooding prevention however in the second half of the 20th century, the focus gradually shifted to water quality and pollution control.  With the Sydney Olympics coming to town in 2000, the NSW government allocated $80M for the purpose of improving stormwater and this gave a real boost to the underfunded stormwater industry.


Since the Olympics, Councils have continued to implement their Stormwater Management Plans.  They can now raise money from the Stormwater Management Service Charge and the range of treatment options has expanded greatly.
Of recent times, the industry focus has been just as much on source control and Water Sensitive Urban Design, as it has been on more traditional gross pollutant traps and concrete conveyance options.


The current focus of most Council’s who own and operate stormwater systems is to increase their level of sustainability, by installing stormwater harvesting solutions for non-potable reuse of treated stormwater.


The Stormwater Industry is relatively young, especially in Australia, and our rate of evolution has been incredible over the last two decades.  Part of this evolution is due to the dissemination of information by Stormwater NSW.   The thanks for this goes straight to our members who have provided information, attended our seminars and contributed to the development of our industry.


Stormwater NSW has many public stakeholders:

  • State Government departments dealing with Environment, Planning, Construction, Education, Water and Sustainability
  • Local Government who own the majority of the stormwater and manage it as best they can within multiple constraints that include budgetary ones

The Federal Government that recently showed its support for stormwater harvesting with $200M in grants

Our members come from a wide range of occupations and include:

  • Consulting and Engineering practices
  • Surveyors and Urban Planners
  • Architects and Builders
  • Civil Construction Contractors
  • Universities and research institutions
  • Manufacturers of stormwater products & equipment
  • Service industries to the environment and water quality industry such as maintenance contractors

Stormwater NSW continues to grow and we welcomes inquiries from new individual and corporate members who wish to make a positive contribution to the peak industry body for stormwater professionals in NSW.


From a professional development perspective, the Association aims to provide several seminars each year, as well as our annual conference.  We also aim to become a resource for stormwater professionals and a source of information for wider community including schools, industry  and the media alike.


Stormwater NSW is run by a voluntary committee that are all passionate about improving the management of stormwater.
