Abstract / Summary:

Stormwater Flow and Quality and the Effectivenemss of Non-proprietary Stormwater Treatment Measures - A Review and Gap Analysis

Preface

There is an increasing emphasis, both in Australia and overseas, on the need to manage urban stormwater in a way that minimises the impact on receiving waters. With this increased attention, has come a rapid development in knowledge of key issues affecting stormwater management:

i. The impact of urbanisation on hydrology.
ii. Expected stormwater quality emanating from catchments of different land uses.
iii. The performance of a range of stormwater treatment measures in reducing stormwater pollution.
iv. Maintenance and operation of stormwater treatment measures.
v. Expected lifecycle costs of stormwater treatment measures.

This knowledge has been developed by a wide range of researchers and industry practitioners. Consequently, it is difficult for any one organisation to use this information effectively. In addition, despite the recent advances, there are still many knowledge gaps which impact upon the ability of stormwater managers to prioritise, optimise and evaluate their strategies. NSW Environmental Protection Authority (through their Stormwater Trust) therefore commissioned this report, to synthesise existing data across the five identified themes (listed above), and to identify and prioritise gaps, in order to direct their own future research activities. The data compiled in this report, whilst having a NSW focus in some sections, is of value to stormwater management agencies throughout Australia. However, whilst providing a valuable
reference document, readers are urged to supplement the information provided with locally-specific data wherever possible.

Perversely, I hope that this report becomes out of date relatively quickly, as a result of significant further advances in our understanding of stormwater hydrology, quality, treatment, impacts and management.
