Dr Robin Allison, Director, DesignFlow

Robin is a foRobin Allisonunding Director of DesignFlow, a specialist water sensitive urban design consultancy based in in SA, Victoria and Queensland.

He has more than 20 years’ experience in stormwater management and in particular integrating WSUD into urban spaces to protect aquatic ecosystems while enhancing people’s enjoyment and appreciation of water.

He has delivered projects from streetscape scale to regional wetlands and a focus is often on retrofitting systems within constraints of existing urban areas.  All of the systems employed use vegetation as a key driver of water quality improvement and promote green infrastructure.

Ralph Williams, Senior Engineer, DesignFlow

Ralph is a CRalph Williamsivil Engineer with a Masters in Hydrology and Water Resources and has 20 years’ experience in Australia and overseas.  He has a particular interest in water treatment, recycling and aquifer storage and recovery.

His practical skills in design and construction supervision compliment his conceptual design and modelling approach ensuring that strategies and plans are practical and can be easily implemented.

Applying his highly technical design skills to help develop community orientated outcomes as part of broader water sensitive urban design objectives is a major focus for Ralph.

Andrew King, Coordinator Engineering Services, City of West Torrens

Andrew King - Head ShotAndrew is a Civil Engineer with experience in all levels of Government and private practice, currently employed as a senior engineer with the City of West Torrens. He considers himself lucky to have been mentored and influenced by some of South Australia’s most respected and passionate water professional and academics.

As long standing Chair of Stormwater SA and a member of many of the stormwater reference committees, working groups and networks established over the past decade, Andrew is consistently pushing for better practices, capacity building, guidelines and legislation in relation to stormwater management, Water Sensitive Urban Design (WSUD) and related fields.

Andrew has been involved in the development of a cultural change within the City of West Torrens, to the point where this council is thought to be the most progressive inner urban council in South Australia with regards to the adoption WSUD measures.  The change of daily practices in the management of the cities infrastructure has seen the city now heading towards the installation of 200 individual ‘Rain Gardens’ and the adoption of best practice WSUD into a substantial number of private developments through influence in the development process.
