Robin is a founding 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 Civil 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.
