Community engagement – a case study from Portland, Oregon, USA, by David Schofield, Hydro Consultancy
There are a growing number of exemplary sustainable drainage (SuDS) case studies in the USA, with many of them driven by the need to satisfy the environmental demands of the well-established and Federal implemented Clean Water Act (CWA) 1972.

“Of course the concentrations are high – you sampled during a period of heavy rain” thus I was told off when trying to interpret data from a survey of the Ditton brook near Liverpool in the mid 1970s. No-one talked about diffuse pollution in those days; the awareness that high flow conditions often meant higher [...]
Brian D’Arcy begins a series of Water Reflections with a look back to the 1970s and how old pollution problems may have been solved, then asks – what is standing in the way of tackling the remaining problems surrounding surface water management?
Urban Water Journal, Volume 7, Issue 6, 2010 Abstract The effects of various design configurations and the operation of detention basins for pollutant removal efficiency is evaluated using a Monte-Carlo simulation approach. A physically based numerical model representing the build-up and wash-off of pollutants from the highway surface has been used to predict storm events [...]
Urban Water Journal, Volume 7, Issue 6, 2010 Abstract The planning and implementation of sustainable urban drainage systems (SUDS) requires intensive collaboration between professions and institutions. To improve the conditions for such practice in Denmark, the first loop of a SUDS-based retrofitting project was completed in Odense over a 6-month period. The project involved officials [...]
Urban Water Journal, Volume 6, Issue 5, 2009 Abstract Recent studies on climate change indicate a growing frequency and intensity of flash flood events in western Europe. Flash floods are caused by extreme local precipitation. The URBAS project is concentrating on the urban occurrence of flash floods in Germany. URBAS has as a main objective [...]
Urban Water Journal, Volume 6, Issue 4, 2009 Abstract Norway has frequently encountered flood damage in urban areas during recent years. In this paper the authors, taking Veumdalen catchment in Fredrikstad as an example, simulated the possible consequences in the sewer system, in the present, predicted and artificial climate scenarios. Indicators that describe (1) surface [...]
Urban Water Journal, Volume 5, Issue 3, 2008 Abstract Disaster management for urban areas is a growing priority owing to factors such as the relentless migration to cities, unplanned development, changing climate, and increasing operational and maintenance costs. New information and communication technologies offer improved opportunities to address these factors. This paper presents and describes [...]

The Institute of Civil Engineers published its report in May 2011. It assesses the likely impacts the Flood and Water Management Act (2010) (England and Wales) will have on the authorities responsible for the preparation for, protection against and response to flooding events, including clarification of responsibilities, promotion of data sharing and partnerships, availability of [...]
Paper by R. Y. G. Andoh (Hydro International plc) and C. Declerck (La Missonnais) presented at the 8th International Conference on Urban Storm Drainage, Sydney, Australia (30 August – 3 September 1999) The paper describes the results of a study investigating the cost and operational benefits of source control and distributed storage. Hypothetical catchments based [...]
This DTI Global Watch Mission to the US is regarded as a significant milestone in SUDS development and helped to form SUDS thinking. Co-ordinated by British Water, the mission of UK industry representatives examined storm water management best practices in the US and their implications for the UK.
The benefits of Green Roofs are well documented and established, but uncertainty remains as to whether they can provide attenuation and storage for storm water. Micro Drainage worked with the University of Sheffield to pragmatically model the runoff from a green roof.
A novel integrated system providing ‘hard’ or engineered solutions to SUDS, Source Control and Rainwater re-use is described.
