RAA to Lead Integrated Urban Drainage Guidance Update

10 September 2019   (0 Comments)

 Hydraulic modelling specialist Richard Allitt Associates (RAA) has been appointed to take the lead on updating the industry standard guidance on integrated urban drainage with AECOM.

The Chartered Institution of Water and Environmental Management (CIWEM) and the Environment Agency have selected RAA and AECOM to update the industry standard guidance on Integrated Urban Drainage.

Together they will work with other technical experts including Maltby Surveys, Bluesky and Onsite to develop the new guidance for CIWEM and the Environment Agency.

The original guide was published by CIWEM’s urban drainage group (UDG) in 2009 with the purpose of informing practitioners on the then emerging technologies for advanced flood modelling in urban areas, notably the use of coupled 1D-2D models and the integration of models representing sewers, watercourses and the urban surface.

In the last decade, technologies and good practice have advanced considerably.

In addition, the introduction of Water UK’s new Drainage and Wastewater Management Plans (DWMPs) require an enhanced level of partnership working to address flood risks of this nature and develop programmes for improved urban resilience.

The project steering group consists of representatives from CIWEM UDG, EA and Lead Local Flood Authorities as key stakeholders.
