Sustainable Drainage Systems (SuDS) in Yorkshire, online

Watch this event

Landscape architects 2B Landscape Consultancy Ltd have extensive experience spanning over 30 years in Landscape Design, Assessment and Visualisation, with a special interest in Sustainable Drainage Systems (SuDS).

SuDS design teams will be familiar with the four pillars of SuDS; quantity, quality, amenity and biodiversity, but often find their clients asking – “but isn’t it going to cost more?”

When 2B was asked to provide a planting plan for an already designed drainage system, they worked with the quantity surveyor to demonstrate that a landscape-based SuDS scheme would have saved 1.5% on the construction budget, had landscape architects been involved in time.

Join us for this knowledge sharing event to find out how early engagement with landscape architects on drainage design can reduce scheme costs and deliver on the four pillars of SuDS. 

The webinar will explore how reducing costs can be achieved alongside the four pillars of SuDS by:

  • Reducing the need for underground tanks and pipework. 
  • Using site earthworks to construct the landscaped SuDS.
  • Avoiding costs associated with connections by using natural drainage pathways.

Following a recap on good SuDS principles generally, 2B will walk through the proposed landscaped SuDS Design for the University of Hull student accommodation case study, including the detail of where cost savings were identified compared to conventional drainage design. 

Yorkshire Water will provide a brief overview of the 2020 Sewerage Sector Guidance as it relates to adoptable SuDS, and detail the types of landscaped SuDS that can be presented for adoption locally.
