Sustainable and Well-Designed Drainage Strategies

Walsh doesn’t see SUDS as a ā€œbolt onā€ to drainage design. The Walsh ethos is that a well designed drainage strategy should provide sustainable benefits as well as reducing capital and maintenance costs.Ā Ā 

Our designs are influenced by the principle of ā€œMaking Space for Waterā€ and we work with both the Architect and landscape architect to integrate the SUDS seamlessly into the landscape and increase the biodiversity and urban greening factor, thereby providing additional environmental benefits.Ā 

We endeavour to avoid the use of high maintenance underground tanks and promote low maintenance surface level attenuation such as ponds and swales but understand that this is not always feasible and when tanks are required we adopt lean design principles to ensure there is no over provision.Ā 

As one would expect from a practice with innovation as a core value, we are always looking for solutions which add value in a sustainable way and Walsh are also at the forefront of current industry thought leadership. We have sat on CIRIA steering groups providing guidance for blue roofs and take an active role in Thames Waterā€™s Scrutiny Panel.Ā

Taking Sustainability Seriously

Sustainability is in our DNA and we have our own ambitious goals to achieve Net Zero as a business and with our designs. With innovative in-house monitoring tools, Walsh clients have seen on average reductions of 10-20% total embodied carbon, with some of our flagship work achieving 60-70% reductions compared with baseline figures.
