SuDS (Sustainable Drainage Systems) and NFM (Natural Flood Management) are excellent surface water management techniques to help alleviate flooding, improve water quality and complement water security at the same time as enhancing the public realm.
Our approach to sustainable drainage combines traditional civil and infrastructure engineering with landscape-led approaches to deliver source control solutions in line with an integrated water management philosophy. In addition to the core aim of managing surface water on the surface within a treatment train, our solutions look to improve biodiversity while reducing urban heat island effects, the carbon footprint, and potable water demand – all essential in addressing the current climate and ecological crisis whilst achieving sustainable development that doesn’t compromise the ability of future generations to meet their own needs.
As co-authors of the CIRIA SuDS Manual, SuDS design is in our DNA. Our experts have years of experience and contributed to the development of current guidance relating to sustainable drainage.
As members of SusDrain we prioritise being part of the ongoing dialogue on sustainable drainage, providing the best-practice dissemination and training in these disciplines.
Our excellent track record in the delivery of exemplary and innovative designs speaks for itself, and we regularly support ongoing projects when specialist SuDS design is required. EPG delivers certified CIRIA SuDS training.

An integrated approach – the benefits
Sustainable drainage and natural flood management have multiple benefits beyond effectively managing surface water runoff. By replicating natural drainage processes, surface water is more effectively managed. In addition to providing drainage solutions, SuDS and NFM provide multiple other benefits including improved water quality, biodiversity and amenity value. By working to the four pillars of SuDS, we ensure that we maximise the benefits delivered through each and every design.
Can this approach be cost effective?
Yes. Whilst the far-reaching benefits of SuDS can be difficult to calculate, such as improvements in health and wellbeing, education opportunities, increasing physical activity and protecting and enhancing habitats, the capital cost is often less than traditional drainage methods.
