Whether you call it Blue-Green Infrastructure (BGI), Green Stormwater Infrastructure (GSI), Best Management Practices (BMPs), Sponge City, Sustainable Drainage Systems (SuDS), Water Sensitive Urban Design (WSUD), or Nature-Based Solutions (NbS) – we’re talking about clever solutions that work with nature, not against it. These approaches blend traditional engineering with green spaces to create climate-resilient urban environments that manage water whilst delivering multiple benefits

At Q Consulting, we’ve learnt that the best BGI projects happen when everyone’s expertise is on the table early. Urban planners bring the vision, landscape architects craft the spaces, and GIS specialists map it all out. But without solid water engineering, even the most beautiful green space can fail.

Our engineers bring the crucial numbers: storage volumes, control structure designs, flow dynamics, and infiltration rates. It’s about making sure that retention pond isn’t just an attractive water feature – it needs the right storage volume and outlet control to handle that 1-in-100 year return period storm whilst providing amenity during dry weather.

We’ve seen too many projects where different disciplines work in isolation. That’s why we take a hands-on approach – getting everyone talking the same language, whether it’s about hydraulic modelling or planting schemes. It’s not about green versus grey infrastructure; it’s about finding the smart combinations that deliver both performance and sustainability.
