Storms are increasing. The demand for effective wastewater processing is continually increasing, and the need to increase network resilience is urgent. When necessary, we have the capability to build.
From small-scale modifications to large-scale tank builds, our created assets are delivered smartly using low-carbon methods such as off-site construction to reduce their environmental impact.
Our nature-based solutions including reed beds and artificial wetlands offer effective biological treatment while enhancing climate change resilience, protecting water quality, and helping clients achieve biodiversity gain and carbon targets.

Storm tank installation
A 55 cubic metre sectional-steel storm tank with sustainable features was installed at a wastewater treatment site to comply with regulations to cut sewage overflows. The works significantly reduced running costs for our client and allowed them to meet specified carbon reduction targets while increasing stormwater capacity to help protect local waterways for decades to come.
