Attenuation Tanks


Attenuation tanks are vital components of modern water management systems, designed to mitigate the impact of heavy rainfall and reduce the risk of flooding in urban and suburban areas.

These underground reservoirs temporarily store excess stormwater, allowing it to be released slowly into drainage systems or natural watercourses at a controlled rate. By preventing sudden surges of water, attenuation tanks help protect infrastructure, prevent erosion, and minimise the risk of pollution in rivers and streams.

Benefits of SuDS

We are all aware of the problems caused by increasingly frequent and exceptionally heavy rain. The situation has been made worse by the loss of permeable landscape, and its replacement by hard landscaping, paved areas and vast areas of tarmac. Even our low maintenance, patio-focused gardens contribute to the problem. Our traditional piped drainage system can no longer cope with increasing amounts of surface run-off - rainwater with nowhere to go. The result is serious flooding, pollution, damage to property and animal habitats, and contamination of groundwater sources.

Sustainable Drainage Systems, or SuDS, are a natural and effective approach to managing drainage in and around properties and other developments. They mimic 'natural' drainage by adopting techniques which slow water which runs off from a site.

Our self-contained systems store water and slowly release half of it into the local drainage network. Easy to install as a retrofit or to a new build, they slow peak flows and alleviate flood risks whilst making our gardens greener.

SuDS stands for Sustainable Drainage Systems.

SuDS use a combination of features such as permeable paving, swales, rain gardens, detention basins, and ponds to collect, store, filter, and gradually release rainwater into the environment.

Sustainable Drainage Systems (SuDS) are designed to manage surface water runoff from rainfall in a way that mimics natural drainage processes. They help reduce flood risk, improve water quality, and enhance the local environment.

A SuDS pond (Sustainable Drainage System pond) is an eco-friendly water management feature designed to capture and slowly release rainwater

Yes, but generally straightforward. Regular inspections, vegetation management, debris removal, and occasional sediment clearance help ensure SuDS continue to perform effectively.
