Attenuation Storage


Before you embark on a construction project, you need to put a concrete plan in place to handle surface water and runoff water. Part of this will be pinpointing the size of attenuation storage tanks that will be required for your development and drawing up flow attenuation proposals in line with your business needs and legislation.

Attenuation storage will be needed to hold back this water to achieve a more manageable runoff rate during a flooding event, which it will then release slowly once retained.
Express Drainage Solutions are an expert consultancy and one-stop drainage specialist who will assess your individual plans to create a strategy for how to attenuate surface water and advise what equipment and tanks will be needed, thanks to our accurate estimation of attenuation storage volumes for a site. As part of our services, we can suggest ways of reducing water flows in the event of stormwater events or increased runoff, and examine how best to manage the situation.

We will also complete any works or installation, making us the go-to professionals for a start-to-finish job. For full drainage services and surface water management plans, please get in touch with our experts. We cater for businesses and projects across London and beyond, offering comprehensive solutions to suit your individual needs.
