Attenuation Tank with Pumping Chamber

Stormsaver Attenuation tank and pumping chamberAttenuation is a crucial part of any new build in order to provide an effective SUDS strategy.

Our stormwater attenuation tanks are used to collect all roof and surface water on-site, within one vessel. It will be sized to the requirements set out by the consultant in order to attenuate all the rainwater on-site and discharge this to the storm drain, or natural watercourse, at a rate which will not cause downstream flooding.

Once stored inside the attenuation tank, water is released via the pumping chamber. Pumps can be sized to fit your requirements.

Stormsaver offers a range of solutions, but our attenuation tank, combined with pumping chamber is the most standard solution for most sites. However we would always encourage our clients to consider an option that includes rainwater harvesting too; after all, if you are installing a tank to collect the rainwater, you may as well re-use it too!

Quick Quote

“What an absolute credit to our team your engineer was. I was most impressed with the way he worked and couldn’t have asked for a better or more helpful commissioning engineer. I will certainly be recommending Stormsaver to my colleagues” 

Site Manager - Dyer and Butler

“Stormsaver has helped us to upgrade the existing rainwater harvesting system. We desperately needed support and within one month they had attended site, carried out a survey, manufactured the new control panel, and installed and commissioned the system. Together the team at Stormsaver responded quickly, understood our requirements, and worked to ensure that we had the best solution. Their knowledge and expertise have resulted in us now having a fully functional, efficient rainwater harvesting system and we would highly recommend that other clients who need their existing rainwater system upgrading, contact Stormsaver for support.”
