SuDS-compliant attenuation tank systems for new builds, extensions and commercial sites across Herts, Bucks and Beds.
Most new builds, extensions and commercial developments now require an attenuation tank to control surface water runoff and meet Sustainable Drainage Systems (SuDS) guidance. We design and install attenuation systems sized to your site, your planning conditions and your discharge rate.
From modular crate tanks to large pre-cast concrete systems with flow control chambers, we deliver complete attenuation installations — including excavation, geotextile wrap, pipework connections, flow control devices and full reinstatement.
