SuDS are now a Government requirement on many developments, approved and often adopted by local authorities. The key to successful SuDS is water storage strategically deployed around a site within SuDS elements – such as swales, basins ponds and, particularly, permeable paving – forming discrete sub-catchments with flow controls. Controflow…

The Controflow® orifice design is based on well-established flow rate performance characteristics using the standard orifice equation. The Controflow® orifice profile is recognised as delivering a standard 0.65 coefficient of discharge irrespective of orifice size. The performance of Controflow® mimics the gradual response of natural drainage particuarly during short duration…

Controflow® control chambers can transform the multifunctionality of permeable pavements enabling them to be used for demonstrable water storage in sub-catchments around a scheme and to maximise storage on sloping sites.

Controflow SuDS Baskets are manufactured in stainless steel mesh for filling with stone and act as attractive inlets or outlets that protect pipe openings (as well as flow control orifices), or as erosion control to enable gentle water flows down slopes.
