Flow Controls Dedicated to SuDS

Controflow® control chambers are specifically designed for shallow SuDS elements to manage rainwater runoff, including permeable pavements, swales and basins. They feature orifices, guarded where necessary, which are accessible for demonstrating straightforward compliance to local authorities as part of the SuDS design approval process.

A universal stainless steel mesh SuDS Basket, for filling with stone, acts as an attractive pipe inlet or outlet within landscaped SuDS features.

Controflow universal stainless steel mesh SuDS Baskets - for filling with stone - act as attractive pipe inlets or outlets, or enable diffuse water flows down slopes, avoiding erosion. Controflow Roof Outlet Control and/or Overflow Units have been specifically designed for blue and green roofs, and are easily installed without interfering with existing roof outlets.

Why We Need Flow Controls

Why We Need Flow Controls 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…

How orifice flow controls work

How orifice flow controls work The Controflow® orifice design is based on well-established flow rate performance characteristics using the standard orifice equation shown below. 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…

Controflow improves permeable paving

Controflow improves permeable paving 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.
