Prefabricated Shallow Flow Control Chambers
SuDS Flow Control Chambers play a vital role in managing surface water runoff and regulating discharge rates within Sustainable Urban Drainage Systems (SuDS). Designed to control the release of stormwater from swales, ponds, permeable pavements, attenuation tanks, geocellular storage systems and underground drainage networks, flow control chambers help reduce flood risk, protect downstream infrastructure and support planning compliance.
Our SuDS Flow Control Chambers are engineered to achieve specified discharge rates and greenfield runoff requirements. Widely used on residential, commercial and infrastructure developments, they form an essential part of modern stormwater management systems by providing reliable, low-maintenance control of surface water flows.
SEL supplies a comprehensive range of SuDS Flow Control Chambers designed to support effective stormwater attenuation, surface water drainage and sustainable drainage strategies for projects throughout the UK.

Product Information
SUDS01001
Flow Control Chamber
A standard, shallow flow control chamber with an un-guarded single orifice (to specified diameter), designed to manage outflows from permeable paving or other open graded sub-base construction. Its small size and low cost make it ideal for check dams between permeable paving compartments. This product does not incorporate an internal overflow.
SUDS01101
Flow Control Chamber
A small flow control chamber with a 110mm diameter inlet and protected orifice located at the base of a removable flow control tube. The flow control tube allows access to a deeper chamber where pipe inlet depth is obstructed by other construction factors like kerb haunching or existing pipe work. The removable flow control tube is perforated to protect the orifice in the base of the tube.
SUDS02005
Flow Control Chamber
A flexible, universal flow control chamber suitable for any SuDS technique, with level inverts. The slide-out centre plate contains a circular orifice (to specified diameter), protected by an upstream guard, and acts as an overflow weir. 3 x 160mm diameter inlet pipe connection stubs offer layout flexibility. Suitable for depths ranging from 537mm to 1.2m (finished cover to base).
SUDS02008 Flow Control Chamber
A standard flow control chamber with a single, guarded orifice (to specified diameter), designed to manage outflows from permeable paving or other open graded sub-base construction. Stepped inverts simplify the transition from shallow permeable paving to deeper constructions. The protective guard and orifice cap are removable, and the rodding access upstand can act as an overflow.
