Oriflo Flow Control Chambers for managing surface water flows on site

Oriflo Flow Control systems are a range of orifice plate flow control chambers, designed to support SuDS Management and the sewer infrastructure as part of a designed attenuation system, helping prevent flooding by controlling the flow into the main sewer.

The use of orifice plate flow control chambers has proven to reduce the land requirement and make significant savings on the the cost of larger flow control units and chambers at the final outfall of the site and the use of strategically sited Oriflo units can help optimise SuDS.

We manufacture two designs of Oriflo –  P Series (Unprotected Plate) and C Series (Protected Plate).

Oriflo P Series (Unprotected Plate)

Designed to be used where silt and debris has already been removed upstream and there is little chance that the orifice could be blocked. The P series is ideal for installation in cellular/crate type attenuation and from permeable paving.

Oriflo C Series (Protected Plate)

Designed to be used downstream of open type attenuation schemes like basins, swales and large oversized pipes, where silt and debris could be flushed into the chamber during rainfall and storm conditions. The C Series range all have a protective SILTBLOK screen wall, that protects the orifice itself from blockage. The SILTBLOK technology allows water to flow through the screen freely but filters out silt and debris.
