British designed, multi-award winning, and GB Patented (2574173) Wastewater Flow Regulator, also known as the Sewer Flow Regulator (SFR) for short, is a cost effective, retrofit, automated flow control device aimed at converting new or existing gravity sewers to become part of a smart sewer network.
Strategically installed in a sewer, Sewer Flow Regulators can help reduce incidents of sewer flooding and/or the activation of CSO overflows by throttling back and/or clipping peak flows under the control of real-time level sensors, network telemetry or smart catchment models.
When mounted on the inlet, the regulator is supplied with a fixed body which mounts over the invert and tight up against the chamber wall. This body typically includes an overflow pipe which is adjusted to prevent spills. The regulator slides into two guides at the bodies outlet. The blade of the regulator is driven up and down in relation to the invert, to either cut-off the flow completely or leave a residual defined pass forward flow.
