Sewer Flow Controller Sewer Flow Regulator


Patented, Proven, Low Cost, Low Embodied Carbon Sewer Flooding & Pollution Reduction. Retrofit Smart Networks Help Optimise Sewer Capacity, Reduce Sewer Flooding, CSO Operations and Reducing the Volume of Plastics Entering our Oceans using a Wastewater Flow Regulator – as a Sewer Flow Regulator. 

British, Patented Technology to the Rescue, the Wastewater Flow Regulator is equally at home in a sewer or surface water drain.

This retrofit technology is the Low Carbon, Low Cost way to combat sewer network flooding and spills of plastics in the oceans via CSO overflows. First conceived in 2018 the Sewer Flow Regulator [SFR] unit is the perfect low carbon, low energy actuator for creating smart sewer and drainage networks.

In service proven at several locations since 2018 the regulator is compatible with a variety of Smart Network Sensors such as the Radio Data Networks BDT, which provides virtual real-time feedback of level.

Need for Sewer Flow Regulation

As the picture illustrates the issues are clear however controlling an open-loop system, i.e. the sewer networks requires a solution is can be retrofitted, has low embodied carbon, without the need for mains power and has the ability to receive local control signals

Retrofit Sewer Flow regulations

Having spent over 35-years in the Water and Wastewater sector the inventor came up with a solution to close all of the above issues plus has created a design that is truly affordable when compared to the alternative of creating new chambers, closing roads, over pumping, and all the disruption this involves.

Sewer Flow Regulator Innustration

Lightweight in construction the Wastewater Flow Regulator can be installed by hand without the need for a winch or crane, another carbon saving!

The regulator can be crafted / profiled to fit a existing sewer invert and benching and even can be retrofitted to plastic chambers.

The Patented overflow weir can be adjusted to set the spill point in the unlikely event of the regulator failing in the closed position.

Sewer Flow Regulator Networks

The controls for the Wastewater / Sewer Flow Regulator are Simple, on-off binary making the unit controllable from sensors such as the Radio Data Networks BDT, FDT and FST or alternatively directly from a telemetry system with nothing more complex than a digital output.

There is the choice of single point control  where the flow is inhibited by a single sensor or dual point control and the entire regulator and its controls can be solar powered.

Sewer Flow Regulator Control - Single Point


With dual-point control the flow can be modulated and levels controlled to prevent excess levels both up and down stream of the SFR.

The  examples below is a 225mm wastewater flow regulator installed into sewer to regulate the flow from the branch entering the chamber from the top.  Whereas the flow from the right is left unregulated.

Finally, who needs mains power. This can be a huge expense and result in months of delay, the regulator is perfect for solar operation and can be supplied with its own solar kiosk.
