In the Finals - the IET recognises RDN’s Retrofit Wastewater Flow Regulator

Sep 30 2022

Against tough competition, the Wastewater Flow Regulator has been selected by the IET for its Smart Tech, plus Sustainability and Net Zero Innovation Awards to be held this November for its ability to reduce pollution, sewer flooding and ultimately plastics in the oceans. The latter has been the subject of several previous IET innovation awards and was one of the inspirations behind the project.

Recently in receipt of its UK patent last April,  the Wastewater (Sewer) Flow Regulator has already been successfully deployed by Anglian Water at several locations and is now looking for a home in sewers across the UK. 

RDN’s founder and managing director Eur Ing Brian M Back stated that deployed in the right location, the Wastewater Flow Regulator can make a real difference. Compared to penstocks, the regulator from its onset was designed to be retrofit, low carbon, lightweight, easy to control and maintain as the regulator part is retractable from the surface. A key part of its patent is its failsafe overflow weir, and the use of the existing invert as part of the seal thereby eliminating any discontinuity in the invert that could lead to rags or FOG build-up leading to a blockage.

As there is no need to construct a dedicated chamber or to provide mains power, the embodied carbon and installed costs can be as low as 10% of fitting an equal sized penstock. Plus, installation timescales and disruption can be significantly reduced too. The opening and closing of the regulator can be via any downstream level sensor. These are usually deployed at the pinch point in the network and are linked back using real-time radio telemetry. 

RDN are actively looking for partners and distributors across the UK, to support their mission of improving environmental sustainability.
