Blocked Sewer Alarms and Blocked Drains we have Proven Technology, with a 10-year plus service history.
We have a wide portfolio of UK Designed and Manufactured Blocked Sewer Detectors / Transmitters and Receivers to help customers detect and report regular everyday occurrence from becoming an embarrassing and economic disasters! This helps to prevent pollution too as many do not realise that blockages and sewer overloads are one of the primary causes of plastics getting into our oceans.
Sewers and drains block regularly. In fact look at the old Yellow Pages directory and you will see more entries to Drain Blockage and Cleaning section than almost any other trade. Backup and surcharge occur for a variety of reasons ranging from sewer collapse, tree roots through to the build up of FOG (fat, oil and grease), congealed macerated pulped hospital waste, wet wipes, etc. Early warning of sewer blockages or partial blockages can be detected by monitoring the sewer levels at various locations over a site within manhole chambers in order to detect abnormally high levels both during dry and wet weather conditions.
Developed in 2010 and originally supplied exclusively to the water utility sector – the BDT technology is probably the most widely deployed solid-state wireless blocked sewer alarm and is used across the board from the Water and Wastewater Utilities, Hospitals to Railway Stations.
Radio Data Networks award winning BDT [Bulk Dielectric Transducer] is acknowledged to be the pioneer of blocked sewer detection technology. First introduced in 2010 it has proven far more effective than ultrasonics or float switches. It’s ultra low power operation gives instant alerts whenever a high level is detected.
Using wireless technology it is able to operate from below manhole covers without the need for cables and wires. It can even detect blockages and stoppages in sewer mains / lines buried under floors of virtually any construction and with any type of surface finish without the need to run cables and to construct ducts in floors.
First introduced in 2010, the Radio Data Networks BDT saw the dawn of a radical approach to generating sewer alarms and sewer monitoring the BDT Blocked Sewer Alarm Transducer. The BDT crucially included a fully battery powered sensor technology and a real time communications system that permitted sewer levels to monitored for blockages 24/7 almost anywhere on a site irrespective of its size, from below manhole covers, without modification or the need to run cables. Now in 2019 and circa 5 billion messages later the BDT has proven itself to be reliable, easy to install and effective.
Messages from our Blocked Sewer Alarm systems can be delivered locally to alarm panels , flashing beacon controllers, or remotely to external solar powered flashing beacons or into a buildings BMS system or SCADA. Using a PC based software package Sentinel FM and a radio interface to the PC we can also offer 24/7 monitoring and data logging with graphical visualisation. Link to Sentinel FM.

We also offer a range of hand portable systems that can be used on foot or from a vehicle.
