Blocked Sewer Alarms, Proven Technology! We have a wide portfolio of Blocked Sewer Detectors / Transmitters and Receivers to help customers prevent a regular everyday occurrence from becoming an embarrassing and economic disaster!
Sewers and drains block, backup and surcharge for a variety of reasons ranging from sewer collapse, tree roots through to the build up of FOG (fat, oil and grease), 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 now used across the board from Hospitals to Railway Stations.
We have industry leading and proven technology to detect blockages and stoppages in sewer mains / lines buried under floor of virtually any construction and with any type of surface finish without the need to run cables and to construct ducts in floors.
In 2010, Radio Data Networks introduced a new radical approach to generating sewer alarms and sewer monitoring called the BDT Blocked Sewer Alarm Transducer. This 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 2017 and circa 2.5 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.
