Radio Data Networks - Sewer Flood Alarms & River Level Monitoring

From flood and river level measurement and alarms – through to sewer alarms and automated drainage flow containment systems (valves) , Radio Data Networks offers a unique portfolio of UK designed and manufactured systems, many of which are 100% bespoke. Thanks to our excusive Ofcom National radio licence we can also deliver alarms in areas devoid of cellular coverage.


Customers include utilities, government agencies, local authorities, schools, hospitals, universities, national retail outlets, food chains, right down to private individuals and flood groups.

Radio Data Networks are the UK’s largest manufacture of real-time telemetry based sewer flooding alarms. Our clients include the four of the UK’s largest Water Utilities, industrial, retail, the restaurant trade, Universities, Local Authorities, Schools and members of the public.

Aside from sewer flooding systems can be configured to detect surface flooding, flooded culverts, flooding in basements, monitor river levels, detect flooding in ducts and tunnels. Systems operate using multi award winning sensor technology and communicate using wireless technology eliminating the need for cables and mess. Sensors can be placed in culverts, below manholes, under bridges, in stilling tubes, in drains, on river banks, etc. Sensors are also available certified to the ATEX Zone 2 making them suitable for mounting in the majority of sewer locations.

There are a wide number of receiver options including interfaces to existing building management / alarm systems, data commentators for uploading to remote web sites right through to our most popular solution the 4-zone flood sentinel.

The Food Sentinel is a simple to install wireless flood alarm system with sensors that can be deployed to protect a property against surface water flooding, river flooding, groundwater flooding and sewer flooding.

The Flood Sentinel comprises of a mains powered audible alarm receiver housed in a smart stainless steel wall box, complete with antenna port, status LEDs, sounder and latching relay with dual contacts for operating external devices such as telephone automatic communicators, sirens and beacons. Up to 4-wireless flood sensors can be ordered with the sentinel for installation in an around a property in locations such as basements, sewers, drains, culverts and on river banks.


The wireless flood sensors are totally sealed and can withstand prolonged submersion without damage. Further the sensors comply with the ATEX directive making them safe for deployment in locations where there is an occasional risk of potentially explosive gas buildup, such as sewers.

River Level Monitoring & Alarm System

A wide area river level monitoring and alarm system designed to deliver river height readings 24/7 as part of an integrated flood warning system. The system data can be fed directly to a PC monitoring package, exported to a remote cloud based web server or interfaced as an analogue level to an existing SCADA or telemetry system.

Utilising state of the art microwave radar technology the system is capable of delivering river levels to mm accuracy without being affected by wind or rain. Optionally bu using our wireless technology data can be delivered from areas devoid of cellular coverage ofer distances of up to 10km, making the system ideal for both up stream and down stream monitoring.
