Sewer Flood Monitoring & Alarms

Flooding can occur because of blocked sewage drains and much property damage is caused when flood water rises through sewage or waste water pipes.

If you need time to erect flood protection equipment, or you want early warning in case something happens unexpectedly during the night or when a building is not in use (weekends/holidays), then you need to install monitoring equipment.

We design & manufacture in the UK a complete range of monitoring equipment to suit all requirements. These can be easily tailored to suit your individual requirements. They are typically used by businesses, public sector organisations and communities.

The range includes high performance radio telemetry based, wide area, Flood Warning and Flood Alarm Systems for use in Industrial and Community based flood warning schemes. This operates over a secure radio telemetry band operating under an exclusive Ofcom licence.

We can offer Mixed Flood Alarm, Storm Drain and Sewer Surcharge Alarms on one platform.

Many communities and businesses suffer flooding through the sewers and storm-drains backing up into their properties. To cater for this our flood alarm systems can be also equipped with our BDT blocked sewer detectors that can simultaneously report both surface and sewer flooding.

Our Resilient Communications:

Our systems can be constructed to operate from a single or multiple locations, with flood sensors distributed over areas measuring many square km/miles. Warnings to staff and public can be delivered using a variety of media including e-mail, SMS text, audible siren and flashing lights etc.

We offer one of the highest levels of resilience when it comes to communications from our flood sensors.

Rather than using the cellular telephone networks for the first and most crucial part of the link, our systems are supplied to operate on a secure licenced radio channel. Not only does this eliminates the reliability and obsolescence issues associated with the cellular networks but also permits systems to be installed in remote locations without requiring a SIM card in every detector. Finally, our communications are totally immune from cyber attack.

The in-sewer / drain flood alarms are mounted under manhole covers and can report back (via our solar powered repeater/booster stations) the presence of a storm surcharge which could lead to a breach of flood defences.

Technical information

The flood alarms are 100% battery powered and the internal electronics are fully encapsulated to exceed the IP68 standard in order to withstand prolonged submersion during the flood. The system operates using our proven BDT sensing technology that has no moving parts eliminating the risk of sticking float switches a common problem that is often caused by insect, leaves and dirt infiltration. BDT technology is also generally outperforms conductivity type systems as it is immune to triggering by wet leaves. Battery life is typically 10-years and unlike GSM/SMS based systems which are both power hungry and expensive to operate, our power efficient design and lean radio protocols permits each unit to automatically send a uniquely coded health message every 5 or 15 minutes (version dependant) which the receiver station automatically constantly monitors to confirm the system is operational.
