SuDS and Stormwater Treatment Alarms

The penalties for breaching environmental consents or planning conditions for stormwater discharge now make the inclusion of good monitoring alarm systems essential on all pollution capturing devices. While the CIRIA SuDS Manual C753 doesn’t currently require alarms it is the responsibility of the design team and end client to ensure compliance with Environment Agency guidance, local planning & by laws and the Water Framework Directive at the point of discharge, making the requirement for monitoring and alarms critical. Where the design needs to comply with the British Standard BS EN 858, oil separators must be fitted with an oil alarm probe and control panel, DEFRA and the EA made this a legal requirement for oil separators in 2021. All oil separators must have an up-to-date service log available for EA inspection at any time. SPEL offers a full set of alarms for monitoring most of our stormwater pollution control systems giving clients and operators the peace of mind that the system is operating as designed. It is important that the recommended service intervals for all SPEL monitoring and alarm systems are followed to ensure peak performance and maintain the required water quality levels. Our technical team will be happy to help with questions on compliance, operation and maintenance. SPELGuard, our Commissioning and Service Team, will be glad to help setting up the system once the installation is complete.

*Optional flashing beacon (visual alarm).
**Optional visual and audible alarms.

idOil-OIL oil probe

Detects oil and indicates when the separator’s oil storage is full.

This probe is required in order for a treatment device to comply with BS EN 858.

idOil-SLU silt probe

Monitors the silt layer in the oil separator and indicates when the silt layer has reached its maximum level.

idOil-LIQ high liquid level probe

Indicates when the liquid level in the oil separator rises excessively e.g. in an outlet blockage situation.

Oil/Silt/High Level Alarm

The idOil Solar is a solar powered oil separator alarm, it’s ideal for remote applications/off-grid areas or where supplying a dedicated single phase power source is complicated.

The solar powered control system is a modular platform within the idOil range and can accommodate a range of probes and control panels to meet clients specific requirements. Please contact our team for more details.

As per the illustrations below, this system can be supplied as the basic solar panel platform or include an optional flashing beacon, it also has the added benefit of being able to connect to autodialler/3G modem. If the alarm is activated, the beacon light will flash and/or an alarm message will be sent via an SMS/mobile network, this alarm message can be sent to up to five different pre-programmed mobile numbers.
