The critical nature of these valves made them an ideal trial location for AVK UK’s smart air valves. The specified valves, installed by Mott Macdonald Bentley (MMB), included both internal sensors to track the performance, alert on any faults and record the pressure of the valve and an external sensor to monitor the water level in the chamber. The chamber was potentially prone to flooding in the event of high rainfall.
The smart air valves provide feedback on a range of key operational parameters. These parameters include: overflow, leakage, blockage, pressure, tampering, tilt/shock, low battery and, with the addition of the external sensor, chamber flooding.
When smart air valves are installed in remote locations where communications infrastructure may be limited a multi-SIM card is an option. If chamber lids are particularly thick and risk blocking GSM coverage an external antenna can be installed.
Dave Hurley, AVK UK Business Development Manager – SMART Water, worked alongside Yorkshire Water and MMB to ensure the smart air valves met the requirements of all parties:
‘The AVK UK smart air valves are, I believe, the first to be available in the UK. The sensor and communications aspects of smart air valves means there are far more boxes that have to be ticked before a water company is willing to trial them. Covid-19 meant the product demonstration had to be delivered online in a ‘classroom-based’ format.
If any of the sensors, internal or external, is activated, email and text messages are sent to all interested parties. As digital communications are involved, I worked closely with Yorkshire Water to ensure they were confident the smart air valves met their cyber-security protocols.
As it is a trial installation, I received notification of all the alerts alongside Yorkshire Water’s engineers. The recent heavy rainfall meant the external sensor registered a flooded chamber alert. The internals sensors however did not register any faults, so it was clear the issue was high river level not a leaking air valve. It was really good to know the smart air valve was doing its job and enabling Yorkshire Water to monitor and react correctly to the problem well before there was any danger to the River Wharfe.
I would like to thank Ian Jowitt and Dave Athersmith from MMB and also Pamela Ajayi and Sohail Tabassam at Yorkshire Water, with their assistance in making this trial a success.’
