TL;DR: HSG274 does not ask you to run a tap for a fixed number of minutes. It asks you to flush until the temperature at the outlet stabilises and is comparable to supply water. That means the legionella flushing test is, literally, a temperature measurement. It is also the one control almost every estate records…
TL;DR: The UK’s statutory river standard for oxygen is not an average. It is a 10 percentile, which means the classification is decided by the worst tenth of the readings. In a river those readings happen shortly before dawn, when nothing has photosynthesised for eight hours and everything has carried on breathing. A grab sample…
TL;DR: A pressure transient travels along a metal water main at around 1,000 metres per second and is over in a fraction of a second. A logger sampling every 15 minutes has roughly a one in a million chance of being awake when it passes. The interesting part is what the UK’s own review concluded…
Short answer: the WS303 (£41.90 ex VAT) is the cheap, small unit you scatter under appliances, sinks and boilers. The EM300-SLD (£53.87) is the same job in an IP67 housing with a proper probe — for plant rooms, voids and anywhere damp or dirty. The EM300-ZLD (£71.82) swaps the probe for a sensing cable, so…
Last updated: 13 July 2026 TL;DR: Escape of water is one of the costliest risks a UK commercial building faces: insurers pay out around £1.8 million every day for the damage it causes. Modern water leak detection puts battery LoRaWAN sensors in plant rooms, risers, ceiling voids and server rooms, alerts your team within minutes…
Non-revenue water loses UK utilities 2,617 Ml a day. See how acoustic loggers, pressure sensors and DMA monitoring over LoRaWAN cut leakage to Ofwat targets.
Storm overflow monitoring explained: the Environment Act duties, EDM, water quality sensors and the LoRaWAN sensor-to-dashboard stack that delivers compliance.
Last updated: 1 July 2026 TL;DR: IoT flood monitoring uses battery-powered water-level sensors, rain gauges and flow meters that report over low-power radio to a central dashboard, giving early warning of rising water. In the UK, where 6.3 million properties sit in areas at risk of flooding, these systems cut response times, protect assets and…
The utilities industry faces growing pressure to act faster, operate more efficiently, and reduce the need for site visits. At INDIOTT, we harness proven IoT technologies — like web-enabled solenoid valves — to deliver practical, cost-saving solutions for these challenges. These valves are already delivering real-world impact in live field deployments across the UK. Solving…
Over 18 months, PSI Tech has been working on a proof of concept trial for a sewer vacuum system in Lincolnshire for Anglian Water, to prove that a combination of low cost pressure, vacuum and flood sensors and an end to end remote asset monitoring platform greatly minimises the significant time and effort spent on…
