A look back at the Water Leak detection progress in Device & Server Rooms
In the late 1970s, water leak detection came about when machine rooms were in their infancy. Computer rooms, as they are today, contain air conditioning, which includes humidifier water and also cooling water. A raised floor was and is still used to hide all utilities, due to the large number of power cables, data cables and water pipes required in the room. Unfortunately, once the power/data links were submerged in water and the machine stopped running, any water leakage under this elevated floor would not be found.

Water was detected using spot probe sensors up until the mid 80’s. Either an engraved PCB or two metal electrodes will be composed of these modules. Using a DC voltage in one sensor, sensing for water was conducted when searching for a return signal in the other. There was no return signal in the return sensor, no water present. Erosion of the sensors due to electrolyses and the restricted area of water detection, water could flow away from the sensors and not be detected until too late, was the issue using this type of device.
The water detection cable was established during the mid-80s. The benefit of this method of sensing is that water is detected along the entire cable length. This allowed surrounding areas or equipment containing water to ensure that leaks were identified no matter the direction in which the water flowed.
Progress has mostly been with the warning panels and the reporting of water leakage from the mid 80’s up to today. You can be contacted, emailed today, receive a phone call, record it on a building management system, or just have a basic buzzer and lamp.
My participation in detecting water
In the late 1970s, while working for Vikingshaw Products Ltd, I was first asked to develop a water detection device. At that time, our mother business, Vikingshaw Ltd, built computer rooms all over the country and supplied them with power distribution units, etc. For sensors and control units with a simple buzzer and lamp, the first systems were simple in their nature, being DC based with PCBS. Unfortunately, it wasn’t long until I realized that DC was not the best way to detect water, because if left in water for a few hours, our sensor copper tracks would vanish. It was from this point on that I used the sensors’ AC signal to avoid them eroding away. I entered into a partnership in the early 1980s and began a business called Wayscale Ltd.
