The Wilton Science Park houses companies that specialise in life sciences, sustainable processing and manufacturing technology. To secure the area's water supply, AVK valves and pressure sensors now send alerts to the operation team when necessary.
In 2019, a burst water main feeding the Wilton Science Park caused comprehensive and high-cost damage. The resulting insurance investigations led to the Park’s insurers insisting that a contingency shut-off valve be installed as part of the reinstatement works. A complicating factor, however, was that the Park’s fire main was fed by the same water supply and could, of course, not be compromised.
Valve and sensors product selection
The chosen solution was to install an AVK series 879 diaphragm control valve fitted with VIDI flow and pressure sensors. The valve and sensors were linked to an AVK UK Smart Water PMD (Pressure Management Device), and the product installation was located in an above-ground housing for ease of access and maintenance.
Instant flow and pressure level alerts, and leakage detection
The PMD and VIDI sensors send alerts to the Park’s operations team whenever flow and pressure levels breach the agreed levels. If there is a leak, the PMD can automatically reduce pressure and alert the operations team who are able to close off the flow from their mobile phones or laptops, all achieved via remote communications to the valve. If changes in flow and pressure are due to the event of a fire, the valve remains open.
The new arrangement has already shown its worth in normal working conditions: the VIDI sensor detected a change in the flow, indicating a possible leak on the network. The PMD then reduced the pressure whilst the leak was detected and remedial measures taken, saving a significant amount of water and important resources.
