VINCI Facilities in the UK, manages around 37,000 assets in the Royal Parks (such as fountains, statues and royal memorials for example in Kensington Gardens) and the water features are fed by the Longford River. If you have ever travelled in west London, there is every likelihood that you have crossed the Longford River – probably without realizing it. Built for King Charles I in 1638/39, the river travels from near Heathrow airport to feed the water features in Bushey Park and Hampton Court Palace. Maintenance and ongoing management of the Longford river are required as it helps protect industrial and residential areas, which the river passes through, from flooding and helps preserve the ecological status of the river. Checking the status of the Longford River used to be extremely effortful as 3 staff continually had to walk the length of the river and visually inspect it. They had to look for changes in water levels caused by heavy rain, weed growth or illegally dumped waste such as mattresses and sofas.

VINCI Facilities’ account manager James Lyall believed that the process would be more efficient and cost savings would be achieved if the water levels could be remotely monitored by his team. He therefore contacted a number of potential technology providers, reviewed the available options, and chose OTT Hydromet as the preferred supplier. “In addition to robust, reliable water level measurement technology, we also needed a system that would provide easy access to data including historical trends, and issue alerts when water levels approach pre-set alarm levels,” James explains. “One of our key requirements was a web-based portal – providing a facility for our staff, our client’s staff and the public.” The OTT ecoLog 500 was chosen for the Longford River as it brings all this and is additionally drift-free, does not require recalibration, provides easy access to data including historical trends, and issue alerts when water levels approach pre-set alarm levels

OTT supplied, installed and commissioned the monitoring network, and provides ongoing maintenance with 6-monthly visits.
