Helping Veolia Water save 1.5 million litres of water a day

24 January 2012

Veolia Water has made savings in excess of 1.5 million litres of water a day - nearly £100,000 a year - following the roll out of i2O Water’s integrated network monitoring system across 31 Veolia Water sites in the UK.

Veolia Water, which provides water and wastewater management services throughout the UK, approached the provider of water network monitoring solutions in August 2010, following very large and unpredictable demand. It experienced periods when it was necessary to supply higher quantities of water to one area to address these increased demands, which, in turn, lowered the pressure of the available water in the network. It was necessary to set water pressures very high during this period, which were too high for the rest of the year and led to excessive burst pipes and water loss. Veolia Water need to be able to actively manage and control the pressure to address this fluctuating demand.
To help solve this problem, it installed i2O’s integrated network management system and was able to remotely reduce burst mains and leakage and improve response to network issues. The solution gives the ability to proactively control and optimise the water pressure, which helps Veolia Water optimise the management of its network. The reduction of background water leakage on the first system alone was estimated at 300,000 litres a day following installation and optimisation, and proved such a success that Veolia immediately rolled out the i2O technology into another 30 areas by the end of 2010. This has resulted in a leakage reduction of 1,500,000 litres of water.

Stephen Eeles, leakage and network operations manager at Veolia Water said: “The implementation of the i2O solution has enabled us to proactively address pressure management issues across the Veolia Water network, enabling us to focus on problem hotspots where we were seeing supply issues due to demand spikes. This has enabled us to realise significant water and cost savings and, importantly, improve the service we are able to offer our customers.”
