Thames Water uses SpillSens to battle blockages
Thames Water SpillSens

HWM is pleased to be working closely with Thames Water to install our intelligent new SpillSens technology into their sewer network, helping in the battle against blockages caused primarily by cooking fat and wet wipes.

Over 300 SpillSens devices have been installed in trial areas across Henley (where removal of a giant fatberg from the network caused major disruption in 2017) and in parts of London.

SpillSens uses digital positioning technology to monitor rising levels within the sewer system and delivers an alert to the customer should regular levels be exceeded.  This information helps the customer, in this case Thames Water, to pinpoint emerging problems before they develop.

On average, Thames Water spends £18 million every year clearing 75,000 blockages from its sewers, unclogging five house blockages and removing 30 tonnes of material from just one of its sewage works every day.

Discussing the installation of SpillSens, Thames Water Operations Manager Anna Boyles explains that “these new sewer level monitors are the very latest bit of kit – they’ve only just come onto the market”.

“They have a longer battery life, are smaller and easier to install.  The data they provide will gibe us a much better picture of what’s happening in our sewers and will help us to nip blockages in the bud before they cause problems”.

With plans for further trials later this year, Thames Water at the forefront of embracing digital technology and the impact it can have in protecting their network and preventing the flooding and pollution associated with blockages.
