Thames Connect

eight2O has developed a new tool – ThamesConnect - which shares data from multiple teams across eight2O, Thames Water and the Infrastructure Alliance in one simple display. This enables teams to see where other work is planned or needed, giving them the opportunity to come together and coordinate their work; saving money and reducing disruption to customers, as there’s nothing more frustrating than seeing a road dug up once, then dug up soon after by another utility. And importantly, there are also benefits to health and safety and reduced carbon emissions.
