Southern Water’s AI-enabled smart sewer system led to more than 4,000 interventions in the past year, enabling its teams to remove blockages.

Anglian Water and Environmental Compliance and Services (ECAS) have saved the East of England’s sewers from 10 million litres of fat, preventing avoidable blockages and helping protect homes, businesses and the environment from flooding and pollution.

Thames Water engineers have unearthed a half kilometre wall of congealed fat lurking beneath the roads outside Heathrow Terminal 5, a blockage big enough to stretch between two airport terminals.

Anglian Water has teamed up with The Big Table Group (which operates several major restaurant chains, including Bella Italia), GreaseTech Drainage Solutions and ECAS (Environmental Compliance and Services) to protect the East of England’s sewers from blockages – which can be caused by fats, oils, greases and other unflushables, including starch.

A 120 tonne fatberg, equivalent in size of a blue whale, has been removed from a large trunk sewer in Oxford. Clearing the fatberg required a coordinated effort from multiple Thames Water teams and contractors, highlighting the scale and complexity of the operation.

Artificial Intelligence installed by Southern Water beneath a West Sussex community’s feet saved homes from flooding when a fatberg formed.

Northumbrian Water has named Esh Construction as its sole delivery partner for its Wastewater Networks Framework, a planned and reactive repairs and maintenance contract across the region’s wastewater network.

A sewer robot that inspects pipework and raises blockage alerts before flooding occurs is to be deployed in a live network for the first time.

An innovative technique trialled over the last 12 months in part of central York to reduce blockages caused by fats, oils and greases in the city’s sewers has reduced pollutions and sewage escapes caused by fats to zero.

So far this year, Anglian Water has cleared over 13,565 blockages caused by wrongly flushed items, as well as build-up of fats, oils and greases (FOGs).
