These grim pictures show a fatberg removed from under a town said to be the same size as two Blue Whales.

The whopping 200 tonnes of unflushable waste was cleared from 50 miles of sewer pipes underneath Southend-on-Sea, Essex.

The shocking fatberg is roughly equivalent in mass to two blue whales - the largest mammals in the world.

It was cleared from the sewers in the town after a four-month operation.

And Anglian Water, which began the clean-up operation in December, and completed it this week, said some pipes were found to be up to 85 per cent full of unflushable materials.

The waste, once removed, was "roughly the equivalent of two blue whales", the company said.

The water company says that as well as plenty of the 'usual culprits' such as wet wipes and sanitary products, officials also found tools, toys, concrete, and even kitchen utensils blocking the pipes.

But thankfully, only 10 small repairs were required and no major issues were found during the project.

The work, which took place across the town centre, was completed to help prevent flooding in the area, which is often caused by a build-up of unflushables in the pipes.

Fat, oils and grease and other unflushables were detected across the network.

These were at the highest volume within the town centre and at the pumping station, with 15 tonnes of fat being cleared from the pumps alone.

Ben Hatfield-Wright, Water Recycling Network Efficiency Manager for Anglian Water, said: "We have been astounded by the amount of unflushables found in Southend-on-Sea.

"In addition to the wet wipes and sanitary products which we find are the usual culprits for blockages we also found concrete, tools, toys and kitchen utensils."

The water company will now be installing 24 sensors across the 80km network to monitor flow, levels and temperature, to ensure the pipes keep flowing.

It will enable engineers to identify any emerging issues before they cause problems.

Any areas showing signs of deterioration will be investigated to find the source of the issue, and all customer connections to the mains in the area will be checked.

And Anglian Water is asking residents to help keep the sewers clear and free of blockages by only flushing the 3Ps down the toilet - poo, paper and pee.

Anything else, including wipes, cotton buds and sanitary products should go in the bin.

Only used water should go down the sink - fats, oils and grease should be saved to reuse in cooking and baking.
