HUGE balls of human waste the size of five elephants are clogging our drains, water company bosses warned today.

The vast ‘poobergs’ have to be blasted with high-pressure hoses after people flush condoms, sanitary towels, wipes and nappies down the loo.

Anglian Water said at one of its sites in Lincoln staff filled three and a half skips with a pooberg the equivalent of five elephants.

They've pleaded with people to stop flushing the objects and warned if it does not stop it could cost families and companies £15 million a year in extra bills.

The company say they have to deal with more than 30,000 blockages a year - and four out of five are caused by people putting sanitary towels, wipes and soiled nappies down the loo.

One photo shows a six-tonne skip which collects 'unflushables' at a recycling centre run by Anglian Water.

They had to ship in a specialist robot with a high-pressured jet from Holland to zoom along the blocked sewers to blast the fatbergs into chunks.

More blockages are caused by homeowners pouring cooking fat down the sink and last month a fatberg as big as a transit van had to be blasted with power jets.

A spokesman said: "This can not only cause problems for people at home, but clogged sewer pipes can cause flooding of untreated sewage into homes, gardens, streets and even end up in rivers, the sea and on beaches."

They added: “Every year Anglian Water staff clear thousands of blockages from the region's pipes.

"There are more than 30,000 blockages a year...eighty per cent of which are caused by wipes and fats.

"This adds £15 million a year on to customers' bills.

"If fat ends up down the sink it can cause a major headache.

"It sets hard in the pipe and mixed with other unflushables such as baby wipes and cotton buds, causing blockages.

"This not only causes problems for you at home, but clogged sewer pipes can cause flooding of untreated sewage into homes, gardens, streets and even end up in rivers, the sea and on beaches."

Thames Water reckon around 20 tonnes of fat - the size of two double decker buses - end up in the sewers of Oxford every year.

Sarah Dobson, an Anglian Water spokesman, said: "You can help avoid problems by not putting things like wipes down the loo and leaving fat from cooking to solidify before scraping it into your bin or recycling caddy."

Earlier this year a fatberg led to a couple living in Oxford to be flooded with a poo-nami of raw sewage for the third time since 2003.

Hoonie Feltham, 65, said: “It was awful - we had raw sewage flooding into our basement and we have a room we often rent out down there.

"It's happened three times now since 2003 and I am at a loss as to what to do.”

Last year, a fatberg the size of a Boeing 747 was discovered beneath the streets of Shepherds Bush in West London.
