False teeth, mobile phones and a life jacket are among the bizarre items pulled from the sewer network at the city’s water treatment plant.

Southern Water says it removed 6,000 tonnes of wet wipes from the network in just eight months, which if laid out would stretch 2.75 kilometres.

The company also regularly removes large cuddly toys and mobile phones from the sewer at its treatment plant in Peacehaven and has recently found a set of false teeth and a life jacket in the system.

Southern Water has slammed people for clogging up the pipes saying they are playing “Flushian Roulette”.

Matt Collins, field customer engagement officer said: “We’ve had some unusual items found in the sewers, they have included false teeth, mobile phones, toys and even an inflatable life jacket.

“Other strange items include a set of Christmas tree lights and mobile phone, from the same blockage. We’ve also found a pickaxe end in Portsmouth and a pair of jeans in Southampton.

“Dropping wet wipes and kitchen grease down toilets and sinks causes sewer blockages and pollution incidents.

“You’re really playing ‘Flushian Roulette’ as that blockage might be in your sewer pipe leading to internal sewer flooding, which is a truly distressing thing to happen.

"We have contact with around 25,000 customers a year through door knocking, delivering talks, attending events and carrying mini projects within selected catchment areas. We have also seen sewage blockages reduce by 20 per cent as a result. Food business blockages have also fallen by 25 per cent."

Southern Water says it clears more than 23,000 blockages and surveys 2,700 on its network each year.

The company said that 66 per cent of blockages are preventable.

It comes as Eastbourne Borough Council called on Southern Water to “urgently improve” water quality.

The council criticised the water company for discharging water containing sewage into the sea in Eastbourne for a "staggering" 434 hours last year.

It said many Sussex swimming groups now have to check the water quality before entering the sea.

Eastbourne Borough Council has now passed a motion demanding that Southern Water starts the work needed to improve water quality.
