A massive accumulation of discarded wet wipes, described as 'Wet Wipe Island', has formed on the southern foreshore of the River Thames near Hammersmith Bridge. The pile, roughly the size of two tennis courts, has become a grim new landmark in London, drawing attention to the environmental impact of flushing non-biodegradable products.
The Port of London Authority (PLA) is leading a cleanup operation expected to remove over 180 tonnes of wipes—equivalent to about 15 double-decker buses—from the river over the next month. Using a 'rake-and-shake' method, the PLA is sifting the wipes from sediment, which will then be sent to landfill. The cost of the operation is estimated to be in the hundreds of thousands of pounds.
Environmental charity Thames21 has also been involved, with volunteers manually collecting around 140,000 wet wipes from the Thames since 2017. The wipes, many containing plastic, are flushed into the sewage system and overflow into the river during heavy rain. They accumulate at slow-moving bends, harming wildlife and potentially humans by entering the food chain.
Thames Water clears 3.8 billion wipes from its network annually at a cost of £18 million. Despite government pledges to ban plastic-containing wet wipes, progress has stalled since the last general election. The PLA notes that while the Thames has recovered from being 'biologically dead' in the 1950s, challenges remain from ongoing pollution.
