Overview
- The blockage spans roughly 100 metres in east London and consists of congealed fats, oils, grease and non‑flushable waste.
- Thames Water issued a festive-season advisory urging residents to scrape plates, fit plughole strainers and avoid pouring gravy, cream or oils down sinks.
- The utility reports that fats, oils and grease cause more than 20,000 blockages annually across its network, accounting for about 28% of incidents.
- Blockages typically rise in December and January, with clearance over those two months costing about £2.1 million and wider annual sewer repairs running into tens of millions paid by customers.
- The find has been compared with Whitechapel’s 2017 fatberg, which stretched over 250 metres and weighed around 130 tonnes.
