Major new development in the fight against fatbergs

Water UK has recently announced the publication of a new official standard identifying which wet wipes can be flushed down toilets safely.

Manufacturers of wipes will be able to feature an official water industry ‘Fine to Flush’ symbol on their packaging if they pass strict scientific tests. This symbol will let consumers know that the products don’t contain plastic and will break down in the sewer system instead of clogging up sewers and contributing to fatbergs which cause blockages and sewage overflows.

In 2017 the biggest ever in-depth investigation of sewer blockages in the UK proved that wipes being flushed down toilets caused serious problems in the sewerage system. The project found that non-flushable wet wipes could make up around 93% of the material causing some sewer blockages. These wipes – which included a high proportion of baby wipes – are not designed to be flushed.

The technical name for ‘Fine to Flush’ is Water Industry Specification 4-02-06, and the full details of the specification can be found on the Water UK website. Manufacturers can contact WRc to find out more about the process for having their wipes tested and receiving the official ‘Fine to Flush’ symbol.
