According to the sewage experts providing an analysis of the Whitechapel
fatberg in London, yes, wet wipes and such are a big part of the problem¹. Wet wipes and other comparable sanitary products
combine with the fat in the sewers to create these blockages — massive ones in areas with ageing sewer pipes and a lot of people.
Solving this problem means reducing both fat and sanitary products that should not be flushed.
One proposed action in London is to stimulate toilet owners to place bins next to the men's toilets as well. A sizeable group of men using wet wipes is a recent phenomenon, providing a place to dispose of them might help.
And honestly, what makes people flush nappies, period products, and condoms down the toilet? Awareness (clear 'don't flush' messages on packaging perhaps?) can be part of the solution too.
