We, like a lot of allotment sites, have to use water tanks to fill our
watering cans. Someone on our site is using the tank near us as somewhere
to wash off soil from tools, produce and hands such that I dug out a thick
layer of mud from the bottom of the tank. My understanding is that if that
person has some soil born diseases on their plot (White Rot. Club Root)
they will spread it around the site by doing such things.
But am I right in that thinking?

Correct.

Using fresh (mains or rain) tanked water for activities other than
irrigation should be considered for final treatment
as foul water.

Fraid I am not even a fan of using ex-bathing or personal washing water for
plant watering either.
Best directed in to the sceptical tank with other humane detritus --- imho
