One of the best schematic you can find, in my opinion, is WEDC F-diagram: it is simple and visualize the transmission route of faecal-oral diseases, along with the barriers and type of interventions to prevent their transmission.

It does not cover all water borne disease, but it's a good start. WEDC also offers a free library on WASH, where you may find other posters of the kind.
