Demount spray bowser ideas

[Wobblebox]

I’ve a 26ft flatbed bale trailer here that could be utilised as a base for a demount spray bowser, Would like it to have a 7000 litre water tank, chem storage lockers and a pump capable of filling tank in 30-45 mins, would a hydraulic pump be cost effective?
Would need to be easily removed and no major mods on trailer as still required for bale moving.
Anyone got any ideas, pics, designs on how to do one?

@Clive mounted a tank on a low loader for a similar project.
