Hi Petros, these were built by TAYMECH who seemed to be part of Taylor Woodrow construction. I have a brochure which states they had a 500 gallon foam tank but no mention of water, so maybe a pre-mix of some sort.

Thanks Bob you are a star! Seems they mainly built refuellers. You can even buy a model
