Well im going to get a trolley!? shock horror!  

 I graft hard for 8 hours in a day.
 If i was to clean for 8 hours with wfp doing tops and hard to reach areas using a regulator and nozzles that help with water usage how many ltrs do you think i would use.
 I can knock out 4-5 average sized detatched houses using trad methods so at least would have to do the same.
 Just trying to work out whether i should just pile the van up with containers of pure water or get a van mount tank to get water from.
 Swings and roundabouts cos if i fill up containers then its done whilst at work but a tank is easier to fill at night and can hold loadsa water.
 How much do you guys use? If you dont work 8 hrs how much would you use? 
 I still want to work the same hours and cant get home easilly for water.
 Cheers guys.
