It's my opinion that when the general public get to understand or here about the large amounts of "Waste" water that is produced, during the purifying stage...
God help anyone who try's to use WFP ONLY during a DROUGHT!
I will use any style wfp, trad, hey I'll even use windowlean if they ban the bucket!
(but just to clarify I am not using ladders again, i'll buy one of those wagtail/poles before I do that!)
