Well as I am putting a filter in or allowing room, I am trying to find a case study with filters am finding it hard as they are massive filters, Manly just put them inside the signs around and not in the fountain itself in this pdf file it explains a lot about the success of the fountain, and that its cleaned twice a day.
Culligan Water has a Community Grants program that can give your council, school or community facility FREE water filter equipment for every water fountain that you install or upgrade in your community. In addition to this, Culligan Water is willing to provide replacement water filters at half price.
Each filter provides 10,000 litres of filtered drinking water – this equates to an approximate cost of only $60 per bubbler per quarter. This half price offer covers the entire life of your water fountain.
