David Pagan Butler explains how a DIY pool in Georgia, USA was made - zero build, with only sculpted earth walls and his bubble flow circulation system. This pool was made by Alan Hall with the help of his family and friends (and moral support from David) and is an inspiration for those who aspire to create a beautiful, chemical free pool for swimming and a precious habitat for wildlife.
Have a look at Alan's moving film of the project:
