Man's DIY Natural Swimming Pool Makes Waves Across The Globe

Filmmaker David Pagan Butler, created his own eco-friendly pool in his back garden and is now teaching others to do the same. Mr Butler created a step-by-step self-build video which has been viewed more than five million times on YouTube. The father-of-four said: "I've always been interested in swimming in wild water, free from chemicals, because afterwards you feel so much better than if you had swam in a conventional pool." Mr Butler's DIY video and manual have been used by natural pool enthusiasts in far flung places like America, Brazil, Mongolia, Australia, France, Russia, Thailand and many other countries.
