UVI System and similar

Very interested in setting up here in Thailand something along the lines of the UVI system. Plenty of info available on line about this system and sizing etc. Indeed the guys at UVi have been very helpful in all this posts and papers etc. Lots of open info.

Does anyone know of a system similar to the UVi which is up and running commercially ? Would be useful to touch base before I start digging up my backyard for sumps etc:)
