I have worked has a Diver Inspecting water tanks since 1992. It must be nasty down under Dusty McWilliams assumes that all the tanks in the world are as filthy has his. In fact here in Texas we have many facilities that dont need to be cleaned even after 10 years of service. It is true you need commercialy trained divers who have been trained to work in a confined space. My Company offers Video and photos to show you the condition of your tanks inside and out, No Draining the tank, No water loss, No Problem Ron Perrin ronlooka@aol.com
