Help Needed with Water Tank

We have a couple of the 300 water storage containers behind our cabin. We need help first to be able to access the water via a hose arrangement, and second, need to construct a filtering system. We got some advice from Graeme Shelford as to a design for the filtering system - but will need help constructing it.
In addition to the water storage tanks behind the cabin - we have another water storage tank that needs to be placed and hooked up to our roof drainage system of the cottage further down our lane.
