====Build the roof of the tank====

# Cut the wood boards so that one edge is curved outward. This can be done while the tank walls are curing. The tank size will dictate the necessary sizes of the forms.

# Once the walls are fully cured, position the wood beams inside the tank. One log will be the center pole sticking up vertically from the center of the foundation. Two logs will be cross bars near to the top of the walls to support the wooden roof forms. Additional vertical logs will also be used to support the wooden roof forms; these logs should be placed along the inside circumference of the walls.
