You forgot to mention the wall reinforcements. Are they centered or placed at the edge? Are these basement walls? If they are, there is no additional load for the wall because the most critical case is when the water is empty. You have to check the foundation though because of the added weight of water.

I have a client who is refurbishing his 4-storey apartment building.
The superstructure loads are transmitted to the foundations via 8-inch
thick loadbearing reinforced blockwalls. The Client wants to convert an
unoccupied underground compartment under the apartments into a rainwater
storage tank (a town planning requirement), as there are financial and
space constraints. There is currently no floor slab in this
compartment. This compartment is 22ft long by 16ft wide and 6ft high.
The compartment comprises four 8-inch thick reinforced concrete block
loadbearing walls. These walls are supported by 2ft and 3ft wide
reinforced concrete strip footings on sandy/gravel soil. The water
table is within two feet of the footings.
Could anyone on the list suggest possible methods of solving this
problem? I am concerned about making the compartment as watertight as
possible (new slab and existing foundation joint) and making sure that
the walls can resist the hydrostatic pressure imposed by the stored water.
