Large Deep potable water service Reservoirs
(OP)
I am looking at options for large covered potable water storage reservoir. Apart from the standard rectangular RC and circular pre stressed options, I am considering the possibility of secant pile or diaphragme walls. I am searching for examples of where they may have been used before.

If you're looking for other options, I'm afraid I can't help you. There are basically only a few types of materials (steel, concrete, prestressed concrete) and shapes (round, not round) so it's unlikely you're going to stumble on a concept that's much more efficient than the basics. There's a reason that they're most common.

However, you are still required to contruct the tank bottom above the 100 year flood or protect it from the 100 year flood.

There are also good reasons to construct the tank above the ground water elevation as well.

Maybe we bury the roof under 2 or 3 feet of fill (difficulty then is ensuring fill depths do not exceed design depths - i.e some future well meaning operations/maintenance personnel do not heap fill onto one or two panels).
Going back to my original question I see no difficulty in using a secant pile wall technique for the perimeter reservoir wall, a hopper shaped bottom or a stepped bottom and sticking some pumps in a caisson in the centre of the reservoir to get the water out.
