A liquid containment barrier is formed by corrugated panels connected
end to end and supported by upstanding brackets at spaced positions around the

peripheral wall and a liner attached to the wall. Each panel has the top edge
as a
raw edge with a plurality of elongate extruded plastics spring channel members

engaged over the top edge. A plurality of additional clamp collars are
arranged to
surround a part cylindrical portion of the channel members to bridge between
panels
and to forma local clamping force on the channel member. Each bracket has an
inner vertical edge engaging the panels and a rod member hooked to the brace
at
the lower end and engaging over the channel members at the upper end. The
bracket also includes an upwardly extending flange parallel to the inner edge
to form
a channel for the bottom edge of the panel.

corrugated curved panels bolted edge to edge with a liner extending over the
cylindrical wall and support surface to contain the water within the tank. An
access
opening is formed in one panel of the cylindrical wall and includes a frame
with a
rectangular planar front flange and a rearwardly extending flange welded into
the
hole. Liner retention straps surround the hole to fasten an edge of the liner
around
the hole. An access cover plate is bolted to the front flange of the frame and
carries
a hoop strength plate which fastens to studs at the rear of the plane so that
the
plates are removable to allow service access to the interior of the tank.
