Abstract: An above ground liquid storage system includes a substantially impermeable liner bounding an interior for receiving a liquid. A plurality of supporting structures and a base support the liner and the liquid when the liquid is received in the interior. The liner extends from the base over a top end of the plurality of supporting structures and descends to the ground to form a cavity under the plurality of supporting structures. A first supporting structure of the plurality of supporting structures includes a leg member supporting the liner and a support member connected to the leg member and holding the leg member upright. At least one of the leg member and the support member includes a releasably attachable extension portion to allow separation of the extension portion from a remainder of at least of the leg member and support member.

A plurality of supporting structures and a base support the liner and the liquid when the liquid is received in the interior. The liner extends from the base over a top end of the plurality of supporting structures and descends to the ground to form a cavity under the plurality of supporting structures. A temperature controller in communication with the cavity controls a temperature of the cavity to control the temperature of liquid in the interior.
