Abstract
This invention relates to a liquid storage system for storing liquid products, particularly petroleum and its derivatives. An auxiliary dam (,) within a bund defined by a main dam (,) bounds an area (,) around a tank (,) in such a way that the contaminating wastes from the fluids stored in the tank are contained within that area (,). This arrangement reduces the volume of contaminated rainwater within the bund, consequently reducing the costs of water treatment for subsequent discharge to the stormwater drain system
