                        * The rock component provides additional storage and it's porosity
                           (typically 40%) is used when calculating the tanks overall storage
                           capacity.
                        * The ecoAID® system can be installed in a single or double layer
                           configuration.
                        * Please refer to our ecoAID® standard detail drawings for more
