Abstract
Abstract This invention relates to an underwater storage tank for the temporary storage of liquids such as overflow storm water. The tank consists of top and bottom walls with at least the top wall being a flexible and collapsible membrane made of rubber or similar material and a metal framework of piping to which the membranes are secured. The structure is placed in position on the bottom of a lake, for example, and is connected, by means of an inlet-outlet pipe, to a sewer system. The pipes of the metal framework include jets which are connected to a source of liquid under pressure which can be used for flushing the tank. The tank also includes a cover for the inlet-outlet pipe which assists in disbursing large pieces of sediment and also assists in removing the same from the tank. The tank also includes vent valves for the escape of gases which may evolve while the sewage is in the tank and furthermore includes means for determining the volume of the tank at any given time.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
169 words
In combination with a source of liquid supply a substantially collapsible underwater storage system, comprising: a. a hollow frame adapted to be anchored on the bottom of the body of water in which said system is placed; b. a substantially closed tank body 1. of fluid impermeable material 2. secured to said frame; c. a conduit adapted to interconnect the interior of said body with said source of liquid supply 1. whereby said liquid can be passed into and out of the interior of said body; d. sediment control means 1. disposed within said body adjacent the point of connection of said condUit means with said body and 2. adapted to facilitate sediment removal from said body; e. vent means 1. carried by said body and 2. adapted to automatically permit the escape of gases accumulated within said body; f. measuring means mounted on said body and adapted to measure the volume of liquid within said tank; and g. flushing means adapted to flush the interior of said tank.
Claim 2
Dependent Claim
