Abstract

Disclosed herein is a method for purging water in a waterpark reservoir by inducing a siphon and several examples of an apparatus to achieve this result. The apparatus disclosed herein provides an emptying mechanism which may have no moving parts or valves between the inlet and the outlet and yet delivers a short term large volume dump or purge of water to patrons in an impact area of a patron region of a waterpark.

Claims

1. A water dump apparatus for a water park feature in a water park, the apparatus comprising:

an upper reservoir configured to retain a volume of water therein;

the upper reservoir having a lower interior surface, an upper edge, and a surrounding sidewall;

a fluid inlet through which is provided a flow of water into the upper reservoir;

a lift conduit in fluid communication with the upper reservoir, the lift conduit having a lower edge above the lower surface of the upper reservoir, and an upper edge below the upper edge of the upper reservoir;

a drain conduit sealed to the lift conduit and having an upper edge below the upper edge of the lift conduit and a lower edge below the lower edge of the lift conduit;

an outflow in fluid communication with the lower edge of the drain conduit, the outflow configured to periodically outflow water from the water dump apparatus.

2. The water dump apparatus as recited in claim 1 further comprising a lower reservoir vertically below the upper reservoir, the lower reservoir in fluid communication between the drain conduit and the outflow.

3. The water dump apparatus as recited in claim 2 further comprising a plurality of surfaces defining outlets through sidewalls of the lower reservoir.

4. The water dump apparatus as recited in claim 3 wherein the outlet has a lower edge vertically above the lower edge of the drain conduit such that a volume of water is retained between the lower edge vertically and the lower edge of the drain conduit forming a headspace in the lower reservoir configured to produce a headspace in the upper reservoir above the upper edge of the drain conduit.

5. The water dump apparatus as recited in claim 1 further comprising a vent conduit having an upper end in fluid communication with an upper region of the lift conduit, and a lower end positioned above the lower edge of the lift conduit.

7. The water dump apparatus as recited in claim 1 further comprising a seasonal drain provided in the lower reservoir configured to continuously allow passage of water there through and drain the lower reservoir when the water pump is not actuated.

6. The water dump apparatus as recited in claim 6 wherein the length of the vent conduit between the upper end and the lower end is adjustable.
