Abstract
A land drainage apparatus, system, and method utilize a vacuum pump and atmospheric pressure to lift water from a collection basin to a level above a fluid intake level. After a certain amount of water is lifted and collected in a second chamber above the level of the collection basin, the vacuum can be broken, enabling the water to flow out of the second chamber by gravity flow to an exit, wherein the exit is above the fluid level intake and below the second chamber.
Claims21
A method of draining a land area of excess water, comprising the steps of:
- a) providing a catch basin for collecting fluid to be drained;
- b) providing a vacuum chamber having a chamber interior, the vacuum chamber positioned at a level above the catch basin and in fluid communication with the catch basin;
- c) subjecting the vacuum chamber interior to a vacuum to pull air out of the vacuum chamber and lift water from the catch basin into the vacuum chamber;
- and
- d) breaking the vacuum and allowing water to drain from the vacuum chamber to an exit, wherein the exit is above a fluid level intake of the catch basin and below the vacuum chamber.

A land drainage system comprising:
- a) a primary catch basin for collecting fluid to be drained;
- b) fluid collected in the primary catch basin having an inlet fluid level;
- c) a vacuum chamber having a vacuum chamber elevation;
- d) an exit having an exit elevation that is higher than the fluid inlet level at the primary catch basin;
- e) a flow line operable to allow fluid flow from the primary catch basin to the vacuum chamber;
- f) an exit line operable to allow fluid flow from the vacuum chamber to the exit;
- g) wherein the inlet fluid level is below the vacuum chamber elevation, and wherein the exit elevation is located between the inlet fluid level and the vacuum chamber elevation;
- h) a vacuum pump or a regenerative blower operable to pull a vacuum on the vacuum chamber which causes fluid collected in the primary catch basin to lift and flow to the vacuum chamber and/or into the exit line;
- and
- i) a valve having a valving member movable between an open position and a closed position, wherein the valve in the closed position causes creation of a vacuum in the system wherein a vacuum is pulled on the vacuum chamber and wherein the valve in the open position enables air flow in the system which breaks the vacuum, enabling water collected in the vacuum chamber to drain to the exit line and out the exit via gravity;
- and
- wherein creating the vacuum and then breaking the vacuum enables the system to lift the fluid above the inlet fluid level and to drain the fluid without also having to use a standard pump or a fluid pump that requires fluid to pass through the pump.

A method of draining a land area of excess water, comprising the steps of:
- a) providing a catch basin for collecting fluid to be drained;
- b) providing a vacuum chamber having a chamber interior, the vacuum chamber positioned at a level above the catch basin and in fluid communication with the catch basin via attached tubing;
- c) creating a vacuum in the vacuum chamber and attached tubing which causes atmospheric pressure to push the fluid up into the vacuum chamber;
- and
- d) breaking the vacuum to allow gravity draining of fluid from the vacuum chamber to an exit, wherein the exit is above a fluid level intake of the catch basin and below the vacuum chamber.
