Irrigation water recirculation system
An irrigation recirculation system and methods of filtering and cleaning water within the irrigation recirculation system. The system includes an above the ground water source and a fluid flow conduit that conveys the water into a filter element within a basin. The filter element separates solids from the water by causing the water to change direction before continuing on a fluid flow path. The water is then stored and distributed by a self-cleaning storage system that convey the filtered water to sprinkler heads of the irrigation system.
1. A method of filtering recirculated water for an irrigation system comprising:
collecting water from an above the ground source;
separating solids from the water by changing a direction of a flow of the water with a filter;
after separating the solids from the water, conveying the water to a discharge nozzle of an irrigation system;
after separating the solids from the water, conveying the water to an underground storage tank;
conveying ground water adjacent the underground storage tank through a perforated membrane of the underground storage tank and into the underground storage tank;
inhibiting or preventing additional solids from entering the underground storage tank via the adjacent ground water with the perforated membrane.
2. The method of claim 1 , further comprising:
after separating the solids from the water, conveying the water to a distribution tank;
pumping water within the distribution tank with a waste water pump to a waste water reservoir;
while pumping water within the distribution tank with the waste water pump, moving the water in the distribution tank by pumping water within the distribution tank with a sprinkler head pump to convey the water to the discharge nozzle.
3. The method of claim 2 wherein the sprinkler head pump creates greater water pressure than the waste water pump.
4. The method of claim 1 , further comprising:
after separating the solids from the water; conveying water through a microfilter prior to conveyance to the discharge nozzle.
5. The method of claim 1 wherein changing the direction of the water with a filter comprises:
conveying water within a fluid flow conduit above a threshold velocity along a fluid flow path; and
striking a vertical filter element positioned perpendicular to the fluid flow path within a basin.
