The system includes a water reclamation tank that stores water captured from beneath the area of land. When it is time to water the area of land, the sprinkler system draws water from the water reclamation tank. A portion of this water is then recaptured and supplied back to the water reclamation tank for further storage until the next time the sprinkler system is activated. This cyclical process occurs repeatedly and enables a significant reduction in the amount of freshly supplied water used to maintain the area of land. ## Claims ### Claim at position 1 1-21. (canceled) ### Claim 22 A method for reducing water usage, the method comprising: receiving a first volume of water at a water tank from a water drainage system that includes a funnel located under an area of land; receiving an electronic irrigation signal from a sprinkler management system; and in response to the irrigation signal, automatically generating a pump signal to activate pumping a second volume of water from the water tank to a water distribution apparatus to irrigate the area of land above the funnel. ### Claim 23 (depends on 22) The method of claim 22, wherein the water drainage system includes a plurality of funnels, and the first volume of water is received based on water flow through one or more of the funnels. ### Claim 24 (depends on 23) The method of claim 23, wherein the water distribution apparatus includes a water flow path provided between at least two of the plurality of funnels. ### Claim 25 (depends on 22) The method of claim 22, further comprising applying an additive to at least one of the first or second volumes of water. ### Claim 26 A method for reducing water usage, the method comprising: receiving a first volume of water at a water tank from a water drainage system that includes a funnel located under an area of land; receiving an electronic water level signal from a first sensor, the electronic water level signal representative of a sensed volume of water in the water tank; and based at least in part on the sensed volume of water, automatically generating a fill signal to activate adding water to the water tank from a source other than the water drainage system. ### Claim 27 A method for reducing water usage, the method comprising: receiving a first volume of water at a water tank from a water drainage system that includes a funnel located under an area of land; receiving an electronic water level signal from a first sensor, the electronic water level signal representative of a sensed volume of water in the water tank; and based at least in part on the sensed volume of water, automatically generating a pump signal to activate pumping of water from the water tank to a water distribution apparatus to irrigate the area of land above the funnel. ### Claim 28 (depends on 27) The method of claim 27, further comprising: receiving an electronic flow signal from a second sensor, the electronic flow signal representative of a sensed level of water flow through a water flow path in the water drainage system; and based at least in part on the sensed level of water flow, automatically generating a stop signal to deactivate the pumping of the water. ### Claim 29 A method for reducing water usage, the method comprising: receiving a first volume of water at a water tank from a water drainage system that includes a funnel located under an area of land; receiving an electronic moisture signal from a first sensor, the electronic moisture signal representative of a sensed level of moisture of the area of land; based at least in part on the sensed level of moisture, automatically generating a pump signal to activate pumping of water from the water tank to a water distribution apparatus to irrigate the area of land above the funnel. ### Claim 30 (depends on 29) The method of claim 29, further comprising: receiving an electronic flow signal from a second sensor, the electronic flow signal representative of a sensed level of water flow through a water flow path in the water drainage system; and based at least in part on the sensed level of water flow, automatically generating a stop signal to deactivate the pumping of the water. ### Claim at position 11 31-36.
