A system and method for harvested water irrigation is provided. The irrigation system generally collects harvested water from a variety of sources and disperses it from a tank to a landscape for irrigation. The irrigation may be managed using a system controller. The system controller interacts with a variety of devices, including a level controller, a pump or valve, and at least one zone valve. The system may be configured to end irrigation cycles in response to certain events and to supplement harvested water irrigation with potable water as needed or selected.

1. A method for irrigating comprising: providing an amount of harvested water to a tank from at least one source;determining when the amount of harvested water reaches a first predetermined amount;starting an irrigation cycle when the amount of harvested water reaches the first predetermined amount

1. A method for irrigating comprising: providing an amount of harvested water to a tank from at least one source;determining when the amount of harvested water reaches a first predetermined amount;starting an irrigation cycle when the amount of harvested water reaches the first predetermined amount by delivering the harvested water to at least one zone;determining when the amount of harvested water reaches a second predetermined amount; andstopping the irrigation cycle to at least one zone when the amount of harvested water reaches the second predetermined amount. 2. The method of claim 1 further comprising: determining a moisture balance corresponding to at least one zone;when the moisture balance of at least one zone reaches a maximum field capacity, stopping the irrigation cycle in that zone. 3. The method of claim 2 further comprising: determining when the amount of harvested water in the tank reaches a disposal amount;determining whether one or more zones are not at a maximum field capacity;starting a disposal irrigation cycle to the one or more zones not at a maximum field capacity; andstopping the disposal irrigation cycle when a disposal ending event occurs,wherein the disposal ending event is selected from the group consisting of the amount of harvested water reaches a pre-established level; a predetermined amount of watering time has elapsed; and all zones reach their maximum field capacity. 4. The method of claim 1 further comprising determining the moisture balance of at least one zone before starting the irrigation cycle. 5. The method of claim 4 wherein if the moisture balance of one or more zones is already at the maximum field capacity, then such one or more zones will not be irrigated. 6. A method for use in irrigation control comprising: providing an amount of harvested water to a tank from at least one source;determining when the amount of harvested water reaches a first predetermined amount;starting an irrigation cycle when the amount of harvested water reaches the first predetermined amount by delivering the harvested water to at least one zone;determining a moisture balance corresponding to at least one zone;when the moisture balance of a particular zone of at least one zone reaches a maximum field capacity, stopping the irrigation cycle in that particular zone;determining when the amount of harvested water reaches a second predetermined amount;stopping the irrigation cycle when the amount of harvested water reaches the second predetermined amount; andstarting an irrigation cycle in at least one zone using a potable water source if the moisture balance before irrigation of at least one zone falls to a critical deficit level before the amount of harvested water reaches the first predetermined amount. 7. The method of claim 6 further comprising stopping the irrigation cycle using the potable water source when the moisture balance of the at least one zone being irrigated using potable water rises above the critical level. 8. The method of claim 7 further comprising: starting a harvested water irrigation cycle using harvested water when the amount of harvested water reaches the first predetermined amount; andstopping the harvested water irrigation cycle when an ending event occurs. 9. The method of claim 8 wherein the ending event is first to occur of the amount of harvested water reaches the second predetermined amount, the moisture balance of a zone reaches the maximum field capacity, and an amount of rainfall reaches a saturation threshold. 10. The method of claim 9 wherein the saturation threshold is detected by a rainfall sensor or a soil moisture sensor. 11. The method of claim 4 wherein if the moisture balance before the irrigation cycle of at least one zone falls below a critical deficit level before the amount of harvested water reaches the first predetermined amount, the harvested water in the tank is supplemented with potable water until the first predetermined amount is reached. 12. The method of claim 1 wherein the irrigation cycle is delayed until a scheduled watering. 13. The method of claim 12 further comprising: monitoring a moisture balance of at least one zone before the irrigation cycle;determining if the moisture balance of a zone falls to critical deficit level before the scheduled watering; andirrigating the zone until the moisture balance rises above the critical deficit level. 14. The method of claim 8 wherein the harvested water irrigation cycle is delayed until a scheduled watering. 15. The method of claim 1 wherein irrigation is via emission devices selected from the group consisting of spray heads, rotors, drip components and impact drive sprinklers. 16. The method of claim 1 wherein when an amount of rainfall reaches a saturation threshold, all irrigation stops if in progress and will not start if not in progress. 17. The method of claim 1 further comprising determining the irrigation cycle timing and duration based upon at least one variable. 18. The method of claim 17 wherein the at least one variable is selected from the group consisting of a watering schedule, an evapotranspiration (ET) value, a moisture balance of at least one zone, and a saturation threshold of rainfall. 19. The method of claim 18 further comprising determining an amount of time remaining in the watering schedule when the amount of harvested water reaches the second predetermined amount. 20. The method of claim 19 wherein the amount of time remaining is finished during, or added to, a subsequent irrigation cycle.
