Abstract:
1. A method for intelligent irrigation water management implemented by an irrigation controller for a site comprising: registering cumulative water use information for water used at a site from a single metering device, said site having a plurality of irrigation zones and said cumulative water use comprises irrigation water usage and non-irrigation water usage data; receiving first cumulative water use information at an irrigation controller for cumulative water used at the site over a first time period; receiving second cumulative water use information at the irrigation controller for cumulative water used at the site over an irrigation time period, wherein the irrigation time period is within the first time period; finding a first non-irrigation water use quantity for the first time period by reducing the first cumulative water use by the second cumulative water use; forecasting a second non-irrigation use water quantity for a second time period; calculating an irrigation cycle water quantity for a subsequent irrigation cycle in the second time period, said irrigation cycle water quantity comprises a plurality of water zone quantities, each of the plurality of water zone quantities is associated with an irrigation zone of the plurality of irrigation zones; finding a reduced irrigation cycle water quantity for the subsequent irrigation cycle based on the forecast of the second non-irrigation use water quantity; and executing the subsequent irrigation cycle at the reduced irrigation cycle water quantity.
