The present invention is directed to an intelligent water management irrigation system for monitoring the total water usage for a billing site and preventing cumulative water usage from exceeding a water budget by adjusting the amount of water used for irrigation. Irrigation zone priority values are selected for each irrigation zone that specify a percentage of the full water need that the foliage in the zone can survive and are saved in an intelligent water management irrigation (IWMI) controller. The IWMI controller receives water usage information originating from a property's water meter and compares the measured water usage with the allowable water budget. Water usage is tracked separately for the household use and landscape use (irrigation). Prior to each irrigation cycle, the IWMI controller estimates the amount of water that will be needed by the landscape and for household use during the remainder of a billing cycle; household use is given precedence over landscape use. If the water budget will support both, irrigation can proceed normally. If the budget will not support both, the IWMI controller estimates the amount of water needed for the remainder of the billing cycle if only a priority watering amount is allocated for each landscape zone. If the water budget will support priority irrigation, landscape watering can proceed in priority irrigation mode. If the water budget will not support priority irrigation watering, the irrigation cycle is skipped and the water usage estimations are recalculated prior to the next irrigation cycle.

The present invention is directed to an irrigation controller, method and software program product for generating valve control signals for energizing a valve. The irrigation controller includes a valve actuation control module selectively coupled each of plurality of control nodes and generating a valve actuation control signal thereon. The valve actuation control signal is a continuous control voltage over a plurality of control signal periods for selectively energizing the selected irrigation valve. Also integrated in the irrigation is a valve chatter module for selectively coupled each of plurality of control nodes and generating a valve chatter control signal thereon. The valve chatter module selectively and, intermittently, energizes the selected irrigation valve. The irrigation controller may further include a remote controller of remotely controlling the irrigation controller.
