The present invention provides numerous methods, systems and apparatus that use a novel form of water budgeting technology for water conservation without the use of complex ET (Evapotranspiration) data or methods. Embodiments include incorporating the technology directly into irrigation controllers, into modules added on to existing controllers, or into central units that broadcast a water budget that can alter the schedules of one, many, or selected groups of remotely located controllers or modules. The various methods of the present invention offer the choice of adjusting the station run times, accumulating the water budgets, altering the watering intervals, and/or combining the present water budgeting technology with local watering communities' restricted watering schedules. The result offers residential, commercial, and municipal users a wide range of practical choices for effective water conservation in landscape irrigation with temperature based water budgeting.
