Five ways to cut irrigation water use by up to 40%

Practical actions to reduce residential irrigation consumption: scheduling, sensors, ET-based control, mulching and hydrozones.

Watering schedule matters

Watering at dawn reduces evaporation compared with midday runs and improves irrigation efficiency immediately.

Use rain and soil-moisture sensors

Sensors stop unnecessary runs after rain or when soil is still wet, reducing avoidable water waste.

ET-based controllers

Smart controllers can adapt run times to weather-driven evapotranspiration instead of fixed schedules.

Mulch to reduce surface evaporation

A mulch layer helps retain soil moisture, lowers peak temperatures and reduces irrigation frequency for beds.

Hydrozone design

Grouping plants with similar water needs into separate zones avoids overwatering drought-tolerant plants.
