Irvine Ranch Water District (IRWD) Watering Information

What Time of Day Should I Water?

In the IRWD service area, we recommend watering between 5 p.m. and 9 a.m. Watering within this window of time takes advantage of relatively low winds and less loss of water to evaporation.

How Long Should I Water?

Precise watering times vary depending on the type of watering device, soil, slope and plants. Keep in mind with clay soils, running an irrigation system on a lawn for more than five minutes will generally result in runoff.

How Often Should I Water?

SUMMER NO MORE THAN 2 TIMES PER WEEK	FALL NO MORE THAN 1-2 TIMES PER WEEK
SPRING NO MORE THAN 1-2 TIMES PER WEEK	WINTER USUALLY NOT NEEDED
