Weekly Watering Schedule

Drought is Here: It's Time to Conserve 

With reservoirs at historic lows, Marin Water's board of directors adopted new mandatory water use restrictions to help preserve our water supply. The goal of the mandatory restrictions is to achieve a 40 percent reduction in overall water use districtwide.

The biggest water savings can be found outdoors. We are asking all of our customers to turn off or, at least, significantly reduce irrigation by applying the minimum amount of water to maintain plant health.

The irrigation run times in the Weekly Watering Schedule have been reduced by approximately 50 percent for the drought emergency. Irrigating at this level should be sufficient to maintain plant health. Monitor plants closely for signs of drought stress.

How To Use The Weekly Watering Schedule

Detailed information is provided in the Weekly Watering Schedule User Guide.

  1. Select your plant type.
  2. Select your irrigation type.
  3. Look up the run times for the climate zone where you're located. 
  4. The weekly run time is often split into multiple, shorter run times to help reduce runoff. Allow 30 to 60 minutes between run times to allow water to soak into the soil.
