Drought Calendar - Updated June 15, 2017 

In April 2017, the Governor declared that California is officially out of the drought. The Governor stated that despite our current water situation, water conservation must be a way of life for all Californians and many water conservation measures remain permanent. 
This includes prohibitions against the following actions: hosing off sidewalks, driveways and other hardscapes; washing cars with hoses not equipped with a shut-off nozzle; using non-recirculating water in a fountain or other decorative water feature; watering landscape that causes runoff or is within 48 hours of measureable precipitation; and irrigating ornamental turf on public street medians.

Potential Water Reduction Measures 

Water Saving Measures.

1. Contact your water company to learn about different ways to reduce water use.

2. Adjust your sprinkler heads so they are directed only on your lawn and garden and avoid wetting sidewalks and patios.

3. Use mulch or ground cover.

4. Choose drought tolerant and/or native plants whenever possible; go to for more information on native plants. San Carlos is in Climate Zones 9 and 10. Select Mediterranean climate and California native plants that are adapted to our climate of seasonal rainfall. Consider plants that offer food for wildlife and enhance local habitat. Also, avoid invasive species to prevent the further spread of exotic plants. Sunset Magazine also has a number of articles on drought-tolerant landscaping at

5. Consider replacing your lawn. Cal Water sometimes offers a Turf Replacement Rebate Program available at The Bay Area Water Supply and Conservation Agency (BAWSCA) Lawn Be Gone! Program provides rebates to approved customers that convert water-thirsty lawns to water-efficient landscapes. Go to to learn more. Currently, Cal Water customers in San Carlos are eligible for these rebates as long as they are offered.

6. Rather than washing your car at home, consider taking it to a car wash that recycles the water.

Develop water-wise habits.

1.  Run only full loads in the dishwasher and use shorter wash cycles. Your machine uses the same amount of water whether it is full or almost empty.

2.  Wash only full loads in the washing machine, use cold-water settings and shorter cycles. One load of laundry typically uses 40-50 gallons of water.

3.  Fix leaky toilets. A running toilet can waste many gallons per minute; often a faulty flapper is the culprit. See
Cal Water rebates for water efficient toilets.

4.  Turn off the water while you brush your teeth. Up to 2 gallons of water are used, if the tap is left on!

5.  Shorten your showers by two minutes.
