Water Conservation Tips
How to Save Water Inside and Outside of Your Home

Fresh water is already a finite resource in California so when a drought strikes it’s even more important to reduce water use where and when possible. 

On Oct. 1, 2016, California officially entered into its sixth year of drought after ending its fifth straight year of dry conditions.

The effort to save water in the state was heightened in 2015 in the fourth-straight year of drought and as the state experienced its lowest snowpack ever recorded. On April 1, 2015, Gov. Jerry Brown ordered first-ever, statewide water reductions.

The mandatory reductions were suspended in May of 2016 following a successful year of water savings in which Californians cut their urban water use by 24 percent compared to 2013.

Still, on May 9, Gov. Brown issued a new executive order calling for permanent water use efficiency and asking that Californians make water conservation a way of life. Most communities then set their own conservation standards based on a three-year “stress test” projection.

With this in mind, there are several ways to conserve water at your home by fixing leaks in faucets and toilets, and reducing shower times. Outside water use presents a huge opportunity for savings since it can account for anywhere from 50 percent of a home’s total water use in the cooler areas to 80 percent in the hotter, desert regions.

Outdoor Tips

When to water

  • During the cooler parts of the day. Do not water between 10 a.m. and 6 p.m., otherwise some of the water will be lost to evaporation. Early morning is better than dusk; watering at dusk can lead to growth of fungus. Save 25 gallons of water.
  • Adjust or deactivate automatic sprinklers on cool, overcast days, and when it’s raining. Turn them back on only when needed.
  • Avoiding watering on windy days as it can push the water to the sidewalks and too much of it can be lost to evaporation..

Sprinkler systems

  • Adjust your sprinkler heads so that the water lands on the lawn or garden where it belongs: and not on the sidewalk or street. Save 15 gallons each watering time.
  • Water your landscape in cycles by reducing the number of minutes on your timer and using multiple start times spaced one hour apart. This allows the water to soak into the soil and avoids wasting the water to runoff.
  • Visually inspect your sprinkler system once a month during daylight hours to make sure there are no leaks and that it is spraying the area correctly.

Other Irrigation Tips

  • Install a weather-based, smart sprinkler system with an automatic rain shutoff device.
  • Use greywater for irrigation and plants. Save 40 gallons per day.
  • Aerate your lawn by punching small holes in it about six inches apart. This will allow water to penetrate to the roots and lessen runoff.
  • Install drip irrigation systems where possible so water goes to the root of a plant. Save 15 gallons.
  • Use rainwater recapture for plant and irrigation needs. Save 934 gallons per 1 inch of rain on a 1,500-square-foot house.

What to plant

  • Native grasses, succulents and other drought-tolerant plants such as lavender, sage, rosemary or lantana that use less water than many plants.
  • Use native plants in your garden that are by nature drought-tolerant. Check out a list of native plants by region from the California Native Plants Society. Save 30-60 gallons per 1,000 square foot.
  • Use this chart from PlantRight to help find native Californian alternatives to invasive plant species.
  • Search for low water-use plants using this database available on the University of California Division of Agriculture and Natural Resources.
  • Place a layer of mulch around trees and plants to slow down evaporation. Save 20-30 gallons per 1,000 square foot.
  • Add compost or an organic matter to soil as necessary, to improve soil conditions and water retention.

Lawn Care

  • When mowing your lawn, set the mower blades to 2-3 inches high. Longer grass shades the soil, improving moisture retention, and has more leaf surface to take in sunlight, allowing it to grow thicker and develop a deeper root system. This helps grass survive drought, tolerate insect damage and fend off disease.
  • Leave lawn clippings on your grass, this cools the ground and holds in moisture.
  • Let your lawn go dormant (brown) during the winter. Dormant grass only needs to be watered every three to four weeks, less if it rains.

Cars/Driveways

  • Don’t run the hose when washing your car. Use a spray stopper, a bucket, and give it a quick rinse at the end. Save 8-18 gallons per minute.
  • Wash your car at self-service carwash. Uses 14 gallons of water compared to 100 gallons from a garden hose wash.
  • Use a broom instead of a hose to clean driveways, sidewalks and patios. Save 10 gallons a minute.

Pools

  • Use a pool cover to cut down on evaporation. Save 1,000 gallons a month.
  • Repair pool leaks. A one-inch leak in a 15-by-30 foot pool can waste 102,000 gallons a year.

Indoor Tips

Plumbing

  • Fix leaky faucets and plumbing joints.
  • Install aerators on every faucet and reduce water flow to less than 1 gallon per minute.
  • Insulate water pipes to avoid wasting water while waiting for hot water to flow.

Bathrooms

  • Turn off the water while brushing your teeth & while shaving. Save about 10 gallons a day.
  • Install water-saving shower heads or flow restrictors.
  • Take shorter showers. A standard showerhead uses 2.5 gallons per minute, so a shorter shower can add up in savings.Turn the water off while washing your hair and save 150 gallons per month.
  • When taking a bath, start filling the tub with the drain already plugged instead of waiting first for the water to get warm. Adjust the temperature as the tub begins to fill.An average bath uses 70 gallons when filled to the brim.
  • Capture the water while waiting for hot water to come down the pipes when showering or bathing, and use this water for indoor plants or your garden.
  • If you don’t have a water-efficient toilet, put a plastic bottle or plastic bag weighted with pebbles and filled with water in your toilet tank to displace water so it will use less water per flush. Installing a high efficiency toilet will save 19 gallons per day per person.
  • Check your toilet for leaks by putting dye tablets or food coloring in the tank. If color appears in the bowl without flushing, there’s a leak that should be repaired.
  • Check to assure that your toilet’s flapper valve doesn’t stay open after flushing

Laundry/Dishwashing

  • Run only full loads in the washing machine & dishwasher. Install a water-efficient washer to save 16 gallons per load
  • Replace older appliances with new, water-efficient models. Energy-efficient dishwashers save 3-8 gallons per load. Check with your local water supplier to see if any rebates are available.
  • If you wash dishes by hand, don’t let the water run continuously for rinsing. Use a sprayer to rinse, or rinse all the soapy dishes at once. Or, fill a second sink with rinse water and use that instead.
  • When washing dishes by hand, use the least amount of detergent possible; this will minimize the amount of water needed for rinsing.
  • Let your pots and pans soak instead of letting water run while you clean them.

Other tips

  • Keep a bottle of drinking water in the refrigerator, instead of letting the tap water run to cool it for drinking.
  • Select one glass to use for drinking each day. It will take your dishwasher longer to fill up, and it will not need to be used as frequently.
  • Don’t defrost frozen foods with running water; plan ahead by placing frozen items in the refrigerator the night before, or use a microwave to defrost them.
  • Don’t let the faucet run while you clean vegetables. Rinse them in a filled sink or pan, and use this water for watering your garden or house plants.
  • Use the garbage disposal less. Consider composting.
  • When cleaning out fish tanks, give the nutrient-rich water to your non-edible plants.
