Water Conservation

We live in a Mediterranean climate that is prone to cycles of prolonged droughts.  Some people conserve water to help save a precious natural resource, while others are motivated to save money.  No matter the motivator, the District always encourages the elimination of waste and the efficient use of water.

Easy Ways to Save Water and Money

To achieve the greatest savings, focus on outdoor water conservation. That’s because, in the winter, when water use is lower, the typical water bill ranges from $30 to $80 a month. But in the summer, when water use soars, the typical water bill ranges from $80 to $300 a month.
Most Water is Used Outdoors
  • Oakley Soil is Sandy so Water Shorter, More Frequently. Oakley soil is mostly sand. Landscaping in sandy soil usually responds best to shorter, more frequent watering, such as 5 minutes once or twice a day.
  • Adjust Sprinkler Timers. Many landscapes are over-watered. Each season, reset your sprinkler timers to use less water and avoid large water bills, and once any new landscaping is established.
  • Try Landscaping with Drought Tolerant Plants for Healthier, Easier-to-Maintain Landscapes. They use less water than grass, are often easier to maintain, and save water.
Easy Indoor Water-Saving Tips
  • Fix Leaky Toilets. A toilet that runs can waste many gallons of water per minute. Check for leaks by placing a few drops of dark food coloring in the tank. If colored water appears in the bowl, you have a leak. Adjusting the float, or replacing the flapper, takes only a few minutes and can save a lot of water and money
  • Stop Leaks of All Types. A small faucet leak can waste as much at 170 gallons of water in 24 hours, and much more if the leaks are larger. Generally, the problem can be easily solved by replacing the faucet washers. The back of your water bill has other tips for detecting leaks.
  • Follow Common Sense Water Use Practices. Use full loads in dishwashers and clothes washing machines. Take showers instead of baths. Don’t let water run when you are not using it.

The Bay Area, like only 2 percent of the world, has a Mediterranean climate. This means that we have cool, wet winters and summer droughts.

Thus, it is important to have landscaping that uses drought-tolerant plants, efficient irrigation, and employs other water-saving methods.

CCWD has a water efficient Demonstration Garden that you can visit to see how plants grow using 50 percent less water than a comparable lawn.

Facts About Winter and Summer Water Bills
