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.

As much as 75% of your summer bill can be for outside watering. So to achieve the greatest water savings, focus on outdoor water conservation. (Blockquote)

Most Water is Used Outdoors (h4)

  • 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, 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.
