Introduction to Irrigation
A sustainable garden provides many benefits and uses few resources, including water. All across Southern California demand for water is increasing and supplies are diminishing. But installing appropriate irrigation based on the information in this section can save tens of thousands gallons per garden each year.
This section provides detailed information so you can design, install and maintain your irrigation system successfully.
Facts:
| • | On average, 40-70% of a property’s water use is for irrigation. |
| • | A typical sprinkler system applies 2-3 times more water than any soil can absorb. |
| • | A well designed and installed drip irrigation system may reduce water use by 80% compared to sprinklers. |
| • | Plants need a balance of oxygen, water and nutrients in the root zone. Over watering suffocates plants, causes the roots to rot, and makes the plant work harder to survive. |
| • | Automatic sprinklers may increase a property’s water use 2-3 times. |
| • | An irrigation system that has leaks, broken parts and isn't working properly can be the biggest water-waster of all – wasting thousands of gallons each month and costing you money. |
