They are all professionally maintained, and use less water per acre than most condominium projects. On the average, a typical golf course within the DWA's service area uses 7 acre-feet of water per landscaped acre each year. Two golf courses and a city park are currently using unrestricted use tertiary treated recycled water for irrigation, and negotiations are underway with others. Recommended Watering Times Optimal watering times vary depending on the type and condition of your sprinlers, the types of plants used, exposure of the area being watered, and the efficiency of your irrigation system. It is, therefore, not possible to suggest recommended watering times without treating each site individually.
Most people do tend to over water, however.
A good rule of thumb is to reduce your watering times by no more than 10 percent at a time. If you reduce the amount too much all at once, it can cause plant stress, and they may exhibit dieback. After watering at the reduced level for a couple of weeks, try reducing the water 10 percent more. If the plants still look good after a few weeks, lower your times again. If they've turned a little brown or if the leaves are curling, increase the watering time.
