Home irrigators are advised to run spray-type systems four times a week for 14 minutes or rotor-type systems four times a week for 51 minutes. Recommended run times are based on average irrigation precipitation rates of 1.5 inches an hour for sprays and .4 inches an hour for rotors.
Adjust accordingly for your own application rates and natural precipitation.
Yard care and water savings tips
Insulate pipes. It's easy and inexpensive to insulate your water pipes with pre-slit foam pipe insulation. You'll get hot water faster plus avoid wasting water while it heats up.
Use your water meter to check for hidden water leaks. Read the house water meter before and after a two-hour period when no water is being used. If the meter does not read exactly the same, there is a leak.
Trickle irrigation and drip irrigation systems help reduce water use and meet the needs of plants. With these methods, very small amounts of water are supplied to the base of the plants. Since the water is applied directly to the soil, rather than onto the plant, evaporation from leaf surfaces is reduced. The water is also placed where it will do the most good, rather than sprayed over the entire garden.
Check all faucets, hoses and connectors periodically for leaks and to make sure they are in good working order. Make sure faucets are closed when not in use. If you do find a leaky faucet, change the washer -- after turning off the shutoff valve.
