(sunny / good drainage) Apply min 1/2" each water day - minus rainfall * since last watering :
 "fixed - spray" |
 "rotating" |
| 1/2 " = 10 - 15 + minutes ** |
1/2 " = 30 - 45 + minutes ** |
** per spacing, nozzle & wind use average measure of multiple catch cans 5 ft + from heads
| water early : |
cool (low evaporation) less wind (best coverage) |
| separate programs: |
schedule like stations together by water frequentness req. |
| reduce runoff : |
split water day into multiple cycles (2+ start times per pgm) |
| winter drought : |
supplement lack of 1/2" rain every 1 - 2 weeks, as needed |
|
| *rain-freeze sensor : |
prevent system operation after receiving measured rainfall |
 |
cancels watering prior to freeze reducing icy walkways |
| lower watering cost /reduce saturation after wet weather |
