I had to say goodbye to my St Aug last year. When the elm tree had to go in the front yard, it opened the door for Bermuda, I am blown away at this stuff
You must have an awesome irrigation system. You're getting 6" of water an hour. I live in FL and even with Cat 3, 4, and 5 hurricanes we don't get 6" of rain an hour. You really should patent your system so others can only run their systems for 5 minutes. It does take about 1200 gallons of water to get 1/2" of water per 4k sq. ft. Sprinkler heads typically use 0.75 gallons per minute (gpm) for ¼-circle, 1.5 gpm for ½ circle, and 3.0 gpm for full-circle heads. Rotor style heads use 2 to 5 gpm each for most residential applications. The average system uses approximately 15-16 gpm per station. You're getting an average of 9 gallons per minute per sprinkler head. You're simply amazing!!!
People are being snarky, but 40m 3 times a week is expensive. I just watched a video from scientists from UF and she said the #1 issue they see is overwatering, and to turn off your irrigation in summer. Let the rain do it, and watch your grass. When it bends and holds footprints, water it 1/2" (however long that is per your tuna cans) once a week; every 2 weeks in winter.
@PinkGrammarGirl That depends on several factors such as how many sq. ft the yard is, irrigation type, drought, etc. We had a very dry Summer in FL. Ponds were down 3-4 ft. so allowing the rain to do the heavy lifting is not always feasible. Summer in many places is the dry season so turning off the irrigation is not the best choice. I use reclaimed water, which many people have, and is $1.20 per hundred cubic feet (CCF). One CCF is equal to 748 gallons and equates to 0.0016 cents which is minimal in the extreme. I'm able to water my lawn for less than $10 per month using reclaimed water. Ft. Myers has a flat fee of $9.50 per month which is more than affordable. Only watering 1/2" once per week when temperatures are 90-95 degrees for weeks at a time will most certainly kill your grass.
