I'm hoping they didn't just set all zones the same for all 3 days instead of customizing zones based on what was is in those zones;if all bushes you require less time, grass more time;another saving technique is to water grass zones twice on water days (cut time in half) ;come back around a 2nd time and water again;set time to start 2nd watering about 10 minutes after first watering;this allows the water to soak in instead of running down the street;I run grass zones twice and bushes once;bushes 10 mins twice a week is good, winter 7 or 8 mins;also cut grass areas during fall & winter;I do my own landscaping and irrigation set up;I replaced all original hunter sprinklers (myself) with different Hunter rotors for better coverage in grass areas (Hunter PGP or I-20 for large areas (22 to 52 ft) overlapping coverage;(Hunter PGJ 18 to 25 ft areas);due to size of yard, I suspect you already have rotors;I use only hunter sprays because they work better than others and are easier to swap out and adjust if needed;also using hunter sprays C5530 5ftX30FT on sides between yards which uses less water as they spray 5ft out and 15ft each side so you are not watering neighbor's yard;I replaced my Acclaim controller with a new Hunter PRO-C along with a wireless water sensor (installed myself);also wrote up easy to follow instructions for my neighbors so they can set up their own times so I don't have to keep doing it;have you turned on each zone and walked around to make sure you don't have a busted sprinkler head (look under bushes for hidden ones). If you have a Hunter PRO-C no matter old or new I can send you a PDF copy which will explain how to test zones and set up times etc...email me at wilbbb@msn.com and I will send you a copy;good luck

+1 on the B-Hyve, very smart system, reduced my consumption significantly

Many of us were told there were rain sensors in the sprinkler heads which is not true. There has no been a rainy season this year in many parts and we have no say so in the water bill. Villages bought water company and have a monopoly on everything.

How is it possible to do that? Outside spigots are potable water, not irrigation water to the best of my knowledge.

I have a corner lot use about 11k monthly. My lawn is deep green. However, I do my own lawn maintenance. Years ago I was in the business.

Just wondering...

I have a Courtyard villa on a corner lot. I have 84 (yes 84) sprinkler heads spread out over 7 zones. I use between 5k-12k gallons / mo. I am a snow bird but keep eye on yard with camera and yard care person. Grass is doing fine. Get yourself a B-Hybe sprinkler controller. Very easy DYI install. Then u can control from anywhere.

I also have a larger than average (pie shaped) lot. Installed the Rachio system with a water meter a year ago and it works great. It lets me know how much water I use at any time and will automatically turn off a zone if a head breaks and send me a text and email to let me know. It is very easy to install and has saved me a lot of water. If you would like to see how it works you can send me a private message.

I’ve got the same issue but my bills are even higher. Pls let me know what ends up working for you. Thanks

I turn mine off
 

I am a snow bird and when I leave for the summer I turn my sprinklers off. I ask my neighbor if my lawn looks dry, turn them on for a week. I don't think he has ever turned them on. By the way, moisture sensors don't work. Like someone else posted, 2 hrs after a down pour or a week of constant rain, they dry out and turn your system on again.

You are only supposed to water two times per week and your days should be shown on your sprinkler controller. Your lawn care person doesn't know what he is doing.

For that size lot you should be using about 10,000 gallons per month for Zoysia. Set your Hunter controller to water every 5 days (Go to "Water Days" and press the left arrow. Set the left number to "5"). The Hunter MP Rotator lawn heads put down an inch of water in about 70 minutes of runtime. That will soak the ground to about 8 inches. I disconnected the wonky outdoor sensor by pulling the bottom green sensor wire in the control box and then flipping the front switch to "Bypass". It is imprtant to water deep and infrequent so that the Zoysia roots will go into the ground.

I also have a corner lot and large gardens in my backyard, my bills are
May 21,220

You are definitely using too much water for irrigation. I have a corner lot and use between 11,000 and 20,000 gal per month, depending on the rain this summer. I run it three times per week. If you have a qualified person checking your system they should be able to pinpoint any problem that you're having. They need to check every sprinkler head and the rain/temperature sensor to see if it's ok. You also may have a leak somewhere.

My lot is on corner and measures with house on it 10340 sq/ft . House is lantana w/3car garage so figure 3300sq/ft plus driveway not watered. 44 sprinklers in grass plus the bushes. Five zones. What size is your lot? Interested to know because I think mine is huge compared to others. Like half a dog park big on the side.

Used 19k in September and 22k in October . I ran it an extra cycle one week due to lawn treatment. Set to twice a week, hour per zone, irrigation company said new heads put down half as much as old ones so I should be getting an inch a week. Seasonal and rain monitor on. We are also not there, so dont know much about if it ran long or short. Do know grass was brownish compared to neighbors first week of October but I put some fertilizer down and greened up in week.

So what size is your lot?
