Watering your lawn is an important task to keep it healthy and green. However, you may wonder how long and how often you should water your lawn. In this article, we will explain how to calculate the watering time and amount of water you need based on some factors such as the type of grass, the soil condition, the weather and the season.
One way to measure how much water your sprinklers use by reading your water metering system is to follow these steps:
- Locate your water meter, which is usually near the street or in the basement of your house. It should have a dial or a digital display that shows the amount of water used in cubic feet or gallons.
- Write down the current reading on the meter before you turn on your sprinklers. You can also take a picture of it for reference.
- Turn on your sprinklers and let them run for a fixed period of time, such as 10 minutes. Make sure that no other water is being used in the house during this time.
- Turn off your sprinklers and check the meter again. Write down or take a picture of the new reading.
- Subtract the first reading from the second reading to get the amount of water used by your sprinklers in 10 minutes. For example, if the first reading was 1000 gallons and the second reading was 1025 gallons, then the water used by your sprinklers was 25 gallons in 10 minutes.
- Divide the water used by your sprinklers in 10 minutes by 10 to get the amount of water used by your sprinklers in one minute. For example, if the water used by your sprinklers was 25 gallons in 10 minutes, then the water used by your sprinklers was 2.5 gallons Or 9.5 Liter in a minute.
This method will give you an estimate of how much water your sprinklers use per minute based on your water metering system. You can use this information to adjust your watering schedule according to your lawn’s needs and the weather conditions. You can also compare it with other methods of measuring your sprinklers’ water use, such as tuna cans or measuring cups.
Measuring Cups
To measure how much water your sprinklers use, you can follow these steps:
- Place some containers, such as tuna cans or measuring cups, on the ground in the area that your sprinklers cover. Make sure to spread them evenly and include the edges of the spray.
- Run your sprinklers for 15 minutes and then turn them off.
- Use a ruler to measure the depth of water in each container. Write down the measurements or take a picture of them.
- Add up all the measurements and divide by the number of containers. This will give you the average amount of water that your sprinklers use in 15 minutes.
- Multiply the average by 4 to get the amount of water that your sprinklers use in an hour. This is usually expressed in inches per hour.
For example, if you have four containers with 0.5, 0.75, 0.25, and 0.5 inches of water respectively, then the average is (0.5 + 0.75 + 0.25 + 0.5) / 4 = 0.5 inches per 15 minutes. Multiplying by 4 gives you 2 inches per hour.
You can use this information to adjust your watering schedule according to your lawn’s needs and the weather conditions. You can also check for any problems or inefficiencies in your sprinkler system, such as low pressure, broken nozzles, or uneven coverage.

To help the grass in the field absorb water, you need to follow a correct watering regime. First, you need to keep the root zone moist. Then, you need to balance between keeping the plant alive and avoiding over-watering.
The right watering cycle depends on your garden’s features. This will let the grass grow deeper and stronger and prevent diseases and pests.
The rule of thumb is 4 liters per square meter, per day at the peak of the season. But, the watering regimen also depends on the season, the soil type, the watering method and the shading in the area. In any case, water the grass between 6:AM and 4:PM for all types of grass.
Correct watering means even watering and efficient watering.
Now that you know how much water your sprinklers use (Liter per minute) and you know the size of your lawn, you need to choose how many liters per square meter you want to water, remember! This figure varies depending on the season/weather and your soil type.
All you need to do now is to put the numbers into the right fields and you will get a result of the irrigation time required according to the day interval
