Having a lawn sprinkler system is a great way to keep your lawn looking lush and green. But how do you know how much water your lawn needs? Calculating the amount of water needed for your lawn sprinkler system is easy. To start, you need to figure out the size of your lawn. To do this, simply multiply the width by the length of your garden in feet to get the number of square feet of area.
Then, multiply that figure by 0.623 to get the number of gallons used (or use our calculator).For example, if your garden is 10 feet wide and 20 feet long, you would have 200 square feet of area. Multiply that by 0.623 and you get 124 gallons of water needed for your lawn sprinkler system. This illustration is an example of a fairly standard 3-valve sprinkler system. While the amount of water needed will vary depending on the climate, climate and time of year, the general rule of thumb is to ensure that your lawn gets 1 inch of water per week in dry conditions. To make sure you are providing enough water for your lawn, you can use a rain gauge or soil moisture meter to measure how much water your lawn is getting. This will help you adjust your watering schedule accordingly. By following these simple steps, you can easily calculate the amount of water needed for your lawn sprinkler system and ensure that your lawn stays healthy and green.
