How Much Water Does a Sprinkler Use Per Hour?

Answer

It’s common knowledge that the “American Dream Home” must have a sprawling property with a verdant lawn, but maintaining that grass in pristine condition may be difficult and costly. Anyone who has ever let their children or animals run about in the yard with an oscillating sprinkler for even an hour understands how much the water bill can increase in that short amount of time. Are you curious about the precise amount of water that it is consuming? You may arrive at this conclusion by checking the reading on your water metre or by carrying out a simple experiment.

Tip

Depending on a variety of various circumstances, the quantity of water that is used by your sprinkler in a given period of time may vary, but you are able to calculate the number of gallons that it consumes per minute (or per hour).

Understanding Gallons per Minute

When it comes to watering your grass, you may have issues that go beyond those regarding your water cost. For example, environmental concerns and local water limits may give you pause. This is especially important to keep in mind if you are unsure of the total amount of water that will be consumed each time you turn on your sprinklers. You can figure out how much water your sprinklers use per hour, minute, or second on average by consulting a few useful tools and doing a few simple calculations.

The typical unit of measurement for water consumption is the gallon per minute (GPM). Multiplying any given GPM by 60 is an easy way to convert this to gallons per hour (GPH), but how do you find out what the GPM of a certain sprinkler is?

The RightScape team has created a handy chart that can be used to estimate the GPM of a sprinkler depending on the distance it covers and the breadth that it is either set to cover or meant to cover. To get an approximation of the total amount of water that is being used each minute, add up the GPMs of all of the sprinkler heads.

Gallons Measure Volume

Using the collecting approach, you will be able to determine the amount of inches of water that will be sprayed by an oscillating sprinkler throughout the course of time. The contributors to Today’s Homeowner recommend that you try collecting the water in broad, flat buckets or rain gauges over the course of ten minutes, and then averaging the results to get an accurate reading of the depth. However, how does it translate into gallons when trying to calculate your water bill?

The square footage of a room multiplied by its height is the formula that is used to calculate volume. One unit of volume measurement is the gallon. If you know the coverage area of your oscillating sprinkler in inches and you measure the amount of water it generates in inches per minute, you can figure out how much water it produces overall.

It’s also possible that the company that made your sprinkler head may offer you with this information, or at the very least, an estimate.

Calculating Other Ways

If you want to calculate using the method that was described in Today’s Homeowner, you should first turn on your sprinklers and then position a big wading pool or any other kind of plastic container that is deep beneath the sprinklers. Be careful to point the sprinklers in the direction of the container so that all of the water that is sprayed may be collected by it. Because of this, the spray settings may need to be adjusted so that the water doesn’t go quite as far.

Start on the sprinklers in your yard. They should be allowed to run for precisely ten minutes before being turned off. Make use of a funnel to transfer the water you have gathered into a container of a gallon capacity, such as an old gallon milk jug or a container designed for holding juice. You may calculate the number of gallons of water that were used in ten minutes using this method. Multiply the number of gallons used every ten minutes by six to get the total number of gallons consumed in an hour.

When you initially turn on your sprinklers, it is a good idea to check the water metre in your house to see how much water will be used. This should be situated in close proximity to the point at which the supply line enters your house to provide water inside. Put the number in your notebook. Except for your sprinklers, don’t utilise any other source of water. After allowing the sprinklers to run continuously for the allotted ten minutes, record the reading on the water metre. The difference between the first and second numbers is the amount of water used by the sprinkler in 10 minutes; to get the amount of water used by the sprinkler in an hour, multiply the difference between these two numbers by six.
