Watering your lawn is really important to keep it healthy, but some people might be using too much water.
Too much water can actually harm your lawn, making it grow poorly and get sick. It can also cost you more money.
On the other hand, not giving your lawn enough water can also be a problem. It can stop your lawn from growing properly, make it turn brown, and keep its roots from growing deep into the ground.
To water your lawn just right, it helps to know how your sprinkler system works. This way, you can make sure you’re not using too much or too little water.
When it comes to watering your lawn, there are a bunch of things to think about to do it right.
You have to consider –
- what kind of grass you have,
- what your soil is like, what time of year it is,
- how big your lawn is if it gets a lot of shade,
- and even how flat or sloped your yard is.
There are different ways to water your lawn, and some might work better for your lawn than others.
Plus, if you put your lawn irrigation system in the right spot and take care of it, you can save more water.
Considering Water Needs
To save water and make sure your lawn stays healthy, the first thing to do is figure out how much water it really needs.
Sometimes, people use more water than necessary.
Most experts say that for a regular lawn, it’s enough to get about an inch to an inch and a half of water every week.
This can be from rain or watering it properly. But the timing and how you water your lawn also matter.
Two big things affect how much water your landscaping needs:
- and transpiration, which we call evapotranspiration or ET.
Think of ET as the opposite of rainfall.
It’s the amount of moisture that goes away because of evaporation and plants breathing out moisture. Things like temperature, humidity, and wind affect ET.
Knowing the exact ET can be tricky, especially for regular homeowners. But it’s good to know that ET matters for how and when you water your plants.
It’s better to water in the morning or early evening because the water has more time to soak into the ground without disappearing because of the hot sun.
This is why it’s also better to water deeply a few times a week instead of watering lightly every day. Light watering makes more water disappear through ET.
To find out how much water your lawn needs for one inch of coverage, you start by calculating the size of your yard in square feet.
Then, you multiply that number by 0.623, which gives you the amount of water required.
For instance, if your lawn measures 40 by 40 feet, totalling 1,600 square feet, you’d do this math: 1,600 (square feet) x 0.623 = 996 gallons of water. So, to give your entire lawn a one-inch deep soaking, you’d need 996 gallons of water.
Using water efficiently is important to save resources. The type of watering system you choose can make a big difference.
As the name suggests, drip irrigation is a method that slowly and steadily provides moisture to the soil, allowing plants and grassroots to use it efficiently.
There are two main types of lawn irrigation with drip systems: surface and subsurface systems.
In a surface system, water drips onto the ground’s surface, while a subsurface system is buried underground to deliver water directly to the roots.
Drip irrigation has been widely used in agriculture to cultivate high-value crops and is now becoming increasingly popular for residential yards and gardens.
Advantages of Drip Irrigation
- Drip irrigation is super efficient at getting water right to the plant roots, preventing wastage by not spraying unnecessary areas or letting water evaporate.
- It’s great for watering tricky spots and dense plants that are hard to reach with traditional methods.
- Farmers love using it for valuable crops, and it’s catching on in backyard gardens for plants like tomatoes and peppers, reducing weed growth.
- It’s perfect for uneven terrain because it avoids pooling water and eliminates runoff, which is better for the environment. Some systems can also dispense fertilizers and pesticides.
- Drip irrigation responds quickly to plant needs, starting and stopping as necessary. It can even sense when it’s raining and pause until it’s dry again.
- You can customize it to water specific areas, avoiding unnecessary watering in places that don’t need it.
Understand the Equipment
To make sense of how a drip irrigation system works and choose the right one for your home, it helps to know the basic parts involved:
- Backflow Preventer: This gadget connects to your home’s water faucet and ensures that water used for gardening doesn’t flow back into your home’s water supply.
- Water Pressure Regulator: Attached to the backflow preventer, it keeps the water pressure in the drip system at safe levels. Without it, the system could get damaged due to the high water pressure in a typical home.
- Filter: The filter plays a vital role by trapping dirt and tiny particles, preventing them from clogging the drip tubes and emitters.
- Main Line and Drip Tubing: The main line carries water from the source, often the filter, closer to where it’s needed. From there, flexible drip tubing directs the water to the desired area, making it easier to position.
- Emitters: These are small sprinkler heads spaced about every 18 inches along the drip tubing. They control how much water drips onto the plant’s root zones.
- Control Valves: These valves offer you more control over where the water flows around your home. You can send more water to specific zones or circuits and less to others, depending on the type of plants you’re watering.
A home lawn sprinkler system is a setup that spreads water across your yard and garden using various equipment.
People usually have these systems to make watering their lawns easier, as doing it by hand can take a lot of time. These systems can also efficiently water plants, trees, flowers, and even veggies.
They can be as basic as a sprinkler attached to a hose or a complex network that waters your yard automatically, on a schedule, or when needed. In this section, we’ll focus on professionally installed, in-ground automated systems.
Advantages of Sprinkler Systems
- Sprinkler systems are popular because they make watering your yard convenient.
- Automated in-ground sprinkler systems eliminate the need to drag hoses and set up sprinklers.
- Professionally installed systems ensure proper watering coverage and reduce water waste.
- They help keep driveways and sidewalks dry.
- These systems can make your yard look greener and more attractive, adding value to your home.
- Sprinkler systems are compatible with various soil types except for clay.
- They work well with chemicals and fertilizers and don’t compact the soil.
- Sprinklers can protect plants from frost damage in frost-prone areas.
- They are especially useful in large yards and areas where frequent watering is necessary.
- In-ground sprinkler systems offer a convenient way to ensure your yard gets a good soaking, even when you’re not home.
Understand the Equipment
- Understanding your in-ground sprinkler system layout and components can help with maintenance and potential DIY installation.
- Municipal water is delivered to your home through a supply line monitored by a water meter.
- A sprinkler system access pipe and shut-off valve are located between the water meter and your house.
- The shut-off valve allows you to turn off the irrigation system without affecting your home’s water supply.
- Next, a backflow prevention system must be installed to prevent water from flowing back into your home.
- The type of backflow prevention system depends on local building codes.
- The sprinkler system valve keeps water under pressure and is controlled by low voltage.
- Water flows through mainlines, sub-lines, and lateral lines placed underground, connecting to sprinkler heads.
- Sprinkler heads come in various types, including fixed position, rotor, multi-stream rotary, and impact rotary.
- Fixed position heads spray water in different patterns, while rotor heads spin and throw water farther.
- Multi-stream rotary heads are great for medium-sized areas and slopes, reducing runoff.
- Impact rotary sprinklers are durable and suitable for well water or hard water use.
Smart irrigation systems have ushered in a new era of convenience and efficiency for homeowners.
Instead of relying on simple timers, these lawn irrigation system installations use sensors to keep an eye on soil moisture levels and gather information from plant care sources and weather predictions.
This helps them decide when and how much water their plants need for optimal health. These smart-systems not only conserve water but also reduce your water bills.
Plus, you can control and monitor them remotely using your smartphone, and many of these systems are budget-friendly.
