For commercial properties, a well-maintained, lush lawn doesn’t only look great; it creates a welcoming atmosphere, enhances property value, and exudes care and professionalism.

However, maintaining a large lawn green requires more than occasional watering. Moreover, using only one gardening hose to hydrate the ground may not be the smartest idea.

This is where a sprinkler system comes in. A specially designed commercial irrigation system can provide the efficiency and consistency large-scale landscapes need.

According to sprinkler and pipe installation companies in the UAE, sprinkler systems can effectively maintain large lawns without the hassle of manual watering. They save time and water since they ensure even coverage across every inch of grass.

Modern irrigation systems can also be preprogrammed to turn on at optimal times, like early morning or late at night, to reduce evaporation and keep water usage in check. With advancements in home automation installation, smart irrigation systems can now be integrated with climate and soil sensors, ensuring water is used efficiently based on real-time conditions.

Opting for an underground sprinkler system takes these benefits a step further. Unlike above-ground alternatives, this option ensures that most of the fixtures are discreet so you can maintain the aesthetic appeal of your lawn.

Underground sprinkler systems also eliminate the risk of tripping hazards or damage to hoses and fixtures. With the pipes buried below the surface, this feature is shielded from weather and wear, which can help extend its lifespan.

Things to Know About Installing Pipes for In-Ground Sprinkler Systems

Sprinkler systems require careful, proper installation to guarantee their functionality and efficiency. The pipes, in particular, also need to be expertly connected and placed to ensure they work correctly.

Below are the best tips to remember when installing pipes for a commercial in-ground sprinkler system:

1.     Plan the layout and mark utility lines.

To ensure a successful project, you should have a well-thought-out, detailed layout of the sprinkler system.

Work with a service provider to create a sketch or blueprint that maps out where each sprinkler head and pipe should go to ensure proper coverage and prevent gaps and overhydration of the lawn.

Find and mark all underground utility lines in your plan as well. Check the property’s layout and contact the appropriate local authorities if your lawn is near a public area to avoid hitting water, gas, or electrical lines.

Once you have a plan, mark the lawn accordingly using stakes, flags, or chalk.

Proper planning and marking ensure that workers can easily follow the blueprint and prevent disruptions and potential issues from coming up.

2.     Select the appropriate pipe material.

The most used pipes for underground sprinkler systems are polyvinyl chloride (PVC) and polyethylene (PE).

PVC pipes are durable and recommended for areas with minimal ground movement. They are well-suited for main lines and areas that need high water pressure.

Conversely, PE pipes are flexible and best used in areas with shifting soil or colder climates since they’re less likely to crack from freezing.

Consider lawn conditions, required water pressure, and climate when selecting pipes. Regardless of the material you choose, make sure they are designed for outdoor and underground use and can withstand pressure and environmental factors.

When designing your lawn’s aesthetic, the attention to detail can feel akin to designing with Swarovski crystals—precision, quality, and durability are key elements that make a significant difference. Similarly, choosing the right pipes ensures your sprinkler system performs beautifully and lasts for years.

Ask your sprinkler system installation service provider and pipe suppliers for the best type of pipes they can recommend for your project if you are unsure which one to get.

3.     Dig trenches with suitable depth.

The ditches should be deep enough to protect the pipes from external damage and temperature changes.

A depth of six to 12 inches is usually sufficient for installation. However, check the local building codes to see if they have specific requirements.

The sprinkler system installation company may also dig deeper based on the piping material and climate in your area.

Since you have a large lawn, make sure a trenching shovel or a machine is used to achieve consistent depth. Your service provider should also aim for straight, even trenches to make pipe installation easier.

4.     Install a backflow prevention device.

A backflow prevention device stops irrigation water, which might contain fertilizers or debris, from flowing back into your home’s clean water lines.

Local codes in some cities require this device to be added to the sprinkler system, so have one installed. But even if you’re not legally required to include it, consider doing so since it helps prevent debris from clogging the pipes.

The backflow preventer should be compatible with your system’s pressure and pipe size. It must be installed in the area where your sprinkler system connects to the main water supply. Make sure it’s accessible for maintenance and positioned above ground if required.

5.     Use proper fittings and connections.

A sprinkler system requires connecting the pipes with couplings, elbows, tees, and other fittings. Make sure these piping accessories match your pipe material.

If you’re using PVC pipes, you need solvent-weld fittings. For PE pipes, opt for barbed fittings and clamps.

Your contractor will know which pipe joining method and processes are best for the project. For instance, PVC pipes require a primer and cement to create a watertight bond.

Your contractor should also double-check each connection to ensure they are tight and properly aligned.

6.     Test the system before backfilling the trenches.

Once all pipes, fittings, and sprinkler heads are in place, turn on the water to check for leaks, uneven pressure, or malfunctioning heads. Have your contractors adjust or repair any issue immediately to avoid digging up finished work later.

With the water still on, walk around the lawn and observe sprinkler head performance. Look for uneven spray patterns and ensure water reaches all target areas.

If pressure seems low, have your contractor inspect for blockages or improperly sealed connections.

7.     Ensure the trenches are backfilled properly.

After testing the sprinkler system and ensuring it functions correctly, ensure the trenches are backfilled correctly.

The steps involved in this process often include:

• Layering the soil correctly
• Placing a soft, stone-free layer directly around the pipes for cushion and protection from punctures and cracks
• Filling the trench with compacted soil in stages
• Smoothing the surface, replanting grass, and adding plants to restore the lawn

Proper backfilling prevents damage to the pipes and reduces the risk of future problems like uneven settling or water pooling. Additionally, it restores your lawn’s look and appeal.

A lawn can be another appealing selling point for commercial properties. A properly installed sprinkler system can help you maintain yours better.
