How We Install Underground Sprinkler Systems Without Tearing Up Your Yard

One of the most common concerns we hear from Omaha homeowners considering a new sprinkler system is about the installation process itself. People picture their yard being torn up, trenches running across the lawn, and weeks of recovery before the grass looks normal again. It's a reasonable concern — and for some types of underground installation, it's a legitimate one. But the way Alternate Rain installs sprinkler systems is fundamentally different from what most people imagine, and the process is a lot less disruptive than you might expect.

Here's exactly how we do it.

The machine that makes it possible

The centerpiece of our installation process is a pipe-pulling machine — a piece of specialized equipment that drives a steel blade through the soil and simultaneously pulls poly pipe behind it as it moves. The blade cuts a narrow slice through the ground just wide enough to thread the pipe through, and as the machine moves forward the soil closes back in behind it. There's no open trench, no major excavation, and no significant disruption to the surface of your lawn.

If you've seen the video we recently posted on our Instagram showing the machine in action, this is exactly what you were watching. The poly pipe is fed by one of our crew members who walks alongside the machine, unwinding and guiding the pipe by hand as it gets pulled into place underground in one smooth, continuous motion. What looks like a complex process from above is actually remarkably clean and efficient — and it's one of the main reasons our installations cause so little damage to your existing lawn.

What poly pipe is and why we use it

The pipe being pulled through the ground is polyethylene pipe — commonly called poly pipe — and it's the material of choice for residential irrigation systems throughout the Omaha area. Poly pipe is flexible enough to be pulled through the ground without requiring an open trench, durable enough to withstand decades of underground use, and resistant to the freeze-thaw cycles that Nebraska winters put the ground through every year.

Its flexibility is also what makes our self-draining system design possible. Automatic drain valves installed at the low points of each zone allow water to drain naturally out of the pipes after every watering cycle, which means there's nothing left in the lines to freeze and expand during winter. No blow-out required — the system takes care of itself.

How a full installation works from start to finish

Before the machine ever touches your yard, we spend time walking the property and planning the system layout. We determine where each zone will run, where heads will be placed for head-to-head coverage, where the valve box will be located, and how the mainline will route from your backflow preventer to the valve box. This planning phase is what separates a system that works well from one that leaves dry spots or wastes water — and it's where our 40-plus years of experience in the Omaha area makes a real difference.

Once the layout is planned, installation moves quickly. The pipe-pulling machine runs the lateral lines for each zone. Heads are installed at the planned locations, saddle tapped into the poly pipe at the appropriate spacing. The valve manifold is assembled inside the valve box, which connects to the mainline at a single point. From the valve box, poly pipe runs out to each individual zone, feeding water to the heads when that zone is called by the controller. The controller is mounted and wired to each zone valve. The backflow preventer is installed at the water supply connection point.

From start to finish, most residential installations are completed in two to three hours. Corner lots or larger properties may take a half day. Only a large acreage or a particularly complex property would require a full day or more. By the time our crew leaves your property, your system is operational, every zone has been tested, and your yard looks essentially the same as it did when we arrived — minus the new sprinkler heads sitting flush with the surface.

What your lawn looks like after installation

The most visible evidence of a new installation is the narrow slice marks left by the pipe-pulling blade running across your lawn. These are thin lines in the turf — typically no wider than an inch — and they close back in naturally within a few days as the soil settles. If your lawn is actively growing, the grass fills back in quickly and the lines become difficult to spot within a week or two.

We also take care to keep the installation as neat as possible around head locations, valve boxes, and the controller mounting point. Any areas where more significant digging was required — typically at the valve box location and backflow preventer — are filled and tamped back down before we leave.

It's worth noting that in yards with large mature trees, the installation can occasionally be a bit more involved. Dense root systems — particularly from trees like river birch and locust, which are common in Omaha neighborhoods — can require additional maneuvering around root zones to get pipe in place without causing damage. In these situations a small amount of extra hand digging may be needed in specific areas. It's the exception rather than the rule, and we'll always let you know upfront if your property has features that might affect the process.
