Sprinkler System Installation and Repair in Austin
An irrigation system in Central Texas has a harder job than in most of the country. It has to keep a landscape alive through weeks without rain, while running only on the days your utility allows, and survive freezes that split above-ground components. Most systems around Austin do none of those three things well, and the owner pays for it on the water bill every month.
We design, install and repair irrigation across Austin, Cedar Park, Leander, Round Rock and the surrounding towns. Here is what that actually involves here.
In Texas, irrigation work requires a state license
This is worth knowing before you hire anyone. Texas requires a TCEQ licensed irrigator to install, alter, repair or service an irrigation system. It is not a formality: the license covers backflow protection, which is what keeps irrigation water from siphoning back into your drinking water supply. Most cities also require a permit and inspection for a new system.
If a bid comes in unusually low, the licensing question is usually the reason. Ask for the irrigator license number before work starts.
The watering schedule is set by your utility, not by you
Austin operates year-round conservation rules. Automatic irrigation is limited to assigned days based on your address, and watering during the middle of the day is prohibited because most of it evaporates before reaching a root. Cedar Park, Round Rock, Leander, Georgetown and Pflugerville each run their own schedules and their own restriction stages.
That changes system design. A landscape that needs water four days a week cannot be kept alive on a one-day schedule, no matter how good the controller is. The design has to fit the schedule you are legally allowed to run, which usually means fewer, deeper cycles and drip where drip belongs.
Cycle and soak: the technique most systems here are missing
On blackland clay, water applied faster than the soil can absorb it runs off toward the street. You pay for it, the lawn never gets it. The fix is cycle and soak: instead of one long run, the controller runs a zone for a short period, pauses to let water absorb, then repeats. Same total water, dramatically more of it actually reaching roots.
Most controllers can do this and most are not programmed for it. On the caliche side of town the problem inverts: water drains through fast, so shorter and more frequent beats long and deep. Same equipment, opposite programming, and it depends on which side of the metro you live on.
Zones that make sense
Turf, beds and slopes should never share a zone. They absorb water at different rates and need different run times. Mixed zones are the single most common design fault we find, and they guarantee that something is always either drowning or dying.
Drip where it belongs
Beds, borders and foundation planting belong on drip, not spray. Drip puts water at the root instead of on leaves and pavement, and it is unaffected by wind. Austin Water offers rebates for converting spray to drip, generally with pre-approval required before work starts.
Freeze protection
Central Texas freezes are infrequent enough that people forget them, then lose backflow assemblies and exposed valves in a single night. Insulating the assembly and knowing where your shutoff is costs almost nothing and prevents the most expensive repair on this list.
Repairs we get called for most
- Broken or sunken heads — mowers, vehicles and settling clay
- Heads spraying the driveway — misaligned arcs wasting a third of the zone
- Leaking valves — a zone that never fully shuts off
- Low pressure — usually a leak on the mainline, sometimes too many heads per zone
- Freeze damage — cracked backflow assemblies after a hard night
- Controller programmed for the wrong stage — running on days your utility does not permit
- Coverage gaps — the dry patch that no amount of extra watering fixes
- Backflow assembly due for testing — many Texas utilities require annual testing
How to know your system is wasting water
Run each zone manually and walk it. You are looking for water on pavement, misting instead of droplets, heads that do not pop fully, and dry gaps between heads. Then check the meter with everything off: if it moves, you have a leak.
Texas A&M AgriLife runs WaterMyYard, a free service that publishes weekly watering recommendations for Central Texas based on local weather station data. It tells you how much your lawn actually needs that week, which is almost always less than a default controller schedule assumes.
What actually drives the cost
Bids vary widely for the same yard, and the differences are usually these:
- Number of zones. Driven by water pressure and flow, not by yard size alone. A property with low flow needs more zones for the same coverage, and each zone adds valve, wire and labor.
- Soil and rock. Trenching through blackland clay is straightforward. Trenching through caliche and limestone in Cedar Park or Bee Cave is a different job with different equipment.
- Head type. Rotary heads cover more per head on open turf; spray heads suit tight areas. Mixing them badly is cheap up front and wasteful forever.
- Backflow assembly. Required, and the type depends on your utility and site conditions. This is not the line item to shop on.
Are smart controllers worth it here?
Generally yes, with one condition. A weather-based controller adjusts run times to actual conditions instead of a fixed schedule, which in a climate that swings from drought to downpour saves real water. Austin Water has offered rebates on qualifying models.
The condition: a smart controller on a badly designed system just wastes water more intelligently. If zones mix turf and beds, or coverage has gaps, fix that first. The controller optimizes what it is given; it cannot correct a layout fault.
How long a system lasts
A properly installed system runs 15 to 20 years, but not untouched. Heads get damaged by mowers and settle as clay shifts, so expect to replace a few each year. Valve diaphragms wear out around the 10 year mark. Controllers usually fail before the buried components do, and are the easiest part to upgrade.
The buried mainline and lateral lines are what determine whether a system is worth repairing or replacing. If those are sound, almost everything else is a serviceable part.
Free irrigation inspection
Before quoting anything, we check coverage, pressure, zone design and controller programming, and tell you which of those is actually costing you money. Often the fix is programming rather than parts.
See our free irrigation inspection, or pair it with core aeration — opening compacted soil is what lets the water you already apply reach roots. It works alongside lawn care and low-water planting for landscapes designed to need less in the first place.

Frequently asked questions
Does Texas require a licence for irrigation work?
Yes. Texas requires a TCEQ licensed irrigator to install, alter, repair or service an irrigation system. The licence covers backflow protection, which keeps irrigation water from siphoning into your drinking supply. Ask for the licence number before work starts.
How do I know if my sprinkler system is leaking?
Turn off everything that uses water and watch the meter. If it moves, water is going somewhere. Then run each zone and check the meter during each one; the zone with a disproportionate spike is the one with the problem.
What is cycle and soak, and do I need it?
Instead of one long run, the controller runs a zone briefly, pauses to let water absorb, then repeats. On blackland clay it is the difference between water reaching roots and water running to the street. Most controllers can do it and most are not set up for it.
How much does a sprinkler system cost in Austin?
It depends on zone count, which is driven by your water pressure and flow rather than yard size alone, plus soil type. Trenching through caliche in Cedar Park is a different job from trenching clay in Pflugerville, and the backflow assembly type varies by site.
Do I need to winterize my system in Central Texas?
Not the full blow-out used in colder states, since the ground rarely freezes deep enough here. What does need protecting is the backflow assembly, which is above ground, holds water and is expensive to replace.
