Irrigation systems price by the zone: $975 to $1,350 per zone installed, and most zones land around $1,250. Southlake projects start around $5,500 for a small lot with 4 to 6 zones, a standard lot with 6 to 10 zones runs $8,500 to $15,000, and large or acreage properties with 10 to 20+ zones run $13,000 to $28,000+. A typical 6 zone system lands between $8,500 and $9,500, and adding drip to beds runs $800 to $2,500, usually as its own zone.
This page covers new systems installed with a new or redesigned landscape, not lawn maintenance.
What each system size costs
| System size | Typical range | What it covers |
|---|
| Small lot (4-6 zones) | $5,500-$9,500 | Compact yard, turf and a few beds. |
| Standard lot (6-10 zones) | $8,500-$15,000 | Typical yard, front and back, beds on drip. |
| Large or acreage (10-20+ zones) | $13,000-$28,000+ | Bigger Southlake lots with formal beds, and pots and specimen trees on their own lines. |

What actually drives the price
- Zone count. Southlake properties are big, and the zone map follows the property. A half-acre lot with real planting can take a dozen zones, because turf, beds, pots, and trees each want their own valve and schedule.
- Drip vs spray. Turf goes on rotors or sprays, beds go on drip. The more planting a landscape carries, the more zones it earns.
- Controller and backflow. A few pieces sit outside the per-zone number: a weather based smart controller runs about $675 installed, and the backflow preventer Texas requires runs about $850. Permit fees vary by city.
- Watering rules. Southlake publishes its own watering schedule; check the current one with the City of Southlake, and let the controller keep the system inside it.
- Digging through clay. Trenching here is slow work, and in an established yard the care taken putting the lawn and beds back is half the job.
New system or retrofit?
Plenty of Southlake systems were sized for the original builder landscape and now serve added beds, a pool deck, and trees that doubled in size. Before proposing anything we test what exists: water pressure, flow at the meter, and what each valve actually covers. Sometimes redesigning a few zones fixes the problem, and when a full replacement makes sense you see the per-zone math in writing.
Irrigation as part of the bigger project
The cheapest time to run irrigation is when the ground is already open, and sleeves belong under a patio or pool deck before it is built. If a patio is in the plan, our Southlake paver patio cost guide covers that side of the budget. Beds belong on drip; our guide to drip irrigation for new landscape beds covers how bed zones get planned, and it is how we build our irrigation work generally.
