Sprinkler system cost in 2026: spray, smart and drip irrigation on three lawn sizes
What an in-ground sprinkler system costs on a 2,000, 4,000 and 6,000 sq ft lawn, whether a smart controller and drip lines are worth it, the backflow preventer most codes require, and what an irrigation quote should include.

Spray, smart or drip?
- Spray heads on a timer: the cheapest. Waters on schedule whether it rained or not.
- Smart controller and rain sensor: skips watering after rain and adjusts through the season. Typically cuts outdoor water use by 20–30%.
- Drip for beds, rotors for lawn: water at the roots instead of on the sidewalk. Best for yards with beds, shrubs and trees as well as grass.
What an irrigation quote must include
- Number of zones, and which areas each one waters
- Head types (spray, rotor, drip) per zone
- Controller model, and whether a rain or soil sensor is included
- Backflow preventer and permit
- Repair of lawn and beds after trenching
Watering rules
Austin, like many Texas cities, limits automatic sprinklers to assigned days and hours, and tightens the limits in drought. A smart controller can be set to follow them, and water running into the street can be reported to the city.
