Watermatic Irrigation — Irrigation in Hornsby

A basic pop-up sprinkler system for a suburban lawn (up to 500m²) costs $2,000–$5,000 installed. Drip irrigation for garden beds costs $1,500–$4,000. Full garden irrigation systems for larger properties cost $5,000–$15,000+. Smart irrigation controllers add $300–$800 but can reduce water usage by 30–50%.

Pop-up sprinklers suit lawn areas — they retract when not in use and cover large areas efficiently. Drip irrigation (micro-drip emitters) delivers water directly to plant root zones — ideal for garden beds, reducing evaporation by up to 60% vs. sprinklers. Sub-surface drip is the most efficient but hardest to access for repairs. Match the system to your garden zones.

Reticulation is the term used in Western Australia for automated garden watering systems — functionally identical to irrigation. Reticulation typically refers to sprinkler-based systems (as distinct from drip irrigation). The rest of Australia uses 'irrigation' as the umbrella term. A reticulation specialist in Perth performs the same work as an irrigation contractor elsewhere.

Irrigation systems that connect to the mains water supply (council tap) via a backflow prevention device require a licensed plumber to install the connection. Once connected, irrigation pipe work and sprinkler installation can be done by an unlicensed irrigation contractor. Installing a bore pump and bore water system requires additional approvals in most states.

Smart irrigation controllers (Hunter, Rain Bird, Gardena, RainBird) connect to Wi-Fi and adjust watering schedules automatically based on weather forecasts, soil moisture sensors, and seasonal programs. They can save 30–50% on water bills versus a manual timer. Some models (like Rachio or Hydrawise) integrate with Google Home and Amazon Alexa.
