Frequently Asked Questions
What's the most water-efficient irrigation system?
Drip irrigation is the most water-efficient system, achieving 90-95% efficiency compared to 75-85% for sprinkler systems. It delivers water directly to plant root zones, reducing evaporation and runoff, making it ideal for gardens, flower beds, and vegetable patches.
How long does irrigation installation take?
A typical residential system takes 2-5 days depending on size and complexity. Small garden systems (under 100m²) can be completed in 1-2 days, while larger multi-zone systems with smart controllers may take up to a week including system commissioning and testing.
Do I need council approval for irrigation installation?
Basic irrigation systems using mains water typically don't require council approval. However, bore installations, large commercial systems, or connections near waterways may need permits. Always check with your local council and water authority before starting major installations.
What maintenance do irrigation systems require?
Regular maintenance includes cleaning filters (monthly), checking emitters and sprinkler heads (seasonally), adjusting watering schedules, and winterizing in cold climates. Professional annual services cost $150-$400 and include system optimization and component replacement.
Can irrigation systems work with rainwater tanks?
Yes, irrigation systems can be designed to work with rainwater tanks, often requiring a pump system to maintain adequate pressure. This setup can reduce mains water usage by 30-70% and may qualify for rebates in some areas. Additional filtration may be needed for drip systems.
How much water will my irrigation system use?
Water usage depends on system type, garden size, plant requirements, and climate. A typical suburban garden uses 200-500L per week during peak season. Drip irrigation can reduce consumption by 30-50% compared to manual watering, while smart controllers optimize usage based on weather conditions.
