Landscape irrigation auditing is an effective tool for maximizing water efficiency in landscape irrigation. Audits can help landscape owners save considerable money and as much as half the water previously used by their irrigation systems.
Audits of Existing Irrigation Systems
An existing irrigation system audit generally consists of a detailed analysis of these factors:
Performance Evaluation
Even well-designed and properly installed irrigation systems degrade over time. Certified Landscape Irrigation Auditors are trained to look for the following problems;
- Valve Malfunctions
- Low Pressure
- High Pressure
- Tilted Sprinklers
- Spray Deflection
- Sunken Sprinklers
- Plugged Equipment
- Arc Misalignment
- Low Sprinkler Pressure
- Leaky Seals or Fittings
- Lateral or Drip Line Leaks
- Missing or Broken Heads
- Slow Drainage or Ponding
- Compaction/Thatch/Runoff
