The first step to conservation
Understanding Your Water Usage
Landscape irrigation auditing is an effective tool for maximizing water use efficiency in urban landscapes such as home lawns, commercial properties and sports fields. An audit can be used to improve the efficiency of existing irrigation systems.
Irrigation audits consist of three main activities: site inspection, performance testing, and irrigation scheduling. Each activity in itself can result in significant water and cost savings. Together, these activities provide landscape maintenance personnel with a customised irrigation program based on site specific conditions and irrigation system performance.
Over time, even the most efficiently designed irrigation system will begin break down. In absence of a regular maintenance program, minor operation and performance problems can continue for months resulting in excessive water use and poor efficiency, which can reduce plant quality.
Sunken sprinkler heads that do not “pop-up” properly, misaligned spray patterns that throw water onto streets, sidewalks or hardscapes, and broken or missing sprinkler heads resulting from vandalism or mower damage can result in significant water waste.
Performance problems are often inherent in an irrigation system. A sprinkler system where the heads are spaced too far apart will result in poor water distribution and/or dry (or “hot”) spots on the landscape. In order to compensate for this poor uniformity, the system is often set to operate longer, which in turn over-waters most of the landscape.Insufficient or excessive operating pressure will also lead to high water loss through wind drift or poor coverage. Low water pressure is generally caused by insufficient static pressure and/or high pressure losses through valves, meters, piping and other components of the irrigation system.
Visual indications of low water pressure include large water droplets and short sprinkler throw. High water pressure, on the other hand, indicates an absence of proper pressure regulation devices. High pressure is generally characterized by excessive misting of water that is easily evaporated or carried by the wind.
- Measure how much water you use for your landscape
- Highlight leaks, waste and opportunities for conservation
- Create an economically viable action plan to reduce your water use
