Certified Irrigation Audits
Water Wise is a certified irrigation auditor. We use the Irrigation Association’s set of minimum guidelines and standardized procedures to perform audits of landscape irrigation systems. We have been helping improve the efficiency of existing irrigation systems for over 50 years. After each audit is performed we provide the following detailed information to the property owner:
- Site Collection Data
- Maintenance Recommendations & Repairs
- Field Measurements & Observations
- Irrigation Uniformity & Efficiency
- Basic Irrigation Schedule
- Irrigation Water Usage Management Instructions
An irrigation audit is an extremely effective tool for maximizing water use efficiency in urban landscapes such as home lawns, commercial properties and sports fields. They can save property owners hundreds and even thousands of dollars each year. Water Wise's landscape irrigation audits consist of three main activities:
- Site Inspection
- Performance Testing
- Irrigation Scheduling
Each activity in itself can result in significant water and cost savings. Together, these activities will provide you with a customized irrigation program based on site specific conditions and irrigation system performance. Water Wise not only has the ability to outline the needs to repair or upgrade existing systems, but to create and install new high performing irrigation systems, as well as provide information for managing the system in the future. Water Wise also uses the Irrigation Association’s set of minimum guidelines and standardized procedures to perform an audit of the landscape irrigation system.
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.
Sprinkler application devices, including pop-up spray heads, rotors, micro-sprays and bubblers are designed to operate within specific operating pressures and head spacing. Manufacturer’s specifications catalogs rate the performance, mainly flow rate (in gallons per minute) and precipitation rate (in inches per hour), based on these parameters. Commonly, the rated performance listed in the catalogs does not accurately represent actual performance.
For irrigation scheduling purposes, the most accurate determination of precipitation rate is achieved by conducting catch can tests. Catch can tests measure the amount of water that actually hits the ground at various points within the landscape, and also serves to measure application uniformity. Since irrigation systems commonly use different types and brands of sprinklers, it is important to conduct catch can tests for each individual zone or “station” on an irrigation system.
The following can be determined per each valve that is audited:
- Precipitation output
- Distribution uniformity
- Flow rates, pressures, & spacing
- Product information
- Irrigation Soil Moisture Schedule for High Quality Turf (weekly, monthly, yearly, or seasonally), ET (Evapotransformation & weather) referenced.
