Sports fields are often the focal point of a facility and take the most irrigation per square foot to maintain. Because you want to keep fields in premium condition, there are fewer options for water conservation than with the typical landscape turf. Here are six simple adjustments that can save water without compromising turf quality.
Tip #1—Know The System
The first step in improving irrigation efficiency is getting to know the system. For schedule planning, know what type of area each control valve is watering and the precipitation rate. Make a list of each valve and the zone conditions. Is it a full circle or part circle? Is it a sideline zone or a centerfield zone? Is it full sun or partial shade? This information will help determine how much water is needed.
To determine runtimes, you will also need the precipitation rates for each zone. There are several ways to determine these. The most direct way is to use catch cans or rain gauges to measure sprinkler output. This can be done by a certified irrigation auditor in the area, or you can do it yourself. Many sprinkler manufacturer and irrigation distributor websites provide a step-by-step process for conducting an audit and determining precipitation rates.
