Water Conservation Tips

1. Use flow control devices:

Install valves with flow control that allow you to better manage the flow of your system and prevent run-off.

2. Use an automatic shut-off device on every system

Adding an automatic shut-off device can result in 15-20% in water savings. Install an automatic shut-off device like a rain sensor or moisture sensor on every system. These devices automatically shut-off the controller when it is raining or when sufficient soil moisture is reached. They prevent over-watering and the bad publicity that results from sprinklers running when it rains.

3. Always install an automatic controller with water-conserving functions

The following are some of the key features currently available in controllers for maximum flexibility and water efficiency:

Multiple start times

This allows several shorter and more precise run times to prevent run-off and puddles.

Multiple independent programs

This allows the watering schedule to be divided into smaller, more precise watering schedules to accommodate the watering needs of different types of plant life

Water Budget

This provides easy and flexible adjustments to the amount of water used for irrigation.

Rain Delay

This allows the user to pause a watering schedule when irrigation isn’t needed and resume watering when appropriate.

Cycle + Soak

This applies water at a rate that the soil can accept, reducing erosion, run-off, and waste.

Flow Management

Flow sensors enable the controller to detect system problems like line breaks or broken sprinklers and shuts down irrigation to the affected zones to prevent water waste.

ET Programming

This enables the controller to calculate daily evapotranspiration (ET) values and adjust the station run times to replace only the water used by the plants. This maintains a healthy landscape while minimizing water use.

For complete system automation on commercial sites, consider a central control system

Central control systems show annual water savings of 25 – 30% on average. A central control system operates a single or multiple controllers, sensors and other irrigation devices from one central location. It contains all of the functions listed in the Controller section above plus additional sensors that monitor and control environmental conditions automatically and without the need for personal intervention. See Rain Bird’s website for testimonials and cost/water savings examples using central control systems

Set sprinklers to water early in the morning

Set up systems to irrigate between 5 a.m. and 10 a.m. Early in the morning is the most efficient time to water because water can reach its destination without being evaporated by the sun or blown away by the wind. This will also save landscapes from disease caused by water sitting on plants overnight and prevents compaction caused by heavy traffic on wet soils.
