# 5 Easy Steps to Calculate Water Savings

## Estimated Water Savings Using Rain Bird 5000/5000 Plus PRS Series Rotors

Rain Bird's 5000 PRS and 5000 Plus PRS in-stem pressure regulator ensures maximum nozzle performance, even with varying inlet pressures. By maintaining constant optimum pressure of 3,1 bar at the nozzle, 5000/5000Plus PRS rotors end misting and fogging caused by high pressures. For you that means water savings.

Enter the information from your system below and see how much water you can save:

 Calculate your estimated cost savings: Step 1: Enter the pressure (bar) at the nozzle (between 3,1 bar and 5,2 bar): (Either enter the average dynamic pressure for the rotor on one zone or enter the average dynamic pressure for all the rotors on the entire system. If the dynamic pressure is not available, enter the system's static pressure. The static pressure will overstate the water savings, but it will still provide an estimate of the potential water savings.) Step 2: Enter the flow (m3/h) @ 3,1 bar:  (If you entered the pressure for one zone above, enter the flow (m3/h) for that zone. If you entered the pressure for the entire system above, enter the flow (m3/h) for the entire system). Step 3: Enter Average Watering Time per Day (min.): Step 4: Enter Average Number of Watering Days per Week: Step 5: Enter Average Watering Weeks per Year:

 The initial system waste is: flow (m3/h) The yearly water savings is*: m3

* (Due to varying conditions, your actual cost savings may be different. This formula is designed solely as a basis for estimating potential savings.)
