How much $ can you save on irrigation costs after just 1 inch of rain?

residential wateringA one-inch rainfall event delivers approximately 7,000 gallons of rainwater to a 10,000 square-foot lot. That free rainfall is equal to $20 – $70 in potable water irrigation costs, depending on your total monthly water use. A rain sensor will do the work and the saving for you.

A rain sensor is a device or switch that overrides the automatic irrigation system when rainfall occurs. The sensor temporarily shuts off a system if it is operating during a rain shower or is scheduled to run following rainfall. If you have an automatic irrigation system without a sensor, the City of Tampa will provide one at no charge ($30 value) to residents. Request a rain censor using your City of Tampa Utility account number.

You may install the sensor yourself or have it installed. You are responsible for the installation cost.Florida Law (Section 373.62 F.S.) requires that all irrigation systems be outfitted with a working rain shut-off device or other technology to inhibit or interrupt operation of the irrigation system during periods of sufficient moisture. To ensure proper operations, sensors should be checked at least once annually.
