Soil Moisture Sensors
Gainesville Regional Utilities, in partnership with the St. Johns River Water Management District, is conducting a trial of soil moisture sensors among residential customers who use large amounts of water for irrigation. Two groups of customers will have a soil moisture sensor and new controller installed with their automatic irrigation systems. Water usage befornd after the installation will be monitored. Soil moisture sensors should help reduce water use, while maintaining healthy home landscapes.
If you use an in-ground, automatic irrigation system, you can use a soil moisture sensor to conserve water. This helps maintain our natural resources, and can also can keep your lawn and shrubs healthier, and save money on your water bill.
A soil moisture sensor is buried in the soil and measures how much moisture is in the root zone. It allows your irrigation system to better match the amount of water applied with the amount needed by the plants. It allows irrigation if more water is needed or prevents irrigation if the soil is already wet from rainfall.
By not watering when your soil has enough moisture, you can significantly
reduce the amount of water used for irrigation. This saves you money, and
as importantly, withdraws less fresh water from our aquifer, saving it for
