Leaks in irrigation systems can increase your water bill by between 20% and 50%. This increase is due to the fact that water seeps out without being visible, making it difficult to detect. In this article, we will explore the warning signs you can identify in your garden and the factors that contribute to these losses, providing you with effective solutions to keep your garden healthy and your prices under control.
The Impact of an Invisible Leak in the Garden
In Marina Alta and Costa Blanca, maintaining Mediterranean gardens requires complex irrigation systems. A broken pipe in the irrigation sector can go unnoticed for months because the water seeps directly into the ground. However, the consequences are not just economic.
Warning Signs You Should Not Ignore:
- Suspiciously green areas or muddy spots when the rest of the garden is dry.
- Loss of pressure in the farthest sprinklers.
- Slight depressions in the ground or the appearance of holes near the solenoid valves.
- Water bills that do not correspond to usual consumption.
Why Do Automatic Irrigation Systems Fail?
There are several risk factors in our area that accelerate the deterioration of installations:
- Tree Roots: Roots seek the constant moisture of irrigation and end up strangling or perforating the polyethylene.
- Nighttime Overpressure: Many irrigation systems operate at night when the network pressure is higher, causing breaks in elbows and joints.
- Temperature Cycles: The thermal contrast of the soil can weaken materials over the years.
The Telefuga Solution: Geophone and Gas Location
In the past, locating an irrigation leak meant digging trenches all over the garden, destroying the grass and plants. At Telefuga, we apply the same precision techniques as in swimming pools:

Electronic Listening (Geophony)
We use highly sensitive geophones to capture the sound vibration produced by water escaping under pressure. Our technicians can "hear" the leak through the ground, allowing them to mark the repair point with minimal error margin.
Technical Data:
Even a small leak of 2 liters per minute represents a waste of 2,880 liters per day. In a month, you will have wasted more water than an entire family consumes.
Prevention Tips for 2025
Prevention is your best ally. Follow these guidelines to keep your irrigation efficient:
- Check the solenoid valve pits monthly to rule out accumulated moisture.
- Install a smart pulse counter that alerts you on your mobile if there is consumption outside of scheduled times.
- Conduct a hydraulic audit if you notice that the bill rises without explanation.
Don’t let everyone’s water be lost underground. If you suspect a leak, act today.
